Capital Budgeting and Project Appraisal for CA Final

Updated 5 October 2026 · Fact-checked

Capital budgeting is choosing long-term projects by comparing the present value of their future cash flows with the outlay. Forecast incremental after-tax cash flows, pick a discount rate that reflects risk, compute NPV and IRR, adjust for risk or rationing, and accept projects that add value.

Understand Capital Budgeting and Project Appraisal

Capital budgeting asks one question: will this project add to shareholder wealth? You answer it by forecasting the extra cash the project creates, discounting it at a rate that matches its risk, and comparing it with the money you put in.

NPV is the main tool. It is the present value of inflows minus the present value of outflows. A positive NPV means the project earns more than the required return. IRR is the discount rate at which NPV is zero. It is useful, but it can mislead when projects are mutually exclusive, have different sizes or lives, or have non-conventional cash flows.

Risk is handled in two ways. The risk-adjusted discount rate (RADR) raises the rate for riskier projects. The certainty equivalent (CE) method scales each cash flow down to a sure amount using a coefficient between 0 and 1, then discounts at the risk-free rate. Sensitivity, scenario, simulation and decision-tree analysis show how the result changes when inputs change.

Real options value flexibility that plain NPV ignores: to expand, delay, abandon or switch. A project with a slightly negative static NPV may be worth doing if the option value is large enough. In an exam, treat option value as an addition to the base NPV.

Capital rationing applies when the budget is limited. Then you cannot accept every positive-NPV project. You choose the combination that gives the highest total NPV within the budget. For divisible projects, rank by profitability index. For indivisible projects, test feasible combinations.

Key rules to remember

Net Present Value: NPV = Σ [CFt ÷ (1 + k)^t] − Initial outlay; Use incremental after-tax cash flows. Include working capital and its recovery, and salvage value. Accept if NPV > 0.
Internal Rate of Return: IRR: Σ [CFt ÷ (1 + IRR)^t] = Initial outlay; Find by interpolation between two rates where NPV changes sign. Accept if IRR > cost of capital, but use NPV for mutually exclusive choices.
Profitability Index: PI = PV of inflows ÷ Initial outlay = 1 + NPV ÷ Outlay; Accept if PI > 1. Under capital rationing with divisible projects, rank on NPV ÷ Outlay (PI − 1).
Certainty equivalent coefficient: α = Certain cash flow ÷ Risky expected cash flow; α lies between 0 and 1. A lower α means higher risk or less tolerance for risk in that year.
Certainty equivalent NPV: NPV = Σ [αt × CFt ÷ (1 + Rf)^t] − Outlay; Discount at the risk-free rate only. Do not use the risk-adjusted rate here, or you count risk twice.
Risk-adjusted discount rate: RADR = Risk-free rate + Risk premium for the project; Use RADR on the unadjusted expected cash flows.
Standard deviation of project NPV (independent yearly flows): σNPV = √ Σ [σt² ÷ (1 + Rf)^(2t)]; Valid only if cash flows of different years are independent. If perfectly correlated, add the discounted SDs instead.
Expanded NPV with real options: Expanded NPV = Static NPV + Value of option(s); Option value is usually given or found from a decision tree or Black-Scholes in the question.
Equivalent Annual Cost/Benefit: EAC = NPV (or PV of costs) ÷ Annuity factor for project life; Use to compare mutually exclusive projects with unequal lives.

How to solve Capital Budgeting and Project Appraisal questions

Use the same sequence for any capital budgeting question, whether it is a numerical or a case in Paper 6.

1Read the case and list the decision: accept or reject, choose one of several, or choose a set under a budget.
2Build the incremental after-tax cash flows year by year. Add depreciation tax shield, working capital changes and salvage. Ignore sunk costs, allocated overheads and financing charges.
3Choose the discount rate: the cost of capital, a RADR, or the risk-free rate if you are using certainty equivalents.
4Compute NPV, and IRR or PI if asked. Show the discount factors and the total clearly.
5Apply the risk treatment asked for: CE coefficients, RADR, sensitivity, scenario, expected value or SD.
6If there is a budget limit, rank by PI for divisible projects. For indivisible projects, list feasible combinations and compare total NPV.
7Add real option value where the case mentions expansion, delay or abandonment.
8State the decision with the reason in one or two lines, and note the key assumption or risk.

Quickest way: NPV-first shortcut

When to use it: Use when time is short and the question gives clean cash flows or a choice between projects.

Decide the rate first and write the discount factors in a small column before touching cash flows.
Compute NPV only. Calculate IRR only if the question asks for it, and then interpolate between two close trial rates.
For rationing, compute NPV ÷ outlay for each project straight away and rank. Then check the indivisible case by trying the best two or three combinations.
For CE, multiply each cash flow by its α first, then discount once at the risk-free rate.
Finish with a one-line decision. Marks are often given for the conclusion.

