How to use the Fixed Deposit (FD) Calculator
- Enter the deposit amount and interest rate.
- Enter the tenure and compounding frequency.
- Read maturity value and interest.
How it works
Maturity = P × (1 + r/n)^(n×t), where P is the deposit, r the annual rate, n compounding periods per year and t years. Effective annual yield = (1 + r/n)^n − 1.
Worked example
500,000 at 7% compounded quarterly for 5 years matures at about 707,500, earning roughly 207,500 of interest.
Good to know
Banks usually compound quarterly; check your deposit terms.
Interest may be taxable; this estimate is pre-tax.
Premature withdrawal often carries a penalty not modelled here.
