What is simple interest?

Simple interest is a method of calculating interest as opposed to compound interest. In interest calculation, compound interest is a method in which interest is carried over to the principal at regular intervals and calculated as a new principal, while simple interest is a method in which interest is calculated simply by multiplying a period by an interest rate. In other words, for simple interest, interest = principal x interest rate x period.
