Annuity Payout Calculator by TheCalcTools

How the Annuity Payout Calculator works

Enter the lump sum, an assumed interest rate and the number of years you want payments to last.

The payment is the level amount that uses up the balance exactly at the end.

This is the same formula used for loan payments.

The formula

payment = PV × r ÷ (1 − (1 + r)^−n)

Worked example

Using the default values shown in the calculator:

Lump sum$300000
Annual interest rate (%)4 %
Payout period (years)25
  1. Monthly rate = 4% ÷ 12; 300 payments.
  2. Monthly payout = $1,583.51.
  3. Total paid out is $475,053, including $175,053 of interest.

Result:

Monthly payout$1,583.51
Total paid out$475,053
Interest earned along the way$175,053

Frequently asked questions

Is this the same as a commercial annuity?

No. Insurers’ annuities depend on their pricing, life expectancy and fees, and may pay for life. This is a fixed-period illustration.

What if inflation rises?

The payment is fixed in dollars, so its buying power falls over time.
