Time value of money (TVM)
Time-value-of-money (TVM) calculations make use of the
notion that a dollar today will be worth more than a dollar
sometime in the future. A dollar today can be invested at
a certain interest rate and generate a return that the same
dollar in the future cannot. This TVM principle underlies
the notion of interest rates, compound interest, and rates
of return.
