What is a Fixed Deposit (FD)?

A Fixed Deposit (FD) is a financial investment offered by banks and NBFCs where you invest a lump sum amount for a fixed tenure at a predetermined interest rate.

How is FD interest calculated?

FD interest is usually calculated using compound interest. This calculator uses quarterly compounding, which is the standard method followed by most Indian banks.

What is the maturity amount in FD?

The maturity amount is the total amount you receive at the end of the FD tenure. It includes your principal investment plus the interest earned.

Is FD interest taxable in India?

Yes. Interest earned on fixed deposits is fully taxable as per your income tax slab. Banks may also deduct TDS if interest exceeds the prescribed limit.

Can I withdraw FD before maturity?

Yes, premature withdrawal is allowed by most banks, but it may attract a penalty or reduced interest rate.

What is the safest FD tenure?

FD safety depends more on the bank or institution than tenure. Short to medium-term FDs (1–3 years) are commonly preferred during rising interest rate cycles.

Does compounding frequency matter?

Yes. Higher compounding frequency (quarterly vs annual) results in slightly higher maturity value over the same period.

How to Use the Fixed Deposit (FD) Calculator

Fixed Deposit or FD is one of the most widely used and reliable methods of investment for individuals in pursuit of fixed or predictable returns. It provides you with an option to invest a fixed amount of money for a certain period of time at an agreed or predetermined interest rate.

One area where market-related investments differ from fixed deposits is in the matter of certainty. When you make a market-related investment, you never know how much you are actually investing, how long you would be locking away the funds for, or how much you would get when the time is over.

The Fixed Deposit Calculator is created to assist you in calculating the maturity amount of your FD, the total interest earned on it, as well as the return on your investment. No more calculations using the compound interest rate formula or approximations on estimates. This calculator will provide you quick and accurate calculations on the methods followed by banks for FD calculations.

If it is used to compare tenures of FDs, compare interest rates, or plan savings in the future, you may get clarity and confidence before making an investment.

Enter the rate of charge applicable to your specific scheme FD.

3. Enter Time Period

You should now enter the number of years for the fixed deposit. This will determine the term after which your money will be invested.

Once all the amounts are entered, calculate the FD to know the value of the maturity and the total interest earned.

Look over your results to see what your investment will look like in terms of growth for different scenarios.

Key Formulas Used in the Calculator

FD Maturity Amount

A = P × (1 + r/n)^(n × t)

This compound interest formula calculates the maturity value of a fixed deposit. P = Principal investment amount r = Annual interest rate (decimal) n = Compounding frequency per year t = Time period in years

Interest Earned

Interest Earned = Maturity Amount − Principal

This represents the total interest gained over the FD tenure.
