What conditions can cause the IRR and NPV methods to produce conflicting rating?

The underlying cause of the NPV and IRR conflict is the nature of cash flows (normal vs non-normal), nature of project (independent vs mutually-exclusive) and size of the project. Independent projects are projects in which decision about acceptance of one project does not affect decision regarding others.

What is the underlying cause of ranking conflicts between NPV and IRR methods is differing?

Q10: The underlying cause of ranking conflicts between the net present value (NPV) and internal rate of return (IRR) methods is the underlying assumption related to the: The IRR method assumes all future cash flows can be reinvested at the IRR. This may not be feasible because the IRR is not based on market rates.

Under what circumstances do the NPV and IRR method differ?

The NPV method results in a dollar value that a project will produce, while IRR generates the percentage return that the project is expected to create. Purpose. The NPV method focuses on project surpluses, while IRR is focused on the breakeven cash flow level of a project.

What two conditions can lead to conflicts between the NPV and the IRR when evaluating mutually exclusive projects?

For single and independent projects with conventional cash flows, there is no conflict between NPV and IRR decision rules. However, for mutually exclusive projects the two criteria may give conflicting results. The reason for conflict is due to differences in cash flow patterns and differences in project scale.

Under what conditions will IRR and NPV be consistent when accepting or rejecting projects?

The decision rule for NPV is to accept the project if the NPV is positive and reject the project if the NPV is NPV is negative. The decision rule for IRR is to accept the project if the IRR equals or is greater than the required rate of return and reject the project if the IRR is less than the required rate of return.

Under what circumstances will the NPV and IRR methods give the same Accept Reject decision?

With NPV, proposals are usually accepted if they have a net positive value, while IRR is often accepted if the resulting IRR has a higher value compared to the existing cut off rate. Projects with a positive net present value also show a higher internal rate of return greater than the base value.

What are the conditions that lead IRR and NPV rules having identical decisions?

They are: i) If the projects are independent and the cash inflow of the projects are positive without even a single negative cash flow during the life of the project both NPV and IRR will give the same result. ii) The life of the project should be the same, and there should be no multiple investments in the project.

What is the conflict between NPV and IRR?

The root cause of the conflict between NPV and IRR is the rate of return at which differential cash flows can be reinvested. Both the NPV and IRR methods assume that the firm will reinvest all early cash flows.

What is the difference between net present value and IRR?

The net present value (NPV) and internal rate of return (IRR) methods are based on the same discounted cash flows technique, hence they take into account the time value of money concept. Furthermore, both of them are frequently used in capital budgeting decisions. In most cases, they provide the same appraisal, but conflict can sometimes occur.

What are the limitations of IRR in project management?

However, IRR’s assumption of reinvestment at IRR is unrealistic and could result in inaccurate ranking of projects. Another, quite serious weakness is the multiple IRR problem. In case of non-normal cash flows, i.e. where a project has positive cash flows followed by negative cash flows, IRR has multiple values.

Is NPV or IRR the best criteria when ranking investments?

Actually, NPV is considered the best criterion when ranking investments. Both NPV and IRR are sound analytical tools. However, they don’t always agree and tell us what we want to know, especially when there are two competing projects with equally favorable alternatives.
