Project Evaluation for CS Professional Paper 5

Project evaluation is the process of deciding whether a long-term investment is worth making. You estimate incremental after-tax cash flows, then test them with techniques such as payback, ARR, NPV, PI and IRR, adjust for risk, and decide. Answer in the written format: method, calculation, conclusion.

What this chapter covers

Project Evaluation is the capital budgeting chapter of Paper 5, Strategic Management and Corporate Finance. It teaches you how a company decides whether to spend large sums on a plant, a new product or an expansion. The chapter moves in a clear line: estimate the cash flows, apply a technique, compare the results, allow for risk, and think about how the project will be financed.

The chapter sits in the Corporate Finance part of the paper, which carries 60 of the 100 marks. It links closely to cost of capital, because the discount rate used in NPV comes from there. It also links to capital structure and dividend decisions, since financing choices affect the rate at which you discount. Strategic management ties in too: a project must fit the firm's long-term direction, not just pass a numerical test.

The paper is written and case-based. You will be given figures about a project and asked to compute, compare and recommend. So the chapter rewards two skills: accurate step-by-step calculation, and a clear conclusion with a reason that a board could act on.

This chapter is numerical, and numerical answers can be scored carefully when you show every step. Project evaluation questions follow a few repeatable patterns, so practice pays off quickly. The same tools, especially present value and the discount rate, return in cost of capital, valuation and restructuring, so the effort here helps you in other papers too. Because answers are written, you also gain marks for stating the decision rule and giving a reasoned recommendation, not only for the final number.

Project Evaluation: topics in the order to study them

  1. 1Project Appraisal and Capital Budgeting BasicsIt defines the vocabulary, the stages of appraisal and the idea of the time value of money that every later topic uses.
  2. 2Estimating Project Cash FlowsEvery technique runs on cash flows, so you must learn what to include, such as tax, depreciation effects, working capital and salvage, and what to ignore, such as sunk costs.
  3. 3Non-Discounted Techniques: Payback and ARRThese are the simplest methods and show why ignoring the time value of money is a weakness.
  4. 4Discounted Techniques: NPV, PI and IRRThis is the core of the chapter and the most frequently tested calculation area.
  5. 5NPV vs IRR Conflicts and Capital RationingYou can only compare the methods and handle limited funds once you can compute each one correctly.
  6. 6Risk Analysis in Capital BudgetingRisk adjustments such as sensitivity analysis, scenario analysis and certainty equivalents build on the base-case NPV.
  7. 7Project Financing and Social Cost Benefit AnalysisIt widens the view to funding structures and public-interest appraisal, and is best read last as a more descriptive topic.

How to prepare Project Evaluation

Treat this chapter as a calculation chapter with a written conclusion. Build accuracy first, then speed, then the ability to explain.

  1. Read the basics and write a one-page list of terms: incremental cash flow, sunk cost, opportunity cost, discount rate and cut-off rate.
  2. Practise cash flow estimation on its own. Build a table of year-wise inflows after tax. Use either PAT + depreciation, or (cash flow before depreciation and tax) × (1 − t) + depreciation × t, where t is the tax rate. Apply one method consistently.
  3. Learn each technique's formula and decision rule, then solve at least three problems for each: payback, ARR, NPV, PI and IRR.
  4. For IRR, practise interpolation between two discount rates until you can do it without errors.
  5. Solve questions that ask you to rank projects by NPV, PI and IRR, and write a short note explaining why the rankings differ.
  6. Do the risk analysis and financing topics as short written answers. Prepare a few points each on sensitivity, scenario analysis, certainty equivalent and social cost benefit analysis.
  7. Finish with full past-style case questions under a time limit. Always end with a clear accept or reject recommendation.

Common mistakes in Project Evaluation

  • Including sunk costs or interest in project cash flows

    Fix: Before building the table, list each item and ask if it is incremental. Leave out past costs and handle financing cost through the discount rate.

  • Forgetting the tax effect of depreciation

    Fix: Compute profit after depreciation and tax, then add back depreciation. Or compute cash flow before depreciation and tax, deduct tax on it by multiplying by (1 − t), then add depreciation × t. Follow one method consistently.

  • Leaving out working capital recovery and salvage value

    Fix: Add a final-year checklist: working capital released, salvage value and any tax on sale.

  • Using the wrong discount factor or year

    Fix: Label the timeline from year 0. Use an annuity factor only when the flows are equal, and check each factor against the table given.

  • Giving a number without a decision

    Fix: State the rule, compare with the benchmark and write one sentence of recommendation.

  • Treating payback or ARR as sufficient for a recommendation

    Fix: Mention their limits and, where data allows, support the decision with a discounted technique.

Last-day revision: Project Evaluation

  • NPV = present value of cash inflows − present value of cash outflows; accept if NPV is greater than zero.
  • PI = present value of inflows ÷ present value of outflows; accept if PI is greater than 1.
  • IRR is the discount rate at which NPV is zero; accept if IRR is greater than the cost of capital.
  • Payback is the time taken to recover the initial investment; it ignores cash flows after that point and the time value of money in its simple form.
  • ARR = average accounting profit ÷ investment (initial or average, as the question states); it uses profit, not cash flow.
  • Use incremental, after-tax cash flows only; ignore sunk costs and include opportunity costs.
  • Depreciation is a non-cash charge. Either add it back in full to profit after tax (which already captures its tax saving), or compute cash flow before depreciation and tax, deduct tax on it by multiplying by (1 − t), then add depreciation × t. Do not do both.
  • Recover working capital and salvage value in the final year.
  • For mutually exclusive projects with conflicting ranks, NPV is generally preferred.
  • Under capital rationing, select the combination of projects with the highest total NPV within the budget.
  • Sensitivity analysis changes one variable at a time; scenario analysis changes several together.
  • Social cost benefit analysis weighs benefits and costs to society, not only to the firm.

Project Evaluation: frequently asked questions

Is Project Evaluation mostly numerical or theory?

It is mostly numerical, with a smaller theory part. Risk analysis, project financing and social cost benefit analysis are often asked as short written answers. Prepare both sides.

Which technique should I prioritise?

Give most time to NPV and IRR, including PI and the conflict between them. They carry the heaviest calculation load and the most discussion.

Do I need present value tables in the exam?

Questions usually supply the discount factors needed. Still, practise reading them correctly and know the formula behind them so you can check a value.

How do I handle NPV and IRR giving different rankings?

Explain the reason, such as different project size, timing of cash flows or reinvestment assumption. Then state that NPV is generally preferred for mutually exclusive projects and give your recommendation.

How long should I spend on this chapter?

Spend enough time to solve each type of problem several times. Accuracy under written exam conditions matters more than reading the theory repeatedly.
