FD Calculator

Calculate your Fixed Deposit maturity amount and interest earned instantly. Adjust deposit amount, interest rate, duration, and compounding frequency — results update as you type.

This calculator projects the maturity value of a Fixed Deposit using compound interest. Enter the principal, annual interest rate, tenure and compounding frequency, and it returns the maturity amount alongside the interest earned. Results are nominal and pre-tax — interest on an FD is taxable as income at your slab rate.

About this tool

A fast, accurate Fixed Deposit calculator using the standard compound interest formula — A = P × (1 + r/n)^(n×t) — the same formula used by all Indian banks. Enter your deposit amount, annual interest rate, and duration; the maturity value and interest earned update instantly as you type or drag the sliders.

Switch between yearly, quarterly, and monthly compounding to compare the impact of compounding frequency on your returns. The donut chart and progress bars visualise how much of the maturity amount is your original deposit versus the interest it earned. Quick preset chips let you jump to common amounts and rates without typing. All calculations run entirely in your browser — no data is sent to any server.

How to use

1

Enter your deposit amount

Type the amount or drag the slider. Use the quick chips — ₹10K, ₹50K, ₹1L, ₹5L, ₹10L — to jump to common amounts instantly.

2

Set the interest rate

Enter the annual interest rate offered by your bank. Use the preset buttons for common FD rates (5%–9%). Senior citizens can add the additional rate offered by their bank.

3

Choose duration and compounding

Set the FD tenure in years or months using the toggle. Then select the compounding frequency — quarterly is the most common for Indian bank FDs.

4

Read the results

The maturity value, interest earned, and invested amount update instantly. The donut chart and progress bars show the principal-vs-interest split visually.

A worked example

Take ₹5,00,000 deposited for 5 years at 7%, compounded quarterly. The formula A = P × (1 + r/n)^(n×t) becomes 5,00,000 × (1 + 0.07/4)^20, which gives a maturity value of about ₹7,07,389 — roughly ₹2,07,389 of interest.

Now change only the compounding frequency to annual, keeping the same 7% and the same five years. Maturity falls to ₹7,01,276. The same rate, the same money, the same term — and about ₹6,100 less, purely because interest was credited four times a year instead of once.

This is why comparing two FDs on the headline rate alone is misleading. Most Indian banks compound quarterly, but the frequency is worth confirming, and it is the reason a bank may advertise an “effective yield” slightly higher than the stated rate. Note also that the figures above are pre-tax: FD interest is taxable as income at your slab rate, and TDS may be deducted before it reaches you.

Frequently asked questions

Common questions about Fixed Deposit interest calculation, compounding, and tax in India.

Last updated

Maturity Amount = P × (1 + r/n)^(n×t), where P is the principal, r is the annual interest rate as a decimal, n is the number of compounding periods per year (1 for yearly, 4 for quarterly, 12 for monthly), and t is the time in years. This is the standard compound interest formula used by all Indian banks.

Compounding frequency determines how often interest is calculated and added to your principal. Monthly compounding earns slightly more than quarterly, which earns more than yearly, because interest starts earning interest sooner. For example, ₹1L at 7% for 3 years: yearly gives ₹1,22,504; quarterly gives ₹1,23,144; monthly gives ₹1,23,330.

As a rule, small finance banks offer the highest rates, private banks sit in the middle, and large public sector banks offer the least — the spread reflects differences in how easily each can raise deposits. Rates move every few months, so any specific figure quoted here would be wrong within a quarter. Check the bank's own site before committing. Note also that deposit insurance under DICGC covers a capped amount per depositor per bank, which is worth knowing when a small bank offers an unusually high rate.

Yes. Most Indian banks pay senior citizens a premium over the regular rate, and several offer a further increment for super-senior depositors. The exact premium is set by each bank and changes with their rate cards, so take the figure from your bank and enter that rate directly in the interest rate field.

Yes. FD interest is added to your total income and taxed at your slab rate — the maturity figures on this page are pre-tax. Banks also deduct TDS once interest crosses a threshold, and both the threshold and the rate are revised in Union Budgets, so check the current limits on the Income Tax Department site rather than assuming last year's. If your total income falls below the taxable limit, submitting Form 15G (or 15H for senior citizens) prevents the deduction.

Premature withdrawal is allowed at most banks but attracts a penalty of 0.5%–1% reduction in the applicable interest rate. The actual interest earned will be recalculated at the lower rate for the actual holding period. Some banks waive premature withdrawal penalties for FDs held for more than a certain duration.

For FDs of less than 6 months or 180 days, most banks apply simple interest, not compound interest. This calculator uses compound interest, which is appropriate for standard FD tenures of 6 months and above. For very short-tenure FDs, the actual interest may be marginally lower than shown.
