Risks [Table Text Block]
 
RISKS
LOCATION IN
PROSPECTUS
Is There a Risk of
Loss from Poor
Performance?
Yes, you can lose money by investing in this Contract, including
loss of principal.
Is this a
Short-Term
Investment?
No, this Contract is not a short-term investment and is not
appropriate for an investor who needs ready access to cash.
In particular:
Tax deferral is more beneficial to Participants with a long-term
investment time horizon.
Withdrawals are subject to ordinary income tax and may be
subject to tax penalties.
The Contract is not intended for those who may need to make
early or frequent withdrawals or intend to engage in frequent
trading in the Underlying Funds.
What Are the
Risks Associated
with the
Investment
Options?
An investment in the Contract is subject to the risk of poor
investment performance, and can vary, depending on the
performance of the Underlying Funds. Each investment option
available under the Contract, including the General Account, will
have its own unique risks. You should review these Investment
Alternatives before making an investment decision.
What Are the
Risks Related to
the Insurance
Company?
An investment in the Contract is subject to the risks related to
Mutual of America, including that any obligations (including
under the General Account), guarantees, and benefits of the
Contract are subject to the claims paying ability of Mutual of
America. More information about Mutual of America, including its
financial strength ratings, is available upon request from Mutual
of America by calling our toll-free number, 800.468.3785 or by
visiting our website at mutualofamerica.com.
Investment Restrictions [Text Block] Yes, your ability to allocate Contributions among the Investment Alternatives is subject to any restrictions contained in your Employer’s Plan. If your Employer’s Plan permits transfers to other contracts, you may transfer your Account Value but only to a provider specifically identified in the Plan. Transfers while you are actively employed to any provider not specified in the Plan are prohibited.We may remove an Underlying Fund or limit its availability to new Contributions and/or transfers of Account Value if we determine that an Underlying Fund no longer satisfies one or more of our selection criteria.
Key Information, Benefit Restrictions [Text Block] Yes, to the extent your Employer’s Plan allows participant loans, you have the right to borrow using your Account Value as collateral security for the loan or, if your Employer’s Plan provides for loans to be made using a trust, you will withdraw the loan amount from your Account Value. Your Employer’s Plan may or may not permit loans to be taken from or secured by amounts held in a Designated Roth Account. The maximum amount that can be taken as a loan is limited under the Code, based on your account balance. Generally, a Participant can borrow no more than the lesser of (a) the greater of $10,000 or 50% of the Participant’s vested account balance; or (b) $50,000. The maximum amount that a Participant can borrow is also limited if the Participant has another outstanding loan. Certain exceptions may permit a Participant to take a larger loan under circumstances specified by law from time to time.We will not permit you to make withdrawals or transfers of the collateral amount while the loan is outstanding. Amounts borrowed in a loan do not participate in the Subaccount investment experience. Loans, therefore, can affect the Account Value and death benefit whether or not the loan is repaid. Death benefit proceeds payable will be reduced by the amount of any outstanding Contract loan plus accrued interest.
Tax Implications [Text Block] You should consult with a tax professional to determine the tax implications of an investment in and Contributions made under the Contract.Because the Contract is purchased through a tax-qualified plan, there are no additional tax benefits to the Contract.Withdrawals will be subject to ordinary income tax, and may be subject to tax penalties.
Investment Professional Compensation [Text Block] Mutual of America offers the Contracts for sale through certain of our employees who are registered representatives of Mutual of America Securities LLC, the principal underwriter of the Contracts. The only compensation we pay to registered representatives for sales of the Contracts is in the form of salary, plus annual incentive compensation based on achievement of certain individual and/or Company sales objectives. There are no commissions or fees payable for sales of the Contracts.With regard to non-cash compensation, representatives and certain staff from the top performing regional offices, as well as other high performing representatives, are eligible to attend a trip to a Company-hosted sales conference or other Company-hosted event.The existence of such forms of compensation could influence a Contract over another investment.
Exchanges [Text Block] Registered representatives may have a financial incentive to offer a participant a new contract in place of the one the participant already owns. A participant should only exchange their Contract if the participant determines, after comparing the features, fees, and risks of both contracts, that it is preferable for the participant to purchase the new contract rather than continue to own the existing contract.

