Research on investment project evaluation: Comparative analysis based on NPV and IRR

Abstract

Whether a project is viable, determining whether a project is viable requires some metrics. The indicators that are most frequently utilized are the Net Present Value (NPV) and the internal rate of return (IRR). They are very representative and scientific. The same decision can be made by applying both in independent and non-independent projects When there are many contradictions between NPV and IRR, it is necessary to introduce new indicators to continue to judge the project, such as △IRR, incremental IRR method, modified IRR (MIRR) method, selective IRR method, payback period method, Equivalent Annual Annuity (EAA) method and static analysis method. The investment is selected by comparing the internal rate of return △IRR with the benchmark rate of return (ic) or the social discount rate. The MIRR approach determines the IRR of each scheme, compares it to ic, chooses the scheme that have IRR is larger than or the same as ic, and then determines the incremental IRR of the two neighboring schemes to make the choice. In addition to the investment payback period approach and the selective internal rate of return method. EAA method is in the comparison of investment projects, investors should choose the project with higher EAA when comparing. In the process of investment projects, different enterprises can adopt static analysis method to carry out project investment, but there are two forms of static analysis method, such as payback period method and basic income method. Using reasonable indicators and methods to evaluate the investment project, so as to select the best project.
