About Compound Interest

Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is earned on the principal sum plus previously accumulated interest.

Albert Einstein is said to have described compound interest as "the eighth wonder of the world." The power of compound interest is that it allows your money to work for you, and the earlier you start investing, the more time your money has to grow.
