value concepts: present value and future value. Looking at future value, the concept is that an amount in hand today will grow if it earns a specific rate of interest over a given period of time. This growth in value occurs not just because of the rate of interest being earned each year but also because that earned interest compounds. In other words, the interest earned in year one is added to the principal in year two, and interest is earned on this new principal balance; this continues through the set period of time. Work through the following scenario to understand future value and the concept of compounding interest. You have an eccentric aunt who has promised to deposit $7,500 in a savings account in your name. She has stated that you will not have access to the money for four years but that the money will be earning 5% interest. At the designated future date, the principal and interest will be yours to purchase a new car. First gather the relevant data by completing the following table. Present Value: $ Period: years Rate of Interest: % Next use either the table of future value factors, your financial calculator, or the future value formula to calculate the future value of this money in four years.
