What Is a FD Calculator?

A fixed deposit locks a lump sum with a bank for a fixed term in exchange for a guaranteed interest rate. The maturity value uses the standard compound-interest formula A = P · (1 + r/n)^(n·t). Indian banks compound quarterly by default; many global banks compound monthly, which produces a slightly higher maturity at the same headline rate.

Retirees comparing senior-citizen rates across banks use the tool to see whether a 0.25% higher rate offsets the inconvenience of switching. Salaried savers planning short-term goals (emergency fund, tax-saving FD) use it to confirm the maturity figure before locking funds. Inputs are deposit amount, annual rate, term and compounding frequency; outputs are maturity amount, total interest and the effect of switching compounding on the same rate.

FD interest is fully taxable as ordinary income in India and TDS kicks in past ₹40,000 per year (₹50,000 for seniors). Figures shown are pre-tax — subtract your slab rate for take-home. General information only; confirm specifics with the bank.

Frequently Asked Questions

How often do FDs compound?
Most Indian banks compound fixed deposits quarterly by default. Some offer monthly compounding for higher amounts; this tool lets you choose.
Is FD interest taxable?
Yes. Interest earned on fixed deposits is added to your taxable income, and banks deduct TDS once interest in a year crosses the prescribed threshold.
What if I withdraw early?
Premature withdrawal usually incurs a penalty of 0.5% to 1% on the applicable rate, plus a lower interest rate for the actual period the deposit was held.
