🧮 Formula & Steps

1Periodic rate: r = 5.0% ÷ 12 = 0.4167% per period
2Number of periods: n = 20.00 yrs × 12 = 240 periods
3Payment formula (ordinary): PMT = PV × r(1+r)^n / [(1+r)^n − 1]
4Substituted: PV=$500,000.00, r=0.4167%, n=240, PMT=$3,299.78
5Result: PERIODIC PAYMENT = $3,299.78/mo

How Annuity Payouts Work

An annuity payout converts a lump sum into a stream of regular payments. Each period, interest is earned on the remaining balance, then a payment is made — early payments are mostly interest, and later payments draw down more principal, similar to a mortgage running in reverse. For the growth/accumulation side of an annuity before payouts begin, see our annuity calculator, and for a full retirement income picture pair this with our retirement calculator.

Annuity Payment Formula

Ordinary annuity payment: PMT = PV × [r(1+r)^n] / [(1+r)^n − 1]Annuity due payment: PMT_due = PMT_ordinary ÷ (1+r)Duration: n = −ln(1 − PV×r/PMT) ÷ ln(1+r)Balance needed: PV = PMT × [1 − (1+r)^−n] / r

PV = starting balance · r = periodic interest rate · n = number of payout periods · PMT = periodic payment.
