Worked Example
Deposit: ₹2,00,000. Rate: 7% p.a.. Tenure: 3 years. Compounding: Quarterly.
Rate per quarter = 7% / 4 / 100 = 0.0175
Periods = 4 × 3 = 12 quarters
A = P × (1 + r/n)^(n×t)
= 200000 × (1.0175)^12
≈ ₹2,46,287
Total interest earned = 2,46,287 − 2,00,000 ≈ ₹46,287Switching the same deposit to monthly compounding (n = 12) instead of quarterly raises the maturity amount slightly, since interest gets added to the principal more often — this is why the compounding frequency field changes your result even at the same stated rate.
Things to know about FD interest
- A higher compounding frequency (monthly vs. quarterly vs. yearly) always produces a slightly larger maturity amount at the same nominal rate, because interest starts earning interest sooner.
- This calculator assumes a cumulative FD where interest is reinvested until maturity — a non-cumulative FD that pays interest out periodically won't grow to the same figure, since those payouts stop compounding.
- Breaking an FD before maturity usually triggers a penalty and a lower applicable rate, so the real payout on early withdrawal will be less than the maturity amount shown here.
- This tool doesn't account for TDS or income tax on the interest earned — treat the result as a pre-tax planning estimate and confirm exact figures with your bank.
Is FD Calculator safe?
Yes. The compound-interest formula — applied at whichever compounding frequency you choose, from yearly to monthly — runs locally in your browser, so your deposit amount and tenure never leave your device.
Frequently Asked Questions
How is FD maturity amount calculated?
This calculator uses the standard compound interest formula: A = P × (1 + r/n)^(n×t), where P is the deposit amount, r is the annual interest rate, n is the number of compounding periods per year, and t is the tenure in years.
Which compounding frequency should I choose?
Most Indian banks compound FD interest quarterly, even though interest is credited at maturity for cumulative deposits. Check your bank's FD certificate or terms, and select the matching frequency for an accurate estimate.
Does this include TDS or tax on FD interest?
No. This calculates only the maturity amount based on the deposit, rate and tenure you enter. FD interest is taxable as per your income slab, and banks may deduct TDS if interest exceeds the applicable threshold.
Does this work for both cumulative and non-cumulative FDs?
This calculator assumes a cumulative FD, where interest is reinvested and paid out at maturity. For a non-cumulative FD with periodic interest payouts, the payouts aren't reinvested, so the actual maturity value will differ.
What if I withdraw my FD before maturity?
This calculator estimates the value at full maturity only. Premature withdrawal usually attracts a penalty and a lower applicable interest rate, so your actual payout on early withdrawal will be less than the amount shown here.
