Quick Calculation Tools​

Break-Even Point​

Break-Even Units = Fixed Costs ÷ (Selling Price - Variable Cost per Unit)

Break-Even Sales = Fixed Costs ÷ Contribution Margin Ratio

Contribution Margin = Selling Price - Variable Cost

Contribution Margin Ratio = Contribution Margin ÷ Selling Price

Markup vs. Margin​

Markup % = (Selling Price - Cost) ÷ Cost × 100

Margin % = (Selling Price - Cost) ÷ Selling Price × 100

Example:​

  • Cost: €80
  • Selling Price: €100
  • Markup: (€100 - €80) ÷ €80 = 25%
  • Margin: (€100 - €80) ÷ €100 = 20%
