FD Calculator
See what a fixed deposit will be worth at maturity, how much interest it earns each year, what a monthly payout would be — and how much to deposit to reach a goal.
At a glance
- Calculates FD maturity amount and interest with quarterly compounding — the method Indian banks use — or monthly, half-yearly, yearly or simple interest.
- Handles any tenure in years, months and days (such as 444 days): whole quarters compound and the part period at the end earns simple interest, as banks calculate it.
- Works out monthly, quarterly, half-yearly or yearly interest payouts, using the discounted rate banks apply to monthly payouts.
- Adds the senior citizen extra of 0.5%, estimates tax at your slab with 4% cess, and warns when interest crosses the TDS limit (₹50,000 a year; ₹1,00,000 for senior citizens).
- Goal mode tells you how much to deposit today to reach a target amount.
- Shows a year-by-year chart and schedule (downloadable as CSV) and the same deposit over 1, 2, 3, 5 and 10 years. Nothing is uploaded.

FD formula
For a cumulative FD compounded quarterly: A = P × (1 + r/4)^(4t), where P is the deposit, r the yearly rate as a decimal and t the tenure in years. ₹1,00,000 at 7% for 5 years grows to 1,00,000 × 1.0175²⁰ = ₹1,41,478.
Because interest is added every quarter, a 7% FD really earns 7.19% a year — the effective annual yield. When the tenure is not a whole number of quarters, the leftover days earn simple interest on the balance.
A payout FD does not compound: a quarterly payout is P × r/4. Monthly payouts are paid at a slightly discounted rate because you receive the money earlier.
Tax on FD interest in India
- FD interest is added to your income and taxed at your slab rate, every year, even on a cumulative FD.
- A bank deducts 10% TDS when your total interest with it crosses ₹50,000 in a financial year (₹1,00,000 for senior citizens) — 20% if it has no PAN.
- If your total income is below the taxable limit, submit Form 15G (or 15H for senior citizens) to avoid TDS.
- Tax-saving FDs have a 5-year lock-in and no premature withdrawal.
- Deposits are insured by DICGC up to ₹5 lakh per depositor per bank, including interest.
