FD Calculator – Calculate Your Fixed Deposit Returns Instantly

What is a Fixed Deposit (FD)?

A Fixed Deposit (FD) is one of the safest and most popular investment options in India. Offered by banks, post offices, and NBFCs, an FD allows you to deposit a lump sum amount for a fixed period at a predetermined interest rate. Unlike a savings account, the interest rate on an FD is locked in for the entire tenure, giving you guaranteed returns regardless of market conditions.

Fixed Deposits are ideal for conservative investors who want capital protection and steady returns. They are backed by deposit insurance of up to ₹5 lakh per depositor per bank under DICGC, making them one of the safest investment instruments available in India.

FD Interest Calculation Formula

Fixed Deposit returns are calculated using the compound interest formula:

A = P × (1 + r/n)^(n×t)

Where A = Maturity amount, P = Principal amount, r = Annual interest rate (in decimal), n = Number of times interest is compounded per year, and t = Tenure in years.

Types of Fixed Deposits in India

1. Cumulative FD

Interest is compounded and reinvested. You receive the principal along with all accumulated interest at maturity. Ideal for long-term goals.

2. Non-Cumulative FD

Interest is paid out at regular intervals — monthly, quarterly, half-yearly, or annually. Suitable for retirees or those needing regular income.

3. Tax-Saving FD

5-year lock-in period. Qualifies for deduction under Section 80C up to ₹1.5 lakh per year. However, interest earned is fully taxable.

4. Senior Citizen FD

Most banks offer an additional 0.25% to 0.50% interest rate to senior citizens (aged 60+). Higher TDS exemption threshold of ₹50,000 per year.

Tips to Maximise Your FD Returns

• Choose quarterly compounding over annual compounding for higher effective yield
• Ladder your FDs across different tenures to balance liquidity and returns
• Senior citizens should always book FDs under their name for the extra interest rate benefit
• Compare rates across banks and small finance banks before booking
• Submit Form 15G/15H to avoid TDS deduction if your income is below the taxable limit
