How Compound Interest Works
Compound interest is the key factor behind investment growth. It means you earn interest not only on your initial investment but also on the accumulated interest over time.
For example:

- Year 2: Interest earned on initial + previous interest
- Year 3: Growth continues exponentially
This snowball effect is what makes long-term investing powerful.
