The FD Calculator estimates the maturity amount and total interest earned on a fixed deposit based on your principal, the annual interest rate, the deposit tenure, and how often the interest is compounded. Enter a lump-sum deposit amount, an interest rate as a percentage per annum, a tenure in years and months, and pick a compounding frequency (monthly, quarterly, half-yearly, or yearly) to see exactly what your deposit grows to at maturity.
It is built for bank and NBFC depositors, retirees planning income, and anyone comparing FD offers before locking in funds. Because most Indian banks compound FD interest quarterly, choosing the right frequency here matters: the same rate and tenure produce different maturity values depending on how often interest is added to the balance.
The tool uses the standard compound interest formula A = P x (1 + r/n)^(n x t), where P is the principal, r is the annual interest rate as a decimal, n is the number of compounding periods per year, and t is the tenure in years. The maturity amount is A, and the interest earned is A minus P. For quarterly compounding n = 4, for monthly n = 12, for half-yearly n = 2, and for yearly n = 1.
For example, a principal of 100000 at 7% per annum compounded quarterly for 5 years gives A = 100000 x (1 + 0.07/4)^(4 x 5) = 100000 x (1.0175)^20, which is about 141478, so the interest earned is roughly 41478. Fractional tenures are handled by converting months to a fraction of a year (6 months = 0.5), so t can be a non-integer value.
The effective annual yield shown is the actual yearly growth rate after compounding, which is (1 + r/n)^n - 1. This is always equal to or higher than the nominal rate, and the gap widens as compounding gets more frequent, which is why monthly compounding beats yearly at the same nominal rate.
No. It shows the gross maturity amount and interest before any tax. Banks deduct TDS on interest above the annual threshold, and FD interest is taxable as per your income slab, so your in-hand amount may be lower.
Use the frequency your bank actually applies. Most Indian banks compound FD interest quarterly, so quarterly is the common default, but always confirm with your specific bank or the FD terms.
This calculator models a cumulative FD, where interest is reinvested and paid at maturity. In a non-cumulative FD, interest is paid out periodically and does not compound, so the maturity value would just be the principal.
Yes. You can enter years and months together, such as 2 years 9 months. The tool converts the months into a fraction of a year and applies it in the compound interest formula.
Small differences can come from the exact compounding convention, day-count basis, or rounding your bank uses. This tool uses standard compound interest, so use its result as a close estimate rather than an exact contractual figure.
Yes, it is completely free with no sign-up. All calculations run locally in your browser, so your deposit amounts and rates are never sent to a server or stored.
No, this tool is for lump-sum fixed deposits. Recurring deposits involve monthly instalments and use a different formula, so use a dedicated RD or SIP-style calculator for those.
