How Does Compound Interest Work?
Compound interest means you earn “interest on interest.” Unlike simple interest, which only applies to the original amount, compound interest adds your earnings back to your balance, allowing your money to grow exponentially.
For example:
If you invest $1,000 at 10% annual interest, after 1 year you have $1,100.
With compounding, the next year you earn interest on $1,100, not just $1,000.
Over decades, this snowball effect can turn small investments into large sums.
According to Investopedia, compound interest is often called the “eighth wonder of the world” because of its wealth-building potential.
