A business can be genuinely profitable and still run out of — a , stock sitting unsold, or one large capital purchase can each turn a profitable month into a cash crisis. Pearson tests profit and cash as two separate skills, not two names for the same idea, and the same distinction resurfaces as in 2.3.3.
Key terms in this lesson
Before you read on
Two or three questions on exactly what this lesson teaches. Being wrong here is fine — it's the fastest way to find out what to pay attention to next.
Profit is a record; cash flow is a forecast of money actually moving
and answer different questions. Profit compares total revenue against total cost for a period, and — as the accounting convention behind 2.3.3.1 requires — revenue is recorded when a sale happens, not when the cash for it arrives. Cash flow tracks something narrower and more literal: money physically entering or leaving the business bank account, in the month it actually does so. A sale made on 30-day is revenue the month it's made and a cash inflow the month it's paid — usually a different month entirely. Unsold stock sitting on a shelf has already cost cash to buy, but contributes nothing to profit until it's sold. And a large capital purchase — new equipment, a shop refit — is paid for in cash in full, upfront, in the month of purchase, while accounting spreads that same cost out instead of charging it all at once: depreciation is the accounting charge that writes off a small, fixed slice of an asset's original cost against profit each period — on the simplest (straight-line) method, cost ÷ useful life in years — rather than treating the whole purchase as a one-off hit to profit in the month it's bought. All three are the same underlying mechanism: profit and cash can diverge sharply in any single month, even for a business that is comfortably profitable overall — which is exactly why 2.3.3.2's content treats 'distinction between profit and cash' as its own named spec point, not a footnote to this one.
A makes this divergence visible before it happens. Its structure is simple and mechanical: for each period, opening balance (last period's closing balance, carried forward) plus (total cash inflows minus total cash outflows for that period alone) equals closing balance — which then becomes next period's opening balance. Build it forward, month by month, and a business can see exactly which future month its balance is projected to run short, while there's still time to act.
A is a financial plan, agreed and prepared in advance, setting a target figure for revenue, a cost, or profit over a coming period. Pearson names two ways of arriving at that figure. Historical-figures (incremental) budgeting takes last period's actual or budgeted figure and adjusts it — up for expected growth or inflation, down for a planned cut — which is fast to prepare but silently carries forward any waste or unjustified spending that was already baked into last period's number. starts every single line at £0 each period and requires it to be justified fresh from first principles, which catches spending that no longer needs to happen, at the cost of being far more time-consuming to prepare — a genuine in its own right, not a free upgrade.
Once a budget exists, comparing it against what actually happened is — a comparison only possible once a period has ended and the actual figures are finally known, not while it's still in progress: for any line, variance = actual − budgeted. The mechanism block below derives why the same £-sized variance can be good news on one line and bad news on the next, rather than asking you to memorise a table of which lines are 'supposed' to go up and which are 'supposed' to go down.
Mechanism
Why the same variance is favourable on one line and adverse on the next
A budget is a target built out of a firm's forecast revenue and forecast costs — and profit is nothing more than revenue minus costs. So the real question a variance answers isn't 'did this number go up or down', it's 'did this change move actual profit above or below the budgeted profit'. That single question, applied consistently, is the whole mechanism: on a revenue line, actual coming in above budget means more money earned than planned, which pushes profit up relative to budget — favourable. On a cost line, actual coming in above budget means more money spent than planned, which pushes profit down relative to budget — adverse. It's the identical underlying test (does this raise or lower profit against budget) landing on opposite verdicts purely because revenue and cost enter the profit equation with opposite signs — profit = revenue − cost. There is one rule (impact on profit) that points in opposite directions depending on which side of the minus sign the line sits on. This is exactly why Pearson's own Explain-question mark scheme rewards a stated direction, not just a number: 'the ingredient cost was £200 higher than budgeted' is an observation, but 'which is adverse, because it reduces profit below the budgeted figure' is the actual analytical move the AO3 mark is checking for.
Worked, in full
Harlow Bakes' four-month cash-flow forecast — and why it stays profitable throughout
- 01
Harlow Bakes (VERIDIAN-original example) sells bread over the counter for cash, and wholesale to local cafés on 30-day credit terms. Its January opening cash balance is £1,000. Structure for every month: opening balance + net cash flow = closing balance, and net cash flow = total inflows − total outflows.
Earns: K — the forecast's own formula stated explicitly before any figures are plugged in, not skipped straight to a finished table.
- 02
January: cash inflow is £3,000 in over-the-counter sales plus £3,800 received from December's credit sales, invoiced 30 days earlier — total inflow £6,800. Cash outflow is £2,200 ingredients, £2,000 wages, £800 rent — total outflow £5,000. Net cash flow = £6,800 − £5,000 = £1,800. Closing balance = £1,000 + £1,800 = £2,800.
