Common questions

What is the break-even point?

The volume at which revenue exactly covers all costs (fixed + variable). Below this volume = loss. Above = profit. The single most important number every owner must know.

How do you compute contribution per unit?

Contribution = sale price − variable cost. This is the amount each unit "contributes" to covering fixed costs (and after that, profit). Example: price ₪100, variable cost ₪40 → contribution ₪60.

What is a healthy margin of safety?

Margin of safety = (current units − break-even units) / current units. Below 20% = risky; small drop wipes out profit. 20-40% = OK. Above 40% = healthy.

What's the difference between fixed and variable costs?

Fixed = paid regardless of volume: rent, fixed salary, insurance. Variable = paid per unit: materials, sales commission, packaging. Correct classification is the first step.
