This paper discusses internal rate of return (IRR) and other capital appraisal techniques used to evaluate investment projects. The IRR is calculated for a specific project and compared to other techniques such as payback period, net present value (NPV), and accounting rate of return (ARR). The usefulness of these techniques is analyzed, highlighting the strengths and limitations of each method. The paper concludes that while IRR is simple and easy to calculate, NPV is more suitable for long-term projects and for comparing multiple projects.
