FD Calculator
Calculate fixed-deposit maturity and interest for any principal, rate, tenure and compounding frequency.
How it works
A = P × (1 + r ÷ n)^(n × t) — P = principal, r = annual rate, n = compounds per year, t = years
A fixed deposit locks a lump sum for a set tenure at a fixed rate, and interest compounds at the frequency the bank uses (quarterly is most common in India). Because interest earns interest, more frequent compounding raises the maturity slightly. The interest earned is simply the maturity amount minus your principal.
Worked example
₹1,00,000 at 7% compounded quarterly for 5 years matures to about ₹1,41,478 — roughly ₹41,478 of interest on the original deposit.
Frequently asked questions
Is FD interest taxable?
Yes. FD interest is added to your income and taxed at your slab rate, and banks deduct TDS once interest crosses the annual threshold. Factor tax in when comparing an FD to other options.
What compounding should I pick?
Most Indian banks compound FD interest quarterly. Monthly-payout FDs usually pay simple interest instead, so use the option that matches your specific deposit.
Can I break an FD early?
Usually yes, but the bank applies a lower rate and often a small penalty for premature withdrawal, so the effective return drops. Check the terms before locking a long tenure.
