Basics of WooCommerce Payment Gateway Fees

WooCommerce payment gateway fees are the percentages and fixed cents that processors like Stripe and PayPal deduct from every online order.

WooCommerce itself is free, but the payment gateways you connect are not. Every time a customer pays, the processor deducts a small percentage plus a fixed amount. These fees cover fraud prevention, settlement services, and the card networks' interchange costs.

Published rates in 2026 typically fall between 2.6% and 3.5% plus 30¢ to 49¢ for US merchants. The exact number depends on your provider, your monthly volume, and whether your customers use international cards. Because these costs come straight out of your revenue, comparing them before you launch your store makes a measurable difference.

Stripe Fee Structure for US Online Stores

Stripe charges US stores a flat 2.9% plus 30¢ for online card payments and adds no monthly gateway fee, making it a popular first choice.

Stripe is the default payment gateway inside WooCommerce, and its published US rate has stayed near 2.9% plus 30¢ per successful online charge. There is no setup cost, no monthly fee, and you only pay when a transaction succeeds. This simple structure makes it easy to predict your processing cost per order.

You should watch two extras, though. International cards cost more in currency conversion, and chargebacks cost $15 each. A store with a $50 average order value would pay about $1.75 to process that sale, before any disputed transactions occur.

PayPal Fees and US Merchant Costs

PayPal's standard US rate of about 3.49% plus 49¢ per transaction is higher than Stripe for most small stores, but the brand recognition can improve conversion.

PayPal is still one of the easiest ways to take money online, and many US shoppers trust it. Its standard commercial rate for online payments is roughly 3.49% plus 49¢ per transaction in 2026. That's noticeably more than Stripe for a typical $40 order, where PayPal would deduct about $1.89.

However, PayPal offers strong buyer protection and a large customer base. If you sell digital products or collect international payments, PayPal's currency conversion fee can add even more. Compare your actual order volume and customer location before ruling it out.

Square Fees for WooCommerce Merchants

Square charges US online stores 2.9% plus 30¢ per transaction, matching Stripe's headline rate, but the money settles into your Square balance.

Square began as a card reader company, but its payment gateway works well with WooCommerce. The online rate in the US is 2.9% plus 30¢ per transaction, which ties Stripe on price. There are no monthly fees for the basic plan, and compatibility with the Square ecosystem is a plus for stores that also sell in person.

The main difference is how funds flow. With Square, your payouts land in your Square account balance before you transfer them to a bank. This extra step can affect cash flow, so choose Square if you value unified in-person and online reporting over direct settlement.

Klarna and Buy Now, Pay Later Costs

Klarna's merchant fees are higher than standard processing, often totaling 5–7% per order, but they can boost average order value for US stores.

Klarna is a buy-now-pay-later option that many US customers expect at checkout. Instead of a simple card rate, Klarna bills merchants a fee that commonly lands between 5% and 7% of the order, depending on your volume and contract. WooCommerce integrates with Klarna through an official extension.

Why accept it? Because installment options typically lift order size and conversion. A customer who might hesitate at a $300 total often says yes when it's split into four $75 payments. If your product margins are high enough to absorb a purchase fee near 6%, Klarna can become a profitable gateway rather than just a cost.

Hidden Fees That Raise Your Real Rate

Hidden fees, including chargebacks, currency conversion, and monthly subscriptions, can make your effective WooCommerce processing cost much higher than the headline percentage.

A quoted rate like 2.9% plus 30¢ is only the beginning. Chargeback fees in the US often run between $15 and $25 per dispute. If you sell internationally, a currency conversion charge applies to each foreign card, often 1% or 2%. Some gateways, such as Authorize.Net, charge a monthly fee just for access.

Then there are annual PCI compliance fees and address verification costs. The best way to compare 2026 payment gateways for WooCommerce is to build a simple estimate using your average order value, monthly transactions, and likely dispute rate. That number, not the marketing page, tells you the real cost.

How to Pick the Most Affordable Gateway

Choose a WooCommerce payment gateway by comparing effective rates based on your order size, volume, and international sales, not just the headline percentage.

Start with your average order value. A $30 store and a $300 store experience the same percentage very differently, because the fixed cents portion matters more on small sales. Next, estimate monthly volume; some gateways negotiate lower rates after a few thousand dollars in sales.

Finally, consider where your customers live and what they prefer. US shoppers often feel comfortable with PayPal and cards, while a younger audience may request Klarna. Use a fee calculator from each processor, and check the current published rates for 2026.
