Formula steps

  1. Convert the annual rate into a rate for each payment period.
  2. Count total payments from years and payments each year.
  3. Estimate future value and present value for the fixed payment stream.
  4. Add one extra period of timing when annuity due is selected.

How to use the Annuity Calculator

  1. Enter the fixed payment made each period, such as $500 every month.
  2. Add the annual rate, number of years, and payments each year, such as 12 for monthly payments.
  3. Choose ordinary timing for end-of-period payments or annuity due for beginning-of-period payments.
  4. Calculate, then compare future value, present value, total payments, payment count, and timing before reading any real annuity contract.

Frequently asked questions

Plain-language answers about when to use the estimate, what your numbers mean, what is left out, and how privacy works.

When should I use the Annuity Calculator?

Use it when you want to test the exact inputs on this page: Estimate the future value of repeated monthly or yearly payments. Estimate what a fixed payment stream is worth today. The result is a check against your assumptions, not proof that a lender, tax app, broker, platform, or provider will use the same number.

What do the main Annuity Calculator inputs mean?

Payment amount means the fixed payment made each period, such as $500 each month or $6,000 each year. Annual rate means the fixed yearly rate assumption. Enter 5 for 5%, not 0.05. Time means how many years the payment stream lasts. Payments per year means how often payments happen. Use 12 for monthly payments and 1 for annual payments. Payment timing means whether payments happen at the end of each period, or at the beginning with one extra period to grow.

Is this the same as an annuity quote from an insurance company?

No. This page does the clean math for a fixed payment stream. A real annuity quote can change because of insurance pricing, fees, riders, surrender rules, guarantees, taxes, age, state rules, and contract wording.

What is the difference between ordinary annuity and annuity due?

An ordinary annuity treats each payment as happening at the end of the period. An annuity due treats each payment as happening at the beginning, so each payment gets one extra period in the formula.

Can this handle immediate or lifetime annuities?

Use it only as fixed-payment math. Immediate and lifetime annuities depend on contract pricing, life expectancy assumptions, payout choices, guarantees, and fees that are not in this calculator.

What is the Annuity Calculator doing with my numbers?

In plain language: The calculator converts the annual rate to a rate per payment period, counts the payments, then runs ordinary annuity or annuity-due formulas for future value and present value. $500 per month for 20 years creates 240 payments. At a 5% annual rate, the ordinary annuity estimate is about $205,516.83 future value and $75,762.66 present value.

How should I read the Annuity Calculator answer?

Future value is the estimated ending value of the payment stream. Present value is what that stream is worth today using the rate you entered. Total payments is only the money paid in, before interest math.

What does this estimate leave out?

This is fixed-payment math, not an insurance annuity quote. It does not include insurer pricing, mortality assumptions, fees, taxes, guarantees, riders, surrender charges, inflation adjustments, or contract terms. Read real annuity materials, fee tables, surrender rules, and tax notes before treating the answer as a retirement-income decision.

What should I double-check before copying the result?

Check payment timing, payments per year, and whether the payment is monthly or yearly. Then compare the math with real fees, surrender charges, guarantees, taxes, and contract terms before trusting it.

Why does payment frequency matter so much?

Frequency changes both the rate per period and the number of payments. Monthly payments over 20 years means 240 payments, while annual payments over 20 years means 20 payments.

Why should I check fees and surrender charges separately?

Fees and surrender charges can reduce real contract value. FINRA and Investor.gov both warn that annuities can be complex, so the math result should be checked against the actual contract.

Does the site save my finance inputs?

No. The calculator runs in your browser tab. Recent answers stay only on the page while you use it, and they are not sent to a server.
