Time value of money techniques can be used to determine whether an investment's return is satisfactory given the investment's cost.
Ignoring risk at this point, a satisfactory investment would be one for which the present value of benefits (discounted at the appropriate discount rate) equals or exceeds its cost.
The three possible cost-benefit relationships and their interpretations follow:
1. If the present value of the benefits equals the cost, you would earn a rate of return equal to the discount rate.
2. If the present value of benefits exceeds the cost, you would earn a rate of return greater than the discount rate.
3. If the present value of benefits is less than the cost, you would earn a rate of return less than the discount rate.
You would prefer only those investments for which the present value of benefits equals or exceeds its cost - situations 1 and 2.
In these cases, the rate of return would be equal to or greater than the discount rate.
