Fixed Deposit Calculator – Calculate FD Interest & Maturity Amount

A Fixed Deposit (FD) is one of the safest and most popular investment options in India and many other countries. It allows investors to earn guaranteed returns over a fixed tenure. This FD Calculator helps you calculate the maturity amount and total interest earned based on your investment amount, interest rate, tenure, and compounding frequency.

FD Formula

The compound interest formula used for FD calculation is:

A = P (1 + r/n)^(n × t)

  • P = Principal amount
  • r = Annual interest rate
  • n = Compounding frequency per year
  • t = Tenure in years
  • A = Maturity amount

Interest on fixed deposits is calculated using compound interest. Banks may compound interest annually, quarterly, monthly, or half-yearly. The more frequent the compounding, the higher the maturity value.
