About the Retirement Calculator

Retirement Calculator projects how retirement savings could grow between your current age and your planned retirement age, using only the figures you enter: current savings, a monthly contribution, an expected annual return, an optional yearly increase in contributions and an expected inflation rate. No rate is filled in for you, because every rate is your own assumption.

The method is shown in full. The annual return is divided by 12 and compounded monthly, each contribution is added at the end of the month, and the monthly contribution rises by your chosen percentage once a year, at the start of each new year. The results show the projected value at retirement, total contributions, estimated growth, the value in today’s purchasing power and a year-by-year table. Real returns, inflation, fees, taxes, withdrawals and lifespan cannot be predicted, and the tool does not judge whether any amount is enough.

Frequently asked questions

How is the projection calculated?

The annual return is divided by 12 to get a monthly rate. Each month the balance grows by that rate and the monthly contribution is added at the end of the month. In year 2 and later, the contribution is increased by your yearly increase percentage.

What does the inflation-adjusted value mean?

It divides the projected value by (1 + inflation rate) raised to the number of years. It shows roughly what the future amount could buy in today’s prices if inflation stayed exactly at the rate you entered.

Does this tell me whether I have saved enough?

No. How much someone needs depends on spending, health, family, other income, taxes and many other factors. The tool only projects the figures you enter.

Are the projected returns certain?

No. Returns, inflation, fees and taxes vary from year to year and cannot be predicted. Investments can also lose value. Treat the result as one possible illustration.

Are fees, taxes and withdrawals included?

No. The projection uses the return you enter as-is, with no fees, taxes or withdrawals. You can lower the return you enter to reflect expected costs.

Why are ages limited to whole years?

Whole years keep the year-by-year table clear. The retirement age must be greater than your current age and no more than 100.

Is my information saved or sent anywhere?

No. Every calculation runs in your browser. The numbers you enter and the results are not uploaded, not looked up online and not saved in browser storage. Reset clears them from the page.
