Shopify Profit Calculator

Method and assumptions

Use a period total rather than a single order to include monthly app costs and actual advertising spend. Enter the processing terms from your plan and payment provider.

Worked scenario

Build an average order using product revenue, discounts, product cost, pick-and-pack, payment processing, app or platform transaction charges, shipping income and actual shipping expense. Compare Shopify Payments with an external gateway using the same order profile so the gateway decision reflects both processing and platform charges.

How to interpret the result

This calculator is an order contribution model, not a complete store income statement. Monthly subscription, apps, theme work, staff and chargebacks should be added as period overhead or allocated with a documented rule. Shipping income should remain visible because free-shipping promotions change both conversion and order contribution.
