🪙 FD Calculator

Find your fixed deposit maturity value, interest earned and effective yield.

What is an FD? A fixed deposit (FD) locks a lump sum with a bank for a fixed tenure at a guaranteed interest rate. Interest compounds periodically, so the maturity value is more than just rate × years — this calculator applies the exact compounding math.

How to Use the FD Calculator

Fixed deposits are the default safe investment across South Asia and the Gulf: guaranteed returns, no market risk. Enter the amount you plan to deposit, the annual rate your bank is actually offering (don't guess — check your bank's FD rate card), the tenure in years, and the compounding frequency — then press Calculate Maturity.

The insight most people miss: compounding frequency moves the needle. Quarterly compounding (the Indian bank standard) beats yearly compounding on the same rate, and stretching tenure from 5 to 10 years more than doubles the interest thanks to compounding on compounding. The effective annual yield row shows what the rate really earns you after compounding — a 7% nominal rate compounded quarterly is about 7.19% in real terms.

The year-by-year table also reveals why premature withdrawal hurts: interest accelerates later, so breaking an FD early forfeits the richest years. Banks also typically cut about 0.5–1% for early exit. Compare a few tenure options before you book.

A reality check: the maturity value shown is pre-tax — FD interest is generally added to your income and taxed at your slab rate. And remember a locked rate is a double-edged sword: your 7% is safe if rates fall, but stuck if rates rise.

Frequently Asked Questions

What is the FD maturity value formula?

A = P(1 + r/n)^(n*t), where P = deposit amount, r = annual rate (decimal), n = compounding frequency per year, t = tenure in years. Interest earned = A - P.

How does compounding frequency affect an FD?

More frequent compounding (quarterly vs yearly) adds interest to the principal more often, so the maturity value is slightly higher. Most Indian banks compound FD interest quarterly.

Can my FD interest rate change during the tenure?

No. Once you book an FD, the rate is locked for the full tenure even if banks later raise or cut rates. A new deposit always earns the rate prevailing on the booking date.

What happens on premature FD withdrawal?

Most banks allow early withdrawal but charge a penalty — usually around 0.5% to 1% lower interest than the rate for the completed period. Check your bank's terms before breaking an FD.

Is FD interest taxable?

Generally yes — FD interest is added to your income and taxed at your slab rate, and banks deduct TDS above a threshold. This calculator shows pre-tax maturity; check your local tax rules for the after-tax figure.
