How to use this FD calculator
Fixed deposits remain the default safe haven for Indian savers, offering predictable returns without market risk. But the headline interest rate alone does not tell you the maturity amount — compounding frequency and tenure quietly shape the outcome.
This calculator computes your FD's maturity value and total interest using the rate, tenure and compounding frequency you choose, so you can compare offers from different banks on equal terms.
How compounding frequency matters
Most banks compound FD interest quarterly. The more often interest is compounded, the higher the effective yield, even at the same stated rate.
The calculator lets you change the compounding frequency so you can see why an FD compounded quarterly beats one compounded annually at the same nominal rate.
Tax on FD interest
FD interest is fully taxable at your income-tax slab. Banks deduct TDS at 10% if interest in a year exceeds ₹40,000 (₹50,000 for senior citizens), provided your PAN is registered.
This pre-tax calculator shows gross maturity; your post-tax return depends on your slab, so high earners keep less than the headline figure.
Premature withdrawal and laddering
Breaking an FD early usually attracts a penalty and a lower effective rate, so match the tenure to when you will actually need the money.
Splitting a large sum across multiple FDs with staggered maturities (laddering) improves liquidity without abandoning the rate.
