    Compound interest is a mathematical principle that states that interest on a sum of money compounds over time. This means that the amount of interest that is earned on an initial investment is not the only thing that increases over time; the original principal also grows. This is why investments that have a high rate of compound interest are often more profitable than those with a low rate of interest.
