Simple vs. Compound Interest

#### Simple vs. Compound Interest

One of the key concepts in personal finance, is the difference between simple and compound interest. If you’re just starting to learn about saving, investing, or just want to understand your bank statement a bit better, then this is important to understand.

Let’s kick things off with a basic question: why does interest matter? Imagine you’re lending your friend \$100, and they promise to give it back with an extra \$10 as a thank-you for letting them borrow it. That extra \$10 is interest. Now, there are two ways interest can be calculated – simple and compound.

First up, let’s discuss simple interest. As the name suggests, it’s pretty straightforward. Let’s say you put your money in a savings account that offers a 5% annual interest rate. If you start with \$100, after one year, you’ll earn \$5 in interest. So, at the end of the year, you’d have \$105. If you keep that money in for another year, you’d earn another \$5, making it \$110. Simple, right? The interest you earn is always based on the original amount.

But now, let’s shift gears to compound interest. This is where the magic happens, especially if you’re thinking of long-term investments. Going back to our previous example, let’s say your \$100 is in an account that compounds interest annually at the same rate of 5%. The first year is the same; you’d earn \$5 in interest. But here’s the twist: in the second year, you’re not just earning interest on your original \$100, but also on the \$5 interest from the first year. So, instead of just another \$5, you’d earn \$5.25, making your total \$110.25. Might not seem like a big difference now, but over time, it really adds up.

Think of compound interest like a snowball rolling down a hill. As it rolls, it picks up more snow and gets bigger and bigger. The longer it rolls, the faster it grows. That’s the power of compound interest. If you’re starting to save or invest at a young age, even small contributions can turn into significant amounts over time because of this effect.

So, which one’s better? From an earning standpoint, compound interest is the clear winner. However, remember, when it comes to debts and loans, you’d ideally want them to have simple interest. Compound interest on debts can make them grow just as quickly, which isn’t something you’d want.

So understanding the difference between simple and compound interest is important. Not only does it help you make informed decisions about saving and investing, but it also gives you a clearer picture of how your money is working for you. Remember, time can be your greatest ally when it comes to compound interest.
