How is Simple Interest Calculated?

Simple Interest (SI) is calculated using the formula:

SI = (Principal × Rate × Time) / 100

Example:
If you invest ₹10,000 at 5% interest for 3 years:
SI = (10,000 × 5 × 3) / 100 = ₹1,500

How is Compound Interest Calculated?

CI = P × (1 + R/n)n×T - P

Example:
If you invest ₹10,000 at 5% annual interest compounded annually for 3 years:
CI = 10,000 × (1 + 5/100)3 - 10,000 = ₹1,576.25
