FD Calculator
An FD Calculator helps you determine the maturity amount and interest earned on a fixed deposit over a given tenure, based on the principal amount, interest rate, and compounding frequency.
Compound Interest Formula (most commonly used by banks):

Where:
- A = Maturity Amount
- P = Principal (Initial Deposit)
- r = Annual Interest Rate (in decimal)
- n = Number of compounding periods per year
- t = Time (in years)
Interest Earned = A – P
Example:
Aman has a FD of ₹1,00,000 for 3 years at 6% rate of interest and n that bank the compounding frequency is quarterly so the maturity amount earned is ₹119556 after that total interest earned is
Interest Earned = 119556 – 100000 = ₹19,556
