How Compound Interest Works

Compound interest works by continuously adding earned interest back to the original investment. Over time, this creates exponential growth.For example:If you invest ₹10,000 at 10% annual interest:Year 1 → ₹11,000 Year 2 → ₹12,100 Year 3 → ₹13,310Notice how the interest keeps increasing every year because it is calculated on the growing balance.This is the core power of compounding: The longer you stay invested, the faster your wealth grows.
