FD Calculator
Calculate fixed deposit maturity amount with quarterly compounding.
Fixed deposits remain the default safe investment across India and much of Asia — you lock in an amount at a guaranteed rate for a fixed tenure. What banks rarely make obvious is the compounding: most FDs compound quarterly, which makes the effective annual yield slightly higher than the quoted rate.
This calculator uses standard quarterly compounding to show your maturity amount and total interest earned for any principal, rate and tenure. Compare offers across banks, check whether a longer tenure is worth it, or verify the maturity value printed on your FD receipt.
