FD Calculator (India)
Estimate the maturity value and interest on a fixed deposit. Enter your principal, the interest rate, the tenure and how often interest compounds.
A fixed deposit locks a lump sum with a bank for a set period at a guaranteed interest rate. Because the interest compounds — usually quarterly in India — your money grows a little faster than simple interest would suggest. This calculator works out the maturity amount and the interest you'll earn from your principal, rate, tenure and compounding frequency, so you can compare deposits before you commit.
How FD maturity is calculated
The maturity is the principal grown by compound interest over the tenure, using the compounding frequency you choose.
where P = principal, r = annual rate, n = times compounded per year, t = years
| ₹1,00,000 at 6.5% (quarterly) | Maturity |
|---|---|
| 1 year | ₹1,06,660 |
| 3 years | ₹1,21,341 |
| 5 years | ₹1,38,042 |
Worked example
₹1,00,000 at 6.5% for 5 years, compounded quarterly:
| Rate per quarter = 6.5% ÷ 4 | 1.625% |
| Maturity = 1,00,000 × (1.01625)^20 | ₹1,38,042 |
| Interest | ₹38,042 |
Points to note
FD rates vary by bank and tenure, and senior citizens usually get a small extra rate. Interest is fully taxable at your income-tax slab, and banks deduct TDS if interest crosses the annual threshold, so your in-hand return is lower than the headline figure. Breaking an FD early typically incurs a penalty and a lower rate. Compare the effective annual yield, not just the quoted rate, when choosing between deposits with different compounding.
