How to use the calculator
- Pick your Shopify plan. Higher plans pay lower card rates, so the plan is the biggest single input.
- Enter the order total the customer pays, including shipping and tax if they are charged at checkout.
- Toggle international card if the buyer's card was issued outside your store's country. Cross-border cards carry a higher rate.
- Toggle third-party gateway if you process payments through PayPal, Stripe, Authorize.net or another provider instead of Shopify Payments.
- Read the results: total fees, net payout and effective fee percentage.
The fee components explained
Card processing fee
With Shopify Payments, each card transaction is charged a percentage of the order plus a small fixed amount per transaction. The percentage drops as you move up plans. Because the fixed portion does not shrink with order size, small orders always have a higher effective fee rate than large ones. Try a low order value and then a high one in the calculator above and watch the effective percentage move.
International card surcharge
When a customer pays with a card issued in another country, Shopify adds an extra percentage on top of the standard rate. If a meaningful share of your sales comes from abroad, run your typical order value with the toggle on and off to see the real gap.
Third-party transaction fee
If you use an outside gateway, Shopify charges its own transaction fee on top of whatever that gateway charges. This is the fee most store owners overlook. The calculator shows the Shopify portion; remember that your gateway's own processing fee is still due on top (you can estimate it with our Stripe fee calculator or PayPal fee calculator).
Effective fee percentage
This is total fees divided by the order total. It is the number to compare across plans, gateways and order sizes because it folds the fixed and percentage parts into one figure.
Worked examples
- Plan comparison. Enter your average order value, then switch between plans. Multiply the difference in fees by your monthly order count. If that saving is larger than the difference in subscription price, upgrading pays for itself.
- Gateway check. Enter the same order with the third-party toggle on. The added Shopify transaction fee plus your gateway's fees is the true cost of keeping that gateway.
- Small-order reality. Enter your cheapest product's price. If the effective fee rate is high, consider a minimum order for free shipping or bundling low-priced items.
Common mistakes
- Ignoring the fixed per-transaction fee. It is negligible on large orders and painful on small ones.
- Forgetting the gateway double charge. Using an outside gateway means paying two parties.
- Leaving fees out of ad math. Payment fees reduce the margin your ads have to work with. Feed your net payout, not the order total, into the break-even ROAS calculator so your Google Ads targets reflect what you actually keep.
- Treating refunds as free. On many payment setups, processing fees on refunded orders are not returned. Check your current terms.
Tips to reduce Shopify fees
- Use Shopify Payments where it is available to avoid the extra third-party transaction fee.
- Re-check your plan once a quarter. As volume grows, a higher plan's lower card rate can outweigh its higher subscription.
- Raise average order value with bundles, volume pricing or free-shipping thresholds so the fixed fee is spread over more revenue.
- Track international sales separately so you know how much cross-border surcharges really cost you.
- Keep chargebacks low with clear product descriptions, fast shipping and responsive support. Dispute fees add up quickly.
