Free FD calculator — maturity value of a fixed deposit
Use this calculator to estimate what a fixed deposit (FD) could be worth when it matures. Enter the amount you deposit, the interest rate your bank offers, how long you will keep the deposit and how often the interest is compounded. You see the maturity amount, the interest earned and a year-by-year table. It covers the common cumulative FD, where the interest is added back to the deposit and paid out at the end.
How to use the FD calculator
- Enter the deposit amount in rupees.
- Enter the annual interest rate your bank quotes.
- Enter the tenure in years and months.
- Pick the compounding. Many Indian banks compound FD interest quarterly, but check the terms of your own deposit.
- Click Calculate.
The formula
Maturity amount A = P × (1 + r ÷ n)n × t, where P is the deposit, r is the annual rate as a decimal, n is the number of times interest is compounded each year and t is the tenure in years. The interest earned is A − P. Choosing "At maturity" gives simple interest: A = P × (1 + r × t).
Worked example
A deposit of ₹1,00,000 at 7% a year for 5 years, compounded quarterly, grows to about ₹1,41,478, so the interest is about ₹41,478. With yearly compounding the same deposit gives about ₹1,40,255. With monthly compounding it gives about ₹1,41,763. The more often interest is compounded, the higher the maturity amount, but the difference is small over short tenures.
What this calculator does not include
- Tax. Interest on an FD is taxable, and banks may deduct TDS. This tool shows the interest before any tax.
- Premature withdrawal. Breaking an FD early usually earns a lower rate and may carry a penalty.
- Bank rules. Banks differ in how they count days and round the interest, so your receipt may differ by a small amount.
- Interest payout options. It does not model monthly or quarterly payout FDs, where the interest is paid out instead of added to the deposit.
