FD Calculator

A fixed deposit (FD) pays a fixed interest rate on a lump sum for a fixed period. Many banks compound the interest every quarter, which means interest is added to the balance four times a year and then earns interest itself.

Frequently asked questions

How is FD maturity amount calculated?

Maturity amount = P × (1 + r ÷ n)ⁿᵗ. P is the deposit, r the annual rate as a decimal, n the compounding periods per year and t the years.

Does quarterly compounding give more than yearly?

Yes, slightly. More frequent compounding adds interest to the balance sooner, so the maturity amount is a little higher at the same stated rate.

Is FD interest taxable?

Interest from a fixed deposit is generally taxable as income. Check the current rules or ask a tax professional.

Does the result include TDS?

No. The result is before any tax deducted at source.
