How This Annuity Calculator Works
An annuity payout converts a lump sum into regular, predictable payments over a set period. Each payment includes a portion of your principal plus the interest it earns along the way.
Here’s what we’ll show you:
- Your Fixed Payment Amount — know exactly what you’ll receive each period
- Total Payments Received — the full sum you’ll collect over the term
- Total Interest Earned — how much of your payout comes from investment growth
- Number of Payments — exactly how many checks you’ll get
The Math Behind It (Made Simple)
Your Payment = Principal × Rate ÷ [1 − (1 + Rate)^(-Total Payments)]
Here’s what each part means:
- Principal — your initial lump sum
- Rate — your interest rate per payment period (annual rate ÷ payments per year)
- Total Payments — number of payments over the entire term
Think of it like this: your money earns interest, and that interest is spread evenly across all your payments—giving you a steady, predictable income.

Common Questions About Annuity Payouts
What exactly is an annuity payout?
It’s a fixed, periodic payment you receive from a lump sum you’ve invested in an annuity. Each payment includes both a return of your original principal and the interest it’s earned.
How is my annuity payment calculated?
Your payment is calculated using a formula that spreads your principal plus earned interest evenly across all your payments over the chosen term—giving you a predictable income stream.
What’s the difference between a period-certain and lifetime annuity?
- Period-certain — pays for a fixed number of years, whether you’re alive or not.
- Lifetime annuity — pays as long as you live. The payment amount depends on your life expectancy and is calculated differently.
This calculator estimates a period-certain payout. Lifetime payments vary by provider and are based on actuarial tables.
Are my annuity payments taxable?
It depends on how the annuity was funded:
- Non-qualified annuities (after-tax dollars) — a portion of each payment is a tax-free return of principal; the interest portion is taxed as ordinary income.
- Qualified annuities (pre-tax dollars, like an IRA rollover) — generally fully taxable as ordinary income.
Always consult a tax professional for your specific situation.
📌 Note: This calculator estimates a fixed period-certain payout. Lifetime annuity payments depend on actuarial life expectancy factors and will vary by provider. Always confirm details with your annuity provider or financial advisor before making decisions.