Earns: An1 — inflows and outflows built up from named components, not asserted as totals, and the credit-sale timing lag (December's sale, January's cash) applied concretely.
- 03
February: inflow £3,200 cash sales + £4,000 received from January's credit sales = £7,200. Outflow £2,400 ingredients + £2,000 wages + £800 rent = £5,200. Net = £2,000. Closing balance = £2,800 + £2,000 = £4,800 — the balance is growing steadily so far.
Earns: An1 (repeated) — the same structure applied to a second month, confirming the pattern rather than treating January as a one-off.
- 04
March: inflow £3,500 cash sales + £4,500 received from February's credit sales = £8,000. But Harlow Bakes also buys a new commercial oven this month for £10,000, paid in full, in cash, immediately. Outflow = £2,600 ingredients + £2,000 wages + £800 rent + £10,000 oven = £15,400. Net cash flow = £8,000 − £15,400 = −£7,400. Closing balance = £4,800 − £7,400 = −£2,600 — the account is overdrawn.
Earns: An2 — the capital-purchase mechanism from the teach block made concrete: the full £10,000 hits cash in one month, forcing a negative closing balance the forecast reveals in advance.
- 05
Yet Harlow Bakes' accounting profit is positive in every one of these four months, including March: the oven is only charged against profit as depreciation (the straight-line charge defined above: £10,000 cost ÷ 5-year useful life = £166.67 a month), not as a one-off £10,000 hit — so March's accounting profit is £2,933.33, its highest month yet, even while its cash balance is −£2,600. April's inflow (£3,800 + £5,000 from March's credit sales = £8,800) against outflow of £5,600 gives net cash flow +£3,200, recovering the balance to +£600. Seeing the March dip a month in advance, from the forecast alone, is what lets the business arrange a short-term overdraft before the shortfall happens rather than discovering it the day a payment bounces.
Earns: Eval — profit and cash shown numerically diverging in the same month, from the same business, closing the loop the teach block opened with an assertion.
x-axis: Month (1 = January … 4 = April) · y-axis: Closing cash balance, £
- Closing balance
- Rises steadily in January (£2,800) and February (£4,800), drops sharply below zero in March (−£2,600) when the oven is paid for in cash, then partially recovers in April (£600) as March's credit sales are finally received.
- March
- The only month the line crosses below the zero axis — driven entirely by the timing of one cash outflow (the oven), not by the business becoming unprofitable. Accounting profit is actually higher this same month than in either January or February — its best month yet on paper, even as the cash balance turns negative.
- Zero line
- Below this line the business needs external short-term finance (an overdraft) to cover its obligations — the forecast's whole practical value is showing this line will be crossed before it happens, not just recording that it did.
Common error: Assuming a negative closing balance in one month means the business is loss-making, or panicking and treating it as identical to a long-run liquidity crisis.
Correct: Reading the negative balance as a timing problem specific to named cash items (a lump-sum capital purchase, a lag on credit receipts) — check the accounting profit for the same month before concluding anything about the underlying health of the business. That verdict is specific to THIS pattern: one bad month, driven by a named one-off item, that fully recovers the next. A forecast where cash inflow keeps falling month after month, or where net cash flow turns negative and stays negative with no recovering month in sight, is a genuinely different signal — the kind of real problem an exam question credits as needing the business to find ways to raise revenue, or to arrange finance to cover an ongoing shortfall — not something the 'check accounting profit first' reasoning above should be used to wave away.
In your own words
In one sentence: why does Harlow Bakes record its highest accounting profit so far in the exact same month its cash balance turns negative?
Complete it yourself
Complete the chain — a rent variance
- 01
Harlow Bakes budgets rent for June at £800, the same figure it's paid every month so far. Actual rent paid in June is £850, because the landlord raised it partway through the lease.
- 02
The variance is actual − budgeted = £850 − £800 = £50.
Named traps
- total-not-per-unit
- Confirmed in the October 2022 examiner report (Q2b) on a closely related calculation: some candidates calculated variable cost per unit when the question asked for total variable costs per month — partial credit was possible only where the misread calculation happened to overlap with correct application steps, and full marks were not achievable. A cash-flow forecast and a budget both work in TOTAL £ for the period, not £ per unit — check which one a question actually asks for before calculating either.
