A Fixed Deposit (FD) is one of India's most popular savings instruments. You deposit a lump sum for a fixed tenure at a pre-agreed interest rate, and the bank guarantees your principal plus interest at maturity. FDs are insured by the Deposit Insurance and Credit Guarantee Corporation (DICGC) up to ₹5 lakh per depositor per bank, making them one of the safest investments.
Indian banks compound FD interest quarterly by default, though some offer monthly interest payouts for senior citizens or cumulative (compounding) options. Our FD calculator uses the formula A = P × (1 + r/n)^(nt), where n is the compounding frequency. You can choose monthly, quarterly, half-yearly, or annual compounding to compare returns. The effective annual rate with quarterly compounding is slightly higher than the nominal rate — for example, a 7% nominal rate with quarterly compounding yields an effective rate of 7.19%.
FD interest rates vary by bank, tenure, and depositor category. Senior citizens (60+) typically receive 0.25–0.75% higher rates. Small finance banks often offer 8–9% on FDs. Tax-saving FDs (5-year lock-in) qualify for Section 80C deduction up to ₹1.5 lakh but are taxed on maturity. FD interest is added to your income and taxed at your slab rate, which reduces net returns for high-income earners.

Common use cases
- A retiree wants to park ₹10 lakh in an FD and needs to know the quarterly interest payout for living expenses.
- A salaried person is comparing a 6-month FD at 6.5% with a 1-year FD at 7.25% to determine the better effective annual return.
- Someone is comparing three bank FD rates (6.8%, 7.2%, 8.5%) across a large bank, a mid-size bank, and a small finance bank.
- A parent is opening a 3-year FD to fund their child's school fees — calculating the exact maturity amount and selecting the right tenure.
- A senior citizen is checking the additional maturity amount they earn due to the 0.5% senior citizen premium over 5 years.
Tips for best results
- 1Ladder your FDs instead of putting everything into a single tenure. Open FDs for 1, 2, and 3 years so you have one maturing every year, maintaining liquidity.
- 2Compare small finance banks (8–9%) and corporate FDs (rated AA+) alongside large banks. DICGC cover applies up to ₹5 lakh per bank.
- 3For amounts over ₹40,000/year in interest, TDS at 10% is deducted. If your total income is below the taxable limit, submit Form 15G (15H for seniors) to avoid TDS.
- 4Invest in a tax-saving 5-year FD (80C deduction up to ₹1.5L) only if you are in the 20% or lower tax slab — above that, ELSS mutual funds with a 3-year lock-in typically offer better post-tax returns.
- 5Re-invest maturity proceeds immediately. A one-week gap between FD cycles costs you several hundred rupees in interest at ₹10 lakh+ levels.
Frequently asked questions
- Is Konnect2Tools free?
- Yes. These in-browser tools are completely free to use with no account required for core functionality.
- Do my files leave my device?
- Browser document operations run locally, except where the operation uses an external service, such as AI summarisation. Read the processing note before using sensitive inputs.
- Is the FD Calculator tool safe to use?
- Local operations process document content on your device. External-service operations may send inputs as described in the processing note. Keep originals and inspect the output.
- Can I break an FD before maturity?
- Yes, premature withdrawal is allowed at most banks, but a penalty of 0.5–1% is charged on the interest rate. The final interest is calculated at the rate applicable for the actual period held, minus the penalty.
- Is FD interest fully taxable?
- FD interest is added to your total income and taxed at your applicable slab rate (5%, 20%, or 30%). If you are in the 30% slab, the post-tax return on a 7% FD is only 4.9%. High-income earners often prefer debt mutual funds or tax-free bonds for better post-tax returns.
- What is the safest FD option?
- FDs in public sector banks (SBI, PNB, Bank of Baroda) are considered the safest as they are government-backed. Private banks and small finance banks offer higher rates but carry marginally higher risk. DICGC insurance covers up to ₹5 lakh regardless.
- What is a sweep-in FD?
- A sweep-in FD links your savings account to an FD. Excess funds above a set threshold are automatically moved to an FD to earn higher interest. When you spend, funds sweep back to your account. This combines liquidity with FD returns.
