How this FD calculator works
You enter a deposit amount, an annual interest rate and a term in years. The tool applies the compound-growth formula maturity = principal × (1 + rate)^years and shows the maturity value and the interest earned. Interest is compounded once a year.
Worked example
Rs. 1,00,000 at 7% for 5 years gives 1,00,000 × 1.075 = about Rs. 1,40,255, so the interest is about Rs. 40,255.
Why your bank's figure may be higher
Most Indian banks compound cumulative fixed deposits quarterly. The same deposit at 7% compounded quarterly for 5 years matures at about Rs. 1,41,478, roughly Rs. 1,200 more than this calculator shows. Treat the result as a slightly conservative estimate and check the figure on your bank's rate card or deposit receipt.
What it does not cover
- Tax: FD interest is taxable at your slab rate and banks may deduct TDS. The result is pre-tax.
- Payout FDs: if you take interest monthly or quarterly instead of reinvesting, there is no compounding and the maturity figure does not apply.
- Partial years and premature withdrawal penalties are not modelled; use whole or decimal years only.
