FNCE10002 Chap.6 Capital Budgeting and WACC
Capital Budgeting and WACC
Define net present value
The course material gives this chapter a concrete anchor: Weeks 7 and 9 cover project evaluation, incremental cash flows, decision methods and WACC.
That net present value anchor controls how incremental cash flow is explained and how weighted average cost of capital is tested in changed practice.
Capital Budgeting and WACC is a quantitative decision problem built from net present value, incremental cash flow and weighted average cost of capital.
The aim is to build incremental cash flows, discount them and interpret NPV with a matched WACC; a numerical result earns meaning only when the variables, units, assumptions and comparison are all explicit.
Begin with net present value: state what quantity it represents, the scale on which it is measured and the condition under which it changes.
Then map every symbol in the Capital Budgeting and WACC formula checkpoint to net present value before calculation begins.
Next connect incremental cash flow to the calculation. Show the incremental cash flow transformation line by line, preserve units and signs, and make any denominator or baseline visible.
A incremental cash flow calculator output is not a method; the reader must be able to reconstruct why that operation answers the question.
Formula checkpoint: net present value
NPV compares the initial outlay with discounted incremental cash flows at a risk-matched rate.
Trace incremental cash flow
Use weighted average cost of capital to interpret or stress-test the result.
Ask whether the weighted average cost of capital magnitude is plausible, whether a boundary case behaves as expected and which conclusion would reverse if an assumption changed. This is where computation becomes analysis rather than arithmetic.
When the task is to build incremental cash flows, discount them and interpret NPV with a matched WACC, separate inputs supplied by the problem from quantities you derive.
Then report the weighted average cost of capital result in the language of the course and attach the relevant uncertainty, limitation or decision consequence.
Build a representation check before solving.
Put net present value, incremental cash flow and weighted average cost of capital into a small symbol-and-units table, mark which values are observed and which are calculated, and predict the direction of the result before doing arithmetic.
A sign, scale or unit mismatch in net present value then becomes visible at setup instead of being hidden inside a polished final number.
Run one sensitivity test after the baseline answer. Change the input most closely connected to incremental cash flow, hold the remaining assumptions fixed and recompute only the affected steps. Explain whether the movement in weighted average cost of capital matches the mechanism.
This incremental cash flow sensitivity shows which assumption controls the conclusion and prevents a single scenario from being presented as universal.
Test with weighted average cost of capital
Use a three-column net present value error log for fnce10002: translation error, calculation error and interpretation error.
Record the exact line where the incremental cash flow solution first diverged, rewrite that line, and check it with a limiting case or an independent calculation.
Correcting the first failed incremental cash flow move is more useful than copying the complete solution again.
A complete response should make the task visible before the detail: identify what must be decided, define the relevant terms, connect the evidence to incremental cash flow, and use weighted average cost of capital to test the result.
The final sentence about weighted average cost of capital should answer the question actually asked rather than merely repeat the topic.
The controlling limit is specific: Financing weights or a corporate wacc may be inappropriate for a project with different risk.
Keep that weighted average cost of capital limit beside the worked example, because it separates a careful fnce10002 answer from one that sounds confident but claims more than the task or evidence supports.
For revision, retrieve net present value, incremental cash flow and weighted average cost of capital without notes, explain their relationship aloud, then complete a changed version of the application: build incremental cash flows, discount them and interpret NPV with a matched WACC.
Record the first failed incremental cash flow reasoning move and repair it before attempting another case.

Limits of incremental cash flow and weighted average cost of capital
Accept or reject a project
- 1Discount each of the three $8,000 cash flows.
- 1Sum present values and subtract $20,000.
- 1Calculate NPV of about $252.23.
- 1Accept only within the stated risk and cash-flow assumptions.
Key terms
- net present value
- Present value of incremental project cash flows less the initial investment. This chapter uses the concept when students build incremental cash flows, discount them and interpret NPV with a matched WACC. Use this definition when the task is to build incremental cash flows, discount them and interpret NPV with a matched WACC.
- incremental cash flow
- Cash flow that changes because the project is undertaken. It helps explain the reasoning required to build incremental cash flows, discount them and interpret NPV with a matched WACC. Use this definition when the task is to build incremental cash flows, discount them and interpret NPV with a matched WACC.
- weighted average cost of capital
- Market-value weighted required return on debt and equity financing under stated tax and risk conditions. Its limit matters because financing weights or a corporate WACC may be inappropriate for a project with different risk. Use this definition when the task is to build incremental cash flows, discount them and interpret NPV with a matched WACC.
Capital Budgeting and WACC FAQ
What is the main task in Capital Budgeting and WACC?
Build incremental cash flows, discount them and interpret npv with a matched wacc.
How do net present value and incremental cash flow work together?
Use net present value to establish the object or condition, then use incremental cash flow to explain how it changes the outcome being analysed.
What must a fnce10002 answer qualify here?
Financing weights or a corporate wacc may be inappropriate for a project with different risk.
How should I revise Capital Budgeting and WACC?
Retrieve net present value, incremental cash flow and weighted average cost of capital, apply them to a changed case, and correct the first point where the evidence no longer supports the conclusion.
Exam move
Reconstruct the relationship among net present value, incremental cash flow and weighted average cost of capital; complete the chapter application without notes; then test the result against this limit: Financing weights or a corporate wacc may be inappropriate for a project with different risk.
