Variable costing versus absorption costing. The Mavis Company uses an absorption-costing sys- tem based on standard costs. Total variable manufacturing cost, including direct material cost, is $3 per unit; the standard production rate is 10 units per machine-hour. Total budgeted and actual fixed manufacturing overhead costs are $420,000. Fixed manufacturing overhead is allocated at $7 per machine-hour ($420,000 ÷ 60,000 machine-hours of denominator level). Selling price is $5 per unit. Variable operating (nonmanufactur- ing) cost, which is driven by units sold, is $1 per unit. Fixed operating (nonmanufacturing) costs are $120,000. Beginning inventory in 2012 is 30,000 units; ending inventory is 40,000 units. Sales in 2012 are 540,000 units. The same standard unit costs persisted throughout 2011 and 2012. For simplicity, assume that there are no price, spending, or efficiency variances.

Required: Graph how fixed manufacturing overhead is accounted for under absorption costing. That is, there will be two lines: one for the budgeted fixed manufacturing overhead (which is equal to the actual fixed manufacturing overhead in this case) and one for the fixed manufacturing overhead allocated. Show how the production-volume variance might be indicated in the graph.
