Decision Rules

Decision Rules

Technique Accepting Criteria for Single or Independent Project(s) Accepting Criteria for Mutually Exclusive Projects
DPB Less than the Target Period Shortest Payback Period
ARR Above the Target Rate With the highest ARR
NPV A positive NPV With the highest positive NPV
IRR Higher than the Target Rate (Cost of Capital) With the highest IRR

In this table:

  • DPB stands for Discounted Payback Period, but if you're referring to the traditional method, it should be just "Payback Period" (PB).
  • ARR is Accounting Rate of Return.
  • NPV is Net Present Value.
  • IRR is Internal Rate of Return.

For Single or Independent Projects:

  • Payback Period (PB): The project is acceptable if its payback period is less than the target period set by the company.
  • ARR: A project is considered good if its ARR is above the company’s target rate.
  • NPV: Projects with a positive NPV should be accepted as they are expected to add value to the company.
  • IRR: If a project’s IRR exceeds the target rate or the company’s cost of capital, it is acceptable.

For Mutually Exclusive Projects (where you must choose one among several projects):

  • Payback Period: The project with the shortest payback period is preferred.
  • ARR: The project with the highest ARR is preferred.
  • NPV: Among competing projects, the one with the highest positive NPV is chosen because it is expected to add the most value.
  • IRR: The project with the highest IRR is preferred, provided the IRR is above the cost of capital.

This decision matrix allows companies to evaluate investment opportunities in a structured way to determine the best use of capital for maximized returns.
