FD Calculator
Estimate the maturity amount and total interest earned on your fixed deposit investment.
What Is an FD Calculator
A fixed deposit calculator helps you estimate how much your deposit will grow by the end of the investment period. It calculates the maturity amount based on your principal, the bank's annual interest rate, the investment tenure, and the compounding frequency.
FD Maturity Formula
The formula used to calculate FD maturity is:
M = P × (1 + r/n)n × t
Where:
- M = Maturity amount
- P = Principal (deposit amount)
- r = Annual interest rate (in decimal, e.g. 0.075 for 7.5%)
- n = Number of times interest is compounded per year (e.g. 4 for quarterly)
- t = Tenure in years
How to Use the Calculator
Enter your deposit amount, the annual interest rate offered by your bank, the tenure in years, and the compounding frequency. Click Calculate to see the maturity amount and interest earned.
Example Calculation
If you deposit 1,00,000 at 7.5% per annum for 3 years with quarterly compounding (n=4), the maturity amount is approximately 1,25,088 and the interest earned is 25,088.
Benefits of FD Investment
