The marginal rate of return is a term that is used to identify the rate of return that is generated if a single unit is added to the current process, in comparison with choosing to maintain the status quo or taking some other type of action that exerts some effect on the returns realized.
Therefore, some reasonable rate must be established for the selection criteria (step 4) of the engineering economy study ( Figure 1â1 ). The Minimum Attractive Rate of Return (MARR) is a reasonable rate of return established for the evaluation and selection of alternatives. A project is not economically viable unless it is expected to return at least the MARR. MARR is also referred to as the hurdle rate, cutoff rate, benchmark rate, and minimum acceptable rate of return. Figure 1â12 indicates the relations between different rate of return values. In the United States, the current U.S. Treasury Bill return is sometimes used as the benchmark safe rate.
