What Is Interest? Teaching Kids How Money Grows Over Time
Most kids understand that when they save money, they have it available for later. But what if their money could grow on its own, just by sitting in a bank account? That’s where interest comes in!
Teaching kids about interest early helps them:
✔ Understand how saving money today leads to more money tomorrow
✔ Learn the power of smart financial decisions
✔ Get excited about growing their savings
✔ Avoid mistakes with debt and loans in the future
So, let’s break it down in a fun and simple way so kids can start making smart money choices!
What Is Interest? A Kid-Friendly Explanation
💰 Interest is extra money that a bank or financial institution gives you for saving your money with them. It’s like a reward for keeping your money in a safe place.
Think of it like planting a seed. If you take care of it and give it time, it grows into a tree. Interest works the same way—the longer you save money, the more it grows!
Example:
If you put $100 in the bank and the bank offers 5% interest per year, at the end of the year, you’ll have $105—without doing anything!
The Two Types of Interest: Simple vs. Compound
Not all interest works the same way. There are two main types of interest:
1. Simple Interest
Simple interest means you earn money only on your original amount (the principal).
📊 Formula:
Simple Interest = Principal × Interest Rate × Time
🔹 Example: If you save $100 at 5% interest per year, after 3 years, you would have:
$100 + ($100 × 5% × 3) = $115
That means you earned $15 in total!
2. Compound Interest (The Magic of Money Growth!)
Compound interest is even better because it lets your money grow on top of itself! You earn interest not just on your original savings but also on the interest you’ve already earned.
📊 Formula:
Compound Interest = Principal × (1 + Interest Rate) ^ Time
🔹 Example: If you save $100 at 5% interest per year, but this time it compounds, after 3 years, you would have:
$100 × (1.05)^3 = $115.76
That’s more money than simple interest because the interest is building on top of itself!
Why Compound Interest Is So Powerful
🔹 The earlier you start saving, the more money you will have in the future!
Let’s compare two kids who both save money:
Alex started earlier and ended up with MORE money! That’s the magic of compound interest—time matters!
