FD Calculator —
Maturity & Interest
Calculate the maturity amount and total interest on any fixed deposit — enter your principal, rate and tenure, pick the compounding frequency and get the effective yield instantly. Plus current FY 2025-26 bank rates and TDS rules.
An FD calculator computes your maturity amount using the compound-interest formula A = P × (1 + r/n)n×t. Enter the principal, annual rate and tenure, and it returns the total interest and maturity value. FY 2025-26 rates: SBI/HDFC/ICICI 6.8–7.5%, small finance banks up to 8.5%, seniors get +0.25–0.50%. TDS at 10% applies once annual FD interest crosses ₹50,000 (₹1,00,000 for seniors) — submit Form 15G/15H to avoid it if your income is below the exemption limit.
FD Interest & Maturity Calculator
Enter your deposit details below. The calculator applies compound interest at your chosen frequency (most Indian banks compound quarterly) and shows the maturity amount, total interest and effective annual yield.
A cumulative FD compounds interest back into the principal and pays everything at maturity — best for wealth building. A non-cumulative FD pays interest out monthly/quarterly — best for retirees needing regular income. For the same stated rate, a cumulative FD gives a higher effective yield because of compounding.
How FD Interest Is Calculated
Most Indian banks use compound interest with quarterly compounding for cumulative FDs. The maturity amount is:
A = P × (1 + r/n)n×t
Where A = maturity amount, P = principal, r = annual rate (decimal), n = compounding periods per year, t = tenure in years.
Worked example: ₹1,00,000 at 7.0% p.a. for 1 year, compounded quarterly → A = 1,00,000 × (1 + 0.07/4)4 = 1,00,000 × (1.0175)4 = ₹1,07,186, so interest earned = ₹7,186.
| Compounding | Periods / year (n) | Maturity on ₹1L @ 7% for 1 yr | Effective yield |
|---|---|---|---|
| Annually | 1 | ₹1,07,000 | 7.00% |
| Half-yearly | 2 | ₹1,07,123 | 7.12% |
| Quarterly (typical) | 4 | ₹1,07,186 | 7.19% |
| Monthly | 12 | ₹1,07,229 | 7.23% |
More frequent compounding raises the effective yield slightly for the same stated rate.
FD Interest Rates — Bank Comparison
Rates below are indicative for the general public (non-senior). Senior citizens typically earn an extra 0.25–0.50% p.a. Always verify the current rate for your exact tenure on the bank's official website before investing.
| Bank | FD rate range (p.a.) | Best tenure | Senior add-on |
|---|---|---|---|
| SBI | 6.8–7.5% | 400 days / 2–3 yrs | +0.50% |
| HDFC Bank | 7.0–7.5% | 15 / 21 months | +0.25–0.50% |

| AU Small Finance Bank | 8.0–8.5% | 12–18 months | +0.25–0.50% |
Small finance banks carry DICGC insurance up to ₹5 lakh per depositor per bank, same as scheduled commercial banks.
FD interest is taxed as "Income from Other Sources" at your slab rate — there is no special concessional rate. If you are in the 30% bracket, your FD interest is taxed at 30% plus cess. TDS deducted by the bank is only a part-payment; you must still report the full interest in your ITR and pay any balance (or claim a refund).
TDS on FD Interest — Rules & Thresholds
Banks deduct TDS under Section 194A once your annual FD interest from that bank crosses the threshold. The threshold applies per bank — split FDs across banks each get their own threshold, but all interest must still be reported in your ITR.
| Category | TDS-free threshold / bank / year | TDS (with PAN) | TDS (no PAN) | Avoid via |
|---|---|---|---|---|
| Regular (below 60) | ₹50,000 | 10% | 20% | Form 15G |
| Senior citizen (60+) | ₹1,00,000 | 10% | 20% | Form 15H |
Senior-citizen threshold raised to ₹1,00,000 from FY 2025-26 (earlier ₹50,000).
Submit Form 15G / 15H at the start of the financial year to stop TDS if your total income is below the basic exemption limit. Submitting these forms when income is above the limit is an offence under Section 277.
