ACCT2019 Chap.7 Flexible Budgets and Variance Analysis
Flexible Budgets and Variance Analysis
Flexible budgeting separates the effect of actual activity from spending and efficiency. The static budget reflects planned volume; the flexible budget restates standard revenue and cost for actual output; actual results then reveal deviations in prices, quantities and overhead. Favourable and unfavourable describe benchmark direction, not management quality.
A useful variance answer calculates the amount, protects the sign and explains an operational cause that can be investigated. Price or rate variance values the actual input quantity at the difference between actual and standard price. Efficiency variance values the quantity difference against the standard allowed for actual output. The pair should reconcile to actual cost less standard cost allowed.
Variable overhead follows its driver, while fixed-overhead production-volume variance reflects denominator capacity rather than a direct cash overspend. Standards must remain attainable and current, and investigation should focus on material patterns with evidence about purchasing, quality, labour, process and capacity.
Managers should examine related variances together because one operational choice can improve price while worsening usage, or raise labour rate while reducing hours. The reconciliation locates the net effect before cause is assigned. Investigation becomes credible when the report names the source record, operational owner and paired variance needed to test the proposed cause.

Separating material price and efficiency
- +2AskSia self-assessment split, not official marks. Price variance is 6,650 x ($7.20 - $7.50) = $1,995 favourable.
- +2Efficiency variance is $7.50 x (6,650 - 6,400) = $1,875 unfavourable.
- +1The net flexible-budget effect is $120 favourable, but the offsetting components require investigation.
Key terms
- Static Budget
- The original budget based on the planned level of activity.
- Flexible Budget
- Standard revenue and cost recalculated for the actual activity achieved.
- Price Variance
- The cost effect of actual input price differing from standard price.
- Efficiency Variance
- The cost effect of actual input quantity differing from the standard quantity allowed.
- Production-volume Variance
- A fixed-overhead allocation variance caused by output differing from denominator capacity.
Flexible Budgets and Variance Analysis FAQ
Why compare actual results with a flexible budget?
It holds actual output constant and therefore avoids blaming cost changes on volume alone. The remaining difference is more informative about input price, usage, spending or efficiency than a direct actual-versus-static comparison.
Does favourable always mean good performance?
No. A lower purchase price can reduce quality and create waste; higher labour rates can buy skill that saves hours. The label reports direction against standard, while operational evidence determines whether the outcome is desirable and sustainable.
How are price and efficiency variances connected?
Price uses actual quantity because every unit acquired or used experiences the price difference. Efficiency values excess or saved quantity at standard price. Reviewing both prevents one favourable component from hiding an unfavourable total or quality trade-off.
Exam move
Draw the static-to-flexible-to-actual bridge before applying formulas. Practise identifying whether a question concerns volume, input price, input quantity, variable overhead or fixed overhead. For direct inputs, write AQ, AP, SP and SQ allowed with units; this exposes whether a number is a price, quantity or output standard.
Predict favourable or unfavourable from plain language, calculate, then reconcile the paired components to the flexible-budget variance. Keep a list of realistic causes and the manager most able to investigate each one, while avoiding automatic blame. Refresh standards when process, technology or market conditions change. A variance becomes useful only when its amount, direction, cause and action are distinguished.
Build a variance matrix with formula, direction test, likely evidence and responsible process for material, labour and overhead. Use one case where a favourable price pairs with unfavourable efficiency and another where higher labour rates buy enough skill to create favourable time. Reconcile the pair to actual cost minus standard cost allowed so swapped quantities cannot survive.
For fixed overhead, keep spending and production-volume effects separate: one compares actual with budgeted fixed cost, while the other reflects output relative to denominator capacity. Explain why the latter is not automatically a cash overspend. End each drill with an investigation plan naming the operational record, supplier fact or production condition needed to distinguish correlation from cause.
