How is this calculated?
A = P × (1 + r ÷ n)^(n × t)
P = deposit · r = yearly rate ÷ 100 · n = compounding periods per year · t = tenure in years
Deposits under 6 months: A = P × (1 + r × t)Runs in your browser — nothing you enter leaves this device.
An estimate using the standard formula. Your bank’s figure may differ slightly due to day-count and rounding rules. Not financial advice.
About this tool
What it does
This calculator shows what a fixed deposit will be worth when it matures and how much interest it earns, using the same compound interest method banks use for cumulative deposits. Choose how often interest is compounded to match your bank’s terms.
How to use it
- Enter the amount you plan to deposit.
- Set the yearly interest rate your bank quotes for that tenure.
- Choose the tenure in months — the hint shows it in years and months.
- Pick how often interest is compounded. Most Indian banks use quarterly.
- Read the maturity amount, interest earned and effective yearly yield, then copy the link to compare deposits.
Limits and your data
- This models a cumulative (re-investment) deposit, where interest is added to the balance. Deposits that pay interest out monthly or quarterly earn slightly less.
- Tax deducted at source (TDS) and income tax on interest are not deducted.
- Senior citizen and special-tenure rates vary by bank — enter the exact rate you are offered.
- Premature withdrawal usually carries a penalty that lowers the rate.
- The calculation runs entirely in your browser and nothing is sent anywhere. Your figures appear only in the page address, so a link you share reopens the same deposit.
Questions
Why is the effective yield higher than the interest rate?
Because interest earns interest. At 7% compounded quarterly, each quarter’s interest is added to your balance, so over a full year you earn about 7.19%.
Which compounding should I choose?
Check your deposit terms. Most Indian banks compound quarterly; some small finance banks and corporate deposits compound monthly or yearly.
Is FD interest taxable?
Yes, interest is added to your income and taxed at your slab rate. Banks deduct TDS when interest crosses the yearly threshold unless you submit Form 15G or 15H where eligible.
Why does a 3-month deposit show simple interest?
Banks don’t compound deposits shorter than six months; they pay simple interest for the days the money is held. The calculator follows that convention.
