How is FD interest calculated?
Fixed deposits use compound interest where interest earned is reinvested each compounding period, growing your total at an accelerating rate.
Simple FD: A = P × (1 + r×t)
Eff. Yield: EY = (1 + r/n)^n − 1
where: P=principal · r=annual rate · n=compounding freq · t=years
More frequent compounding = more interest. Monthly gives marginally more than quarterly, which beats half-yearly and annual. The gap widens with higher rates and longer tenures.
Banks deduct TDS at 10% if annual FD interest exceeds ₹40,000 (₹50,000 for seniors). Submit Form 15G/15H if your total income is below the taxable limit to avoid TDS deduction.
Breaking an FD before maturity attracts a penalty — typically 0.5–1% lower interest rate. Senior citizen FDs generally have higher rates (0.25–0.5% extra).
Bank deposits are insured up to ₹5 lakh per depositor per bank by DICGC. For larger amounts, spread across multiple banks to maximise insurance coverage.
