All rights reserved. 4-3 1 Calculating Interest Rates • Simple Interest – – – – Interest earned on the principle in one year’s time. Time is worth money A dollar today is worth more than a dollar in the future A dollar due in the future is worth less than a dollar today Interest earned = principal × rate × time (in years) Copyright © 2009 Pearson Addison-Wesley. All rights reserved. 4-4 Calculating Interest Rates (Cont.) • Compound Interest – Interest that accumulates during a year is added to the principal at year’s end, thereby earning more interest in the following year – Banks automatically add interest earned to the principle at specified time intervals – Future Value [FV]—amount today’s principle will be worth in “n” years after adding compounded interest of rate “r”. FV = principle(PV) × (1 + r)n Copyright © 2009 Pearson Addison-Wesley. All rights reserved. 4-5 Calculating Interest Rates (Cont.) • Compound Interest (Cont.) – Present Value [PV]—amount a future sum of money in “n” years will be worth today after discounting back to the present at rate “r” Future value/(1 + r)n = present value Copyright © 2009 Pearson .
