How to see your savings grow

  1. Type what you have now, and how much you add each month.
  2. Type the expected yearly return and the number of years.
  3. Choose how often profit is added. Most savings accounts and funds are monthly or quarterly.

Why compounding matters

Profit is added to your balance and then earns profit itself. Over long periods this makes a big difference: the last years usually add much more than the first.

Does this include inflation or tax?

No. To see the value in today’s money, take the inflation rate off the return, for example 12% return with 7% inflation is roughly 5%.

Is anything I type saved?

No. The numbers are worked out in your browser and are not sent anywhere.