This Example below is intended to help you compare the cost of investing in the Subaccounts with the cost of investing in other variable annuity contracts. These costs include transaction expenses, Annual Contract Fees, Base Contract Expenses, and Underlying Fund fees and expenses and exclude Loan fees. The Example assumes that you invest $100,000 under a Contract for the time periods indicated and that all Account Value is allocated to the Subaccounts. We do not impose a surrender charge when you make a withdrawal of Account Value. As a result, the expenses would be the same whether or not you surrender the Account Value, or apply the Account Value for the purchase of an annuity (annuitize), at the end of the applicable time period. The Example also assumes that your investment has a 5% annual rate of return each year and assumes the maximum Underlying Fund Fees and Expenses, the maximum Annual Contract Fee, the maximum Base Contract Expenses and optional benefits available for an additional charge. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Item 5. Principal Risks [Line Items]  
Item 5. Principal Risks [Table Text Block]
Principal Risks of Investing in the ContractContract Risks You can lose money in a variable annuity, including potential loss of your original investment. The value of your investment and any returns will depend on the performance of the Underlying Funds you have selected. We reserve the right to make certain changes to the structure and operation of the Subaccounts at our discretion and without your prior consent. We may add, delete, or substitute Subaccounts for contractholders and new or substitute Subaccounts may have different fees and expenses or be offered to only certain classes of contractholders. For more information, see the “Contract or Separate Account Changes” section in the Prospectus. The Contracts are designed for Participants with a long investment time horizon. They are not intended for those who may need to make early or frequent withdrawals or intend to engage in frequent trading in the Underlying Funds. Your ability to make withdrawals while you are an active participant in a Plan will be limited. The Contract is not suitable as a short-term investment. Investment Risk You bear the risk of any decline in the Account Value caused by the performance of the Underlying Funds held by the Subaccounts. The Underlying Funds may not achieve their investment objectives, and your Account Value allocated to any of the Subaccounts may decline in value, perhaps significantly. Each Underlying Fund may have its own unique risks and the risk of loss varies with each Underlying Fund. The investment risks are described in the prospectuses for the Funds. Insurance Company Risk An investment in the Contract is subject to the risks related to Mutual of America, including that any obligations (including under the General Account), guarantees, and benefits of the Contract are subject to the claims paying ability of Mutual of America. Accordingly, if Mutual of America experiences financial distress in the future or becomes insolvent, we may not be able to meet our obligations with respect to the Contract, including Account Value allocated to the General Account. Moreover, General Account assets are exposed to the risks normally associated with a portfolio of fixed-income securities, including interest rate, liquidity and credit risk, and are also subject to the claims of our general creditors. More information about Mutual of America, including its financial strength ratings, is available upon request from Mutual of America. Loans Amounts borrowed in a Collateralized Loan or Uncollateralized Loan do not participate in the Subaccount investment experience. Loans, therefore, can affect the Account Value and death benefit whether or not the loan is repaid. Death benefit proceeds payable will be reduced by the amount of any outstanding Contract loan plus accrued interest. A deemed distribution due to your default on a loan may be subject to taxes and tax penalties. Tax Consequences Except for Designated Roth Accounts, withdrawals are generally taxable, and prior to age 59½ a tax penalty may apply. In addition, even if the Contract is held for years before any withdrawal is made, withdrawals are taxable as ordinary income rather than capital gains. Different rules apply for Designated Roth Accounts. Business Disruption and Cybersecurity Risks We rely heavily on interconnected computer systems and digital data to conduct our business activities. Because our business is highly dependent upon the effective operation of our computer systems and those of our business partners, our business is vulnerable to disruptions from utility outages, and susceptible to operational and information security risks resulting from information systems failure (e.g., hardware and software malfunctions), and cyber-attacks. These risks include, among other things, the theft, misuse, corruption and destruction of data maintained online or digitally, interference with or denial of service, attacks on websites and other operational disruption and unauthorized release of confidential Participant information. Such systems failures and cyberattacks affecting us, the Underlying Funds, intermediaries and other affiliated or third party service providers may adversely affect us and your Account Value. For instance, systems failures and cyberattacks may interfere with our processing of Contract transactions, including the processing of orders from our website or with the Underlying Funds, impact our ability to calculate accumulation unit values and Participant Account Value, cause the release and possible destruction of confidential customer or business information, impede order processing, subject us and/or our service providers and intermediaries to regulatory fines and financial losses and/or cause reputational damage. Cybersecurity risks may also impact the issuers of securities in which the Underlying Funds invest, which may cause the Underlying Funds to lose value. In addition, the risk of cyberattacks may be higher during periods of geopolitical turmoil. There can be no assurance that we or the Underlying Funds or our service providers will avoid losses affecting your Account Value due to cyberattacks or information security breaches in the future. We are also exposed to risks related to natural and man-made disasters and catastrophes, such as, but not limited to, storms, fires, floods, earthquakes, epidemics, pandemics, malicious acts, acts of war, and terrorist acts, which could adversely affect our ability to conduct business. A natural or man-made disaster or catastrophe, including a pandemic, could affect the ability, or willingness, of our workforce and employees of service providers and third party administrators to perform their job responsibilities. Catastrophic events may negatively affect the computer and other systems on which we rely and may interfere with our processing of Contract-related transactions, including processing of orders from Participants and orders with the Underlying Funds, impact our ability to calculate Account Value, or have other possible negative impacts.

