The sale is the easy part to see. A customer pays 100 euros, your dashboard shows a sale, everyone is happy. Then the payout lands at 89 dollars and change. Somewhere between the checkout and your bank account, eleven percent evaporated, and no single line item explains it.
This dispatch is about that evaporation. Not subscription plans, not gateway selection, but the quiet mechanics after checkout: currency conversion, cross-border card fees, and payout processing. The stuff that never shows up in your ad dashboards and still eats two to five percent of every international order.
The Currency Conversion Tax
Selling in multiple currencies is good for conversion rates, and it is also a toll booth. When a customer pays in euros and your payout currency is dollars, Shopify Payments converts at the market rate plus a conversion fee, roughly 1.5 to 2 percent depending on your plan and region.
The fee looks small until you run it against a month. Thirty thousand dollars of foreign-currency orders loses 450 to 600 dollars to conversion alone. That is a salary line, not a rounding error.
- Price in local currency by design: set rounded prices per market instead of letting raw conversion produce ugly numbers like 43.71 euros. Shopify Markets handles fixed regional pricing.
- Convert once: if suppliers and ads are paid in dollars, settle in dollars. Every extra hop between currencies is another spread you pay.
- Watch refund conversions: refunds convert back at the new rate, not the original one. On a volatile currency pair you can lose twice on the same order.
Cross-Border Card Fees
Even with zero currency conversion, an international card costs more to process. Most processors add around 1 percent when the customer's card was issued in another country, on top of the base rate. A domestic order at 2.9 percent becomes 3.9 percent across a border.
This is where gateway dispersion bites merchants who sell globally from one entity. Your US orders cost 2.9 percent, your UK orders cost 3.9 percent plus conversion, and your blended rate lands quietly near 4.5. Our payment gateway guide covers choosing processors; the point here is that the blended rate, not the advertised one, is what your margin actually pays.
If a single foreign market grows past 20 to 30 percent of revenue, look at local acquiring through a regional entity or a processor that offers it there. Local acquiring turns cross-border fees into domestic ones. It is paperwork, and it pays.
Payout Mechanics: The Slow Leak
Money that has not arrived is money you cannot spend on ads or stock. Payout timing is a cash-flow cost even when it is free on paper.
- Payout schedules: Shopify Payments settles on a rolling schedule of a few business days depending on your country, and weekends plus bank holidays stretch it. Plan ad spend around the real calendar, not the sale date.
- International payout fees: sellers outside core markets sometimes face wire fees or forced conversion on payouts. Check your payout currency settings before your first big week, not after.
- PayPal withdrawal costs: PayPal applies its own conversion spread when you withdraw in another currency, usually worse than Shopify's. A PayPal-heavy international store can pay the toll twice on the same order: once on the sale, once on the withdrawal.
- Reserves and holds: new stores and high dispute rates trigger rolling reserves. Ten percent of revenue frozen for 90 days is a financing cost nobody budgets for. Keep disputes low; our chargeback playbook exists for exactly this.
The Margin Math You Should Actually Run
Add it up honestly: base processing around 2.9 percent, plus 1 percent cross-border, plus 1.5 to 2 percent conversion, plus the payout spread. An international order can carry 5 to 6 percent in payment costs before product cost, shipping, or ads enter the picture.
Price with the blended rate, not the headline rate. If your margin model only works at 2.9 percent, your international orders are subsidized by domestic ones and you will not see it until the quarter closes. Higher price points absorb this stack far more easily, which is one more reason the math favors them; the numbers are in our high-ticket analysis.
Pull last month's payouts and compare the sale total to the deposit total. The gap is your real payment cost. Name it, price for it, and it stops being a surprise.
Frequently Asked Questions
How much does Shopify charge for currency conversion?
Around 1.5 to 2 percent when a customer pays in a currency different from your payout currency, varying by plan and region. The conversion happens at payout, at the market rate plus that fee.
What is a cross-border fee and when does it apply?
An extra charge of roughly 1 percent, applied when the customer's card was issued in a different country from your processing entity. It applies even without currency conversion, so a dollar card paying a dollar price can still cost more if the card is foreign-issued.
How do I calculate my real payment cost?
Divide total payouts received by total sales for a period, all currencies included. The gap between that percentage and your advertised processing rate is the hidden stack: conversion, cross-border, and payout spreads combined.
