How FD interest is calculated
A fixed deposit (FD) locks a lump sum with a bank or NBFC for a fixed tenure at a fixed interest rate. The interest compounds — each period's interest is added to your balance and itself earns interest. The maturity amount is:
where P is your deposit, r the annual interest rate, n how many times interest compounds per year (12 monthly, 4 quarterly, 2 half-yearly, 1 yearly), and t the tenure in years. Quarterly compounding is the most common default for Indian bank FDs. More frequent compounding earns slightly more at the same rate.
TDS on interest
Banks deduct 10% TDS once interest with that bank crosses ₹40,000 in a year (₹50,000 for senior citizens). FD interest is taxable at your slab.
Premature withdrawal
Breaking an FD early usually costs a 0.5%–1% penalty on the applicable rate, and you earn interest only for the period the money stayed.
FD vs RD
An FD invests one lump sum upfront; a recurring deposit (RD) builds up from fixed monthly instalments. Both give guaranteed, fixed returns.
Frequently asked questions
Most Indian bank FDs use compound interest. Your maturity amount is principal × (1 + r/n)^(n×t), where r is the annual rate, n the number of times interest compounds per year (4 for quarterly), and t the tenure in years. Interest earned is the maturity amount minus your original deposit.