Name of Benefit [Text Block] Death benefit during Accumulation Period equal to Account Value
Operation of Benefit [Text Block] Death Benefit During the Accumulation Period
We will pay a death benefit to your designated Beneficiary if you die during the Accumulation Period. If you are married, your Eligible Spouse must be the Beneficiary unless you designated a different Beneficiary with the written consent of your Eligible Spouse. We will pay the death benefit after we have received the following at our Home Office: due proof of death, generally a certified copy of your death certificate; notification of election by the Beneficiary(ies) of the form in which we are to pay the death benefit; and claim forms and other information and documents that we inform the Beneficiary are necessary for us to process the death benefit request. The amount of the death benefit will be your Account Value, less outstanding loans and interest, as of the date on which we receive the items listed above. Until then, your Account Value will remain allocated as it was on the date of death. If you have more than one Beneficiary, each Beneficiary’s share of the Account Value will remain allocated as it was on the date of death until we receive the items listed above from such Beneficiary. Each Beneficiary will continue to bear the risk of loss of their share of the death benefit until their claim is processed. Form of Death Benefit Payment. The Beneficiary will elect the form of death benefit as described below. The Code imposes special requirements on the payment of a death benefit and specifies the time period in which we must pay it. We will pay the death benefit in a single sum if a Beneficiary does not select an option by the date the Code requires a payout to be made. In addition, Participants must begin taking minimum distributions after they reach a certain age (called the Required Beginning Date or Required Distribution Date), and certain requirements depend on whether you had reached that age at the time of death. Beneficiaries should consult their tax advisers for any additional rules that may apply in their particular circumstances. See “Minimum Required Distributions” under “Taxes.” In general, any method of distribution that a Beneficiary selects must comply with one of the following. (a) Ten Year Rule. In the case of a death occurring in 2020 or later, the general rule is that we must pay the entire death benefit to the Beneficiary by December 31 of the calendar year that is ten calendar years after the Participant’s death, unless we pay the benefit under (b), (c) or (d) below. (b) Exception for Eligible Designated Beneficiaries. An Eligible Designated Beneficiary, as defined below, may choose to have the entire death benefit distributed in the form of Annuity Payments that begin within one year of the Participant’s death and are payable over a period of time that is not more than the Beneficiary’s life or life expectancy, whichever is longer. For these purposes, an Eligible Designated Beneficiary is a Beneficiary who, at the time of the Participant’s death, is also (a) the Participant’s surviving spouse; (b) the Participant’s minor child; (c) an individual who is no more than 10 years younger than the Participant; (d) a qualifying disabled individual; or (e) a qualifying chronically ill individual. Notwithstanding the foregoing, if the Eligible Designated Beneficiary is a minor child, distributions must be paid in full no later than the end of the tenth year following the child’s attainment of the age of majority. (c) Beneficiary is the Eligible Spouse. Special rules apply if the only Beneficiary is your surviving Eligible Spouse. A Beneficiary who is also your Eligible Spouse may use your Required Beginning Date for determining when minimum distributions must begin. As a consequence, the Beneficiary does not have to begin receiving benefits until no later than your Required Beginning Date, which beginning in 2023 is the later of April 1 of the year following the year you reached age 73 if still alive. Alternatively, a Beneficiary who is also an Eligible Spouse, may roll your account balance over to his or her own qualified plan or 403(b) plan or to his or her own eligible IRA. (d) Special Rule for Beneficiaries that are Not Individuals. If your Beneficiary is not an individual, such as your estate or certain types of trusts, we must pay the entire death benefit to the Beneficiary by December 31 of the calendar year that is five calendar years after your death. However, if you die after reaching your Required Beginning Date, the Beneficiary is limited to distributions made over your remaining life expectancy. A Beneficiary under more than one 403(b) plan may take withdrawals from one or more such plans, in accordance with applicable IRS regulations, if permitted by the Plan. Death Benefit After Annuity Commencement Date
