Merchant account pricing can be confusing and maybe a little overwhelming at times.
I’ll show you how it works, tell you what interchange is and show you why knowing this information is important if you’re going to be accepting credit cards at your business
If you’re familiar with merchant accounts or you’ve researched pricing at all, you’ve probably heard the term interchange and interchange pricing.
And that’s because it’s at the core of every pricing model that exists in the merchant services industry… so let’s just make sure that’s understood right up front.
Every rate or fee that is charged for accepting a credit card payment, no matter who the provider is, is driven in some way by interchange.

So let’s just start with a simple definition.
Interchange Introduction and definition
Interchange is a schedule of fees that determine the price and percentage rates (referred to as a “discount rate.” ) for accepting credit card transactions.
There are literally hundreds of different interchange categories, each category holding a different rate AND transaction cost.
Company A follows interchange and Processor B follows interchange too
Interchange is kind of like what the prime rate is for the mortgage or financial industry in the sense that it’s the same for every company and acts like a base cost for processing credit and debit cards.
Generally speaking, every processor complies with same interchange rules.
However, each processing company does have control over how the transaction is processed in terms of the cardholder data that is captured and sent for authorization (as well as the security that surrounds that transaction) and that could affect the rates you pay.
So with that in mind, it does matter what processing company you use.

Here’s my recommended processor
How are rates determined?
A single interchange rate is paid every time a transaction is made whether it’s Visa, Mastercard, or Discover or American Express
Some rates are lower than others because, for example, they are determined to be less of a risk to the card issuing bank and less likely to have chargebacks occur.
Some other of the most notable factors that determine the exact cost of each interchange rate category are:
- The type of business / Merchant SIC code
- How the payment is accepted (face-to-face or via the internet)
- Cost of the sale (average ticket or purchasing card)
- The type of credit card (business corporate card, vs. individual card)
- Processing technology (interchange optimization for IP “high speed” connection)
- Daily settlement
So when a card is presented at the point of sale, it falls into ONE of the interchange categories based on these qualifying factors.
***NOTE: Interchange rates are subject to change and a the card brands publish the rates 2 times per year.
So let’s look at the individual fee and where the interchange fee goes (who it’s paid to) and how it’s split up.
Where does the money go?
Throughout any given transaction, the fee that is collected is split up between 3 parties:
- The card issuing bank, (which is the bank that gave the customer the credit card)
- the processing company (aka the aquirer) and
- the Visa/Mastercard association (in what’s called dues and assessments)

The merchant service provider pays interchange directly to the cardholder’s bank, so when you hear the term, “interchange, pass through” pricing,” this is where it comes from
The merchant account processor simply “passes through” those exact costs to you, just as they paid to the issuing bank.
The rate and fee structure that you pay for your merchant account is based on the variables I outlined before as well as the technology solutions offered to you with your merchant account.
Okay now, here’s the good part.
How does knowing this benefit you?
Well, knowing this information allows you to engage in best credit card acceptance practices to help you achieve lower rates.
In simple terms, there are things you can do that to help qualify a credit card, into a lower interchange rate category
These are things like,
- Using address verification service.
- Entering as much cardholder data as possible such as the 3 digit code on the back of the card, the billing zip code and even the full address of the cardholder. This may only apply to certain types of POS equipment or virtual terminals, but if you can enter it, you should.
- Settling your terminal or sending out your ‘batch” every day
- Always swiping or dipping the card when possible (applicable for card present and retail environments)
- And using the VOID transaction function instead of refunding transaction when possible.
Additionally, there is a way to “Optimize” your rates, IF you are using an interchange plus pricing program AND you are using a processing company that allows for this special optimization and rate reduction.
And by the way is NOT available with aggregator payment service providers like Stripe, Paypal, or Square.
How does it relate to you and your statement?
Regardless of your pricing structure (whether it’s interchange plus or Tier based pricing) you always want to pay attention to the end of the month fee, which can be used to calculate your effective rate, and that is listed on your monthly statement.
So when your merchant account statement comes each month, you’ll see interchange categories listed on it along with the associated interchange category label.
So on this statement, for example, categories like Merit 1 or Merit 3 Debit, or CPS Rewards 1 and so on…
All of those are interchange categories that exist for specific credit cards, that consumers are currently using to pay you with.
Qualifications and Downgrades
So as I mentioned before, a single rate is paid every time a credit card transaction is accepted and
Each transaction needs to “qualify” for all of the requirements ((in other words, they need to meet all the benchmarks) of each interchange category in order to meet that category rate.
So here’s the posted interchange rate table from Visa. and in this schedule of fees, you can see the CPS Rewards 1 category right here..
The chart gives you requirements for the interchange category, Limitations on card types and industries, and then the associated rate for that category
These rates, again, are what show up on your statement, just like in the example we just went through, as “passed through” to you from the merchant account processors.
How to use interchange to your advantage
So, by knowing how interchange works, you’re able to “play the game” as they say, within the rules that are there for you to take advantage of…
So use these card acceptance best practices and these suggestions that I’ve laid out for you, to help ensure that you’re doing everything you can to pay as little as possible.
Now that you have an understanding of the foundation of the pricing for accepting credit cards, the follow up video I’ll cover the 2 main pricing models in the merchant services industry.
