Annuity Calculator
Estimate your annuity payout, project deferred growth, and weigh an annuity against keeping the money invested. Three tools in one.
Updated October 2026
The premium you'd pay the insurer (or your current annuity balance)
Starting now? That's an immediate annuity (SPIA). Set this to your current age.
The interest rate the insurer credits while paying you out
Lifetime payouts are modeled to this planning horizon
Ongoing additions during the accumulation phase (deferred annuities)
Growth inside an annuity is tax-deferred until withdrawal
The lump sum you'd either annuitize or keep invested
Annual income as a percent of premium, from an insurer's quote. Payout rates rise with age.

payments recoup the premium
Before you buy: variable annuities often carry 1% to 3% in combined annual fees, and most deferred annuities charge surrender penalties (commonly starting around 7% and declining over 6 to 8 years) if you withdraw early. Ask for the fee table and surrender schedule in writing. Withdrawals of gains before 59½ may also owe a 10% IRS penalty.

Cumulative payments vs your purchase price
Estimates only. Real annuity quotes are priced by insurers using mortality tables, current rates, and any riders, so treat these figures as a planning baseline, not an offer.
Projected values are estimates and are not guaranteed. Actual results will vary.
How it works
How this annuity calculator works
Payout rate is not a return
Annuity income blends interest with the return of your own principal. A 7.9% payout rate on $200,000 doesn't mean the money earns 7.9%; it means the insurer hands back your premium plus credited interest, spread across the payout period. The calculator separates the two so you can see how much of the total is actually interest.
Break-even makes the trade visible
The break-even age is when cumulative payments exceed what you paid. Live past it and the annuity keeps paying anyway; that's the longevity insurance you bought. Die before it and the insurer keeps the difference, unless you paid extra for a refund or period-certain rider.
Lifetime payouts use a planning horizon
Insurers price lifetime annuities with mortality tables. This calculator approximates that by amortizing the purchase to your life expectancy input, extended for joint and survivor payouts since payments must cover the longer of two lives. Treat results as a planning baseline and get real quotes before deciding.
The comparison is the real decision
The question is rarely "is this annuity good?" but "is it better than keeping the money invested?" The comparison mode puts guaranteed income next to a withdrawal strategy: the annuity usually pays more per month, investing usually leaves more behind. Which matters more is a personal answer, not a math answer.

Know what you're buying
Fixed, variable, and indexed
Fixed
The insurer guarantees an interest rate and the payment schedule. Predictable, simple, and the easiest to compare across insurers. The trade is inflation: a level payment buys less every year, unless you pay extra for an increasing-payment rider.
Variable
Your premium is invested in market subaccounts, so value and income can rise or fall. This is where the 1% to 3% annual fee stacks live: mortality and expense charges, fund expenses, and rider costs. Read the prospectus before buying.
Indexed
Interest is credited based on an index like the S&P 500, subject to caps, participation rates, and floors. You give up part of the upside in exchange for downside protection. The crediting formulas are complex enough that regulators publish dedicated warnings about them.
Immediate vs deferred
Any of the three can start paying now (immediate) or grow first and pay later (deferred). Immediate annuities are bought with a single premium for income that starts within a month. Deferred annuities add a surrender-charge period while the money grows tax-deferred.
Tips
Factors to consider
Don't annuitize everything
A common approach is to build an income floor: Social Security plus pension plus annuity income covering essential expenses, with the rest of the portfolio staying invested for growth, flexibility, and heirs. Annuitized money is illiquid; keep enough outside for emergencies and large one-time costs.
Shop several insurers, same terms
Payout rates for identical terms vary meaningfully between insurers, and quotes move with interest rates. Get multiple quotes on the same day for the same premium, start age, and survivor option, and check the insurer's financial strength ratings while you're at it. State guaranty associations cap what's protected if an insurer fails.
Mind the inflation gap
A level $1,320 payment loses roughly a third of its buying power over 20 years at 2% inflation. Inflation-adjusted annuities exist but start with noticeably lower payments. Our inflation calculator shows what any fixed payment will really buy decades from now.
Compare against the lump-sum math
If you're weighing a pension's lump-sum offer against its monthly checks, that's the same decision this calculator's comparison mode models. Our pension calculator has a dedicated lump-sum-versus-monthly mode built for it.
