The Fixed Deposit Calculator is a valuable tool for investors who want to determine the maturity amount of their fixed deposit investment. It helps you foresee the returns on your investment with precision. Here’s a breakdown of the variables involved:

Formula of Fixed Deposit Calculator

The calculator employs the following formula:

A = P(1 + (r/n))^(nt)


  • A stands for Maturity Amount, which is the total sum you’ll have at the end of your investment.
  • P represents the Principal Amount, i.e., the initial sum you invest.
  • r signifies the Annual Interest Rate, but it must be in decimal form (e.g., 5% as 0.05).
  • n denotes the Number of times the interest is compounded per year.
  • t stands for the Number of years the money is invested.

Using this formula, the Fixed Deposit Calculator can swiftly and accurately compute your maturity amount, taking the guesswork out of your financial planning.

General Terms: A Helpful Table

To make things even simpler, let’s provide a handy table of general terms that people frequently search for. This reference table can serve as a quick guide, saving you from performing manual calculations each time.

Principal Amount (P)Initial investment sum
