Contribution margin connects sales to profit
Each sale contributes its price minus variable cost toward fixed costs. After fixed costs are covered, additional contribution becomes operating profit before taxes and costs not included in the model.
Use a downside scenario
- Reduce the selling price to test discounting pressure.
- Increase variable costs to reflect supplier or delivery changes.
- Use a cautious sales volume rather than the best possible month.
- Include owner compensation when it is a real operating requirement.