- direction-must-be-stated-not-just-implied
- Confirmed in the January 2023 examiner report, Q1(b) — an Explain question on break-even, but on this same 4-mark tariff structure (1 knowledge + 2 application + 1 analysis) that break-even, contribution and budgets all share: "Stating that the break-even point would be affected did not answer the question, it was necessary to say it would increase." The same rule applies directly to a variance answer — a change described but not directed ("the variance would be affected", "profit would change") does not earn the analysis mark. Say which way, every time: favourable or adverse, higher or lower, by how much.
- missing-the-sign-caps-the-mark
- Confirmed, worded almost identically in every WBS12 series with a Calculate question reviewed: "Examiners awarded a maximum of 3 marks if the percentage sign was missing" (Jan 2020) — the same principle applies to a missing £ sign or a missing favourable/adverse label on a variance answer. A numerically correct figure without its unit or direction is marked as incomplete, not as merely untidy.
- extract-copied-not-applied
- Confirmed as one of the most consistently repeated findings across the whole archive: "Application marks will not be awarded for simply repeating evidence in the extracts. The evidence needs to be used in the response", and separately (verbatim in the October 2022 and January 2023 examiner reports specifically), "stating a part of the extract in isolation is NOT application." On a cash-flow or budget question with a source extract, quoting a figure from it earns nothing by itself — the figure has to be used inside a chain of reasoning (calculated with, compared against, or used to justify a conclusion), not simply restated.
- definition-cannot-be-applied-or-analysed
- Confirmed, near-verbatim across seven of the thirteen examiner reports reviewed: "it is not possible to apply or analyse the definition." On a 6-mark Analyse question involving budgets or cash flow, restating what a budget or a cash-flow forecast IS earns the knowledge mark at most — the application and analysis marks require using the specific numbers or context given, not a second, more detailed definition.
- generic-forecast-limitation-instead-of-specific-reading
- Confirmed verbatim in the January 2022 examiner report, on exactly this question type ("analyse two possible problems... from its cash flow forecast"): "Some students did not answer the question, instead attempting to analyse generic problems of using a cash flow forecast." The credited answers instead read specific patterns out of the actual forecast numbers given — a genuinely worsening trend in cash inflow across the months shown, or a net cash flow that turns negative and stays that way with no month recovering — each tied to what the business should do about it (raise revenue, or arrange finance to cover the shortfall). Restating "forecasts are only built on estimates, so they can turn out to be wrong" is a real, separately-credited limitation (see the MCQ above) — but on a question asking what problems THIS forecast's own numbers reveal, it answers a different question and earns nothing.
The conditional move
Complete: "A cash-flow forecast can be relied on to plan a business's financing decisions only if ___."
Complete: "Zero-based budgeting is worth its extra preparation time and cost only if ___."
Beyond the spec
The spec treats every budgeted figure as a single, fixed target to compare actual results against — but that risks calling a genuine overspend 'adverse' when it was actually caused by producing and selling more than planned, not by poor cost control. Knowing the real-world fix sharpens exactly what a variance is supposed to be measuring, and it's the kind of practical refinement a management-accounting course teaches that an A-level spec has no room for.
Real management accounting (as taught at the level just above this one, in professional qualifications like ACCA and CIMA) distinguishes a fixed budget from a flexible budget. A fixed budget, which is what this spec's variance analysis assumes, is set once at one assumed output level and never adjusted. A flexible budget is recalculated after the fact at the ACTUAL output level achieved, before comparing it to actual costs — so a factory that budgeted for 1,000 units but produced and sold 1,200 gets its material-cost budget scaled up to a 1,200-unit equivalent first, and only the remaining gap (spending more per unit than expected, not just spending more in total because more was made) counts as a genuine adverse variance. Without this adjustment, a manager who simply sold more than forecast — good news — can end up with an 'adverse' cost variance purely from volume, which sends exactly the wrong signal about their actual cost control. Businesses that separate a 'volume variance' (caused by producing a different quantity than planned) from other genuine efficiency and price variances get a much sharper picture of where money was actually managed well or badly — the spec's simpler actual-vs-budget comparison is a real technique, just the first rung of a taller ladder.

Harlow Bakes budgets its July ingredient costs at £2,750. Actual July ingredient costs are £2,950, because flour prices rose unexpectedly during the month.
Which of the following correctly calculates and explains the ingredient-cost variance for July, to the standard a 4-mark Calculate/Explain question on this paper actually credits?
In August, Harlow Bakes' opening cash balance is £600. Cash sales that month total £3,900. Credit sales invoiced in July, £4,600, are received in August. Cash outflows for August total £8,100, including a one-off £3,500 shop refurbishment.
Calculate Harlow Bakes' closing cash balance for August.
