Calculate fixed deposit maturity value and interest earned. Free online FD calculator with formula, examples, and FAQ for FD investors.
A Fixed Deposit (FD) is a safe investment where you deposit a lump sum for a fixed period at a guaranteed interest rate. The FD calculator computes the maturity value based on the principal, interest rate, tenure, and compounding frequency. FDs are popular for capital preservation and guaranteed returns, making them ideal for conservative investors and emergency fund parking.
Maturity Value = P × (1 + r/n)^(n×t)Where P is the principal amount, r is the annual interest rate (as a decimal), n is the compounding frequency per year (12 for monthly, 4 for quarterly, 2 for half-yearly, 1 for yearly), and t is the tenure in years. More frequent compounding results in higher maturity values due to interest-on-interest effect.
