Transparent method
How this calculator works
- Subtract variable cost per unit from selling price to get contribution margin.
- Divide fixed costs by contribution margin and round required units up to a whole unit.
- Compare current volume with the unrounded break-even point to calculate margin of safety.
What the result does not include
- The model assumes price and variable cost remain constant as volume changes.
- Capacity limits, taxes, financing costs, and step-fixed costs are not included.
Common questions
What counts as a fixed cost?
Anything you pay whether or not you sell anything: rent, salaries, software, insurance. Variable costs scale with each unit — materials, shipping, payment processing, contractor time tied to delivery.
What is margin of safety?
How far sales can fall before you start losing money. Below 20% you are fragile: one lost client or one slow month puts you underwater.
