Unit Economics

AdvancedAlso: Per-Unit Cost Accounting
In briefUnit economics relate revenue and costs per unit, such as customer or order. They show whether a single unit delivers a contribution margin and whether scaling makes the model more profitable. Negative values mean additional growth tends to enlarge losses.

Definition

Unit economics describe revenue and costs per clearly defined unit, such as per customer, order, or subscription. They show whether a single unit, viewed in isolation, delivers a contribution margin. This makes it possible to assess whether a business model becomes more profitable with scaling or enlarges losses.

How it is calculated

Formula. Contribution margin per unit = revenue per unit − variable costs per unit

Why it matters for small caps

Young small caps often grow quickly without the per-unit economics holding up. Negative unit economics indicate that growth enlarges the loss rather than creating value.

Common misreadings

  • Positive unit economics per customer do not automatically mean overall profitability, since fixed costs and overheads are left out.

Frequently asked

Which unit is considered in unit economics?
It depends on the model: for subscriptions the individual customer, in retail the order, on platforms the transaction. A consistent and traceable definition is important.
What do negative unit economics indicate?
They indicate that each additional unit fundamentally generates a loss. Without cost cuts or price increases, more volume then worsens the problem.
Are good unit economics enough for a viable model?
No. They are necessary but not sufficient, because fixed costs, administration, and cost of capital must also be covered.
