Investment appraisal

What this book actually teaches

Investment appraisal — the process of evaluating whether a capital investment is worth making — sits at the intersection of accounting, finance, and corporate strategy. Uwe Götze's textbook on the subject takes a systematic approach to the methods practitioners and academics use to answer that question, with particular emphasis on quantitative techniques grounded in discounted cash flow theory.

The core argument is that no single appraisal method is sufficient on its own. Götze walks through the standard toolkit — net present value (NPV), internal rate of return (IRR), payback period, and profitability index — and explains not just how each works mechanically but where each one breaks down. NPV is theoretically superior, but it requires assumptions about discount rates that are themselves uncertain. IRR is intuitive but can produce multiple solutions for non-conventional cash flows. Payback period ignores the time value of money entirely but persists in practice because managers understand it. The book treats these tensions honestly rather than pretending that one method dominates.

A substantial portion of the text addresses the practical complications that textbook examples typically sidestep: inflation adjustments, tax effects, working capital changes, and risk and uncertainty modeling. Sensitivity analysis and scenario planning receive dedicated treatment, reflecting the reality that capital budgeting decisions depend on assumptions that may not hold. This is where the book adds genuine value over introductory corporate finance texts — it bridges the gap between clean theory and the messiness of real investment decisions.

The book is suited to finance students, MBA candidates, and corporate finance professionals who need a rigorous reference for evaluating capital projects. It is a textbook, not a practitioner guide — readers looking for applied deal-making intuition will find the academic framing demanding.

The main weakness is accessibility. The writing is dense and the mathematical notation assumes comfort with quantitative methods. Non-technical readers will struggle. The book also focuses almost entirely on the financial dimension of investment decisions and gives limited attention to strategic or qualitative factors — the question of whether an investment fits a firm's competitive position is largely outside its scope. Practitioners often find that the hardest part of capital budgeting is not computing the NPV but agreeing on the assumptions that go into it; the book could do more to address that challenge.

For a finance student or analyst who needs to understand the full range of investment appraisal techniques and their limitations, this is a thorough and honest reference. It is not a light read, but it covers the territory seriously.