If you (and your joint Annuitant if the form is a joint annuity) were to die on or after the Annuity Commencement Date and annuity payments have begun, your Beneficiary will receive the benefit (if any) provided by the form of annuity under which Annuity Payments were due. If you elect a form of annuity that does not provide for a certain period or full cash refund, then no payments or death benefit will be due following the death of the Annuitant (and the joint Annuitant, as applicable) after the Annuity Commencement Date. Evidence of Survival. When payment of a benefit is contingent upon the survival of any person, we may require that evidence of that person’s survival be furnished to us, either by personal endorsement of the check drawn for payment, or by other means satisfactory to us. If satisfactory evidence of survival is not received by us within 30 days following our request for it, we may suspend benefit payments until such evidence is received. Misstatement of Information. If we pay a benefit under a Contract based on information that you or a Beneficiary misstated to us, we will recalculate the benefit when we learn of the misstatement. We will adjust the amount of the benefit payments, or the amount applied to provide the benefit, or both, to the proper amount we determine based on the corrected information. If we underpaid benefits due to any misstatement, we will pay the amount of the underpayment in full with the next payment due under the Contract. If we overpaid any benefits due to a misstatement, we will deduct the overpayment to the extent possible from payments as they become due under the Contract. We will include interest on the amount of any underpayments or charge interest on overpayments, at the effective rate set forth in the Contract or as may be required under state insurance law provisions. Information and Determination. Contractholders and Participants, as appropriate, must furnish us with the facts and information that we may require for the operation of the Contract including, upon request, the original or photocopy of any pertinent records held by the Contractholder or Participant. A Contractholder should report to us any determination that the Contractholder or employer makes pursuant to the terms of the Plan. We may rely on reports and other information furnished by Contractholders, employers or Participants and are not obligated to inquire as to the accuracy or completeness of such reports and information. Non-Alienation of Benefits. To the extent permitted by law (a) no amount payable with respect to you may be subject to alienation, attachment, garnishment, levy (other than a federal tax levy or a Qualified Domestic Relations Order), execution, or other legal or equitable process, and (b) no such amount will in any way be subject to any legal process that would subject it to the payment of any claim against you or a Beneficiary.

Operation of Benefit [Text Block] To the extent your Employer’s Plan allows participant loans, you have the right to borrow using your Account Value as collateral security for the loan or, if your Employer’s Plan provides for loans to be made using a trust, you will withdraw the loan amount from your Account Value. Your Employer’s Plan may or may not permit loans to be taken from or secured by amounts held in a Designated Roth Account. The maximum amount that can be taken as a loan is limited under the Code, based on your account balance. Generally, a Participant can borrow no more than the lesser of (a) the greater of $10,000 or 50% of the Participant’s vested account balance; or (b) $50,000. The maximum amount that a Participant can borrow is also limited if the Participant has another outstanding loan. Certain exceptions may permit a Participant to take a larger loan under circumstances specified by law from time to time. A “trusteed loan,” or Uncollateralized Loan, is a loan made through the trustee of the Plan. A “non-trusteed loan” is a loan made directly to a participant. Non-trusteed loans require collateral, and may be referred to as Collateralized Loans. Collateralized Loans are loans for which security in the amount of 120% of the loan amount is required to be transferred into the General Account and held against repayment of the loan. Trusteed loans are uncollateralized (and may be referred to as Uncollateralized Loans) and the loan amount is withdrawn from the Account Value and is paid to the participant directly. For Uncollateralized Loans, the application for the loan is generally submitted to a trustee or trustees appointed by your employer, who is responsible for the approval, administration and collection of loans to Participants in the employer’s Plan. For Collateralized Loans, you are required to transfer an amount equal to 120% of the loan from the Separate Account to the General Account unless you already have allocated the necessary amount of your Account Value to the General Account to serve as collateral security for repayment of the loan. The amount withdrawn from each Investment Alternative that comprises your Account Value for the transfer of collateral security or the withdrawal for a trusteed loan will be withdrawn proportionally from all Investment Alternatives in your account at the time of the request, unless you instruct us otherwise. We will not permit you to make withdrawals or transfers of the collateral amount