Estimate the maturity value and interest on a fixed deposit from the amount, rate, tenure and compounding frequency you choose.
Quick answer: A fixed deposit grows by compounding: maturity = P × (1 + r ÷ m)^(m × t). ₹1,00,000 at 7% a year for 5 years with quarterly compounding matures at about ₹1,41,478, which is ₹41,478 of interest.

Maturity amount = P × (1 + r ÷ m)^(m × t), where P is the deposit, r is the annual rate as a decimal, m is how many times a year interest is compounded (1, 2, 4 or 12) and t is the number of years. Interest earned is the maturity amount minus the deposit.
Banks often compound FD interest quarterly, but practice differs by bank and scheme, so pick the compounding that matches your deposit receipt.
| Deposit | ₹1,00,000 |
|---|---|
| Rate | 7% a year |
| Tenure | 5 years |
| Compounding | Quarterly (4 times a year) |
| Maturity amount | ₹1,41,478 |
| Interest earned | ₹41,478 |
With yearly compounding the same deposit matures at about ₹1,40,255.
More frequent compounding adds a little. On ₹1,00,000 at 7% for 5 years, yearly compounding gives about ₹1,40,255 and quarterly compounding gives about ₹1,41,478. The rate and the tenure matter far more than the compounding frequency.
Check the bank's current rate card for your tenure, whether interest is paid out or added to the deposit, and the penalty for breaking it early. Interest on deposits is taxable and tax may be deducted at source, so confirm the current rules for your situation with the bank or a tax professional.
Bank deposits are insured by DICGC up to ₹5 lakh per depositor per bank, covering principal and interest together. The limit applies separately to each bank.

Use the compounding frequency and rate published for the specific deposit product. Important note: Actual maturity can differ because of bank rules, taxation, premature withdrawal terms and product-specific compounding.
Use maturity = P × (1 + r ÷ m)^(m × t), then subtract the deposit. Or enter the amount, rate, tenure and compounding in the calculator above.
It depends on the scheme. A cumulative deposit compounds and pays everything at maturity, which is what this calculator shows. A payout deposit pays interest out regularly instead.
Bank deposits are insured by DICGC up to ₹5 lakh per depositor per bank, including principal and interest. Amounts above that are not covered, and the limit applies separately to each bank.
No. Interest is taxable and tax may be deducted at source, so your return after tax will be lower. Check the current rules for your situation.
