FD Calculator | Next TechLabs

About the FD Calculator

A fixed deposit (FD) calculator estimates the maturity value of a lump sum invested for a fixed term at a fixed interest rate. Because FD interest is usually compounded periodically, the final amount is more than simple interest would suggest, and seeing the projection helps you compare offers.

Enter your principal, the interest rate, and the tenure to see the estimated interest earned and the maturity amount. The result is an estimate — your bank’s exact compounding frequency and any applicable tax on interest will affect the amount you actually receive.

Frequently Asked Questions

How is FD interest calculated?

Most banks compound FD interest quarterly. Compounding means each period’s interest is added to the principal, so later interest is earned on a larger base than with simple interest.

Is the maturity amount guaranteed?

The rate is fixed at booking, so the projection is reliable, but the actual payout depends on the bank’s exact compounding frequency and any tax deducted on the interest earned.

Is FD interest taxable?

In many countries interest income is taxable and may have tax withheld at source. This calculator shows pre-tax figures; check your local rules for the net amount.
