ACCA FM NPV: Why You're Losing Marks on the Profit-to-Cash-Flow Adjustment
More than half of FM candidates fail every sitting. One of the biggest reasons: they give the examiner profit figures when NPV needs cash flows. The March/June 2025 examiner's report called it out explicitly — too many candidates didn't adjust at all, and many who tried only made one of the two required adjustments.
Here's what you need to know before your next sitting.
What the Examiner Actually Said
In the March/June 2025 exam, candidates were given forecast (loss)/profit figures for a project and asked to calculate NPV. The case involved a company called Sulu Co, and the Year 1 figure showed a forecast loss of $75,000.
The examiner's verdict was damning: "Unfortunately, too many candidates did not make either of these adjustments from (loss)/profit to cash flow, made only one of the adjustments or made errors in the adjustment(s) such as deducting the costs rather than adding them back."
This isn't a one-off. The FM pass rate hovers around 44–48% consistently. Exam technique — not syllabus knowledge — is what separates candidates who pass from those who don't.
Why the Adjustment Matters
NPV is a discounted cash flow (DCF) technique. It doesn't care about accounting profit — it cares about cash in and cash out. When an exam question hands you a profit figure, it has almost certainly already deducted items that are not cash flows. Your job is to reverse those deductions before you discount.
There are two main culprits the examiner keeps flagging:
1. Depreciation — not a cash flow. Add it back. In the Sulu Co question, machinery costing $600,000 was depreciated straight-line over four years: $600,000 ÷ 4 = $150,000 per year. That $150,000 had been deducted to arrive at the profit figure. It needed to be added back.
2. Amortisation of sunk costs — sunk costs are not relevant to the NPV decision and their amortisation is not a cash flow. In Sulu Co, R&D costs of $200,000 were already spent (sunk), and $50,000 per year was being amortised. That $50,000 also needed adding back.
Worked Example: Sulu Co Year 1
This is what most candidates submitted — and it cost them marks:
Wrong approach:
Year 1 cash flow = ($75,000) — just used the profit figure directly, or worse, also subtracted the non-cash items a second time.
Correct approach:
Start with the forecast loss: ($75,000)
Add back amortisation of R&D sunk cost: +$50,000
Add back depreciation on machinery: +$150,000
Operating cash flow Year 1 = $125,000
That's a swing of $200,000 in a single year. Across four years of the project, that kind of error compounds — and it flows into the tax calculation too, because the examiner also flagged that candidates got the direction of tax cash flows wrong when their adjusted operating figure was incorrect.
The Tax Trap That Follows
Once you have your operating cash flows wrong, your tax goes wrong too. The Sulu Co report noted that candidates were "incorrectly adding a tax payment" when the cash flow was negative — a sign that many weren't thinking about what a negative operating cash flow actually means for tax relief.
For a profitable company, a negative operating cash flow generates a tax relief — an inflow. Several candidates either showed it as an outflow or omitted it entirely. The examiner was clear: always work out what the tax liability looks like, check the direction, and show your workings.
Three Things to Do Before Your Exam
1. Build a habit of asking: "Is this profit or cash?" Every time a Section C question gives you an income statement or mentions profit, write those words at the top of your working. Force yourself to make the adjustment consciously rather than rushing past it.
2. Memorise the common non-cash items to reverse: depreciation, amortisation, and any sunk cost allocation. These appear in almost every investment appraisal question. Sunk costs themselves are excluded entirely — only the non-cash amortisation is added back; there is no future cash flow for a cost already spent.
3. Practice on the ACCA Practice Platform using the spreadsheet. The MJ 2025 examiner specifically recommended using the NPV formula in the spreadsheet — with the T0 outlay kept separate from the T1–T4 cash flows, since the NPV function assumes the first cash flow is at T1. Use it exactly as the examiner describes in the published sample exam.
The Bottom Line
FM has a consistent pass rate of around 44–47%. The candidates who pass aren't necessarily smarter — they're more deliberate. They check whether figures are profit or cash, they add back non-cash items before discounting, and they show their workings so method marks can be awarded even when a number is wrong.
The examiner has now flagged this profit-to-cash-flow adjustment in multiple reports. It will come up again. Make sure you're not leaving those marks behind.
