What is a savings calculator?

A savings calculator projects the future value of your savings when you start with an initial deposit and add a fixed amount every month, with interest compounding monthly.

How it's calculated

Future value = initial × (1 + i)^N + monthly × ((1 + i)^N − 1) ÷ i, where i is the monthly rate (annual rate ÷ 12 ÷ 100) and N is the number of months (years × 12). For 0% interest it is simply initial + monthly × N. Interest earned = future value − total contributed.

Example

Starting with 1 000 and adding 200 a month at 6% for 10 years grows to 34 595.27. Of that, 25 000 is your own contributions and 9 595.27 is interest.
