FD Calculator

How the FD calculator works

A fixed deposit (FD) lets you lock away a lump sum with a bank or NBFC for a fixed tenure at a guaranteed interest rate. Unlike market-linked investments, your return is fixed the day you open the deposit — which makes an FD one of the safest ways to grow money in India. This calculator models a cumulative FD, where the interest is reinvested every quarter and paid out in a single lump sum at maturity.

Enter your deposit amount, the annual interest rate your bank offers and the tenure to see your maturity value, split between the principal you invested and the interest you earned. Because interest is compounded quarterly — added to your balance every three months so it too starts earning interest — the effective yield is slightly higher than the headline rate, and the longer you stay invested the more that compounding adds up. The figures shown are pre-tax; FD interest is taxable at your income-tax slab, so your net return will be a little lower.
