What sellers usually miss
App allocation, plan cost per order, returns, packaging, fulfillment, discounts, and ad cost often matter more than the headline processing rate when a store is small or testing paid traffic.
Gateway check
Shopify Payments orders usually use 0 for third-party transaction fee. If a third-party or alternate gateway applies, model that percentage separately from card processing.
Discount safety
The discount + paid traffic preset shows whether your order can survive a sale, a return reserve, fulfillment, packaging, and customer acquisition cost in the same calculation.
How this calculator works
The calculator models one Shopify order using item price, quantity, discount, shipping paid by the customer, tax collected, payment processing rate, flat fee, third-party transaction fee rate, app or plan cost allocation, product cost, fulfillment, packaging, return reserve, and ad cost per order.
Shopify's official help center says third-party transaction fees can apply when using third-party payment providers and gives the formula as product cost after discounts plus tax and shipping, multiplied by the plan rate. Shopify Payments and several exempt payment methods can avoid that third-party transaction fee, but payment processing fees can still apply.
Next seller workflow
Once the economics work, use SKU to Sales to turn product facts into clearer Shopify product pages, benefit bullets, FAQs, SEO sections, ad hooks, and email ideas.
See the SKU to Sales workflowWhen the estimate can be wrong
Shop Pay, Shopify Payments, PayPal, manual methods, gift cards, and store credit can be treated differently.
Third-party transaction fees can use a base that includes product cost after discounts, tax, and shipping charges.
A small store can underestimate true unit economics if monthly app and plan costs are not spread across orders.
Returns can erase the margin that looked acceptable at checkout, especially after ads and outbound fulfillment.
