2009 Foster School of Business Cost Accounting L.DuCharme 1 Direct Input Variances, and Management Control: I Chapter 7

2009 Foster School of Business Cost Accounting L.DuCharme 2 Overview Standards Variances Static vs. Flexible budgets Calculate variances for direct inputs (DM & DL) EoP Adjustments When to investigate variances

2009 Foster School of Business Cost Accounting L.DuCharme 3 Standard = Budget Here budgeted amount = standard amount. We will use these terms interchangeably in this course.

2009 Foster School of Business Cost Accounting L.DuCharme 4 Variances Variance = budgeted – actual results If operating income is greater than expected (budget), then you have a favorable variance. Not all favorable variances are “good.”

2009 Foster School of Business Cost Accounting L.DuCharme 5 Static and Flexible Budgets Static Budget Planned level of output at start of the budget period Based on Flexible Budget Budgeted revenues and cost based on actual level of output Based on

2009 Foster School of Business Cost Accounting L.DuCharme 6 Example Calculate Variances

2009 Foster School of Business Cost Accounting L.DuCharme 7 Useful Format to Calculate DM and DL Variances Actual “Noname” Flexible Static Results Budget BudgetBudget Actual input Actual inputFlex-budget input Static-budget input X X X X Actual price Budget price Budget price Budget price 0,1 | Static Budget Var | 2 |----- Flexible Budget Var | -- Sales Volume Var. -- | 3 |---- Price ---- | ---- Usage ---- |

2009 Foster School of Business Cost Accounting L.DuCharme 8 Price Variance: material Direct-material price variance Actual price – Budgeted price × Actual Quantity used =

2009 Foster School of Business Cost Accounting L.DuCharme 9 Price Variance: labor Direct-labor price variance Actual price – Budgeted price × Actual Quantity used =

2009 Foster School of Business Cost Accounting L.DuCharme 10 Efficiency Variance: DM Direct-material efficiency variance Actual quantity – Standard quantity × Standard price =

2009 Foster School of Business Cost Accounting L.DuCharme 11 Efficiency Variance: labor Direct-labor efficiency variance Actual quantity – Standard quantity × Standard price =

2009 Foster School of Business Cost Accounting L.DuCharme 12 Example: calculate variances The Boing Company (largest maker of toy airplanes) has provided you with the following data on burppa wood costs for Burppa wood rots very fast. All wood is used in the period in which it is purchased. Actual Budgeted Toy planes (units)10,0009,000 Input (bd. ft.)5,2004,500 Price ($/bd. ft.)$0.49$0.50

2009 Foster School of Business Cost Accounting L.DuCharme 13 Calculation of Variances Please calculate the five variances for burppa wood: –Static-budget variance –Flexible-budget variance –Sales-volume variance –Price variance –Usage (efficiency) variance

2009 Foster School of Business Cost Accounting L.DuCharme 14 Performance Measurement Using Variances Effectiveness is the degree to which a predetermined objective or target is met. Efficiency is the relative amount of inputs used to achieve a given level of output. Variances should not solely be used to evaluate performance.

2009 Foster School of Business Cost Accounting L.DuCharme 15 End-of-period Adjustments Variance accounts are disposed of using one of the approaches outlined in chapter 4. –W/O all to CoGS –Prorate to CoGS, FG, & WIP based on: Ending total $ amount in accounts. $ amount of IDCost in the respective accounts. (Over- or under-allocated overhead is a variance)

2009 Foster School of Business Cost Accounting L.DuCharme 16 When to Investigate Variances When should variances be investigated? Subjective judgments Rules of thumb as “investigate all variances exceeding $10,000 or 25% of expected cost, whichever is lower.”
