Shopify Fee Calculator

Shopify looks simple until the store stack spreads across payments, third-party transaction drag, apps, and shipping labels. Use this calculator to see the net left after the Shopify layer before you even start talking about ads.

Calculate Shopify fees

Enter order revenue, product cost, shipping label cost, payment processing rate, any Shopify transaction fee rate, and the app drag allocated to the order. If you use Shopify Payments, the third-party transaction fee can stay at zero.

Order revenue Gross order revenue before the Shopify stack. Product cost Direct product or COGS for the order. Shipping label cost What the order actually costs to ship. Shopify Payments fee rate % Use your plan's current payment rate. Fixed processing fee Fixed fee charged on each transaction. Third-party transaction fee rate % Set to 0 if you use Shopify Payments. Raise it if you use an external gateway. App cost per order Allocated app drag or checkout tooling cost for the order.

Three Shopify store scenarios.

Formula

What the Shopify model includes

Total Shopify drag = Payments fee + Third-party transaction fee + App cost per order

Shopify says stores using Shopify Payments do not pay third-party transaction fees, while stores using an external payment provider can pay both the processor fee and a Shopify transaction fee. This calculator keeps that part explicit so the checkout stack stops hiding inside the payout.

Where stores underestimate drag

App costs get ignored because they are billed monthly instead of per order.
Label cost gets mentally separated from checkout economics.
Changing provider or plan can alter the take more than expected.

Where to go next

Once the Shopify stack is clear, compare it against Stripe or PayPal directly, then collapse the order into payout margin if you want one retained-profit view.

How FeeDeck reviews this page

This page is meant to make the checkout stack visible, not to hide it behind one blended percentage. The calculator separates processor drag, third-party fees, and app burden so the result can be checked against the real store setup.

FAQ

Shopify fee calculator questions

Should third-party transaction fee stay at zero with Shopify Payments?

Yes. If the order uses Shopify Payments, the third-party transaction fee usually stays at zero. Raise it only when an external gateway adds extra drag.

Do app costs belong in a Shopify fee calculator?

They do if the goal is realistic order math. Allocating app cost per order helps show what the checkout stack actually keeps instead of stopping at processor fees.

Should I include ad spend here?

Not on this page. This calculator is for store-stack drag before acquisition. Move into payout margin or ad-to-net margin if you want traffic cost layered in.
