What is an FD Calculator?

A Fixed Deposit (FD) Calculator is an online tool that helps investors estimate the maturity amount of their fixed deposit. It calculates returns based on the deposit amount, tenure, and interest rate, making financial planning easier and more accurate.

How Does the FD Calculator Work?

The best FD calculator uses either simple interest or compound interest based on the type of deposit:

1. Simple Interest Formula:

A = P × r × t / 100

Where: A = Interest Amount P = Principal (Initial Deposit) r = Annual Interest Rate (%) t = Tenure (in years)

2. Compound Interest Formula:

A = P × (1 + r/n)^(n×t)

Where: A = Maturity Amount P = Principal (Initial Deposit) r = Annual Interest Rate (in decimal) n = Number of compounding periods per year t = Tenure (in years)

For quarterly compounding, n = 4; for monthly, n = 12.
