Bank Fixed Deposit Compounding Formula Explained
Most commercial banks compound FD interest on a quarterly basis (4 times a year). The maturity formula is A = P × (1 + r / 4)^(4 × t), where A is maturity amount, P is principal, r is annual interest rate in decimal, and t is tenure in years.
For senior citizens, banks typically offer an additional 0.50% interest rate premium. Tax-saving 5-year FDs qualify for Section 80C deductions up to ₹1.5 Lakh.
Worked FD Examples
Example: ₹1,00,000 FD at 7.0% for 5 Years (Quarterly Compounding)
- r = 0.07, compounding periods n = 4 × 5 = 20.
- Maturity A = 1,00,000 × (1 + 0.07/4)^20 = 1,00,000 × (1.0175)^20 = ₹1,41,478.
Interest Earned: ₹41,478 | Total Maturity Value: ₹1,41,478.
