What payment gateway charges actually are
A payment gateway is the plumbing that carries a card payment from your checkout to your bank. Every time it does that job, it takes a cut. That cut is the "payment gateway charge," and for most small stores it is the third-largest cost after the product itself and advertising.
The charge is not one fee — it is a stack of them. Some hit on every single order, some hit monthly, and a few only show up when something goes wrong, like a dispute. Understanding which is which is the difference between pricing a product that makes money and one that quietly loses it.
The main types of payment gateway charges
Most gateways bundle several charge types. Here are the ones that matter for a small online store.
- Per-transaction fee (percentage). A slice of every sale — the biggest and most predictable charge. The general industry range is about 1.10% to 3.15% of the transaction, per Stripe's fee guide.
- Per-transaction fixed fee. A flat amount added to each order, commonly a few dimes. This is the fee that hurts low-priced items most, because it does not shrink with the basket.
- Monthly or subscription fee. A recurring platform charge, separate from what you pay per sale. Treat this as a fixed running cost, not a per-order cost.
- Chargeback / dispute fee. Charged when a customer disputes a payment. On Shopify Payments this is $15 in the US, and it is refunded to you if you win the dispute, according to A2X's Shopify fees guide.
- Cross-border and currency fees. Extra charges on international cards. Wise notes a currency-conversion fee is likely to be 1% or more, with international payments running around 1.5% higher than a local one.
- Third-party gateway markup. If your platform lets you plug in an outside processor, it may add its own transaction fee on top.
What payment gateway charges cost on Shopify
Because so many small stores run on Shopify, its published rates are a useful benchmark. The processing rate falls as you move up plans, and using an outside gateway triggers an extra fee.
The rates below are the online standard card rates from Shopify's pricing page:
| Plan | Online card rate | Fee if you use a third-party gateway |
|---|---|---|
| Basic | 2.9% + 30¢ | 2.0% |
| Grow | 2.7% + 30¢ | 1.0% |
| Advanced | 2.5% + 30¢ | 0.6% |
Two things jump out. First, the percentage only drops a few tenths of a point between plans — real, but modest. Second, running an external processor instead of the built-in one stacks a second fee on top of whatever that processor already charges, which is why keeping payments native is usually cheaper.
Worked example: what the gateway takes from one order
Numbers are abstract until you run one order through them. Say you sell a t-shirt for $32 on the Basic plan, using the 2.9% + 30¢ rate above.
The percentage: 2.9% × $32 = $0.93. The fixed fee: $0.30. Total gateway charge: $0.93 + $0.30 = $1.23 on that single order. That is about 3.8% of the sale, not 2.9% — the fixed 30¢ inflates the effective rate on anything cheap.
Now scale it. Say you do 300 of those orders in a month. Gateway charges: 300 × $1.23 = $369 for the month. If your product cost is $12 and you spend $10 in ads to win each sale, the gateway charge is the quiet line that turns a "profitable" order into a thin one.
Watch what the fixed fee does to a $12 impulse item instead: 2.9% × $12 = $0.35, plus $0.30 = $0.65, or about 5.4% of the sale. The cheaper your average order, the more the gateway takes as a share. That is the single most useful thing to know about payment gateway charges.
Where these charges belong on your P&L
Here is where most small stores go wrong: they never see gateway charges as a line at all, because they book the net payout Shopify deposits as if it were revenue. That deposit is already sales minus fees minus refunds — so the fees vanish and the margin looks better than it is.
The fix is to record gross sales at the top and payment processing as its own line, as laid out in our ecommerce P&L guide. Whether you park processing inside cost of goods sold or in operating expenses is a judgment call — just be consistent, because inconsistency is exactly what makes a gross margin look mysteriously high one month and unexpectedly low the next.
If the letters themselves trip you up, our note on P&L vs. P and L clears it up — they are the same statement. The point is that a fee you cannot see is a fee you cannot price against.
The refund gotcha most stores miss
Refund an order and you would expect the gateway charge to come back too. It generally does not. The original processing fee usually stays gone, according to standard Shopify fee accounting from A2X.
So a refunded $32 order costs you the roughly $1.23 fee even though you kept none of the sale. On a store with a high return rate, that leakage adds up fast — and it never shows up if you only ever look at net payouts.
How to lower your payment gateway charges
You cannot make these charges disappear, but you can shrink them.
- Raise your average order value. Because the fixed fee is flat, bundling two $16 items into one $32 order cuts the per-item fee burden roughly in half. Order bumps and free-shipping thresholds do real work here.
- Use the native processor. Avoiding a third-party gateway sidesteps the extra platform fee shown in the table above.
- Earn the plan discount. Moving up a plan trims the percentage, per Shopify's rates — worth modeling once your volume is high enough that the lower rate outweighs the higher subscription.
- Fight winnable disputes. Since the $15 US dispute fee is returned when you win, per A2X, contesting fraudulent chargebacks recovers both the sale and the fee.
See gateway charges inside true per-order profit
The reason gateway charges feel invisible is that no single screen usually subtracts them from the same order that also paid for the ad, the product, and the shipping. PodVector connects your Shopify, Meta Ads, Google Ads, Printify, and Printful data and computes true per-order profit — so the $1.23 the gateway took sits right next to the ad spend and the print cost on that exact sale.
Victor, the AI operator inside PodVector, reads that live data and proposes moves, then executes the ones you approve on the Shopify side. He is not a dashboard and he does not touch your ad account — he reads the numbers, tells you where the margin is leaking, and acts with your sign-off. Start free and see your real per-order profit.

FAQs
What is the average payment gateway charge?
For online card payments, the general industry range is roughly 1.10% to 3.15% of the transaction, according to Stripe's fee guide. Many small stores land near 2.9% plus a fixed fee of about 30¢ per order on entry-level plans, per Shopify's pricing. The effective rate on cheap items is higher than the headline percentage because of that flat fee.
Do payment gateway charges come out of every sale?
The per-transaction percentage and fixed fee do — they apply to essentially every card order. Monthly subscription fees are separate and hit once a period, while dispute and cross-border fees only appear in specific situations. That is why booking processing as its own P&L line, as covered in our ecommerce P&L guide, keeps the picture honest.
Are payment gateway charges refunded when I refund an order?
Usually not. The original processing fee generally stays with the processor even after you refund the customer, per A2X's Shopify fee accounting. So refunds cost you the fee on top of the lost sale, which is worth tracking if your return rate is high.
Is it cheaper to use a third-party payment gateway?
Often not, on Shopify. Using an outside processor adds a platform transaction fee — 2.0% on Basic, dropping to 0.6% on Advanced, per Shopify's pricing — on top of whatever that processor charges. Keeping payments native usually avoids that extra layer.
Where should payment gateway charges go on my P&L?
In either cost of goods sold or operating expenses — the key is consistency, because switching month to month distorts your margin trend. Inconsistent placement is a common reason a gross margin looks off without an obvious cause. Pick one home for the fee and keep it there.
