FD Calculator

How it's calculated

Maturity = P × (1 + r ÷ (100 × m))^{m × t}, where m is the number of compounding periods a year. Most banks compound FDs quarterly. Tax is estimated on the total interest at your slab rate.

How a fixed deposit grows

A fixed deposit (FD) pays interest at a rate fixed when you open it. Most banks compound the interest quarterly, which means interest is added to the balance every three months and then earns interest too. More frequent compounding gives a slightly higher yield.

With the example values, ₹5 lakh at 7% for 5 years with quarterly compounding matures at about ₹7,07,389. FD interest is taxable at your slab rate, so the calculator also shows the amount after tax, using the rate you enter.