while the loan is outstanding. There are no tax consequences to you from obtaining a loan, unless you do not make repayments when they are due. For a Collateralized Loan, you can only borrow to the extent that you have allocated a sum equal to 120% of the loan amount to the General Account. If you do not have 120% of the loan amount (in addition to sums already serving as collateral for other loans) in the General Account and do not allocate additional amounts to the General Account from your Account Value allocated to other Investment Alternatives to achieve such 120%, you cannot borrow that loan amount. We do not transfer amounts to the General Account for purposes of satisfying the collateral requirement on your behalf unless we are instructed by you to transfer from other Investment Alternatives to the General Account. The interest rate for a Collateralized Loan is 3% higher than the General Account interest rate credited to amounts held in the General Account as collateral security. For Collateralized Loans, you will pay interest on the loan, but the amount we hold in the General Account as collateral for your loan will accrue interest. The amount held in the General Account as collateral for a loan that is a Collateralized Loan may earn interest at a rate different and lower than the rates earned by other amounts in the General Account and the interest it earns may be lower than the returns of some or all of the Subaccounts. For Uncollateralized Loans, the loan amount is withdrawn from your Account Value. The interest rate for an Uncollateralized Loan is the Prime Rate +1%, which you pay to your Account. As such, we do not receive any portion of the interest paid. For uncollateralized loans, where a Trustee has been appointed, (a) for loans repaid by payroll deduction we charge a non-refundable origination fee of $75.00 and a non-refundable annual fee of $15.00 per year and (b) for loans paid through Home Billing we charge a non-refundable origination fee of $350.00. The origination fees, and the annual fees through the stated maturity of an uncollateralized loan repaid by payroll deduction, are collected at the time the loan is originated and deducted from the loan proceeds. These fees are non-refundable and will not be returned if the loan is repaid in advance of the stated maturity date. The interest rate for each loan you take is determined at the time you take the loan and remains fixed for the life of that loan. Payments of principal and interest that are not made by payroll deduction are due at least quarterly. The due dates for payments of principal and interest made by payroll deduction will be based on your employer’s payroll frequency. Any loan shall be repaid within five years, except a loan used to purchase a primary residence of the Participant may be repaid over a period not to exceed ten years. Your repayment schedule will provide for substantially level amortization of the loan over the applicable period, which means that your payments will be substantially equal (subject to changes in the interest rate on your loan. If your Plan permits, you may be able to take out larger loans and have extended repayment periods if you have been affected by a federally-declared disaster). Your payments will be by payroll deduction in accordance with your payroll schedule or as otherwise permitted by the Code. If you terminate your employment while a loan remains outstanding, treatment of your loan will be dictated by the terms of the Plan and your employer's loan program. All Plans require authorization by the Employer or third party administrator, as applicable, for Participant loans. Amounts borrowed in a Collateralized Loan or Uncollateralized Loan do not participate in the Subaccount investment experience. Loans, therefore, can affect the Account Value and death benefit whether or not the loan is repaid. Death benefit proceeds payable will be reduced by the amount of any outstanding Contract loan plus accrued interest.

Thrift Plan Contracts | Contract Risks  
Item 5. Principal Risks [Line Items]  
Principal Risk [Text Block] Contract Risks You can lose money in a variable annuity, including potential loss of your original investment. The value of your investment and any returns will depend on the performance of the Underlying Funds you have selected. We reserve the right to make certain changes to the structure and operation of the Subaccounts at our discretion and without your prior consent. We may add, delete, or substitute Subaccounts for contractholders and new or substitute Subaccounts may have different fees and expenses or be offered to only certain classes of contractholders. For more information, see the “Contract or Separate Account Changes” section in the Prospectus. The Contracts are designed for Participants with a long investment time horizon. They are not intended for those who may need to make early or frequent withdrawals or intend to engage in frequent trading in the Underlying Funds. Your ability to make withdrawals while you are an active participant in a Plan will be limited. The Contract is not suitable as a short-term investment.
