The time period during which an annuity is being “built up” is called the accumulation phase and the calculator for doing those computations is located here.

When you retire and you start receiving payouts, the annuity has entered its annuitization phase and the computations for that phase can be done on this page.

There are several ways in which an annuity may be paid out, the most common of which is the systematic withdrawal schedule. Under this payout system, the principal continues to earn interest until the balance reaches zero. You (or whoever is in charge of your annuity) compute the annual (or monthly) payment you will receive. Most importantly, you must decide how long the annuity payments are to continue because you don’t want to “outlive” the annuity.

The annuity payout calculator allows you the option of solving for any of 4 variables.
