Annuity Payout Calculator

Estimate the payment you can withdraw from an annuity balance over a fixed term, using an interest rate and payment schedule.

How to Use

  1. Enter your starting balance (the annuity value you’ll draw from).
  2. Enter the annual interest rate (nominal APR) and choose compounding/payment frequency.
  3. Set the term (years + optional months).
  4. Select whether payouts happen at the end or beginning of each period.
  5. View results and open Show Work for the exact formula steps.

Annuity Payout Formulas

This tool solves the payment amount from a present value (starting balance).

  • Periodic rate: r = APR / paymentsPerYear
  • Total payments: N = termYears × paymentsPerYear (+ months adjustment)
  • Ordinary annuity (end of period): PMT = PV × r / (1 − (1 + r)^(-N))
  • Annuity due (beginning of period): PMT_due = PMT × (1 + r)
Where PV = starting balance, PMT = periodic payout, r = periodic interest rate, N = number of payments.

FAQ

What’s the difference between ordinary annuity and annuity due?

Ordinary annuity pays at the end of each period. Annuity due pays at the beginning. Beginning-of-period payments are typically larger because funds are withdrawn sooner.

Is this “guaranteed” for real annuities?

This is a math model using a fixed rate. Real products can include fees, rider rules, variable returns, and insurer-specific terms. Use this as a planning estimate.

What if the interest rate is 0%?

Then payouts are simple: PMT = PV / N.

Does changing payment frequency change the result?

Yes. With the same APR and term, changing how often you withdraw changes the periodic rate and number of periods, which affects PMT.
