MGT 470 Ch 4 TVM (cs3ed) v1.0 Aug 15 1 Ch 4: Time Value of Money Time Has Value (The Time Value of Money – TVM):  Time affects the value of financial assets and transactions  When money is some how invested (and not just placed under a mattress or in a safe), the amount of money grows  Although money loses value over time due to inflation, the amount of money in an account that earns a positive ROR will be greater in the future than what it is today. Why is this true?  Thus the money in the account has different values at different points in time  This is what the term “Time Value of Money” refers to  The ROR should compensate for opportunity cost, inflation and risk  the increasing amount of money over time should more than make up for the value lost due to inflation and opportunity costs
