Why Do Payment Gateways Charge Fees?
Updated 1 September 2026

Payment gateways charge fees because every online payment passes through several paid parties. Each takes a cut: the card networks such as Visa and Mastercard, the banks that issue and settle the money, and the gateway itself. The gateway's own share covers security, fraud checks, and payout. Cards cost a percentage because the networks price each transaction by its value. FPX online banking rides Malaysia's interbank rails instead, so it usually costs a flat fee of about RM1.
Where does the fee actually go?
The fee is split between the parties that move and guarantee your money. The gateway does not pocket it whole.
On a card payment, the largest slice is interchange, paid to the bank that issued your customer's card.
A smaller scheme fee goes to Visa or Mastercard for running the network. Whatever is left is the gateway's own margin, which covers its platform, support, and risk.
This is why no provider can price a card sale near zero. Most of the fee is set above them, by parties they do not control.
On an FPX payment the chain is shorter. There is no card network, just an interbank switching fee and the gateway's margin. That is why the flat cost lands near RM1.
Why do cards cost a percentage but FPX a flat fee?
Cards cost a percentage because the risk and the network cost both scale with the amount. FPX is a fixed bank transfer that costs the same whatever the value.
A RM5,000 card sale carries far more fraud and chargeback exposure than a RM50 one, so the networks price it as a share.
FPX has no such exposure. The buyer logs into their own bank and approves the exact amount. There is nothing to charge back and no card data to protect.
That structural difference decides which method protects your margin at your basket size. Card money is priced by risk, FPX by transaction, and those are simply two cost models.
What are you paying the gateway for?
The gateway's share pays for the work that turns a raw bank connection into a checkout you can trust. That work is real and ongoing.
It is why the fee recurs on every sale rather than being a one-time setup charge, unlike the one-off cost of an e-commerce build.
| What the gateway does | Why it costs money |
|---|---|
| Security and PCI-DSS compliance | Protecting card data to a strict, audited standard |
| Fraud screening | Blocking stolen cards and suspicious transactions |
| Settlement and payout | Reconciling sales and moving money to your bank |
| Chargeback handling | Managing disputes on card payments |
| One integration, many methods | Maintaining FPX, cards, and wallets in a single connection |
A pattern we've noticed with first-time store owners is treating payments as a one-time setup. They are then surprised the fee returns on every order. It recurs because the protection does.
How to keep fees from eating your margin
You control your margin by matching the payment method to your basket size. Chasing the lowest headline rate is the wrong instinct. Because FPX is flat and cards are a percentage, the same fee can be trivial or painful.
Sell a RM1,000 package paid by FPX and the fee is around RM1. The same sale by card, at about 3% plus RM1 on Stripe Malaysia (retrieved August 2026), costs about RM31 (illustrative arithmetic, not a client result). On a RM20 sale that logic flips, and the flat RM1 becomes the pricier option.
You cannot force customers onto the method that suits you. You can budget honestly for the mix instead, which is part of judging whether a store pays for itself. Treat these fees as a fixed line in your running costs, the same way you would the rest of your checkout.
Frequently asked questions
Are payment gateway fees negotiable?
At SME volume, rarely, because the published rates are the rates for most small sellers. At higher volume the door usually opens, and providers advertise enterprise or custom pricing. If your store grows into serious monthly turnover, asking for a custom rate is a normal business conversation, not a cheeky one.
Which costs less, a percentage fee or a flat fee?
It depends on your basket size, and neither wins across the board. A flat fee like FPX is the lower-cost option on larger sales, where a percentage would take a big absolute amount. A percentage is the lower-cost option on small sales, where a flat fee becomes a heavy share of the total. Offer both, and let each sale settle through whichever the customer picks.
Do gateway fees apply to refunds?
Often, yes, and policies differ by provider. Some keep the original transaction fee even after you refund the sale. Check the refund terms before choosing a gateway if returns are common in your category. Then build that cost into your margin from the start.
Why can't I just avoid gateways and take bank transfers?
You can for a small operation, but manual transfers do not scale. The buyer has to leave your checkout, transfer by hand, and send proof, and you confirm each one yourself. A gateway automates that confirmation in seconds, which is much of what its fee buys, especially once orders arrive faster than you can check them.
Do the fees change how I should price my products?
Yes, at least a little, because the fee is a real cost of every sale. On thin-margin or low-priced items, a percentage card fee can quietly erase a chunk of your profit. It belongs in your pricing math, not as an afterthought. This matters most for stores weighing a full store against a simple catalog or against selling on a marketplace.
