Savings Interest Calculator
Compound interest on FD, RD or savings deposits with your choice of compounding frequency.
About the Savings Interest Calculator
Savings Interest Calculator computes the maturity value of any fixed deposit, recurring deposit or savings account using the standard compound-interest formula A = P × (1 + r/n)nt. Choose how often interest is compounded — annually, half-yearly, quarterly, monthly or daily — to match what your bank actually does. Optionally add a fixed monthly contribution and the tool treats it as a separate compounding annuity stacked on top of the base principal. The output shows the maturity value, the total amount contributed and the interest earned, so you can see at a glance how much your money has grown by.

Pro tip
Quarterly compounding is the default for most Indian FDs. Banks occasionally advertise an "effective annual yield" — use that figure as the annual rate to skip the math.
