Connection to Other Chapters Chapter 13 extends the price and quantity variances to overhead and marketing. Chapter 12 began the price and quantity variance analysis with direct labor and direct materials. Chapter 9 described how absorption costing applies overhead to jobs. Chapter 4 built the foundation on how internal accounting is used for decision control.

Overhead Volume Measures BV: Budgeted volume (also known as denominator volume) Estimated at the beginning of the year and used for calculating the overhead rate SV: Standard volume (also known as earned or allowed volume) (Output units completed)  (Standard input hours per output unit) Volume used to apply overhead to work-in-process inventory AV: Actual volume Actual hours or other input resource used during period

Budget Volume Estimates Estimated budget volume influences overhead rate. Increasing budgeted volume (denominator) while holding total budgeted dollars constant (numerator) decreases the overhead rate. Expected volume to set budget Adjust expectation based on number of units forecast for next year. Rises and falls with business cycle Normal volume to set budget Forecast of long-run average annual production Does not change during business cycle

Flexible Overhead Budget Flexible overhead budget is the formula for budget forecast. Flexible overhead budget = FOH + (VOH  V) = $1,350,000 + ($14  V) Estimate budgeted overhead (BOH) dollars using a specific budgeted volume number (BV) and the flexible overhead budget formula. BOH = FOH + (VOH  BV) = $ 1,350,000 + ($14  67,500 hours) = $ 2,295,000

McGraw-Hill/Irwin Accounting for Decision Making and Control, 5/e © 2006 The McGraw-Hill Companies, Inc., All Rights Reserved. Overhead Rate Overhead rate is the total budgeted overhead dollars for the year divided by the budgeted volume for the year. OHR = (BOH  BV) = (FOH  BV) + VOH The overhead rate consists of the estimated: fixed overhead $ per input hour (FOH  BV), and variable overhead $ per input hour (VOH)

McGraw-Hill/Irwin Accounting for Decision Making and Control, 5/e © 2006 The McGraw-Hill Companies, Inc., All Rights Reserved. Overhead Absorbed Overhead is absorbed (also known as applied) by the product when work is done in the factory. The accounting system transfers costs from the overhead account to the work-in-process account (Figure 9-1). For most firms, overhead is absorbed using the standard volume. Overhead absorbed = Overhead rate  Standard volume = OHR  SV Standard Volume = Units of output  Standard input per output See Table 13-5: SV = 67,400 machine hours for 96,000 blocks Overhead absorbed = $34  67,400 machine hours

Total Overhead Variance Overhead variances occur when the actual overhead incurred does not equal the overhead absorbed (see Figure 9-1 and the T-accounts).

Rewarding favorable volume variances encourages inventory building.

Inaccurate Flexible Budget Usefulness of overhead variances in performance measurement depends on accuracy of flexible budget in predicting cost-volume relation. Flexible budget assumes a linear formula over relevant range. But as production volume increases to levels near or above plant capacity, congestion occurs and: -actual costs increase above flexible budget. -unfavorable spending variance is reported. A more accurate flexible budget formula would forecast congestion costs, and allow variable costs to increase as volume increases.
