Imagine you have a piggy bank that gives you extra coins every time you add new ones.
Compound interest is like that piggy bank, it lets your money grow faster because you earn more from the money you already have.
How It Works
Let’s say you start with 10 cookies in your piggy bank (that's your starting money). If you put in 2 more cookies every week, and your piggy bank gives you 1 extra cookie for every 10 cookies you have, things get interesting.
At first, you only have a few more cookies. But after a while, the number of cookies you earn each time gets bigger because your piggy bank has more to work with. That means you’ll end up with way more cookies than just adding 2 every week, it’s like your cookies are helping you make more cookies!
Why It's Cool
It’s not magic, it’s just a smart way of growing money (or cookies). The longer you let it work, the more it helps. So even if you start small, over time, compound interest can turn your little piggy bank into a cookie mountain!
Examples
- Imagine you have $100 in a bank that gives 10% interest every year. After one year, you’ll have $110. Next year, the interest is calculated on $110, so you get $11 more, total becomes $121.
- If you save money and earn interest each year, your savings grow faster over time because you're earning interest on your interest.
- Putting money in a piggy bank that gives 5% interest every year means the amount keeps increasing with each passing year.
