How the FD Calculator works
A Fixed Deposit (FD) locks a lump sum for a fixed term at a fixed interest rate. This calculator computes your maturity amount and the interest earned, using compound interest.
FD rates are set by each bank and vary by tenure. Interest can be paid out periodically or compounded and paid at maturity — this calculator assumes compounding.
FD maturity (compound interest)
A = P × (1 + r/n)^(n×t)
P = principal, r = annual rate, n = compounding frequency per year, t = years.
Frequently asked questions
How is FD interest calculated?+
Most banks compound FD interest quarterly. The maturity amount uses the compound interest formula above.
Is FD interest taxable?+
Yes. FD interest is added to your income and taxed at your slab. Banks deduct TDS if interest crosses the annual threshold.
What happens if I withdraw an FD early?+
Premature withdrawal usually incurs a small penalty (often 0.5–1%) and a lower interest rate for the actual period held.
Which FD tenure is best?+
It depends on your goal and the rate curve. Compare rates across tenures; sometimes medium tenures offer the best rate.
