Factors That Affect the Time Value of Money
Factors that Affect the Time Value of Money Time value of money is the concept that an amount of money in one’s possession is worth more than that same amount of money promised in the future (Garrison, 2006). The reason for this is that money today can be invested to earn interest and therefore will be worth more in the future (Brealey, Myers, & Marcus, 2004). This paper will explain how annuities affect time value
