How It Works
A Fixed Deposit (FD) is one of the most popular savings products offered by banks. You deposit a lump sum for a fixed tenure at a fixed interest rate, and the bank guarantees the return on maturity. Unlike market-linked investments, your principal and interest are not exposed to market risk.
FD Maturity Formula
A = P × (1 + r/n)n × t
Where P = principal, r = annual rate (decimal), n = compounding frequency per year (4 quarterly, 12 monthly, 1 yearly), and t = tenure in years.
Quarterly compounding is the bank standard
Most Indian banks compound FD interest quarterly by default — different from US savings accounts which usually compound monthly. A handful of banks offer monthly compounding (slightly higher effective yield), and very few use annual compounding. The compounding frequency makes a small but real difference: at 7.5% per annum, quarterly compounding produces an effective annual rate of ~7.71%, and monthly compounding produces ~7.76%.
Cumulative vs Non-Cumulative
A cumulative FD reinvests the interest every period — the balance grows and you receive principal + accumulated interest at maturity. A non-cumulative FD pays the interest out each period (quarterly / monthly cheque or auto-credit) — useful for retirees and others who want regular income. Principal is returned only at maturity; the per-period interest is paid out and does not compound.
Frequently Asked Questions
A Fixed Deposit is a banking product where you deposit a lump sum amount for a fixed period (typically 7 days to 10 years) at a pre-agreed interest rate. The bank guarantees both your principal and the agreed interest. At maturity you can withdraw the full amount, renew it, or take only the interest. FDs are low-risk because they are insured up to ₹5 lakh per depositor per bank by the DICGC.
