💡 FD Interest is Taxable
FD interest is added to your income and taxed at your slab rate. For 30% bracket investors, post-tax returns on FDs are lower than tax-free or ELSS mutual fund returns.
How the FD Calculator Works
Your deposit amount is compounded at the bank's quoted annual interest rate, using the compounding frequency banks actually use (usually quarterly), for your chosen tenure — giving you the exact maturity amount and total interest earned.
Example Scenarios
| Scenario | Result |
|---|---|
| ₹1,00,000 for 5 years at 7% (quarterly) | Maturity ≈ ₹1.41 lakh |
| ₹5,00,000 for 3 years at 7.25% | Maturity ≈ ₹6.20 lakh |
| ₹10,00,000 for 10 years at 6.5% | Maturity ≈ ₹19.06 lakh |

Frequently Asked Questions
Fixed deposit maturity is calculated using compound interest: A = P × (1 + r/n)^(n×t), where P is the principal, r is the annual interest rate, n is the compounding frequency (usually quarterly for Indian bank FDs), and t is the tenure in years.
Yes, FD interest is fully taxable at your income tax slab rate and is added to your total taxable income. Banks also deduct TDS at 10% if interest exceeds ₹40,000/year (₹50,000 for senior citizens) in a financial year.
Small finance banks typically offer the highest FD rates (7.5-8.5%), followed by private banks (6.5-7.5%) and public sector banks (6-7.25%). Senior citizens usually get an additional 0.25-0.5% over standard rates. Check TopFund's FD rate comparison page for current rates across banks.
Common Mistakes to Avoid
- Not comparing compounding frequency across banks — quarterly vs monthly compounding changes the effective yield.
- Ignoring TDS deduction at 10% once interest crosses ₹40,000/year (₹50,000 for senior citizens).
- Locking a large sum into a single long-tenure FD instead of laddering across maturities for liquidity.
