Annuity Rate of Return Calculator

When an annuity offers you a stream of payments today, the salesperson rarely states the actual return. This calculator solves for the implied annual rate of return, known as the Internal Rate of Return (IRR), so you can compare the annuity on equal footing with CDs, Treasury bonds, or any other fixed-income alternative.

To see how compounding builds a balance step by step, independent of any specific annuity, try our compound interest calculator.

How does this calculator work?

Start by entering the initial investment, or the lump sum you pay today, along with the annual payment you expect to receive and the length of the annuity in years. The calculator uses those three figures to find the discount rate that makes the present value of all future payments equal to what you paid up front. That rate is your true annualized return.

The Final Value of Annuity field adds one more dimension. It represents the lump sum you would receive if you surrendered or cashed out the annuity in a given year, such as a surrender value, death benefit, or maturity payout. When you enter an amount, it populates every row in the data table. Each row then calculates the rate of return as if you exited that year, receiving that year's payment plus the final value as proceeds. Prior years carry only the plain annual payment in the calculation.

You can override individual cells in the table to model a surrender value schedule that changes year by year. The headline rate at the top always reflects the full-term return, or holding the annuity to maturity.

How the data table works

Each row in the table answers a specific question: what annualized return would you have earned if you exited the annuity at the end of that year? The rate generally rises as the annuity matures, because the upfront cost is spread across more years of payments. Comparing early-year rates against the full-term rate shows exactly how much yield you give up by surrendering early.

Worked example

Pay $200,000 today for an annuity that pays $15,000 per year for 30 years, with a $50,000 final value.

Initial investment

$200,000

Annual payment

$15,000 × 30 yrs

Final value

$50,000

Total received

$500,000

Full-term rate of return

~6.9%

How the numbers work

The calculator finds the rate r that satisfies: $200,000 = $15,000÷(1+r)¹ + $15,000÷(1+r)² + … + ($15,000 + $50,000)÷(1+r)³⁰. Without the final value this annuity returns roughly 6.6%. Adding the $50,000 surrender value pushes it to about 6.9%. This is a modest but real improvement that reflects the residual value of the contract.

The $15,000 annual payment looks like a 7.5% yield on the $200,000 investment, but because payments trickle in over 30 years rather than arriving today, the true annualized return is lower. That is the number to compare against a 30-year Treasury or CD. If safe alternatives yield more, the annuity isn't fairly compensating you for its reduced liquidity.
