Planning and Operational Variances Explained for ACCA PM
Planning variances measure the effect of an unrealistic original standard. Operational variances measure how well managers performed against a revised, realistic standard. You revise the standard to what it should have been in hindsight (the ex-post standard), then split the total variance between planning and operational, and report each to the person responsible.
What this chapter covers
Standard costing in the earlier chapters compares actual results with the original budget. That comparison has a flaw. If the original standard was out of date, the variance blames the manager for something they could not control. This chapter fixes that by splitting each variance into two parts: a planning variance (original standard versus revised standard) and an operational variance (revised standard versus actual).
You apply the same idea to materials, labour and sales. For sales, the total sales volume variance is split into a planning variance (original budget versus revised budget, for example because the market size changed) and an operational variance (revised budget versus actual). The planning sales variance is the market size variance, and the operational sales variance is the market share variance. Market conditions are outside the sales team's control, so the market size variance sits in the planning part, while the market share variance reflects the team's performance. Each one needs a clear ex-post figure, a clear order of calculation and a clear sign (favourable or adverse).
The chapter links to basic variance analysis, budgeting and performance reporting elsewhere in PM. It also feeds the written side of the paper. You may be asked to calculate the variances in a Section C question, then explain which are controllable, who is responsible and whether the standard should change. Objective test questions often test one single calculation or one interpretation point.
Variances are a regular feature of PM, and this chapter is where they become more advanced. Calculation marks are easy to win if you follow a fixed layout, and the objective test items are all or nothing, so a clean method protects you from careless slips. Section C questions also reward the discussion: saying who is accountable and whether a variance is controllable earns marks that many students miss. If you master this chapter, you also strengthen your understanding of standard costing, sales variances and performance reporting.
Planning and operational variances: topics in the order to study them
- 1Planning and Operational Variances BasicsStart here to learn the core idea: the original standard may be unrealistic, so the total variance has two parts with two different owners.
- 2Revising Standards and Ex-Post BudgetsEvery calculation depends on the revised (ex-post) standard, so you must know how to build it before you split any variance.
- 3Material Planning and Operational VariancesMaterials are the simplest worked case, with price and usage variances, so you practise the split on a familiar pattern.
- 4Labour Planning and Operational VariancesLabour repeats the same method with rate and efficiency, which cements the layout after materials.
- 5Sales Variances: Market Size and Market ShareSales need a different split, so learn it after the cost variances when the planning and operational logic is already clear.
- 6Interpreting and Reporting Planning and Operational VariancesFinish with interpretation, because it needs all the calculations behind it and is what Section C discussion parts test.
How to prepare Planning and operational variances
Treat this chapter as one method applied several times. Learn the logic first, then drill the layout until it is automatic.
- Write the idea in one sentence: planning variance = original standard versus revised standard; operational variance = revised standard versus actual.
- Practise building the revised standard from information in the question, such as a new price or a new time per unit, before doing any variance.
- Calculate materials in a fixed layout: original standard, revised standard, actual. Check that planning plus operational equals the traditional total variance.
- Repeat the same layout for labour, then change only the inputs. Always state favourable or adverse.
- Learn the sales split on its own: set out budgeted and actual market size and share, then calculate each variance in the same order every time.
- Practise written parts: for each variance, state its cause, who is responsible, whether it is controllable and what management should do.
- Finish with timed mixed questions, both objective test cases and a full Section C question, and review every sign error.
Common mistakes in Planning and operational variances
Using the original standard instead of the revised standard for the operational variance.
Fix: Write the three columns first: original, revised, actual. Operational variances sit between the last two only.
Getting the sign wrong on the planning variance.
Fix: Ask whether the revised standard leads to higher or lower profit than the original. Higher profit is favourable, lower is adverse.
Not checking that planning plus operational equals the total variance.
Fix: Always add the two parts and compare them with the traditional variance. If they differ, find the error before moving on.
Mixing up market size and market share variances.
Fix: Learn one fixed layout and use it every time. Size asks what the market did; share asks how the business did within it.
Giving a calculation without interpretation when the question asks for comment.
Fix: For each variance, state the likely cause, who is responsible, whether it is controllable, and one action management could take.
Revising a standard when the question gives no basis for it.
Fix: Only treat a variance as planning when the question shows that the standard should have been different, for example a market-wide price change.
Last-day revision: Planning and operational variances
- Planning variance: original standard compared with revised (ex-post) standard.
- Operational variance: revised standard compared with actual result.
- Planning plus operational equals the traditional total variance, so use this as a check.
- Planning variances are usually not the operating manager's responsibility.
- Operational variances show how well managers performed against a realistic standard.
- Always use the revised standard as the base for operational variances.
- Keep a consistent sign rule: more profit or lower cost than expected is favourable.
- The sales volume variance splits into a planning variance (original budget versus revised budget, for example from a change in market size) and an operational variance (revised budget versus actual). The planning sales variance is the market size variance, and the operational sales variance is the market share variance.
- Market size variance is the planning variance and is usually treated as uncontrollable by the sales team.
- Market share variance is the operational variance and reflects the sales team's performance against the market.
- A large planning variance suggests the original standard was poorly set.
- Objective test answers are all or nothing, so check units, signs and the base used.

Planning and operational variances: frequently asked questions
What is the difference between planning and operational variances?
A planning variance is the gap between the original standard and the revised standard, and reflects poor or outdated planning. An operational variance is the gap between the revised standard and the actual result, and reflects how well managers performed.
Who is responsible for a planning variance?
Usually the people who set the standard, often senior management or budget setters, rather than the operating manager. Operational variances are normally the responsibility of the manager running the activity.
What is an ex-post budget?
It is a budget revised with hindsight to reflect the conditions that actually applied, such as a changed market price. It is the realistic base used to judge operational performance.
How are these variances tested in the PM exam?
They can appear in objective test questions that ask for one calculation or one interpretation, and in Section C questions that ask you to calculate variances and comment on them. Practise both forms.
