How it works
Enter your current savings, monthly contribution, expected annual return rate, years to retirement, and an optional inflation rate. The tool applies monthly compound interest to model growth and adjusts for inflation to show the real purchasing power of your projected balance. A year-by-year table shows balance, contributions, and interest earned. All calculation runs in your browser.
FV = PV × (1+r)^n + PMT × ((1+r)^n − 1) / r
Common use cases
- Seeing how much you will have at retirement given your current savings rate.
- Testing how starting earlier (or later) dramatically changes the final balance.
- Checking if you are on track to reach a retirement income goal.
Frequently asked questions
What return rate should I use?
A diversified stock portfolio has historically returned about 7% annually after inflation. Conservative estimates use 4-6%, aggressive 8-10%. These are long-term averages — actual returns vary year to year.
Does this include taxes?
No — the calculator models pre-tax growth. For after-tax estimates, reduce the return rate or apply your effective tax rate to the withdrawal amount separately.
