What is an FD Calculator?
An FD Calculator (Fixed Deposit Calculator) is a financial tool used to estimate the maturity amount and interest earned on a Fixed Deposit investment. By inputting the principal amount, interest rate, and tenure, it calculates exactly how much your money will grow over time using compound interest logic.
At Nexli Calculator, our tool helps investors plan their savings effectively. Whether you are saving for a short-term goal like a vacation or a long-term goal like retirement, this calculator shows you the guaranteed returns you can expect from your bank.

FD Calculation Formula
Fixed Deposits generally earn compound interest. The standard formula used by banks is as follows:
Maturity Amount
A = P × (1 + r/n)(n×t)
- A: Maturity Amount
- P: Principal Amount
- r: Annual Interest Rate (decimal)
- n: Compounding Frequency (usually 4 for quarterly)
- t: Tenure in Years
Total Interest
Finding the profit.
- Interest = Maturity Amount – Principal
- Example: If you invest $10k and get back $12k, your interest earned is $2,000.