A different bakery's four-month cash-flow forecast shows total cash inflow falling every month (£9,000, then £7,600, £6,300, £5,200), while net cash flow falls from +£1,200 in month 1 to −£1,800 in month 4, with no month recovering.
Which of the following correctly identifies the genuine problem this forecast reveals?
Same question, every level
Discuss the extent to which switching from historical-figures budgeting to zero-based budgeting would benefit Harlow Bakes. (VERIDIAN-original question, written to this paper's own confirmed 8-mark Discuss tariff — Section A/B, levels-based, 3 levels, no conclusion required — not a reproduction of any past-paper question.)
8 marks available
Zero-based budgeting checks every cost from £0 each year instead of just adjusting last year's figures. This means Harlow Bakes would have a more accurate budget, so it should switch to zero-based budgeting.
A generic assertion with no named cost line, no mechanism for why starting from £0 produces a more accurate figure, and no application to Harlow Bakes' own situation beyond restating what zero-based budgeting is. Matches the confirmed 8-mark L1 (1-2) descriptor: 'Isolated elements of knowledge and understanding – recall based. Weak or no relevant application to business examples. Generic assertions may be presented.'
Same question, every level
Assess the extent to which a favourable variance on Harlow Bakes' monthly ingredient costs indicates genuinely good cost control. (VERIDIAN-original question, written to this paper's own confirmed 10-mark Assess tariff — levels-based, 4 levels, requiring a supported judgement — not a reproduction of any past-paper question.)
10 marks available
A favourable variance means the actual cost was lower than budgeted, which is good news. So a favourable ingredient-cost variance shows Harlow Bakes is controlling its costs well.
A generic assertion with no mechanism for WHY the cost came in lower, and no consideration of any other possible cause — isolated Level 1 language matching the verified descriptor: 'Isolated elements of knowledge and understanding – recall based. Weak or no relevant application to business examples. Generic assertions may be presented.'
Same question, every level
Evaluate the extent to which producing a detailed cash-flow forecast would reduce a small bakery's risk of business failure. (VERIDIAN-original question, written as a Section C-style 20-mark Evaluate essay on this spec point, deliberately drawing the forward link to 2.3.3.3's internal causes of business failure — poor management of cash flow and overestimation of sales are both named there — not a reproduction of any specific past-paper question.)
20 marks available
A cash-flow forecast shows money coming in and going out. If a bakery makes one, it will know if it is going to run out of money. This would stop it from failing.
Isolated recall of what a forecast shows, no application to a bakery specifically, and an unqualified leap straight to 'this would stop it from failing' with no reasoning connecting the two.
- Opening balance + net cash flow = closing balance = next month's opening balance.
- Net cash flow = inflows − outflows. A credit sale is revenue when invoiced, cash when received — rarely the same month.
- Budget: a financial plan agreed in advance. Historical-figures budgeting adjusts last period's figures; zero-based starts every line at £0.
- Variance = actual − budgeted. Does it raise or lower profit vs budget? Raises it = favourable, lowers it = adverse — one rule, every line.
- Always state the direction (favourable/adverse) and the £ or % — a correct number alone isn't complete.

Which of the following is a genuine LIMITATION of a cash-flow forecast, rather than one of its uses?
- AIt helps a business identify in advance which future month it may need an overdraft
This is a genuine USE of a cash-flow forecast — spotting a future shortfall early enough to arrange finance — not a limitation.
- BIt can support a loan or overdraft application by showing a lender when cash is needed
This is another genuine USE of a cash-flow forecast, demonstrating to a lender that a shortfall is understood and planned for — not a weakness of the technique.
- CIt shows the timing of cash inflows and outflows month by month
This describes what a cash-flow forecast IS and does — its basic function — not a shortcoming of it.
- It is built from estimates of future sales and costs, which can turn out to be wrong
Correct. A forecast is only as reliable as the assumptions feeding it — an inaccurate sales or cost estimate produces an inaccurate forecast, which is exactly why 'limitations' is its own named spec point alongside 'use'.
Traps tested: Confuses use with limitation
Which of the following is a genuine PURPOSE of a budget, as distinct from a difficulty of preparing one?
- Coordinating different departments' spending against a single, agreed financial plan
Correct. A budget gives every department a shared, agreed target to plan around, which is exactly what coordination means in this context — a genuine purpose the budget serves.
- BBudgets take time and management effort to prepare accurately
This is a genuine difficulty of budgeting, not a purpose — it describes a cost of the process, not something the process achieves.
- CDepartments may deliberately overstate what they need to make their own budget easier to hit
This describes 'budgetary slack' or padding — a real difficulty of budgeting caused by the incentives it creates, not a purpose of having a budget in the first place.
