Compare and decide
Try different rates, tenures and compounding to compare banks, or switch on the senior citizen rate. Copy the full breakdown in one tap.
Grow it or draw an income.
The same deposit can compound quietly until maturity or pay you a regular income along the way. Here is how the common types differ.
Cumulative FD
The interest is added back to the deposit and compounds each quarter, then paid in full with the principal at maturity. Best for growing a lump sum you do not need to touch.
Non-cumulative FD
The interest is paid out at a regular interval, monthly, quarterly, half-yearly or yearly, and the principal is returned at maturity. Best for a steady income, which suits many retirees.
Tax-saver FD
A five year fixed deposit that qualifies for a deduction under Section 80C, up to the yearly limit. It has a lock-in, so it cannot be broken early, and the interest is still taxable.
What shapes your FD return.
The rate is only part of the story. Compounding, tenure, tax and a few other things decide what you actually take home.
Compounding frequency
Banks usually compound FD interest every quarter. The more often it compounds, the more you earn on the same rate, so monthly beats quarterly, which beats yearly.
Tenure
Longer tenures often carry a higher rate and let the interest compound for longer, so the maturity grows faster than the rate alone suggests.
Senior citizen rates
Most banks add around 0.50% a year for senior citizens. On a long deposit that small extra rate adds up to a meaningful amount at maturity.
Tax on the interest
FD interest is added to your income and taxed at your slab. Banks deduct TDS once the interest crosses a yearly threshold, unless you submit Form 15G or 15H.
Breaking it early
Withdrawing before maturity usually means a lower rate for the time it ran, plus a small penalty. A tax-saver FD cannot be broken at all during its lock-in.
Deposit insurance
Bank deposits are insured by the DICGC up to ₹5 lakh per depositor per bank, covering principal and interest together, which is worth keeping in mind for large sums.

Common fixed deposit questions.
It is a free online tool that works out what a fixed deposit will be worth at maturity. You enter the amount, the annual interest rate and the tenure, and it shows the maturity amount and the interest you earn, so you can compare banks and tenures before you invest.
A cumulative FD uses compound interest. The maturity amount is M = P × (1 + r ÷ n) raised to the power n × t, where P is the principal, r is the annual rate as a decimal, n is the number of times a year the interest compounds, and t is the tenure in years. Banks usually compound every quarter, so n is 4. This tool uses that by default and lets you change it.
In a cumulative FD the interest is not paid out. It is added back and compounds, then you receive the whole amount at maturity, so it grows a lump sum. In a non-cumulative FD the interest is paid out at a set interval, monthly, quarterly, half-yearly or yearly, and only the principal is returned at maturity. Non-cumulative suits anyone who wants a regular income from the deposit.
Most banks compound fixed deposit interest quarterly, which is the default here. Some offer monthly compounding. The more often it compounds, the more you earn for the same headline rate, because interest starts earning interest sooner. You can switch the compounding in the tool to match your bank.
It depends on the rate and tenure. At 7% a year compounded quarterly, ₹1,00,000 grows to about ₹1,07,186 in one year, ₹1,23,144 in three years and ₹1,41,478 in five years. Enter your own amount, rate and tenure in the calculator to see your figure.
Yes. Interest from a fixed deposit is added to your income and taxed at your income tax slab. Banks also deduct TDS once your interest with them crosses the yearly threshold, unless you are eligible to submit Form 15G or 15H to avoid it. This calculator shows the interest before any tax.
Usually yes. Most banks offer senior citizens about 0.50% a year more than the standard rate. Switch on the senior citizen option in the tool and it adds 0.50% to the rate you entered, so you can see the difference at maturity.
In most cases yes, but at a cost. The bank usually pays interest at a lower rate for the period the deposit actually ran and may charge a small penalty. A tax-saver FD is the exception, as it is locked in for five years and cannot be broken early.
Bank fixed deposits are among the safer places to keep money, and deposits are insured by the DICGC up to ₹5 lakh per depositor per bank, covering both principal and interest. For amounts above that, spreading deposits across banks keeps more of it inside the cover.
It will be very close. This tool uses the standard quarterly compounding formula that banks use. Small differences can come from how a bank rounds, how it treats a part-quarter at the end, or the exact day count. Always confirm the final figure with your bank before you rely on it.
Yes on both. It is free, there is no sign-up, and it runs entirely in your browser. Nothing you type is sent anywhere or stored, so your amounts stay on your own device.
It is a fixed deposit with a five year lock-in that qualifies for a deduction under Section 80C, up to the yearly limit, which can lower your taxable income. The trade-off is that you cannot withdraw it early, and the interest it earns is still taxable like any other FD.
Private by design: this calculator runs entirely in your browser, so nothing you type is uploaded or stored. It is provided free for estimates and educational use, and shows interest before any tax. It is not financial advice. Confirm rates, tenure and the final maturity with your bank before you invest.
