Operating Statements and Variance Interpretation in ACCA Management Accounting

Updated 11 October 2026 · Fact-checked

An operating statement reconciles budgeted profit to actual profit by listing each variance. Start with budgeted profit, add favourable variances, deduct adverse ones, and reach actual profit. Then explain each variance, and check whether linked variances, such as a cheap material price and poor usage, share one cause.

Understand Operating Statements and Variance Interpretation

A standard costing system sets a budgeted profit. At the end of the period, actual profit is almost always different. An operating statement (also called a reconciliation statement) explains the gap, one variance at a time.

Think of it as a bridge. You start at budgeted profit on one side and finish at actual profit on the other. Each variance is a plank. A favourable (F) variance increases profit. An adverse (A) variance reduces profit. If you add and subtract them correctly, you land exactly on actual profit.

The statement is only half the job. Management wants to know why. Each variance has possible causes, and some causes are shared. Buying cheap, poor-quality material may give a favourable price variance but an adverse usage variance, and an adverse labour efficiency variance too. These are interrelated variances. Judge them together, not alone.

MA questions in Section A usually ask you to complete one line of the statement, pick the likely cause of a variance, or choose which variances are linked. Section B can ask you to prepare the whole statement and comment on it. Be clear about which costing basis is used: under absorption costing, the fixed overhead volume variance appears. Under marginal costing, it does not.

Key formulas to remember

Operating statement (absorption costing): Budgeted profit ± sales variances ± cost variances = actual profit; Favourable variances add to profit. Adverse variances reduce it.
Sales volume variance (profit basis): (Actual units sold − budgeted units) × standard profit per unit; Absorption costing uses standard profit per unit. Marginal costing uses standard contribution per unit.
Sales price variance: (Actual price − standard price) × actual units sold; Higher actual price is favourable.
Material price variance: (Standard price − actual price) × actual quantity purchased or used; Use quantity purchased if materials are valued at standard on purchase. Read the question.
Material usage variance: (Standard quantity for actual output − actual quantity used) × standard price; Using less than standard is favourable.
Labour rate variance: (Standard rate − actual rate) × actual hours paid; Lower actual rate is favourable.
Labour efficiency variance: (Standard hours for actual output − actual hours worked) × standard rate; Fewer hours than standard is favourable.
Idle time variance: Idle hours × standard rate (always adverse); Efficiency is then calculated on hours worked, not hours paid.
Variable overhead variances: Expenditure: (standard rate × actual hours) − actual cost. Efficiency: (standard hours − actual hours) × standard rate; Efficiency uses the same hours difference as labour efficiency.
Fixed overhead variances: Expenditure: budgeted − actual fixed overhead. Volume: (actual output − budgeted output) × standard fixed overhead per unit; Volume applies in absorption costing only. It is favourable when output exceeds budget.
Sign rule: Actual cost lower than standard = F. Actual revenue higher than standard = F; Reverse for adverse.

How to solve Operating Statements and Variance Interpretation questions

Use this order for any operating statement or interpretation question.

1Read the costing basis: absorption or marginal. This decides the sales volume and fixed overhead lines.
2Write down budgeted profit and actual profit if given. These are your two end points.
3Calculate each variance and mark it F or A. Check the sign with common sense: did you pay less, use less, or sell for more?
4List the variances under the headings given: sales, materials, labour, variable overheads, fixed overheads.
5Add favourable and deduct adverse variances from budgeted profit. Compare the result with actual profit. If it differs, find the arithmetic or sign error.
6For interpretation, state the cause in plain business words, such as poor-quality material, untrained staff or a machine breakdown.
7Look for links. Does one decision explain two variances? Say so, and say whether the net effect is good or bad.
8Check the answer type. Number entry needs the figure and, if asked, the F or A label. Multiple response needs exactly the stated number of choices.

Quickest way: Sign-first reconciliation shortcut

When to use it: Use for Section A questions that give some variances and ask for the missing one or for actual profit.

Turn every variance into a signed number: F as +, A as −.
Add all signed variances to budgeted profit to get actual profit.
If one variance is missing, use: missing variance = actual profit − budgeted profit − the sum of the other signed variances.
The sign of your answer gives F (positive) or A (negative).
For cause questions, scan the options and choose the one that explains the direction of the variance. Then test any 'linked' option by asking if one action could cause both.

