What is contribution per unit?

Selling price minus variable cost per unit. It covers fixed costs first and then becomes profit.

Why can break-even be impossible?

If selling price is not higher than variable cost, each sale cannot contribute toward fixed costs.

What is margin of safety?

Expected units above the break-even volume.

Does the model include step-fixed costs?

Only the fixed cost entered. Add or scenario-test capacity-related cost increases separately.

About the Break-even Scenario Studio

Break-even Scenario Studio shows how price, variable cost and fixed costs interact before a business earns profit. It calculates contribution per unit, break-even units and the revenue required to cover the entered cost structure.

Downside, expected and upside volume inputs make the analysis useful for planning rather than presenting one isolated answer. The report highlights expected profit or loss and the margin of safety above break-even.

The model assumes linear unit economics. Review capacity constraints, step-fixed costs, mix changes and working-capital needs separately.
