Annuity Calculator

Annuity payments are calculated using the present value of the annuity, the guaranteed interest rate, and the payment period or the annuitant's life expectancy. For a fixed annuity, the insurance company determines how much it can pay each period by spreading your premium plus guaranteed interest over the expected number of payments. A $200,000 immediate annuity for a 65-year-old might produce roughly $1,100 to $1,300 per month depending on current interest rates and the insurer's mortality assumptions. The calculation also factors in whether you select a single-life or joint-life payout and whether the annuity includes a guaranteed minimum payment period.

Fixed annuities guarantee a specific interest rate and predictable payments, making them the simplest and most conservative option. Variable annuities invest your premium in mutual fund-like subaccounts, so your payments fluctuate based on market performance, offering higher growth potential with greater risk. Fixed indexed annuities fall between the two, linking returns to a market index like the S&P 500 while guaranteeing you will never lose principal due to market declines. Each type serves a different purpose: fixed annuities prioritize income certainty, variable annuities target growth, and indexed annuities attempt to capture moderate market gains with downside protection.

An annuity provides guaranteed lifetime income regardless of how long you live or how markets perform, while a systematic withdrawal plan draws down your investment portfolio at a set rate, typically 3.5% to 4% per year. The annuity eliminates longevity risk but sacrifices liquidity and usually forfeits the remaining balance at death. A systematic withdrawal plan preserves full access to your funds and allows you to leave a legacy, but carries the risk of depleting your savings if markets underperform or you live longer than expected. Many retirees use a combination approach, annuitizing a portion of their savings for baseline income while keeping the rest invested for flexibility and growth.

The tax treatment of annuity payments depends on how the annuity was funded. If purchased with pre-tax money from a Traditional IRA or 401(k), the entire payment is taxed as ordinary income. If purchased with after-tax dollars, each payment is split into a taxable earnings portion and a tax-free return of principal using the exclusion ratio. For example, if your total investment was $200,000 and the expected total payout is $300,000, roughly two-thirds of each payment is tax-free until you recover your full investment. Withdrawals taken before age 59½ from a non-qualified annuity may also incur a 10% early withdrawal penalty on the earnings portion.
