What is interest?

Interest is an incredibly powerful concept, and can work to your benefit or detriment. If you have money and are saving money, a bank may pay you interest on your money in exchange for letting the bank hold on to it for you. On the other hand, if you need to borrow money, or use a credit card, a bank will charge you interest to do so.

What does compound interest mean?

Compound interest is a powerful economic force in which your money gains interest, and then more interest on the interest. So, you start making money on money that was paid to you on your initial deposit. Consider this example:

The interest rate is 5%.
You earn $25 in 1 year. This brings your total to $525.
In Year 2, you start with $525. The interest rate is 5%.
You earn $26.25. This brings your total to $551.25.
In the 10th year, you start with $756. The interest rate is 5%.
At the end of the year, you have $814.45. That is a total gain of $314.45.
