Why use NPV

1
Why use NPV?

• NPV approach is considered the best one for
  evaluating capital budgeting.
• NPV is easy to interpret and understand
• Positive NPV projects are accepted, negative NPV
  projects are rejected
• Accepting positive NPV projects benefits the
  stockholders.
• Three key attributes
• NPV uses cash flows
• NPV uses all the cash flows of the project
• NPV discounts the cash flows properly

NPV is used as a benchmark for evaluating other
alternative approaches to capital budgeting.

Managerial perspective - PBP

• Payback rule is often used by large companies
  when making relatively small investment
  decisions.
• Used for decisions made by lower-level
  management.
• Its simple to use and allows upper management to
  delegate responsibility.
• Important in terms of management control (short
  term verification of managers assessment of cash
  flows).
• For bigger investment decisions, the payback rule
  is seldom used (when questions of controlling and
  evaluating the manager become less important than
  making the right investment decision).

Internal rate of return (IRR)

• The IRR is very similar to the NPV approach.
• Basic rationale it tries to find a single number
  that summarizes the merits of a project.
• That number does not depend on the interest rate
  that prevails in the capital market.
• The number is internal or intrinsic to the
  project and does not depend on anything except
  the cash flows of the project.

IRR

• IRR rules
• The firm should accept the project if the
  discount rate is below 10 (IRR discount rate).
  
• The firms should reject the project if the
  discount rate is above 10 (IRR

Advantages of the IRR

• Rule that summarizes the information about a
  project in a single rate of return.
• Simple way of discussing a project.
• However, in order to apply the IRR, you must
  compare it with r. So, the discount rate is
  needed for making a decision under both
  approaches.
