Why Compound Interest Matters

Compound interest is often called the “eighth wonder of the world” because it allows your money to grow exponentially rather than linearly. Instead of earning interest only on your initial investment, you also earn interest on previously earned interest.

Over time, this creates a powerful snowball effect that significantly increases your total wealth.
