Behind the calculation
Maturity = deposit × (1 + annual rate ÷ compounds per year)compounds per year × years. Enter a nominal annual rate. Interest is reinvested each compounding period.
This models a cumulative fixed deposit with a whole-year term. It excludes tax, TDS, fees and premature-withdrawal penalties. Banks may use different day counts and rounding. Confirm the actual maturity and terms with your bank.
