Ecommerce unit economics
Order contribution margin, with your fee stack.
A Shopify-style order view for testing what remains after discounts, fulfilment, shipping, payment, platform, advertising, and returns assumptions.
Order inputs
Per-order result
Method and limitations
Source / provenance: user-entered order assumptions. The calculator runs locally in your browser using net revenue − per-order costs; percentage fees are applied to net revenue.
This is a contribution view, not net income. Taxes, fixed overhead, inventory shrinkage, chargebacks, and attribution nuance are only included if you add them to an input. “Shopify-style” describes the scenario shape; this is not an official Shopify calculation and contains no current Shopify fee schedule.
