APPLY THE CONCEPTS: Calculate the break-even point in sales dollars for Lennon Hardware Further analysis of Lennon Hardware's fixed costs revealed that the company actually faces annual fixed overhead costs of $4,200 and annual fixed selling and administrative costs of $1,800. Variable cost estimates are correct: direct materials cost, $12.00 per unit; direct labor costs, $15.00 per unit; and variable overhead costs, $3.00 per unit. At this time, the selling price of $40 will not change. Complete the following formulas for the revised fixed costs. Enter the ratio as a percentage. Contribution Margin per Unit = $ 40 30 10 Contribution Margin Ratio = $ 10 25 % 40 Now complete the formulas for (1) the break-even point in sales dollars and (2) the units sold at the break-even point. To calculate this, divide the break-even point in sales dollars by the unit selling price. Break-Even Point in Sales Dollars = $ 6,000 24,000 25 V % Units Sold at Break-Even Point 600 V units Assume that the number of units that Lennon sold exceeded the break-even point by one (1). How much would operating income be? $ What would operating income be if the units sold exceeded the break-even point by five (5) units? $
