Compound Interest

What compound interest really means is when you borrow money from a bank and have to pay interest. Interest, is the extra money owed to the bank due to the fact that you borrowed money; like a fee. The concept of interest is so that the bank makes money in the process of letting you borrow it.

Suppose the starting principal was $100.00 and the annual growth rate was 10%, in three years the future value would be $133.00

The website below allows you to enter the annual rate, savings rate, and monthly contributions. After entering those amounts, it shows a graph and explains the interest rate.
