Today, there’s a really helpful thing called the Rule of 72. It’s great for everyone, if you’re new to money stuff or you know a lot.
This article explains the Rule of 72, breaks down how it works, and gives real examples to show why it’s important.
What’s the Rule of 72
The Rule of 72 is like a quick trick that helps you guess when your money will double. You guess by using a fixed yearly interest rate. It’s a super easy way to see how your money can grow without doing hard math.
The Rule of 72 is easy to understand. You do a simple math thing –
Years to Double = 72 / Annual Interest Rate
You put the interest rate in the math, and it tells you about how many years it’ll take for your money to double.
The Rule of 72 is all about the magic of making money grow. This guy named Albert Einstein thought this money-growing thing was amazing. The Rule of 72 shows how your money can get bigger and bigger over time.
Example 1 – Imagine you have money that gets 8% interest every year. With the Rule of 72, you can guess that your money will double in about 9 years (72 / 8). This means in around 10 years, your money might become two times bigger, all because of the magic of growing money.
Example 2 – Now think about money that gets more interest, like 12% every year. With the Rule of 72, your money could double in only 6 years (72 / 12). See how faster-growing money takes less time to double?
When It Works and When It Doesn’t
The Rule of 72 is awesome, but it’s not perfect for everything. It works best when your yearly interest rate is pretty much the same all the time. But real money can change, so the Rule of 72 gives an estimate, not an exact answer.
Example 3 – Imagine an investment that gives you different interest rates, like between 5% and 10% each year. With the Rule of 72, your money might double in around 14.4 years (72 / 5) to 7.2 years (72 / 10). This rule gives you a range, not just one number.
