FD Calculator (Fixed Deposit Maturity Value Calculator)
A fixed deposit is one of the safest ways to grow savings in India, offering a guaranteed return over a chosen term. But the headline interest rate alone does not tell you what you will actually receive at maturity — how often interest is compounded matters too. This FD maturity value calculator does the full maths for you. Enter your principal amount (the investment amount you deposit), the interest rate, the tenure, and how often interest is compounded, and it instantly shows the maturity value, the interest earned, and the total amount you receive. Most Indian banks — from the State Bank of India to Bank of India — compound interest quarterly, which earns slightly more than simple interest or annual compounding at the same rate. Use this maturity value calculator to compare bank interest rates side by side, see how a higher rate changes your maturity amount and interest, and set realistic expectations before you lock in your money. Remember that FD interest is added to your income and taxed under the Income Tax Act, so your post-tax return can be lower than the headline figure.

About the FD Calculator
An FD calculator — also called a fixed deposit maturity value calculator — estimates the maturity amount of a fixed deposit by applying the compound interest formula at your bank’s compounding frequency. Interest is calculated on your principal amount and then added back to the balance, so each period earns interest on a slightly larger sum. The tool separates your investment amount from the interest earned, so you can see the true return and the total amount payable at maturity.
Why it is useful
Banks quote an annual rate, but the compounding frequency and tenure change the final amount. This maturity value calculator lets you compare deposits and bank interest rates accurately, decide between a cumulative FD and a payout option, and plan goals that rely on a guaranteed sum at a known date.
How the calculation works
For a cumulative FD, the maturity value is A = P × (1 + r/n)^(n × t), where P is the principal, r is the annual rate, n is the number of times interest compounds per year (4 for quarterly), and t is the tenure in years. The interest earned is simply A minus P.
Key inputs explained
- Deposit amount: The principal you place in the FD.
- Interest rate: The annual rate offered by the bank.
- Tenure & compounding: The deposit term and how often interest compounds (usually quarterly).
Example calculation
Inputs
- Principal
- ₹2,00,000
- Interest rate
- 7% p.a.
- Tenure / compounding
- 5 years / quarterly
Calculation breakdown
- Rate per quarter
- 7 ÷ 4 = 1.75%
- Number of quarters
- 5 × 4 = 20
- A formula
- 2,00,000 × (1.0175)^20
Your ₹2 lakh grows by about ₹82,786 over five years. Quarterly compounding earns a little more than annual compounding at the same 7% rate, which is why frequency matters.
