Compound interest is a smart and easy way to get rich. Although it takes a long time, the outcome is rewarding. The dictionary describes defines compound interest as: "Interest paid both on principal and on interest earned during previous compounding periods. Essentially, compounding involves adding interest to the sum of principal and any previous interest in order to calculate interest in the next period". To me, compound interest is pretty much the way one amount of money receives interest (interest is a small percentage of an amount of money that you deposit into a bank, and for keeping your money in the bank, they pay you interest. Interest is usually anywhere between 0.1-30%.

The average is about 1.5-6 % interest a year.), and then after a year receives the same percentage of interest but on the already accumulated amount of money. (the amount that has already gotten interest added on the year before). This goes on until the money is taken out, or the interest rate is changed, or any other disruptions change the banks systems. Bank breaks down etc.

Compound Interest works in a fairly simply and very systematic way. Lets say Bob puts $100.00 in the bank. The interest rate is 4% a year.(4% of the $100) After one year, Bob looks back at his amount of money, and suddenly he has $104.00. This is because after one year he has collected his interest. Because his interest rate was 4%, he collects 4% of his original $100. 4% of $100.00 is 4, because [4/100= 0.04, 100%= 4(amount/total*100%)]...
