How it works

A fixed-period annuity converts a lump sum into level monthly payments that exactly exhaust the balance over the chosen term while the remainder keeps earning interest. This uses the same amortization math as a loan, run in reverse to pay you.

Frequently asked questions

Is this a lifetime annuity?

No — it models a fixed number of years, after which the balance is gone. A true lifetime annuity from an insurer pays until death and prices in mortality, which this calculator does not.