Common mistakes in Capital Budgeting and Project Appraisal

Discounting certainty equivalent cash flows at the risk-adjusted rate.
Students remember that a higher rate means risk and apply it by habit.
Fix: CE already removes risk from the cash flows. Discount at the risk-free rate only.
Trusting IRR to choose between mutually exclusive projects.
IRR is easy to compare as a percentage, so it looks decisive.
Fix: Rank by NPV. IRR can conflict with NPV because of scale, timing or unequal lives. Mention the reinvestment assumption in the answer.
Including sunk costs, interest on funds or allocated overheads in cash flows.
The question lists many costs and students treat them all as relevant.
Fix: Include only incremental cash flows. Financing cost is already in the discount rate.
Choosing projects by NPV rank alone under capital rationing.
Students forget the budget is the scarce resource.
Fix: Rank by NPV per rupee of outlay for divisible projects. For indivisible ones, compare total NPV across feasible combinations.
Forgetting working capital recovery and salvage value in the final year, or tax on salvage.
These items sit in the notes of the question, not the main table.
Fix: Tick a checklist: outlay, working capital in and out, depreciation tax shield, salvage and its tax effect.
Ignoring real options and giving only a static NPV for a flexible project.
Students treat the option as theory, not as part of the answer.
Fix: When the case mentions expand, defer or abandon, compute the expanded NPV and say the decision may change.

Worked examples

Example 1

Case: Varun Textiles is evaluating a new dyeing unit costing ₹10,00,000 now. Expected cash inflows are ₹4,00,000, ₹5,00,000 and ₹6,00,000 at the end of years 1, 2 and 3. The management's certainty equivalent coefficients are 0.90, 0.80 and 0.70 for the three years. The risk-free rate is 6%. Should the unit be accepted using the certainty equivalent method?

Show the solution

Convert to certain cash flows: Year 1 = 4,00,000 × 0.90 = ₹3,60,000. Year 2 = 5,00,000 × 0.80 = ₹4,00,000. Year 3 = 6,00,000 × 0.70 = ₹4,20,000.
Discount at the risk-free rate of 6%. Factors: Year 1 = 0.9434, Year 2 = 0.8900, Year 3 = 0.8396.
PV: Year 1 = 3,60,000 × 0.9434 = ₹3,39,624. Year 2 = 4,00,000 × 0.8900 = ₹3,56,000. Year 3 = 4,20,000 × 0.8396 = ₹3,52,632.
Total PV = 3,39,624 + 3,56,000 + 3,52,632 = ₹10,48,256.
CE NPV = 10,48,256 − 10,00,000 = ₹48,256.

Answer: CE NPV is ₹48,256, which is positive, so accept the unit. The margin is thin, so a small fall in the coefficients could change the decision.

Example 2

Case: Kaveri Ltd has a capital budget of ₹10,00,000. Its proposals are: A (outlay ₹4,00,000, NPV ₹1,00,000), B (outlay ₹3,00,000, NPV ₹90,000), C (outlay ₹5,00,000, NPV ₹75,000) and D (outlay ₹2,00,000, NPV ₹20,000). Find the best selection (i) if projects are divisible and (ii) if they are indivisible.

Show the solution

Compute NPV ÷ outlay: A = 0.25, B = 0.30, C = 0.15, D = 0.10. Ranking: B, A, C, D.
(i) Divisible: take B fully (₹3,00,000) and A fully (₹4,00,000). Used ₹7,00,000. Balance ₹3,00,000 goes to C, which is 3/5 of C.
NPV from 3/5 of C = 75,000 × 3/5 = ₹45,000. Total NPV = 90,000 + 1,00,000 + 45,000 = ₹2,35,000.
(ii) Indivisible: test feasible combinations. A + B + D = ₹9,00,000 outlay, NPV = 1,00,000 + 90,000 + 20,000 = ₹2,10,000.
Others: A + C = ₹9,00,000, NPV ₹1,75,000. B + C + D = ₹10,00,000, NPV ₹1,85,000. B + C = ₹8,00,000, NPV ₹1,65,000. A + B = ₹7,00,000, NPV ₹1,90,000.
The highest is A + B + D at ₹2,10,000. Combinations including A, B and C exceed the budget.

Answer: If divisible: B, A and 3/5 of C, total NPV ₹2,35,000. If indivisible: A, B and D, total NPV ₹2,10,000, using ₹9,00,000 of the budget.

Exam tips

In Paper 6 cases, state the decision and the reason in the first line of the answer, then show the working.
Show discount factors and the rate used. Marks are given for method even if one figure is off.
For MCQs on NPV vs IRR, think about scale, timing and non-conventional cash flows. These are the usual traps.
When the case hints at flexibility such as phased expansion or exit, mention real options even if no figure is asked.
Under capital rationing, always say whether projects are divisible, and state your assumption if the question does not.

Capital Budgeting and Project Appraisal: frequently asked questions

How do I calculate certainty equivalent NPV?

Multiply each expected cash flow by its certainty equivalent coefficient. Discount these certain amounts at the risk-free rate. Subtract the initial outlay to get the CE NPV.

What is the difference between NPV and IRR under capital rationing?

NPV gives the absolute value added, while IRR gives a percentage return that ignores project size. Under rationing, neither alone is enough. Use NPV per rupee of outlay (PI) for divisible projects, and compare total NPV of feasible combinations for indivisible ones.

When should I use RADR and when certainty equivalent?

Use RADR when the question gives a risk premium or a project-specific rate. Use CE when it gives coefficients. Never combine the two on the same cash flows.

How is capital budgeting tested in the IBS case study paper?

You get a business case with financial data and must advise on accepting a project. Expect NPV, risk treatment and a link to financing or strategy. Your conclusion with reasons is as important as the calculation.

Do real options always change the decision?

No. They add value to the static NPV, but the decision changes only if the added value turns a negative NPV positive or alters the ranking. Always compute the expanded NPV before concluding.
