How FD interest is calculated, comparison of compound vs simple interest, and tips to maximize FD returns in India.
Fixed Deposits in India: Complete Returns Guide for 2026
A Fixed Deposit (FD) is the safest investment instrument in India after government schemes. Your capital is guaranteed by the bank, and returns are locked in at the time of opening the FD. This guide covers everything you need to maximise your FD returns.
How FD Interest Is Calculated
Banks compound FD interest quarterly by default (unless specified otherwise in the product terms).
Compound Interest Formula:
A = P × (1 + r/n)^(n×t)
Where:
- A = Maturity amount
- P = Principal amount
- r = Annual interest rate (decimal)
- n = Compounding frequency per year (4 for quarterly)
- t = Time in years
Example: ₹5 lakh FD at 7.5% for 2 years, compounded quarterly:
A = 5,00,000 × (1 + 0.075/4)^(4×2)
A = 5,00,000 × (1.01875)^8
A = 5,00,000 × 1.16084
Maturity = ₹5,80,420 (Interest earned: ₹80,420)

RBI DICGC insurance: All bank deposits up to ₹5 lakh per depositor per bank are insured. Small Finance Banks carry marginally higher risk but offer higher rates and are fully DICGC-insured.
Tax on FD Interest: Everything You Need to Know
FD interest is fully taxable at your income slab rate — it is added to your "Income from Other Sources".
TDS (Tax Deducted at Source):
- 10% TDS if FD interest exceeds ₹40,000/year (₹50,000 for senior citizens)
- 20% TDS if PAN is not provided to the bank
- TDS is not the final tax — you pay more if you're in a higher bracket
Important: Even if your FD interest is below ₹40,000 and no TDS is deducted, you must declare it in your ITR and pay applicable tax.
Form 15G/15H (to avoid TDS deduction):
- 15G: For individuals below 60 whose total taxable income is below ₹2.5 lakh
- 15H: For senior citizens (60+) whose total taxable income is below ₹3 lakh
- Submit at the start of every financial year to each bank branch
FD vs Other Fixed-Income Options: Return Comparison
| Instrument | Rate (2026) | Tax Treatment | Liquidity | Risk |
|---|---|---|---|---|
| Bank FD (top) | 7.75–9.0% | Taxable at slab | Premature with penalty | DICGC insured |
| Post Office FD | 6.9–7.5% | Taxable (5yr FD: 80C) | Limited | Sovereign guarantee |
| NSC | 7.7% | Taxable (80C deduction) | No premature | Sovereign guarantee |
| Senior Citizen Savings Scheme | 8.2% | Taxable | Partial withdrawal after 1 yr | Sovereign guarantee |
| RBI Floating Rate Bond | 8.05% | Taxable | Only after 7 years | Sovereign guarantee |
| Debt Mutual Fund (3yr) | 7–8% | Slab rate (post Apr 2023) | High | Market risk (low) |
| Arbitrage Fund | 7–8% | STCG 20%/LTCG 12.5% | High | Very low |
Tax efficiency note: For investors in the 30% tax bracket, the post-tax return on a 7.5% FD is only 5.25%. Debt mutual funds offer similar returns with the benefit of indexation (for pre-April 2023 investments) and better liquidity.
FD Ladder Strategy: Maximising Returns and Liquidity
Instead of putting ₹10 lakh in a single 3-year FD, split it:
- ₹2.5 lakh in 1-year FD
- ₹2.5 lakh in 2-year FD
- ₹2.5 lakh in 3-year FD
- ₹2.5 lakh in 5-year FD
Benefits:
Premature Withdrawal Penalty
If you break an FD before maturity:
- Most banks charge 0.5–1% below the applicable rate for the completed tenure
- Example: You booked at 7.5% for 3 years, break after 1 year. Bank pays 6.5% (7% applicable 1-year rate, minus 0.5% penalty)
- Some banks offer "sweep-in FDs" that automatically break in units as needed without penalty
