Most Canadian merchant statements are built to be skimmed, not read. Rows of codes, three different fee categories that all sound the same, and a total at the bottom that never quite matches what you remember charging. That's not an accident. The harder a statement is to parse, the less likely you are to notice the markup buried in it.
You don't need an accounting degree to read one. You need to know what the five or six line items actually mean, and where processors hide their margin. Here's how to get through a statement in fifteen minutes instead of giving up after page one.
Why These Statements Are Built This Way
Every card transaction in Canada involves three separate costs, but most processors report them as one blended number. There's interchange, which goes to the cardholder's bank (Visa, Mastercard, or Amex sets this, not your processor). There's the assessment fee, which goes to the card network itself. And there's the processor's markup, which is the only part your provider actually controls.
When a statement lumps all three into one "discount rate" of, say, 2.65%, you have no way to tell how much of that is Visa's cut and how much is your processor's profit. That's the point. Interchange-plus pricing breaks these apart. Flat-rate and tiered pricing models blend them on purpose.
The Summary Page: Start Here, Then Ignore It
The first page of most statements shows total volume, total transaction count, and total fees. This is useful for one thing only: calculating your effective rate (total fees divided by total volume). It tells you nothing about why you paid what you paid. Don't stop here. Processors count on merchants doing exactly that.
Take that effective rate and write it down. For a typical Canadian retail or restaurant business running a mix of debit and credit, a reasonable effective rate sits somewhere between 1.5% and 2.2% all-in. If yours is north of 2.5%, something in the next few sections is worth digging into.
Interchange Fees: The Part Nobody Controls
Interchange is set by Visa and Mastercard, published publicly, and changes maybe once or twice a year. In Canada, standard consumer credit interchange usually runs somewhere between 1.4% and 1.65% depending on the card tier (premium rewards cards cost more to accept than basic cards). Interac debit is much cheaper, typically a flat fee of a few cents per transaction rather than a percentage.
You can't negotiate interchange. No processor can either, no matter what their sales rep implies. If someone promises to "beat Visa's rates," that's a sign they don't understand their own pricing or they're hoping you don't.
What you can check: does your statement show interchange as its own line, broken down by card type? If it just says "credit card fees" as one number, you're looking at a blended rate, and you can't verify whether you're being overcharged on the markup.
Assessment Fees: Small, Fixed, Often Mislabeled
Assessment fees go straight to Visa or Mastercard as their cut for running the network. These are tiny, usually around 0.13% to 0.17%, and they don't move based on your processor or your negotiating skill. Some statements label these clearly. Others fold them into a generic "network fee" line that also includes markup, which makes it look like a pass-through cost when part of it isn't.
The Markup: Where Your Processor Actually Makes Money
This is the number that matters. Strip out interchange and assessments, and whatever's left is pure processor margin. On an interchange-plus statement, this shows up explicitly, something like "interchange + 0.30% + $0.10 per transaction." That 0.30% and ten cents are the only parts of your pricing that are negotiable.
A reasonable markup for a small or mid-size Canadian merchant generally falls between 0.10% and 0.40% over interchange, plus a small per-transaction fee of a few cents to around fifteen cents. If your statement doesn't show a markup line at all because you're on flat-rate pricing, you're paying a blended rate that's almost always higher than interchange-plus once your volume passes roughly $10,000 to $15,000 a month.
Say a bakery processes $20,000 a month in card sales at a flat 2.65%. That's $530 in fees. If the real blended interchange and assessment cost on that volume is closer to 1.6%, roughly $320, the processor is keeping about $210 a month in markup, nearly $2,500 a year, without the bakery ever seeing that number broken out anywhere.
Monthly Fees, PCI Fees, and the Line Items Designed to Be Ignored
Below the transaction fees, most statements list a handful of flat monthly charges:
- Statement or account fee: usually $5 to $15 a month, sometimes disguised as "gateway access" or "account maintenance."
- PCI compliance fee: typically $5 to $10 a month, charged regardless of whether you've actually completed your PCI self-assessment.
- PCI non-compliance fee: a separate, much larger charge, often $20 to $40 a month, that kicks in if you haven't filed that annual questionnaire. Many merchants pay this for years without knowing a ten-minute form would make it go away.
- Equipment rental: $20 to $50 a month per terminal, which over a three-year term can cost more than just buying the hardware outright.
- Batch fee: a small charge, often $0.10 to $0.25, every time you close out your daily transactions. Fine in isolation, but it adds up for a restaurant batching out seven days a week.
None of these are illegal or even unusual. They just need to be checked every few months, because processors do add them quietly, and "quietly" is the whole business model for some of these fees.
Tiered Pricing: The Model Built to Confuse
If your statement has categories like "qualified," "mid-qualified," and "non-qualified" rates, you're on a tiered pricing plan. This model buckets transactions based on card type and how they were processed, and shifts more of them into the expensive "non-qualified" bucket than interchange would actually require. A basic debit tap and a premium rewards card swipe can land in the same bucket under tiered pricing, even though the underlying interchange cost is wildly different.
There's no way to audit this against real interchange rates, because the tiers are defined by the processor, not by Visa or Mastercard. If you see these three words on your statement, that's the single clearest sign you're overpaying relative to what interchange-plus would cost on the same volume.
How to Calculate Your Real Effective Rate
Pull your last three monthly statements and do this:
- Add up total card volume processed across all three months.
- Add up every fee: interchange, assessments, markup, monthly fees, PCI fees, batch fees, equipment rental.
- Divide total fees by total volume. That's your real effective rate, not the headline "2.4%" a sales rep quoted you two years ago.
- Compare it to the 1.5% to 2.2% range mentioned earlier, adjusted for your card mix. A business that sees mostly premium rewards cards will sit higher. One that sees mostly debit will sit lower.
Say a hardware store runs $45,000 a month in card volume and the statement shows $1,350 in total fees across interchange, assessments, markup, and flat charges. That's a 3.0% effective rate, well above what a reasonable card mix should produce. Something in that stack, probably the markup or the monthly fee pile, is worth questioning.
What to Actually Do With This
Once you know your effective rate and can see where it's padded, you have three options: ask your current processor to move you to interchange-plus pricing with a stated markup, shop the statement around for a direct comparison, or renegotiate the specific line items that are inflated (equipment rental and PCI non-compliance fees are usually the easiest wins).
Whatever you do, don't sign anything based on a single quoted rate again. Ask for the breakdown: interchange, assessment, markup, and every flat fee, in writing, before you agree to a switch-over or a renewal.
