An Interesting Look at Compounding

Now you know all about compound interest and how great it is, but how does it really compare to other kinds of interest?

Well, take a look at the chart above: It shows what you can expect from a $10 investment over 40 years with compound interest vs. simple interest.

Since we're talking stocks, we'll assume our $10 returned an average of eight percent per year. Can you guess which line is which?

If you guessed that compound interest is the blue line, you're spot on. As you can see, the two lines are pretty close at the beginning of the chart, but before long compound interest starts to pull away faster than a Ferrari at a green light.

In our example, simple interest takes your $10 and grows to $42. Not bad... until you see what compound interest does. After 40 years, your $10 is now worth $217.

Simple interest gives you a fixed amount of interest based on the amount of money you have at the beginning.

Compound interest, on the other hand, pays you the same interest rate but on the principal and the interest you've earned.

In other words, compounding pays you according to what you have now, not what you had when you started.

Doesn't sound like a big deal, does it? And that doubling penny from the lesson didn't either — until you saw how much cash you ended up with after a month.

Compound interest is one of those things that may not be easy to wrap your head around, but seeing the chart will likely give you a better idea of how it works and why Einstein thought it was so astounding.

It's also good to keep in mind how time plays a factor: the more time you give compound interest to work, the more money it'll make you. That's why getting your money to work for you as quickly as possible is so important.

Now go out there and get your compounding on.
