⨠What Is Compound Interest? (Simple Explanation)
Compound interest is the interest you earn on your initial amount + the interest accumulated so far.
In short:
Your money makes more money â and that new money also earns money.
This creates an exponential growth effect.
For example:
If you invest $1,000 at 10% interest, you donât just earn $100 every year.
You earn interest on the new balance each year, making your returns increase automatically.
This is why compound interest is often called âthe 8th wonder of the world.â
