Calculate fixed deposit maturity and interest for any rate, tenure, and compounding frequency.
A fixed deposit locks a lump sum with a bank or NBFC for a set tenure at a fixed interest rate, and in return you get a known maturity amount on a known date. The catch is that the number the bank quotes is an annual rate, not the amount you will actually receive. This FD Calculator closes that gap by turning your principal, rate, tenure, and compounding frequency into the exact maturity value and the interest earned, so you can compare offers before you commit money for months or years.
Using it is quick. You enter the deposit amount, the annual interest rate the bank is offering, the tenure in years or months, and how often the interest compounds, usually quarterly for Indian banks but sometimes monthly or yearly. The tool then shows the maturity amount and the total interest, and you can change any input to see the effect instantly. It helps to try a couple of tenures side by side, because a slightly longer term or a more frequent compounding cycle can move the final figure more than people expect.
The math behind it is the compound interest formula, where the maturity amount equals the principal multiplied by (1 plus the rate divided by the number of compounding periods per year), raised to the power of the periods times the years. As a rough illustration, one lakh at 7 percent compounded quarterly for five years grows to roughly 1.41 lakh, so about 41,000 in interest. The calculator assumes a fixed rate for the whole term and does not deduct TDS or tax on the interest, so treat the maturity figure as pre-tax and check the rate your bank is actually quoting today.
Reach for this instead of a generic savings estimate when the rate is truly locked, which is what separates an FD from a recurring deposit or a market-linked investment. A recurring deposit takes a fixed sum every month rather than one lump, and a mutual fund has no guaranteed return at all. If your money is going in once and sitting untouched at a promised rate, an FD calculation gives you a firm answer rather than a projection.
People use it to compare two banks quoting rates that look close but pay out differently, to decide between a shorter and a longer tenure, to plan how much to deposit now to reach a target like a school fee or a down payment, and to check whether a senior citizen rate makes a meaningful difference. Because you can edit the inputs freely, it doubles as a planning tool rather than a one-shot answer.
Everything runs in your browser. Your deposit figures are never uploaded, there is no sign-up, and nothing is stored on a server, so the only limit is your own device. Use it as often as you like while you shop around for the best fixed deposit rate.
No, it shows the pre-tax maturity amount and interest. Banks deduct TDS once your interest crosses the annual threshold, and the interest is added to your taxable income, so your actual in-hand return can be lower. Check the current TDS rules and your own tax slab.
With quarterly compounding, interest is added to the balance four times a year, so each new quarter earns interest on the interest already credited. Over a long tenure that snowballing lifts the maturity value slightly above the same rate compounded once a year. The gap widens the longer the deposit runs.
Not accurately. This tool assumes a single lump sum sitting for the whole term, while a recurring deposit or SIP adds money every month, which needs a different formula. Use a dedicated RD or SIP calculator for those.
Match whatever your bank states in the FD terms, which for most Indian fixed deposits is quarterly. Some deposits compound monthly or pay simple interest for very short tenures, so read the offer document rather than guessing.
No, it assumes you hold the deposit to maturity at the quoted rate. Breaking an FD early usually means a lower rate plus a penalty, so the real payout would be less than the figure shown here.
The calculator treats it as fixed, which is how a standard FD works once booked. If you are looking at a floating-rate product, the actual return can move with the market and this estimate will not match.
Yes, enter the tenure in the unit the tool provides and it adjusts the compounding periods accordingly. Short tenures in months work fine, just make sure the rate you enter is the one your bank offers for that specific term.
