FD Calculator
See what your fixed deposit will be worth at maturity and exactly how much interest it earns.
How an FD grows
A fixed deposit pays a fixed interest rate. The bank usually adds the interest back every quarter, so the next quarter's interest is calculated on a bigger balance. More frequent compounding—like monthly instead of yearly—makes the final amount slightly higher at the same rate.
Banks quote the rate per year. Pick the frequency that matches your FD's terms. Senior citizens sometimes get a slightly better rate, so use the rate that applies to you. For investments that grow with the market instead of a fixed rate, check our investment calculators.
Common questions
How is interest added to an FD?
Most banks add interest every quarter: the interest is added to your balance, and then the next quarter's interest is calculated on that larger amount. Adding interest more frequently gives you a bit more in the end.
Do I pay tax on FD interest?
Yes. The interest counts as income and is taxed based on your tax slab. Banks deduct TDS if the annual interest crosses a threshold. This calculator shows the amount before tax—set aside money for taxes when you withdraw.
What happens if I withdraw before maturity?
Early withdrawal usually means a lower interest rate and a small penalty, so you get less than what's shown here. Check your bank's specific terms and penalty before withdrawing early.
