Capital Investment Appraisal: Payback and NPV
Using relevant cash flows, payback and discounted net present value to compare projects and evaluate financial and non-financial consequences.
How to study A-level Accounting
Build each solution in a fixed order: identify the accounting relationship, record or calculate methodically, reconcile the result, then interpret it for the relevant decision and stakeholder.
Core concepts
Concept 1
Investment appraisal uses incremental project cash flows rather than accounting profit.
Exam cue: Build the cash-flow timeline and exclude sunk or non-cash accounting charges.
Concept 2
Payback focuses on recovery time, while net present value discounts cash flows and measures value at the required return.
Exam cue: Apply the discount factor to the cash flow in its correct period.
Concept 3
A recommendation should combine appraisal results with risk, assumptions, strategic fit, stakeholder and environmental effects.
Exam cue: Explain why payback and NPV can rank projects differently.
Risk pitfalls and guardrails
Using depreciation as a project cash outflow.
Guardrail: Do not select a familiar formula or entry until you have classified the accounts, period, user and decision named in the task.
Adding undiscounted future cash flows in an NPV calculation.
Guardrail: Do not select a familiar formula or entry until you have classified the accounts, period, user and decision named in the task.
Accepting a positive NPV without testing the assumptions or constraints.
Guardrail: Do not select a familiar formula or entry until you have classified the accounts, period, user and decision named in the task.
Memory anchors
Incremental Cash Flow
An incremental cash flow occurs because the project is undertaken.
Payback
Payback measures how long it takes to recover the initial cash outlay.
Discounting
Discounting converts a future cash flow to its present value.
Net Present Value
NPV is the present value of project inflows less the present value of project outflows.
Positive NPV
A positive NPV indicates value above the required return under the stated assumptions.
Appraisal Limitation
Appraisal results depend on forecast cash flows, timing, discount rate and non-financial constraints.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
