What Is a Fixed Deposit?

A Fixed Deposit (FD) is one of the safest investment options in India. You deposit a lump sum with a bank or Non-Banking Financial Company (NBFC) for a fixed tenure at a predetermined interest rate. Your principal and interest are guaranteed, making FDs ideal for conservative investors and those looking for predictable returns.

In India, deposits with scheduled commercial banks are insured by the Deposit Insurance and Credit Guarantee Corporation (DICGC) up to ₹5,00,000 per depositor per bank. This includes both principal and interest, providing an additional layer of safety.

How FD Interest Is Calculated

Most Indian banks compound FD interest on a quarterly basis. This means the interest earned every three months is added to the principal, and the next quarter's interest is calculated on this larger amount. Some banks offer monthly or half-yearly compounding.

With quarterly compounding, even a small deposit grows faster than simple interest because interest earns interest every three months.

Example Calculation

Suppose you invest ₹1,00,000 in an FD at 7.1% per annum for 5 years with quarterly compounding.

With simple interest, the same deposit would earn only ₹35,500 in interest (₹7,100 per year × 5 years). Quarterly compounding earns you an additional ~₹5,978 without any extra investment.

Cumulative vs Non-Cumulative FD

Banks offer two types of FD payout structures. Choosing the right one depends on whether you need regular income or want maximum returns at maturity.

• Cumulative FD — Interest is compounded and reinvested back into the deposit. You receive the full maturity amount (principal + compounded interest) at the end of the tenure. This option gives higher total returns and is ideal if you do not need regular income from the deposit.
• Non-Cumulative FD — Interest is paid out to you at regular intervals (monthly, quarterly, half-yearly, or yearly) instead of being reinvested. Your principal remains the same throughout the tenure. This option gives lower total returns but provides a steady income stream, suitable for retirees and those depending on interest income for monthly expenses.

TDS on FD Interest

Interest earned on Fixed Deposits is fully taxable in India. Banks deduct Tax Deducted at Source (TDS) if your total FD interest from a bank exceeds certain thresholds in a financial year:

• General depositors: TDS is deducted at 10% if interest exceeds ₹40,000 per year from a single bank.
• Senior citizens (60+): The threshold is higher at ₹50,000 per year.
• No PAN: If you have not provided your PAN to the bank, TDS is deducted at 20%.

Form 15G / 15H: If your total income is below the taxable limit, you can submit Form 15G (below 60 years) or Form 15H (senior citizens) to the bank at the start of each financial year to avoid TDS deduction. This does not exempt you from paying tax — you must still declare FD interest in your income tax return.

Note: This calculator shows pre-tax returns. Your actual returns may be lower depending on your tax slab.

How to Use This Calculator

1. Enter the deposit amount — the lump sum you plan to invest in the FD.
2. Enter the annual interest rate — the rate offered by your bank for the chosen tenure.
3. Enter the tenure — the number of years and months for which you want to lock in the deposit.
4. Select compounding frequency — quarterly is the standard for most Indian banks. Choose monthly, half-yearly, or yearly if your bank offers a different frequency.
5. Select payout type — choose Cumulative if you want interest reinvested for maximum returns, or Non-Cumulative if you want regular interest payouts.

Tips for Maximising FD Returns

• Compare rates across banks — interest rates vary significantly between public sector banks, private banks, small finance banks, and NBFCs. Small finance banks often offer 0.5–1% higher rates than large banks.
• Senior citizen advantage — most banks offer an additional 0.25–0.50% interest for depositors aged 60 and above. Some banks offer super senior citizen rates (80+) with even higher premiums.
• Tax-saver FD (Section 80C) — you can claim a deduction of up to ₹1,50,000 per year by investing in a tax-saver FD with a mandatory 5-year lock-in period. Note: the interest earned is still taxable.
• Laddering strategy — instead of putting all your money in a single FD, split it across multiple FDs with different tenures (1 year, 2 years, 3 years, etc.). This gives you regular liquidity while still earning competitive rates.
• Avoid premature withdrawal — breaking an FD before maturity typically attracts a penalty of 0.5–1% on the applicable interest rate, reducing your effective returns.
• Check the effective annual rate — an FD with quarterly compounding at 7% gives a higher effective return than one with yearly compounding at 7%. Always compare the effective annual yield.
