| Performance Narrative [Text Block] | How a fund's returns vary from year to year can give an idea of its risk.Past performance may not indicate future results. All performance figures below assume that dividends were reinvested. The 7-day yield, which is often referred to as the “current yield,” is the income generated by the fund over a seven-day period. This amount is then annualized, which means that we assume the fund generates the same income every week for a year. For more recent performance figures, go to dws.com (the Web site does not form a part of this prospectus) or call the phone number included in this prospectus. This information does not reflect fees associated with the separate account that invests in the fund or any variable life insurance policy or variable annuity contract for which the fund is an investment option. These fees will reduce returns.Prior to May 2, 2016, the fund operated as a prime money market fund that had the ability to invest in certain types of securities that the fund is no longer permitted to hold to any significant extent (i.e., over 0.5% of total assets). Consequently, the performance information below may have been different if the fund’s current investment limitations had been in effect during the period prior to the fund’s conversion to a government money market fund. |
