How to use Annuity Calculator

Provide the recurring deposit plan, and the calculator will estimate how those equal payments may accumulate over the selected time period.

What this calculator is for

This calculator is for savings plans built on repeated equal contributions, such as monthly investing or sinking funds. It is useful when the question is about the value of the payment stream itself rather than a lump sum alone.

Tips

  • Beginning-of-period payments build a slightly larger result than end-of-period payments, so choose the timing that matches reality.
  • If deposits are not truly level over time, treat the result as a simplified benchmark rather than an exact projection.
