Fixed deposit maturity and interest, cumulative or with monthly or quarterly payouts
Estimates only, not financial advice. What you type stays on your device. Updated on 25 Oct 2026.A fixed deposit pays a set rate for a set term, so the maturity amount is known the day you open it. 1 lakh rupees at 7 per cent for 5 years comes to about 1.41 lakh compounded quarterly. Payout options change the figure, and the interest is taxable.
Interest compounded quarterly at 7% a year; a month is 1/12 of a year and a day 1/365. Before tax.
Estimates for information only, not financial advice. The rate is what you enter; banks count actual days, so their figure can differ by a few rupees.

The FD calculator works out what a bank fixed deposit pays. Enter the amount, the rate your bank quotes and the tenure in years, months and days. For a cumulative deposit you get the maturity value, the interest earned and the balance at the end of each year. For a payout deposit you get the interest paid to you every month or quarter and the total over the term.
Most Indian banks add interest to a cumulative FD every quarter. ₹1,00,000 at 7% for 5 years grows to about ₹1,41,478 with quarterly compounding, against ₹1,40,255 if interest were added only once a year. Senior citizens can switch on the extra rate their bank offers; the calculator adds it to the rate you enter and never assumes a bank's rate for you.
The formula, in plain text, with r = rate ÷ 100 and n = compounding periods a year: maturity = P × (1 + r ÷ n)^k × (1 + r × f), where k is the number of complete periods in the tenure and f the part of a year left over, which earns simple interest. For a whole number of periods this is the familiar P × (1 + r ÷ n)^(n × years). A month counts as one twelfth of a year and a day as 1/365.
With monthly payouts, interest is earned quarterly but paid monthly, so banks pay a little less each month: monthly interest = P × r ÷ (12 + r). With quarterly payouts it is P × r ÷ 4.
Banks count actual days, and some pay simple interest on deposits shorter than six months, so your bank's figure can differ slightly. FD interest is taxable and banks deduct TDS above a yearly limit; confirm the current rule for your tax year. Everything runs in your browser. Estimates only, not financial advice.

At 7% a year with interest added every quarter, ₹1,00,000 grows to about ₹1,41,478 in 5 years, so about ₹41,478 of interest. At 7.5% it would be about ₹1,44,995. Use the rate your bank quotes for that tenure, because rates differ by bank and by tenure.
Most banks add interest to a cumulative fixed deposit every quarter, so the interest earns interest. The maturity value is P × (1 + r/4)^(4 × years) for a whole number of quarters. Days left over after the last full quarter earn simple interest. Banks count actual days, so their figure can differ by a few rupees.
Interest on a monthly payout deposit is earned quarterly but paid to you every month, which is ahead of time. Banks pay a discounted amount so the three monthly payments are worth one quarter's interest: monthly interest = P × r / (12 + r). ₹1,00,000 at 7% pays about ₹580 a month rather than ₹583.
Most banks offer senior citizens an extra rate on fixed deposits, but the amount varies by bank and tenure. Switch on the senior citizen option and enter the extra your bank quotes; the calculator adds it to the rate you entered. It does not assume any bank's rate.
Yes. FD interest is added to your income and taxed at your slab rate, and banks deduct TDS once the interest they pay you in a year crosses the limit in the income tax rules. The figures here are before tax. Confirm the current rules for your tax year before relying on them.
Yes. Enter the tenure in years, months and days in any mix, for example 0 years, 0 months and 444 days. The calculator counts complete quarters first and gives simple interest on the days left over, which is how banks treat odd tenures.
