How Compound Interest Works
Compound interest is the key factor behind investment growth. It means earning interest on both your initial investment and previously earned interest.
For example:
- In the first year, you earn interest on your initial amount.
- In the second year, you earn interest on both your initial amount and the first year’s interest.
Over time, this creates exponential growth, especially when combined with monthly contributions.
