Frequently asked questions
- What is contribution margin?
- Contribution margin is the selling price minus variable cost per unit. Each unit sold above break-even contributes this amount to profit.
- What are fixed vs. variable costs?
- Fixed costs don't change with production volume (rent, insurance, salaries). Variable costs scale with units sold (materials, commissions, packaging).
