Bluestone Systems Corp. is a mid-sized manufacturer of industrial-grade network switching units, serving enterprise clients across the healthcare and logistics sectors. Management wants to analyze the company's profitability at current production levels and determine the break-even point to better understand operational risk. With fixed costs of $1,006,000 and actual sales of 34,800 units at $1,080 each, the finance team must calculate contribution margin, net income, CM ratio, break-even units, and break-even sales dollars.

Correct Answers

net Income

$20,744,000.00

break Even Sales

$1,738,368.00

break Even Units

1,610

contribution Margin Per Unit

625

Step-by-Step Solution

MIXED PROBLEM — Contribution Margin + Break-Even

CONTRIBUTION MARGIN INCOME STATEMENT:
  Sales (34,800 units × $1,080.00)         $37,584,000.00
  Less: Variable Costs (34,800 × $455.00) $15,834,000.00
  ─────────────────────────────────────────────────────────
  Contribution Margin                                   $21,750,000.00
  Less: Fixed Costs                                     $1,006,000.00
  ─────────────────────────────────────────────────────────
  Net Income                                            $20,744,000.00

Per Unit:
  CM per Unit = $1,080.00 − $455.00 = $625.00
  CM Ratio    = $625.00 ÷ $1,080.00 = 57.87%

BREAK-EVEN ANALYSIS:
  Break-Even Units = Fixed Costs ÷ CM per Unit
  Break-Even Units = $1,006,000.00 ÷ $625.00 = 1609.6000 → 1610 units (rounded up)

  Break-Even Sales = Fixed Costs ÷ CM Ratio
  Break-Even Sales = $1,006,000.00 ÷ 57.8704% = $1,738,368.00
