What is an FD Calculator

A Fixed Deposit Calculator estimates the maturity amount and interest earned on a lump-sum deposit held for a fixed tenure at a fixed rate, using compound interest.

Formula

FD Maturity Formula

Maturity Amount = P × (1 + r/n)^(n × t)

P = principal amount
r = annual interest rate (decimal)
n = compounding periods per year · t = years
