  • What is compound interest?

    Compound interest can be thought of as "interest on interest". It will make a sum grow faster than simple interest, which is calculated only on the original "("principal") amount. How fast interest will compound depends on how often interest is "reinvested" with the principal. The more the number of compounding periods, the greater the amount of compound interest.
