How to Calculate Fixed Deposit Returns
- Enter the principal amount you wish to invest
- Enter the FD interest rate offered by your bank
- Select compounding frequency (quarterly for most Indian banks)
- Enter the tenure in years
- Click Calculate to see maturity amount, interest earned, and effective annual yield
How FD Calculator is Calculated
FD Maturity = P × (1 + r/n)(n×t), where P = principal, r = annual interest rate, n = compounding frequency per year (4 for quarterly, the Indian bank standard), t = tenure in years.
Worked Example
₹5,00,000 FD at 7.0% for 5 years (quarterly compounding): Maturity = ₹5,00,000 × (1 + 0.07/4)^20 = ₹7,07,161. Interest earned = ₹2,07,161.
Common Use Cases
- Comparing FD rates across banks
- Tax planning for FD interest (TDS)
- Senior citizen FD rate comparison
- Emergency fund investment planning
Common Mistakes to Avoid
- Ignoring TDS on FD interest — banks deduct 10% TDS if annual interest exceeds ₹40,000 (₹50,000 for senior citizens). Submit Form 15G/15H to avoid TDS if you are in the nil tax bracket.
- Not checking if the rate is for cumulative or non-cumulative FD — interest payout FDs have slightly lower effective yield.
- Assuming FD returns beat inflation — at 7% FD rate and 6% inflation, your real return is only ~1% per year.
- Breaking an FD early without checking penalty — most banks charge a 0.5–1% penalty on premature withdrawal.

Formula & Methodology
Maturity = P × (1 + r/n)^(n×t) for cumulative FD. For non-cumulative: Interest per period = P × r/n. Where P = Principal, r = Annual rate, n = Compounding frequency, t = Years.
Step-by-Step Example
FD of ₹10,00,000 at 7.5% for 5 years, quarterly compounding: Maturity = 10,00,000 × (1 + 0.075/4)^(4×5) = 10,00,000 × (1.01875)^20 = ₹14,48,502. Interest = ₹4,48,502.
