Future Value and Compound Interest

What is Compound Interest and Future Value?

Compound interest is calculated on the initial amount borrowed or invested plus any interest that is either charged or earned respectively. We use the compound interest formula to calculate the future value of the loan or investment. The following post will focus on the following:
