Unit economics

Measure revenue and directly attributable costs for one defined unit before using scale assumptions in an investment case.

Quick answer

Unit economics measures the revenue, direct cost and contribution associated with a defined unit such as a customer, order, product, location or deployed asset. The useful unit and cost perimeter depend on the business model and must be stated before results are compared.

Use the worked example

Meaning and transaction use

An SEC-filed presentation illustrates customer unit economics through acquisition cost, monthly subscription contribution and payback, with stated margin assumptions. [S1]

Another SEC filing presents retail unit economics as wholesale price less production and shipping costs, showing how the unit and cost perimeter can differ by channel. [S2]

Proposed control method: reconcile per-unit inputs to financial records and report current observed economics separately from scale scenarios.

Worked example

Illustrative order economics only. Assume revenue of 120 per order, product cost of 48, fulfilment of 14, payment fees of 4 and variable support of 6.

Scroll the table horizontally to view all columns.

Measure	Calculation	Result
Revenue per order	Given	120
Variable cost per order	48 + 14 + 4 + 6	72
Contribution per order	120 - 72	48
Contribution margin	48 / 120	40.0%

Illustrative contribution is 48 per order, equal to a 40.0% contribution margin under the stated cost perimeter.

Proposed transaction review process

Define the unit

Choose the customer, order, product, location or asset basis.

Set the perimeter

Classify revenue, variable costs and excluded shared costs.

Reconcile evidence

Tie volume, revenue and costs to operating and finance records.

Test scale

Model price, utilisation, mix and marginal cost scenarios.

Evidence checklist

Volume

Units delivered, active customers, orders or deployed assets.

Revenue

Price, discounts, refunds, usage and product mix.

Costs

Product, fulfilment, service, payment and other variable costs.

Scale

Capacity, utilisation, supplier terms and observed learning effects.

Decision framework

Situation	Proposed action
Contribution is negative	Identify price, cost, mix or service changes before scaling.
Economics vary by channel	Report channel-specific units and margins.
Scale benefits are forecast	Label assumptions and retain a downside case.
Acquisition costs are high	Review payback, retention and funding capacity.

Common errors to check

Using an undefined unit.
Excluding material variable costs.
Presenting target economics as observed.
Scaling volume without capacity or working-capital effects.

Reconcile unit economics

Bring unit volumes, revenue and attributable costs to a unit-economics review. Separate observed performance from scale assumptions.
