What is an FD Calculator?

An FD Calculator is an online tool that helps you estimate the maturity amount and interest earned on a fixed deposit. Enter the principal, annual interest rate, and tenure, and the calculator instantly returns the maturity value and total interest earned. It works for both cumulative and non-cumulative FDs, helping you compare returns before committing your money.

How to Use FD Calculator – 3 Step Flow

Streamline your finances with an easy, automated process — calculate, plan, and achieve your financial goals.

1STEP

Enter your deposit details

Input the principal amount you plan to deposit, the annual interest rate offered by your bank or NBFC, and the FD tenure in months or years. For senior citizen FD rates, use the rate your institution has quoted, as these are typically 0.25%–0.50% higher than regular rates.

2STEP

Select the interest payout type

Choose between cumulative (interest compounded and paid at maturity) or non-cumulative (interest paid out monthly, quarterly, or annually). Cumulative FDs give a higher maturity value due to compounding, while non-cumulative FDs suit those who need regular income.

3STEP

Review your result

The calculator instantly shows the maturity amount, total interest earned, and the effective return on your investment. Adjust the tenure or principal to compare different scenarios before you decide.

How is Fixed Deposit Maturity Calculated?

For Cumulative (compounding) FDs: A = P × (1 + r/n)^(n × t) Where: A = Maturity amount P = Principal deposit amount r = Annual interest rate (in decimal) n = Number of compounding periods per year (typically 4 for quarterly) t = Tenure in years Total Interest Earned = A − P

Frequently Asked Questions

An FD Calculator is an online tool that calculates the maturity amount and interest earned on a fixed deposit based on the principal, interest rate, and tenure you enter. It helps you estimate returns before opening an FD, without needing to do the calculation manually.

In a cumulative FD, interest is compounded and paid out at maturity along with the principal, resulting in a higher final amount. In a non-cumulative FD, interest is paid out at regular intervals, monthly, quarterly, or annually, making it suitable for those who need periodic income.

Most Indian banks compound FD interest quarterly, so the calculator uses the compound interest formula by default. For non-cumulative FDs with periodic payouts, simple interest applies since interest is not reinvested.

Yes. Interest earned on fixed deposits is added to your total income and taxed as per your applicable income tax slab. Banks deduct TDS at 10% if annual FD interest exceeds ₹40,000 (₹50,000 for senior citizens). The calculator does not factor in taxes.

Yes. Simply enter the interest rate applicable to senior citizens, typically 0.25% to 0.50% higher than regular rates, and the calculator will return the accurate maturity amount and interest for that rate.

The calculator gives a reliable estimate based on the inputs you provide and standard quarterly compounding. The actual maturity amount from your bank may differ slightly due to rounding conventions, specific compounding methods, or TDS deductions applied at source.
