How Simple Interest Works
Simple interest is calculated using the formula SI = P × R × T, where P is principal, R is annual interest rate, and T is time in years. The interest amount stays the same each period because it's calculated only on the original principal.
SI = P × R × T / 100
Total Amount = P + SI
Total Amount = P + SI
Example
₹50,000 at 6% for 3 years:
SI = 50000 × 6 × 3 / 100 = ₹9,000
Total = ₹59,000
