How to use

Enter your fixed costs (e.g., rent, equipment), variable cost per unit (materials, labor), and selling price per unit. The calculator instantly shows:

  • Break‑even units: Number of units you must sell to cover all costs.
  • Break‑even revenue: Total sales dollars needed to break even.
  • Contribution margin: Amount each unit contributes to covering fixed costs and profit.
  • Contribution margin ratio: Percentage of each sales dollar available to cover fixed costs.

Use this tool for pricing decisions, evaluating new ventures, or setting sales targets.

Break‑even formulas

Contribution Margin = Selling Price − Variable Cost per Unit

Break‑even (units) = Fixed Costs ÷ Contribution Margin per Unit

Break‑even (revenue) = Fixed Costs ÷ Contribution Margin Ratio

Contribution Margin Ratio = (Selling Price − Variable Cost) ÷ Selling Price

These formulas assume linear cost and revenue functions. Results are estimates; actual business conditions may vary.

Frequently asked questions

What is the break‑even point?

The break‑even point is the level of sales at which total revenue equals total costs, resulting in zero profit or loss. It's a critical metric for business viability.

What are fixed vs. variable costs?

Fixed costs remain constant regardless of production volume (e.g., rent). Variable costs change directly with the number of units produced (e.g., materials).

Can I use this for services or subscription models?

Yes. For services, "units" can be billable hours, customers, or subscriptions. Adjust your variable cost per unit accordingly.

Why does contribution margin matter?

Contribution margin shows how much each unit helps cover fixed costs. A higher contribution margin means you reach break‑even faster.
