How to use the Unit Economics Calculator.
Choose the unit and accounting boundary before calculating unit economics. Contribution calculations must identify which variable costs are included and which fixed costs remain outside the result.
Make the workflow fit your task.
Define the unit, revenue basis and included variable costs. Calculate contribution and margin with the denominator stated, then list excluded fixed or uncertain costs. Compare like-for-like units before using the result to assess changes.
- What you provide
- Revenue and cost assumptions per customer or unit.

Illustrative input and output · a teaching example, not a live WebAct run
Example input
An order earns USD 50 revenue and incurs USD 18 goods cost, USD 5 fulfillment and USD 2 payment fees.
Completed example
Contribution per order: 50 − 18 − 5 − 2 = USD 25. Contribution margin: 50%. Fixed overhead, returns and any unlisted variable costs are excluded.

Decisions and troubleshooting.
Is contribution per order the same as company profit?
No. Fixed overhead and excluded costs still need to be covered. Keep the calculation's scope explicit.
Why does unit margin look unusually high after a price change?
Returns, discounts, fulfillment or payment costs may be missing or measured on a different basis. Reconcile all included inputs.
