FD calculator: see what your fixed deposit will be worth

Enter your deposit amount, interest rate and tenure to see the maturity value and interest earned — with the compounding frequency your bank actually uses.

Your FD details

Deposit amount ₹1,00,000

Interest rate (p.a.) 7%

Tenure 5 years

Compounding frequency

Most Indian bank FDs compound quarterly by default. Some compound monthly or half-yearly — check your bank's specific terms.

An estimate, before tax. This assumes the interest rate stays constant for the full tenure and that interest is reinvested (a cumulative FD), not paid out. FD interest is taxable as income, and banks deduct TDS if your interest crosses the prevailing threshold — the maturity value shown here does not account for tax.

How FD interest is calculated

A cumulative fixed deposit compounds interest at a set frequency and pays out the full amount at maturity:

Maturity value = P × (1 + r/n)^{n × t}
where P is the deposit amount, r is the annual interest rate, n is the compounding frequency per year, and t is the tenure in years.

More frequent compounding produces a slightly higher maturity value for the same quoted annual rate, because interest starts earning interest sooner. The difference is usually small but genuinely there — try switching between quarterly and monthly above to see it.

Cumulative vs non-cumulative FDs

A cumulative FD reinvests interest and pays everything at maturity — this is what this calculator assumes. A non-cumulative FD instead pays out interest periodically (monthly, quarterly or annually) as income, typically calculated on a simple-interest basis for each payout. If you want to compare payouts you receive along the way, this calculator will overstate your total, since it assumes reinvestment.

Tax on FD interest. Interest earned on an FD is fully taxable as income at your slab rate, and banks deduct TDS once your total interest crosses the prevailing threshold in a financial year — the exact threshold and rules change with tax law, so check current rules or ask your bank rather than relying on a fixed number here.

FAQ

Common questions

Does compounding frequency really matter much?

For a typical FD it's usually a small difference — often well under 1% of the maturity value between quarterly and annual compounding — but it's real, and it grows with a higher rate and longer tenure. Compare the frequencies above to see the exact difference for your numbers.

Can I withdraw an FD before maturity?

Most banks allow premature withdrawal but charge a penalty, typically a reduction in the interest rate applied. Check your bank's specific premature withdrawal terms before booking, especially for a long tenure.

Is FD interest guaranteed?

The rate is fixed for the tenure you book at that rate, unlike market-linked investments. It is not risk-free in an absolute sense (bank deposits carry limited deposit insurance up to a prescribed amount per depositor per bank), but the rate itself does not fluctuate with markets once booked.

How is this different from an RD?

An FD is a lump sum deposited once. An RD is a fixed amount deposited every month. Use the RD calculator if you're saving monthly rather than depositing a lump sum.
