The present value of a single amount is the discounted value for one future payment, whereas the present value of an annuity represents the discounted value of a series of consecutive payments of equal amount why does money have a time value? Money has a time value because funds received today can be reinvested to reach a greater value in the future. a person would rather receive $1 today than I in ten years, because a dollar received today, invested at 6 percent, is worth $.791 after ten years Does inflation have anything to do with making a dollar today worth more than a dollar tomorrow? Inflation makes a dollar tod ay worth more than a dollar in the future. Because inflation tends to erode the purchasing power of money, funds received today will be worth more than the same amount received in the future S-305 Copyright C2005 by The McGra-Hill Companies, Inc
