How to Calculate Unit Economics
Formula
Contribution Per Unit = Selling Price - COGS - Operating Cost - Acquisition Cost Unit Margin = Contribution / Selling Price x 100
Unit economics answers the fundamental business question: do you make money on each sale? Positive unit economics means you earn profit on every transaction and can scale profitably. Negative unit economics means scaling only accelerates losses. Startups sometimes operate with negative unit economics temporarily to capture market share, but eventually every unit sold must contribute positive margin.
Exemple Résolu
A product sells for $120. COGS is $40, allocated operating cost is $30, and acquisition cost is $15 per unit.
- 01Gross Profit = $120 - $40 = $80
- 02Contribution = $120 - $40 - $30 - $15 = $35
- 03Unit Margin = ($35 / $120) x 100 = 29.2%
Questions Fréquentes
When do unit economics matter most?
At every stage. Before launch, to validate the business model. At scale, to ensure growth is profitable. When fundraising, investors scrutinize unit economics to assess whether scaling will create value or destroy it.
What if unit economics are negative?
Identify the cause. Is COGS too high? Negotiate supplier pricing or find alternatives. Is acquisition cost too high? Optimize marketing channels. Are operating costs bloated? Streamline operations. If none can be improved enough, your pricing may need to increase.
