Transparent method

How this calculator works

  1. Subtract variable cost per unit from selling price to get contribution margin.
  2. Divide fixed costs by contribution margin and round required units up to a whole unit.
  3. 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.
