The Formula

Fixed Deposits use compound interest. Most banks compound quarterly. The formula is:

FD Maturity Amount:
A = P × (1 + r/n)n×t

Where:
P = Principal (deposit amount)
r = Annual interest rate (as decimal)
n = Compounding frequency per year (4 for quarterly)
t = Tenure in years

Example:
P = ₹5,00,000, r = 7.10%, n = 4 (quarterly), t = 3 years
A = 5,00,000 × (1 + 0.071/4)4×3
A = 5,00,000 × (1.01775)12
A = 5,00,000 × 1.2352 = ₹6,17,614
Interest earned = ₹1,17,614

TDS (Section 194A):
10% on interest above ₹40,000/year (₹50,000 for senior citizens)
20% if PAN not submitted

Senior Citizen Bonus:
+0.50% p.a. above general citizen rate at most banks

The key insight: quarterly compounding gives slightly higher returns than annual compounding. On a ₹5 lakh FD at 7.1% for 3 years, the compounding benefit is approximately ₹1,500–2,000 compared to simple interest.

Example

Priya — IT professional depositing ₹5 lakh FD at SBI

Priya is 32, earns ₹12 lakh/year, and wants to park ₹5 lakh in a 3-year FD at SBI at 7.10% quarterly compounding.

Step 1: Calculate maturity

Deposit₹5,00,000
Rate7.10% p.a.
Tenure3 years
CompoundingQuarterly
Maturity amount₹6,17,614
Interest earned₹1,17,614

Step 2: Tax impact

Annual interest (approx.)₹39,205
TDSNil (below ₹40,000 threshold)
Marginal slab (₹12L income, new regime)15%
Actual tax on interest₹5,881/year

Step 3: Post-tax return

3-year interest (pre-tax)₹1,17,614
Approx. tax (3 years)₹17,642
Post-tax interest₹99,972
Effective post-tax rate~6.03% p.a.

Priya earns ₹1,17,614 interest over 3 years, but after 15% tax, her effective return is about 6.03%. If she had put the same ₹5 lakh in PPF at 7.1%, the entire interest would be tax-free.

FAQ

As of March 2026, major bank FD rates for general citizens (1-3 year tenure) are: SBI: 6.50-7.25%, HDFC Bank: 7.00-7.50%, ICICI Bank: 6.90-7.25%. Small finance banks and NBFCs offer higher rates (8-9%) but carry slightly higher risk. Senior citizens get an additional 0.50% at most banks. Rates vary by tenure and deposit amount.
Yes. FD interest is fully taxable at your income tax slab rate. The bank deducts TDS at 10% if your annual interest exceeds ₹40,000 (₹50,000 for senior citizens). This TDS is not the final tax — it is adjusted against your actual tax liability when you file your ITR. If your total income is below the basic exemption limit, submit Form 15G (below 60 years) or Form 15H (60+) to the bank to avoid TDS deduction.
A tax-saving FD has a 5-year lock-in period and qualifies for deduction under Section 80C up to ₹1.5 lakh per year (Old Regime only). However, the interest earned is still taxable at your slab rate. This makes PPF a better option for many taxpayers because PPF interest is completely tax-free (EEE status) and also qualifies for 80C. Tax-saving FDs do not allow premature withdrawal or loan facility.
Most banks charge a penalty of 0.5% to 1% on the applicable interest rate for premature withdrawal. For example, if the FD rate is 7.10% and you break it early, the bank applies the rate for the actual period held, minus the penalty. Some banks waive the penalty for small FDs or senior citizens. Tax-saving FDs (5-year lock-in) cannot be withdrawn prematurely.
FDs in banks are insured by the Deposit Insurance and Credit Guarantee Corporation (DICGC), a subsidiary of RBI, up to ₹5 lakh per depositor per bank. This covers both principal and interest. If you have more than ₹5 lakh, consider spreading across multiple banks for full coverage. Corporate FDs (from NBFCs) are not covered by DICGC and carry higher risk.
