How to use the Annuity Calculator

The Annuity Calculator is free and runs entirely in your browser — no sign-up, and nothing you enter leaves your device. It opens pre-filled with a realistic example, so you can see how it works before replacing any figure with your own; the results update as you type. Press Calculate to refresh the result panel, or Reset to return to the example.

The inputs it asks for:

  • Solve For — choose one — Future Value, Required Payment.
  • Periodic Payment — a dollar amount.
  • Target Future Value — a dollar amount.
  • Annual Interest Rate — a percentage (enter 6 for 6%).
  • Years — a number.
  • Annuity Type — choose one — Ordinary (End of Period), Annuity Due (Beginning).

Worked example

Using the example values — Solve For Future Value, Periodic Payment $500.00, Target Future Value $0.00, Annual Interest Rate 6%, Years 10, Annuity Type Ordinary (End of Period) — the Annuity Calculator returns a Future Value of $81,939.67. It also reports Total Contributions ($60,000.00), Interest Earned ($21,939.67).
