Methodology and assumptions
Contribution margin = price − variable cost. Break-even units = ⌈fixed costs ÷ contribution margin⌉; target-profit units = ⌈(fixed + target profit) ÷ contribution margin⌉. Margin of safety = (expected − break-even units) ÷ expected. Degree of operating leverage = total contribution ÷ operating profit at expected volume. Discount volume = units needed at the discounted price to earn the same profit as expected volume at full price. A non-positive contribution margin never breaks even.
