Compound Interest
In Simple Interest, interest is always on original principal. In Compound Interest, interest is added to principal every year (or period), and next year's interest is on new amount. CI gives more return than SI. CI = P(1+R/100)โฟ - P. More compounding periods = more interest earned.
