Solution

  2. Enter the number of Years and your Compounding frequency.
  3. Choose whether payments happen at the start or end of each period.
  4. Read the Future Value, Total Paid In, and Total Interest Earned.

What this calculator does

An annuity is a series of equal payments made at regular intervals. This calculator projects the future value of that entire payment series, compounded at your chosen rate and frequency, showing both the total amount you’ll have contributed and how much of the final balance came purely from interest.

FV = PMT × [((1 + r/n)^(nt) − 1) / (r/n)]

Ordinary annuity vs annuity due

An “ordinary annuity” pays at the end of each period, while an “annuity due” pays at the start. The annuity due version produces a higher future value because each payment gets one additional compounding period to grow, this calculator’s timing toggle lets you model either convention depending on how your specific payment plan actually works.

Frequently asked questions

What’s the difference between an ordinary annuity and an annuity due?

An ordinary annuity pays at the end of each period, while an annuity due pays at the start, the annuity due produces a higher future value since each payment gets one extra period to compound.

How much of my final balance comes from interest versus my own contributions?

This calculator separates Total Paid In (your actual contributions) from Total Interest Earned, so you can see exactly how much of the final future value is growth versus your own money.
