Common mistakes

⚠️ Not accounting for step-fixed costs that change at certain volumes
⚠️ Assuming variable costs remain constant at all production levels
⚠️ Forgetting that break-even doesn't include desired profit margin

Worked example

Finding break-even units for product with €12,fixed costs, €price, and €variable cost.

Sell unites of {unites} to break even, generating facturacion of {facturacion}. Each unit contributes margen_contribucion of {margen_contribucion}.
