Fixed Deposit Calculator – Understand FD Returns Easily
A Fixed Deposit (FD) is a popular term investment option offered by banks and NBFCs in India. In an FD, a lump sum amount is invested for a fixed tenure at a predetermined interest rate. The deposited amount remains locked until maturity, making it a low-risk and predictable investment choice.
A Fixed Deposit Calculator helps you estimate the maturity value and total interest earned on your investment without performing complex manual calculations.
How Does an FD Calculator Work?
An FD calculator uses standard interest formulas to calculate the maturity amount based on the deposit amount, interest rate, tenure, and compounding frequency. Most bank FDs in India follow compound interest, usually compounded quarterly.
Fixed Deposit Maturity Formula
The maturity value of a compound interest Fixed Deposit is calculated using the formula below:
M = P × (1 + r / n)n × t
Where:
- P = Principal (Deposit Amount)
- r = Annual Rate of Interest
- t = Investment Tenure (in years)
- n = Number of times interest is compounded in a year
- M = Maturity Value
The total interest earned is calculated by subtracting the principal amount from the maturity value.
Total Interest = M − P
Types of Fixed Deposits
- Simple Interest FD: Interest is calculated only on the principal amount.
- Compound Interest FD: Interest is calculated on the principal as well as previously earned interest.
Most modern Fixed Deposits use compound interest, which results in higher returns over longer durations due to the power of compounding.