Thrift Plan Contracts | Investment Risk  
Item 5. Principal Risks [Line Items]  
Principal Risk [Text Block] Investment Risk You bear the risk of any decline in the Account Value caused by the performance of the Underlying Funds held by the Subaccounts. The Underlying Funds may not achieve their investment objectives, and your Account Value allocated to any of the Subaccounts may decline in value, perhaps significantly. Each Underlying Fund may have its own unique risks and the risk of loss varies with each Underlying Fund. The investment risks are described in the prospectuses for the Funds.
Thrift Plan Contracts | Loans Risk  
Item 5. Principal Risks [Line Items]  
Principal Risk [Text Block] Loans Amounts borrowed in a Collateralized Loan or Uncollateralized Loan do not participate in the Subaccount investment experience. Loans, therefore, can affect the Account Value and death benefit whether or not the loan is repaid. Death benefit proceeds payable will be reduced by the amount of any outstanding Contract loan plus accrued interest. A deemed distribution due to your default on a loan may be subject to taxes and tax penalties.
Thrift Plan Contracts | Tax Consequences  
Item 5. Principal Risks [Line Items]  
Principal Risk [Text Block] Tax Consequences Except for Designated Roth Accounts, withdrawals are generally taxable, and prior to age 59½ a tax penalty may apply. In addition, even if the Contract is held for years before any withdrawal is made, withdrawals are taxable as ordinary income rather than capital gains. Different rules apply for Designated Roth Accounts.
Thrift Plan Contracts | Business Disruption and Cybersecurity Risks  
Item 5. Principal Risks [Line Items]  
Principal Risk [Text Block] Business Disruption and Cybersecurity Risks We rely heavily on interconnected computer systems and digital data to conduct our business activities. Because our business is highly dependent upon the effective operation of our computer systems and those of our business partners, our business is vulnerable to disruptions from utility outages, and susceptible to operational and information security risks resulting from information systems failure (e.g., hardware and software malfunctions), and cyber-attacks. These risks include, among other things, the theft, misuse, corruption and destruction of data maintained online or digitally, interference with or denial of service, attacks on websites and other operational disruption and unauthorized release of confidential Participant information. Such systems failures and cyberattacks affecting us, the Underlying Funds, intermediaries and other affiliated or third party service providers may adversely affect us and your Account Value. For instance, systems failures and cyberattacks may interfere with our processing of Contract transactions, including the processing of orders from our website or with the Underlying Funds, impact our ability to calculate accumulation unit values and Participant Account Value, cause the release and possible destruction of confidential customer or business information, impede order processing, subject us and/or our service providers and intermediaries to regulatory fines and financial losses and/or cause reputational damage. Cybersecurity risks may also impact the issuers of securities in which the Underlying Funds invest, which may cause the Underlying Funds to lose value. In addition, the risk of cyberattacks may be higher during periods of geopolitical turmoil. There can be no assurance that we or the Underlying Funds or our service providers will avoid losses affecting your Account Value due to cyberattacks or information security breaches in the future. We are also exposed to risks related to natural and man-made disasters and catastrophes, such as, but not limited to, storms, fires, floods, earthquakes, epidemics, pandemics, malicious acts, acts of war, and terrorist acts, which could adversely affect our ability to conduct business. A natural or man-made disaster or catastrophe, including a pandemic, could affect the ability, or willingness, of our workforce and employees of service providers and third party administrators to perform their job responsibilities. Catastrophic events may negatively affect the computer and other systems on which we rely and may interfere with our processing of Contract-related transactions, including processing of orders from Participants and orders with the Underlying Funds, impact our ability to calculate Account Value, or have other possible negative impacts. These events may also impact the issuers of securities in which the Underlying Funds invest, which may cause the Underlying Funds to lose value. There can be no assurance that we, the Underlying Funds or our service providers will avoid losses affecting your Account Value due to a natural disaster or catastrophe.
