How does compound interest help your money grow over time?

Compound interest is like having money that earns money, and it grows faster over time.

Imagine you have a piggy bank where your allowance goes every week. If you put $10 in the piggy bank, and then next week, you get another $10, that’s simple adding up, right? But now imagine your piggy bank has magic coins (we’ll call them compound coins) that give you extra money just for keeping your savings there.

Let’s say you save $10 each week in a piggy bank with compound coins. After one month, the piggy bank gives you an extra $1 because of the coins, now you have $41 instead of just $40! The next month, the piggy bank gives you even more money from that extra $1, so it grows faster and faster.

It's like your savings is on a rollercoaster. At first, it moves slowly, but as time goes by, it picks up speed, and that’s all because of compound interest!
