What is a variable annuity?
A variable annuity is a tax-deferred retirement contract with two phases. During accumulation, your premium and ongoing contributions are invested in subaccounts (similar to mutual funds). Growth depends on market returns minus contract fees. During payout (annuitization), the accumulated balance is converted into a stream of periodic payments, often for a fixed number of years or for life. This calculator models both phases and compares accumulation with and without annual fee drag.
For simpler annuity growth without fee modeling, use the annuity calculator. To compare guaranteed immediate income options, see the immediate annuity calculator and pension calculator. For workplace retirement savings outside an annuity contract, try the 401(k) calculator and retirement planning calculator.
Accumulation phase with fee drag
Each year (or month), the account balance grows at the expected return rate, then receives contributions. Variable annuity contracts typically charge mortality and expense (M&E) risk fees, administrative fees, and underlying fund expense ratios. This calculator subtracts the total annual fee ratio from the gross return to model net growth.
Running the same inputs at the gross return (no fees) shows how much fee drag reduces the balance available for annuitization.
Payout phase (annuitization EMI)
After accumulation, the post-fee balance funds a fixed-term payout. Monthly payments use the standard amortization (EMI) formula: equal payments that include both principal return and interest at the expected payout return rate.
Worked example with default inputs
With a $50,000 initial investment, $5,000 annual contributions for 20 years, 7% expected return, and 2% annual fees (5% net), the post-fee accumulated value is about $297,995. Annuitizing that balance over 20 years at a 4% payout return produces roughly $1,806 per month, for total payouts near $433,389. Without fees, the balance would reach about $398,462, a difference of roughly $100,467 in fee drag alone.
