How Fixed Deposit Maturity Is Calculated

Banks grow your FD with compound interest: M = P × (1 + r/n)n×t — where P is your deposit, r the annual rate as a decimal, n the number of compounding periods per year, and t the tenure in years. Most Indian banks compound quarterly (n = 4), which is why this calculator defaults to it.

Example: ₹1,00,000 at 7% for 5 years, compounded quarterly → M = 1,00,000 × (1 + 0.07/4)20 ≈ ₹1,41,478, i.e. ₹41,478 interest. The same deposit compounded only yearly would mature to ₹1,40,255 — frequency matters.

The effective annual yield shown above converts the quoted rate into the true one-year return after compounding: (1 + r/n)n − 1. A "7%" quarterly FD really earns ~7.19% a year.
