How it works

A Fixed Deposit (FD) pays a guaranteed interest rate for a chosen tenure. Most Indian banks compound FD interest every quarter, so your interest starts earning interest four times a year.

Maturity = P × (1 + r/4)4t

Here P is the deposit, r is the annual rate, and t is the tenure in years. Quarterly compounding is why an FD's effective yield is slightly higher than its headline rate — a 6.5% FD compounded quarterly effectively yields about 6.66% per year.

FDs suit money you will need on a known date within a few years — an emergency fund's second layer, a near-term purchase, or capital you cannot expose to market swings. Remember that FD interest is taxed at your income-tax slab each year, which lowers the post-tax return considerably for higher slabs; that is worth comparing against debt mutual funds for longer horizons.

Frequently asked questions

Most Indian banks compound quarterly for FDs of a year or more, which is what this calculator uses. Some banks and NBFCs differ slightly; check the deposit receipt for the exact basis.
Banks deduct TDS if interest in a financial year exceeds the applicable threshold (₹50,000 for most depositors, ₹1,00,000 for senior citizens, as per recent rules). The interest is still taxable at your slab; TDS is only an advance collection.
An FD offers certainty of return and (up to ₹5 lakh per bank, via DICGC) insured safety. Debt funds offer no certainty but can be more tax-efficient and flexible for horizons above three years. The choice depends on the goal, not just the rate.
