How much are payment gateway fees?
Many companies offer payment gateways payment processing
Under a flat-rate pricing model, you’ll typically pay a percentage of the total transaction cost plus a fixed amount. For example, with a fee of 2.9% + 30 cents per online transaction, you'd pay $3.20 to process a customer's $100 online order.
Other companies use an interchange-plus pricing structure. This model is more complicated, as prices vary based on so-called interchange fees
Interchange-plus pricing is more transparent because you can see where processors are charging markups. It may also be cheaper for your business depending on your underlying transactions, but you’ll have to do some math to be sure.
What is the cheapest payment gateway?
The cheapest payment gateway for your business will depend on the product’s pricing type (flat rate or interchange-plus) and your business’s monthly sales volume, among other factors. There isn’t a one-size-fits-all option.
Here are some additional tips to help you track down the right solution:
Know what type of service you need
Not all payment gateways work the same way. Some will redirect customers away from your site to the gateway's site for payment, which can negatively affect completion rates. Others have pre-built payment gateways you can embed directly on your website. White-label gateways
It's important to confirm that the gateway will work the way you expect and have a price tag you're comfortable with.
Look for transparency
It's easiest to compare prices when they're published. A company that uses custom pricing or requires you to call for a quote might have a reasonable price, but it takes more time to compare. Aside from monthly and processing fees, look for other fees that could impact your costs.
Avoid those extra fees (most of the time)
There's no getting around paying a per-transaction fee. But most businesses can avoid companies that charge additional fees, like fees for setup or PCI compliance
However, not all fees should be avoided equally. Before you rule out every payment gateway that charges a monthly fee for service, consider the total costs. Companies with monthly fees sometimes offer great per-transaction fees. Depending on your sales information, you might come out ahead, even after paying a monthly fee. The only way to know for sure is to run your numbers. Use this calculator to estimate your costs:
