Fixed Deposit (FD) Calculator – A Comprehensive Guide

A Fixed Deposit (FD) Calculator is a financial tool that helps individuals and businesses calculate the maturity amount of a fixed deposit investment. It provides an estimate of the interest earned over a specified tenure based on the deposit amount, interest rate, and compounding frequency.

1. What is a Fixed Deposit (FD)?

A Fixed Deposit (FD) is a savings scheme offered by banks and financial institutions where an individual deposits a lump sum amount for a fixed period at a predetermined interest rate. The principal amount earns interest over the chosen tenure, and at maturity, the depositor receives the total amount (principal + interest).

2. How Does an FD Calculator Work?

The FD calculator works based on the following formula:

A = P \times \left(1 + \frac{r}{n} \right)^{n \times t}

Where:

A = Maturity Amount

P = Principal (Initial Deposit)

r = Annual Interest Rate (in decimal)

n = Number of times interest is compounded per year

t = Tenure in years

Example Calculation:
If you invest ₹50,000 in an FD for 5 years at an interest rate of 6% per annum, compounded quarterly, the maturity amount will be:

A = 50,000 \times \left(1 + \frac{6}{4 \times 100} \right)^{4 \times 5}

After calculation, the maturity amount will be ₹67,148 approximately.
