How are future savings estimated?

The starting balance and each deposit earn interest at the given rate, compounded at the deposit frequency, and are added together.

Is the interest rate guaranteed?

Savings growth calculation

The starting balance and each regular deposit earn interest over the periods that remain before the end date.

Future savings = grown starting balance + future value of deposits

Balance: Money already saved
Deposit: Amount added each period
Rate: Annual interest rate

Worked example

$5,000 plus $200 monthly at 4% for 5 years grows to about $19,365, including about $2,365 interest.

About the Savings Calculator

The Savings Calculator estimates how a balance grows over time when you add regular deposits and earn interest.

It compounds your balance at the deposit frequency using the interest rate, then separates the total you deposited from the interest earned.

This is an estimate based on a constant rate. Real savings rates change, and all calculations run in your browser.
