Calculate your fixed deposit (FD) maturity amount in seconds using the FD Calculator!

What Exactly is an FD?

An FD is pretty straightforward. You hand over a specific lumpsum amount or SIPs to a bank or NBFC, lock it in for a specific timeframe, and they pay you a fixed interest rate. There's no stock market drama here. Your capital stays protected, which is exactly why conservative investors rely on these accounts for safe parking.

The Math Behind Your Returns

Banks calculate your returns using compound interest, meaning you earn interest on your interest. The standard formula they run in the background is A = P(1 + r/n)^(nt). Without getting bogged down in algebra, this basically factors in your starting principal, the annual rate, how often the bank compounds it (usually quarterly), and your total time in years. Our tool does this math instantly, so you never have to touch a spreadsheet.

Picking Your Payout Style

You’ll have to choose how you want your money back when opening the account. With a cumulative FD, the bank reinvests your interest and provides a lumpsum amount at the very end. It gives you the full power of compounding.

On the flip side, a non-cumulative FD pays you out regularly, like monthly or quarterly. It’s perfect if you require a steady cash flow, though your final maturity amount won't be as high since the interest isn't compounding.

The Senior Citizen Advantage

If you're over 60, banks automatically give you a better deal. They usually tack on an extra 0.25% to 0.50% to the standard rate, which actually makes a solid difference for retirees trying to build a reliable monthly income.
