NPV Vs IRR

The net present value (NPV) and the internal rate of return (IRR) are techniques that can both be used by financial institutions or individuals when making major investment decisions. Each method has its own strengths and weaknesses. However, the net present value method comes out on top, and here’s why:

When dealing with independent projects, both NPV and IRR will yield the same investment decisions. Independent, in this context means that the decision to invest in one project does not rule out or affect investment in another project.

Even then, a challenge would arise when the projects are mutually exclusive. If two or more projects are mutually exclusive, the decision to invest in one project precludes investment in all the others. With such projects, the IRR method may provide misleading results if used in isolation.

Shortcomings of IRR

There are some problems associated with the IRR method:

• the method assumes that all proceeds from a project are immediately reinvested in projects offering a rate of return equal to the IRR – this is very difficult in practice;
• it gives different rankings when the projects under comparison have different scales; and
• sometimes, the method may not provide a unique solution, especially when a project has a mixture of positive and negative cash flows during its productive life.
