How does compound interest affect long-term savings?

Compound interest is like having a piggy bank that grows bigger every year without you doing anything special.

Imagine you have $10 in your piggy bank. If it gets 10% interest each year, after one year, you’ll have $11, easy enough! But here’s the fun part: next year, that 10% is calculated on $11, not just $10. So now you get $1.10 in interest, and your piggy bank becomes $12.10.

This is called compound interest, it’s like your money is working overtime for you, making more money every year from the money it already made.

How It Works Over Time

Let’s say you keep adding $10 to your piggy bank each year. With compound interest, those extra dollars also start earning their own interest over time, just like how your piggy bank grows bigger and bigger, and it feels lighter in your hand because there's more inside!

After 20 years, that little $10 you started with could turn into something much bigger, maybe even enough for a new toy or a fun trip!