- DA budget set on inaccurate sales or cost forecasts will itself be inaccurate
This is a difficulty inherited from the same forecasting-uncertainty problem as cash-flow forecasts — a limitation, not something a budget is FOR.
Traps tested: Confuses purpose with difficulty
Harlow Bakes budgets its July ingredient costs at £2,750. Actual July ingredient costs are £2,950, because flour prices rose unexpectedly during the month.
Which of the following correctly calculates and explains the ingredient-cost variance for July, to the standard a 4-mark Calculate/Explain question on this paper actually credits?
- A£200 — costs were higher than expected this month
The number is correct but the direction (adverse) is never stated as the required business term, and there's no reasoning connecting it to profit — this is the 'variance would be affected' pattern that a confirmed examiner report says does not earn full marks.
- B£2,950, adverse — because this is the actual figure that was paid
This reports the actual cost itself, not the variance between actual and budgeted — a genuinely common calculation error, since £2,950 was never compared against the £2,750 target at all.
- £200, adverse — ingredient costs came in £200 higher than budgeted, which reduces actual profit below the budgeted figure
Correct. The number (£200), the unit (£), and the direction (adverse) are all present, and the reason ties the variance back to its effect on profit — exactly the AO1 knowledge, AO2 application (the £ figure), and AO3 analysis (the profit-impact reasoning) this tariff rewards.
- D£200, favourable — the business is investing more in higher-quality ingredients
The number is right but the direction is backwards: an unplanned cost increase reduces profit relative to budget, which is adverse by definition, regardless of what the extra spending might buy in quality terms.
Traps tested: Direction not stated as required term · Reports actual not variance · Direction reversed
In August, Harlow Bakes' opening cash balance is £600. Cash sales that month total £3,900. Credit sales invoiced in July, £4,600, are received in August. Cash outflows for August total £8,100, including a one-off £3,500 shop refurbishment.
Calculate Harlow Bakes' closing cash balance for August.
- A£400
This is the net cash flow for August (£8,500 total inflow − £8,100 outflow = £400) — but the question asks for the CLOSING BALANCE, which still needs the £600 opening balance added on top.
- B£8,500
This is the total cash inflow alone — it hasn't subtracted the £8,100 of outflows or added the opening balance, so it isn't a balance at all, just one half of the calculation.
- C−£2,900
This comes from subtracting the full £8,100 outflow from the £600 opening balance without ever including August's cash inflows — the inflow side of the forecast has been left out entirely.
- £1,000
Correct. Total inflow = £3,900 cash sales + £4,600 credit received = £8,500. Net cash flow = £8,500 − £8,100 = £400. Closing balance = opening £600 + net £400 = £1,000.
Traps tested: Stops at net cash flow · Reports inflow only · Omits inflows
A different bakery's four-month cash-flow forecast shows total cash inflow falling every month (£9,000, then £7,600, £6,300, £5,200), while net cash flow falls from +£1,200 in month 1 to −£1,800 in month 4, with no month recovering.
Which of the following correctly identifies the genuine problem this forecast reveals?
- AThe forecast might turn out to be wrong, since it's built on estimated figures
True in general, and a genuine limitation of any forecast — but it's a generic point that doesn't engage with what THIS forecast's own numbers actually show, which is what the question is asking about.
- Cash inflow is on a genuine declining trend and net cash flow has turned negative with no recovery in sight — the bakery needs to find ways to raise revenue or arrange finance to cover the shortfall
Correct. Both patterns are read directly from the numbers given (falling inflow month on month; a negative net cash flow that doesn't bounce back) and tied to the action each implies — exactly what a real 6-mark Analyse question on a cash-flow forecast's problems credits.
- CThis is the same kind of one-off timing dip as Harlow Bakes' oven purchase in March, so it isn't a real concern as long as the bakery stays profitable on paper
Harlow Bakes' March dip was a single month, driven by one named item, that fully recovered the next month. A trend that keeps falling for four months running, with no recovery, is a different pattern — treating it the same way over-applies the 'don't panic about one bad month' lesson to a case it was never meant to cover.
- DNet cash flow doesn't matter as long as the opening balance in month 1 was positive
The whole point of a forecast is tracking the balance forward month by month — a positive starting point says nothing about a balance that falls every month afterward.
Traps tested: Generic limitation not specific reading · Over generalises one off timing lesson · Ignores the trend

Profit, Liquidity and Business Failure
A firm's profit is one number; how profitable it is is a different one; and whether it's liquid enough to survive the next thirty days is a third question entirely — a firm can pass two of the three and still fail from the one it never checked.
