How time and compound interest work together to grow money

Have you ever heard the saying, "Make your money work for you"? That is exactly what compound interest does. And the sooner you start saving, the harder it works for you!

Compound interest is often called "interest on interest." It means you earn interest not only on the money you saved, but also on the interest you've already earned.

A simple example

Imagine you save $100 in a bank account that pays 10% interest each year.

  • Year 1: You earn $10 in interest - You now have $110. 

  • Year 2: You earn 10% on $110, not just the original $100 - You earn $11 - You now have $121. 

  • Year 3: You earn 10% on $121 - You earn $12.10 - You now have $133.10. 

Each year, your money grows a little faster because you're earning interest on your previous interest.

Why it's important to start saving as soon as possible?

The biggest advantage of compound interest is time.

The earlier you start saving, the more time your money has to grow. Even small amounts saved regularly can become much larger over many years.

For example, saving $20 a week may not seem like much today, but over time those savings, plus the interest they earn, can really add up. After 1 year you have earned $54.78 interest; after 10 years you have earned $7, 443 interest!

The bottom line

Compound interest is like planting a tree. At first, it grows slowly. But as it gets bigger, it grows faster and stronger.

The same happens with your money. The more time you give it, the more opportunity it has to grow.

Remember: It's not about saving huge amounts. It's about starting early, saving regularly, and letting time do the hard work.
