What Is a Fixed Deposit (FD)?

A fixed deposit (FD) — also called a term deposit or time deposit — is a savings product where you lock a lump sum with a bank or financial institution for a fixed period at a fixed interest rate. In exchange for leaving your money untouched until maturity, the bank pays you a higher, guaranteed rate than an ordinary savings account. Because the rate is locked at the outset, you know your exact maturity amount the day you open the deposit.

This FD return calculator runs the full interest math for any deposit, rate, tenure, and compounding frequency. Pair it with our compound interest calculator, CD calculator, savings calculator, investment calculator, and future value calculator to build a complete plan.

How an FD Works

Deposit a lump sum

You place a one-time amount with the bank and agree to a term — anywhere from a few days to ten years. The rate is fixed for that whole term.

Interest accrues and compounds

Interest is calculated at the agreed rate and added to your balance at set intervals — daily, monthly, quarterly, half-yearly, or yearly, depending on the product.

Choose cumulative or payout

In a cumulative FD interest is reinvested and compounds; in a non-cumulative FD it is paid out periodically as income while the principal stays put.

Receive the maturity amount

At the end of the term you get your principal plus all accrued interest (cumulative), or your principal back after receiving interest along the way (non-cumulative).

Four Ways to Use This FD Calculator

Find Your Maturity Amount

Enter your deposit, rate, and tenure to see exactly what your FD will be worth at maturity and how much of that is interest.

Compare Compounding

See how annual, quarterly, monthly, or daily compounding changes your return, and why the effective yield (APY) beats the headline rate.

Check Your Real Return

Add inflation and tax to reveal your after-tax, inflation-adjusted return — the number that actually reflects your purchasing power.

Compare FD Scenarios

Line up three deposits with different rates, tenures, and compounding to pick the FD that produces the most interest for you.

How FD Returns Are Calculated

For a cumulative FD, the maturity amount follows the compound interest formula A = P × (1 + r/n)^n×t. The principal P earns interest at annual rate r, compounded n times per year over t years. Because each round of interest itself earns interest, the balance grows along a curve — slowly at first, then faster as the term lengthens. The interest earned is simply the maturity amount minus your deposit.

For a simple-interest deposit the formula is A = P × (1 + r × t): interest is paid only on the original principal, so the balance grows in a straight line. A non-cumulative FD uses the same per-period interest of P × r ÷ n, but pays it to you each period instead of reinvesting it — your principal is returned unchanged at maturity. This calculator handles all three cases automatically based on the compounding and payout options you choose.

Simple vs Compound Interest

Simple Interest

Interest is calculated only on the original principal. A $100,000 deposit at 7% for 5 years earns a flat $7,000 a year — $35,000 total. Predictable, but it leaves money on the table compared with compounding.

Compound Interest

Interest earns interest. The same deposit compounded quarterly grows to roughly $141,478 — about $6,478 more than simple interest over five years, purely because earlier interest is reinvested.

Why the gap widens

The longer the tenure and the more frequent the compounding, the larger the advantage of compound interest. Over short terms the difference is small; over a decade it becomes substantial.

Which FDs use which

Cumulative FDs compound and are best for growing a lump sum. Non-cumulative FDs effectively act like simple interest because the interest is withdrawn each period and can't compound.

Cumulative vs Non-Cumulative FD

Cumulative FD

Interest is reinvested and paid as a single lump sum at maturity. Best when you don't need the income now and want maximum growth through compounding. The maturity amount is the largest of any option.

Non-Cumulative FD

Interest is paid out monthly, quarterly, half-yearly, or yearly as a regular income stream. Ideal for retirees and anyone who needs predictable cash flow from their savings — but the money doesn't compound.

Income vs growth

Choose cumulative to build wealth and non-cumulative to draw income. Two deposits with the same rate and tenure produce the same total interest only if the non-cumulative payouts are not reinvested elsewhere.

Tax timing

In many countries FD interest is taxed in the year it accrues, even on cumulative deposits where you don't receive it until maturity. Always check how your jurisdiction treats accrued versus paid interest.

Compounding Frequency Explained

Compounding frequency is how often the bank adds earned interest back to your balance. The more frequently it compounds, the more often your interest starts earning its own interest — so daily compounding produces a slightly higher return than annual compounding at the same nominal rate. The gap is largest between annual and quarterly compounding and shrinks quickly beyond monthly.

The fairest way to compare deposits is the effective annual yield (APY), which folds compounding into a single annual figure: APY = (1 + r/n)ⁿ − 1. A 7% rate compounded quarterly has an APY of about 7.19%, while compounded daily it's roughly 7.25%. Always compare FDs on APY rather than the headline rate.

How Inflation Affects FD Returns

A fixed deposit guarantees your nominal return, but inflation quietly erodes what that money can buy. If your FD earns 7% while inflation runs at 4%, your real return is only about 2.9% — the rest is offset by rising prices. Over a long tenure this matters: a maturity amount that looks large in future dollars may have far less purchasing power than it appears.

This calculator reports both the nominal maturity amount and the inflation-adjusted (real) value in today's money, plus your real annual return. When inflation is higher than your FD rate, the real return turns negative — your money grows on paper but loses purchasing power. That's the key reason conservative savers blend FDs with growth assets for long-term goals.

Tax on Fixed Deposits

FD interest is generally taxable as ordinary income in the year it is earned, and many banks withhold tax at source before crediting interest. Your effective return is therefore the after-tax figure, not the headline rate. Enter your marginal tax rate in the advanced options and the calculator subtracts tax from the interest portion only — your principal is never taxed.

