Compound Interest Interest that accrues on the initial principal and the accumulated interest of a principal deposit, loan or debt. Compounding allows a principal amount to grow at a faster rate than simple interest, which is calculated as a percentage of the principal amount. Investopedia Says: The more frequently interest is added to the principal, the faster the principal grows and the higher the compound interest will be. The frequency at which the interest is compounded is established at the initial stages of securing the loan. Generally, interest tends to be calculated on an annual basis although other terms may be established at the time of the loan.
