Fixed Deposit (FD) Calculator
Estimate maturity for a cumulative Indian bank FD. Enter the annual rate offered by your bank; the estimate compounds interest quarterly and uses your actual calendar dates.
Interest = opening balance × annual rate × actual days ÷ days in year, reinvested each quarter. Actual-year mode splits periods at 1 January and uses 365 or 366 for each segment. Calculations retain full precision; displayed amounts are rounded to paise.
Enter a valid deposit amount, rate, start date and tenure (up to 40 years).

How this tool helps
Estimate a cumulative fixed deposit using quarterly compounding, an entered annual rate and the deposit’s actual start and maturity dates. The schedule shows completed quarters and any final partial period.
- Enter the rate shown by your bank; rates vary by bank, customer type and tenure.
- Choose the bank’s disclosed day-count basis; it applies to every quarter and the final partial period.
- The estimate is before tax deduction at source and may differ because banks can apply product-specific rounding or terms.
Worked example: Estimate a cumulative fixed deposit
- Deposit amount: ₹1,00,000
- Annual interest rate: 7%
- Tenure: 1 year
- Compounding: quarterly
Review the maturity estimate together with the quarter-by-quarter schedule, including days in each period and interest credited.
The calculator applies the selected day-count basis to actual dates. Bank-specific compounding, rounding, TDS and product rules may differ.
Frequently asked questions
How is interest estimated for a cumulative FD?
Each quarter earns opening balance × annual rate × actual days ÷ days in year. Interest is added at quarter end. Actual-year mode splits at 1 January to use 365 or 366 days; the final partial period uses the same method.
Which day-count basis should I use?
Actual calendar-year days (365 or 366) is the default. A fixed 365-day option is available for comparison. Use your bank’s disclosed terms; this calculator does not confirm any bank’s internal convention.
Will this exactly match my bank’s maturity receipt?
Not always. Bank-specific rounding, product terms, holiday treatment, TDS and premature-withdrawal rules can change the amount. Treat the result as an estimate and use the bank’s FD receipt as authoritative.