Tax rules vary widely by country and account type. Some jurisdictions offer tax-saving FDs with a lock-in, tax-free thresholds for certain savers, or different treatment for accrued versus paid interest. Because this is a global tool, it lets you set any tax rate rather than assuming one country's rules — confirm the exact treatment that applies to you with a qualified tax professional.

Advantages & Disadvantages of Fixed Deposits

Money is locked in for the term
Interest is fully taxable in most jurisdictions
Lower long-term growth than equities or funds

FD vs Savings, CDs & Bonds

FD vs Savings Account

A savings account is fully liquid but pays a low, variable rate. An FD locks your money for a fixed term in exchange for a higher, guaranteed rate. Use savings for your emergency fund and FDs for money you won't need for months or years.

FD vs CD (Certificate of Deposit)

A CD is the U.S. equivalent of an FD — a time deposit at a fixed rate, federally insured up to the FDIC limit. The mechanics are nearly identical; the main differences are terminology, insurance schemes, and early-withdrawal penalty conventions.

FD vs Bonds

Bonds can offer higher yields and are tradable, but their market price fluctuates with interest rates and issuers can default. An FD's value never moves and the rate is guaranteed, at the cost of lower potential return and locked liquidity.

FD vs Mutual Funds

Funds target higher long-term returns but carry market risk and variable outcomes. FDs trade that upside for certainty. Many savers hold both: FDs for capital they must protect, funds for long-horizon growth.

How to Maximize FD Returns

Compare offers on APY rather than the nominal rate, and favor deposits that compound more frequently. Choose a cumulative FD if you don't need the income, so interest keeps compounding. Longer tenures usually pay higher rates and benefit most from compounding — but don't lock away money you may need, because early-withdrawal penalties can wipe out your interest.

Consider laddering: split your money across deposits of staggered maturities so part of it comes free each year for reinvestment or spending, smoothing out interest-rate changes. Where available, use tax-saving FD variants, and always keep enough in a liquid account that you never have to break an FD early.

Common FD Investment Mistakes

1
Comparing nominal rates instead of APY
Two FDs with the same headline rate can pay different amounts depending on compounding. Always compare the effective annual yield.
2
Locking in money you'll need
Breaking an FD early triggers a penalty that can erase much of your interest. Keep an emergency buffer in a liquid account first.
3
Ignoring inflation and tax
A 7% FD can have a near-zero real return after 4% inflation and tax. Always check the after-tax, inflation-adjusted figure, not the headline.
4
Choosing payout when you meant to grow
A non-cumulative FD pays income but doesn't compound. If your goal is growth, pick the cumulative option so interest is reinvested.
5
Putting everything in one deposit
A single large FD locks all your money to one rate and maturity. Laddering across terms gives you flexibility and reduces reinvestment risk.

Frequently Asked Questions

An FD return calculator estimates the outcomes of a fixed deposit: the maturity amount, total interest earned, effective annual yield, after-tax return, and inflation-adjusted value. You enter your deposit amount, interest rate, tenure, and compounding frequency, and it applies the standard compound or simple interest formulas to project exactly what your deposit will be worth at maturity.

For a cumulative FD, interest is calculated with the compound interest formula A = P × (1 + r/n)^(n × t), where P is the deposit, r is the annual rate, n is the number of compounding periods per year, and t is the tenure in years. Interest earned is A − P. Simple-interest deposits use A = P × (1 + r × t) with no compounding, and non-cumulative FDs pay P × r ÷ n each period as income.

The maturity amount is the total value of your FD at the end of its term — your original deposit plus all the interest it has earned. For a cumulative FD it is the single lump sum you receive at maturity. For a non-cumulative FD the principal is returned at maturity after you have already collected the interest as periodic payouts.

In a cumulative FD, interest is reinvested and compounds, then paid as one lump sum at maturity — best for growing a lump sum. In a non-cumulative FD, interest is paid out at regular intervals (monthly, quarterly, half-yearly, or yearly) as income, and the principal is returned unchanged at maturity. Cumulative deposits produce a larger maturity amount because the interest compounds.

The more frequently interest compounds, the higher the return at the same nominal rate, so daily compounding produces the highest maturity amount, followed by monthly, quarterly, half-yearly, and annually. The differences are largest between annual and quarterly compounding and become small beyond monthly. Compare deposits using the effective annual yield (APY), which already accounts for compounding.

Inflation reduces the purchasing power of your maturity amount. If your FD earns 7% while inflation runs at 4%, your real (inflation-adjusted) return is only about 2.9%. This calculator shows both the nominal maturity amount and its value in today's money, plus your real annual return. When inflation exceeds your FD rate, the real return is negative even though the balance grows.

In most countries, FD interest is taxable as ordinary income, and many banks deduct tax at source before crediting interest. Your effective return is therefore the after-tax figure. Enter your tax rate in the advanced options and the calculator subtracts tax from the interest portion only — your principal is never taxed. Tax rules vary by country, so confirm the exact treatment with a tax professional.

Usually yes, but early withdrawal typically triggers a penalty — often a reduction in the interest rate or a flat fee — which can significantly cut or even eliminate your interest. Some banks offer flexible or sweep-in FDs with easier access. Because penalties vary by institution, keep an emergency fund in a liquid account so you rarely need to break an FD early.

It is an accurate model of standard FD interest mathematics for the values you enter. Actual returns can differ slightly because of your bank's specific day-count convention, compounding policy, rounding, taxes, and any early-withdrawal penalties. Treat the results as a reliable planning estimate and confirm the exact maturity figure with your bank before depositing.

For money you won't need for a set period, an FD usually pays a higher, guaranteed rate than a savings account, which makes it better for growing idle cash. A savings account, however, keeps your money fully liquid for everyday needs and emergencies. Most people use both — a savings account for liquidity and FDs for funds earmarked for the medium term.
