Shopify's cost stack has several layers: the monthly plan, apps, credit card rates that differ by plan, and an extra fee if you don't use Shopify Payments. This calculator nets your revenue against all of them plus product and marketing costs.
Used for the fixed $0.30 per-transaction fee.
US online credit card rates; check your region.
Extra fee applies only if you don't use Shopify Payments.
Net profit
$4,681.00
Card fees and the per-order $0.30 hit small order values hardest. If your average order value is low, the fixed fee becomes a meaningful percentage.
Profit = Revenue − COGS − Plan − Apps − Ads − (Revenue × Card Rate + Orders × $0.30) − Gateway Fee
Yes. The rates here reflect common US online card rates; Shopify publishes different rates per country and for in-person sales.
If the business should eventually pay you, include it in costs. Otherwise profit is overstated and decisions built on it will be too optimistic.
