Selecting a Discount Rate or MARR

  • Rosalie T. Ruegg
  • Harold E. Marshall


The discount rate, or MARR,1 imposes a condition of minimum profitability which a project or project increment must meet to qualify for acceptance. Because it affects whether a project will be accepted or rejected and how much will be spent on it, the value of the discount rate is a key ingredient in an economic evaluation. If it is set too high, some projects which are economic will be rejected; if too low, some projects which are uneconomic will be accepted.