Common mistakes in Operating Statements and Variance Interpretation

Adding adverse variances and deducting favourable ones.
Students think 'adverse' means a number to add, as with costs.
Fix: Always think in profit terms. Adverse reduces profit. Favourable increases it. Write + and − beside each variance.
Including the fixed overhead volume variance in a marginal costing statement.
Students copy the absorption layout without checking the basis.
Fix: Under marginal costing, fixed overhead is a period cost. Only the fixed overhead expenditure variance appears, and sales volume uses contribution.
Using standard profit per unit when contribution is needed, or the reverse.
The sales volume formula looks the same for both bases.
Fix: Tick the basis first. Absorption: standard profit. Marginal: standard contribution.
Explaining each variance in isolation.
Students memorise one cause per variance.
Fix: Ask whether a favourable variance was bought at the cost of an adverse one elsewhere, for example cheap material and high wastage, or overtime premium paid to hit extra volume.
Treating a favourable variance as automatically good.
The label 'favourable' sounds positive.
Fix: A favourable usage variance from rushed work may cause quality failures. Comment on the cause before judging.
Reaching a reconciled profit that does not match actual profit and ignoring it.
Time pressure and no final check.
Fix: Always compare your final line with actual profit. A mismatch means a wrong sign, a missed variance or the wrong quantity base.

Worked examples

Example 1

Budgeted profit is $50,000. Variances: sales price $4,000 F; sales volume $6,000 A; material price $2,500 F; material usage $3,500 A; labour rate $1,200 A; labour efficiency $2,000 F; fixed overhead expenditure $800 A. Calculate actual profit.

Show the solution

Favourable variances: 4,000 + 2,500 + 2,000 = $8,500.
Adverse variances: 6,000 + 3,500 + 1,200 + 800 = $11,500.
Net variance = 8,500 − 11,500 = $3,000 adverse.
Actual profit = 50,000 − 3,000 = $47,000.

Answer: Actual profit is $47,000.

Example 2

A firm budgeted to make and sell 1,000 units at a standard material cost of 4 kg at $5 per kg. It made and sold 1,000 units. It bought and used 4,400 kg at a total cost of $20,680. Calculate the material price and usage variances, then suggest one cause of the pair and say why they may be linked.

Show the solution

Standard quantity for actual output = 1,000 × 4 = 4,000 kg.
Usage variance = (4,000 − 4,400) × $5 = $2,000 adverse.
Price variance = (4,400 × $5) − $20,680 = $22,000 − $20,680 = $1,320 favourable.
Net material variance = 2,000 A − 1,320 F = $680 adverse.
Link: buying cheaper, lower-quality material could give the lower price but more waste or defects, so more material is used.

Answer: Material price $1,320 F; material usage $2,000 A. A likely shared cause is cheaper, lower-quality material. The saving on price was smaller than the extra usage cost, so the net effect is $680 adverse.

Exam tips

Check the costing basis in the first line of the question. It decides whether the fixed overhead volume variance appears.
In number entry questions, enter the figure the way the question asks. If it asks for F or A, include it, and do not add commas or symbols if the box does not need them.
For 'which variances are likely to be linked' questions, look for pairs where one action pushes the two in opposite directions, such as price and usage, or rate and efficiency.
In multiple response questions, select exactly the number of options stated. Do not tick an extra 'plausible' cause.
Always check the reconciliation total against actual profit. It is the fastest way to catch a wrong sign.

ACCA Applied SkillsOperating Statements and Reconciling Budget to Actual Profit

Operating Statements and Variance Interpretation: frequently asked questions

What is an operating statement in management accounting?

It is a statement that starts with budgeted profit and adjusts it for each variance to reach actual profit. It shows where and why performance differed from plan. It is also called a reconciliation statement.

How do I treat favourable and adverse variances in the reconciliation?

Add favourable variances to budgeted profit because they increase profit. Deduct adverse variances because they reduce profit. The final figure must equal actual profit.

What are interrelated variances?

They are variances with a common cause, so one is often favourable while the other is adverse. A common example is a favourable material price variance with an adverse usage variance after buying cheaper material. Another is an adverse labour rate variance with a favourable efficiency variance after using more skilled staff.

Does the operating statement look different under marginal costing?

Yes. The sales volume variance uses standard contribution, not standard profit. There is no fixed overhead volume variance, and only the fixed overhead expenditure variance appears.
