Processors quote you interchange-plus, flat, tiered — anything to avoid the one number that matters. Your effective rate is simply total processing costs divided by total card volume, and it cuts through every pricing model. If your statement shows $1,400 in total fees on $50,000 of volume, your effective rate is 2.8%. The question is whether 2.8% is good. That depends entirely on what you sell.
Your 60-second effective-rate calculation
- Take your last full statement (one month). Find total card volume and total fees charged — every line: interchange, assessments, markup, statement fee, PCI fee, the lot.
- Divide fees by volume. $1,400 ÷ $50,000 = 0.028 = 2.8% effective.
- Match it to your sector below. The same 2.8% is fine for a quick-service restaurant and overpriced for an in-person retailer.
The benchmarks: what's normal by sector
Why the range differs: interchange itself varies by card type (a premium rewards card costs the network ~2.4%; a basic debit card far less), and the floor under your rate is set by the underlying interchange and assessment costs. Published Canadian benchmarks (industry guides, current to 2025):
| Sector | Typical effective rate | Above this = overpaying |
|---|---|---|
| Fine dining | 1.8% – 2.4% | >2.5% |
| Casual dining | 2.0% – 2.6% | >2.7% |
| Quick-service / fast food | 2.2% – 2.8% | >3.0% |
| Bars and nightclubs | 2.3% – 3.0% | >3.0% |
| In-person retail | 1.60% – 2.00% | above range |
| Professional services | 1.60% – 2.00% | above range |
The pattern: sectors with lots of premium or card-not-present transactions (bars, online sellers) sit higher; sectors with in-person debit and basic credit (retail, fine dining) sit lower. Published starting rates for online processing run 2.9% + $0.30 (Stripe) to 3.3% + $0.30 (Square) before any negotiation. Average interchange for eligible Canadian small businesses runs around 0.95% of volume, so an effective rate of 1.60–2.00% for in-person retail means your processor's markup plus assessments adds roughly half a point to a point on top.
The Interac wildcard: Canada's cheapest transaction
A Canada-specific lever most benchmarks bury: Interac debit costs far less than credit — published Interac Flash tiers are flat cents per transaction ($0.020–$0.055 depending on merchant type and ticket, per TD's April 2025 interchange schedule), not a percentage at all. A retailer whose customers tap debit for half their sales has a structurally lower effective rate than an identical store that's all credit. If your effective rate looks high, check your debit share before blaming the processor.
What a bad rate costs: the $50,000 example
Worked example: an in-person retailer processes $50,000/month. At a 2.5% effective rate, fees run $1,250/month — acceptable for the sector. At 3.5%, fees run $1,750/month — clearly overpaying, with no justification from card mix alone. The gap: $500/month, or $6,000/year in recoverable cost. That single percentage point is the entire negotiation.
If you're above your benchmark: what to do
- Check the card mix first. Heavy premium-card or keyed-in volume pushes any model up. Your statement should show the interchange categories — ask your processor if it doesn't.
- Compare quotes in effective-rate terms. Any competing quote can be converted: (their markup + expected interchange + assessments) ÷ your volume. Refuse quotes that can't be expressed this way.
- Negotiate the markup, not the interchange. Interchange is set by the networks; the processor's margin is the only movable part. A 0.5% markup cut on $50k volume is $250/month.

FAQ
What is a good effective rate for a Canadian restaurant?
Roughly 2.0–2.6% for casual dining, 1.8–2.4% for fine dining, 2.2–2.8% for quick-service. Anything above 3% in any restaurant segment is a red flag worth investigating.
Why is my effective rate higher than the quoted rate?
The quoted rate is usually just the processor's markup or one tier of a tiered plan. Your effective rate includes interchange, network assessments, monthly fees and PCI charges — everything. That's why it's the honest number.
Does Interac really change the math that much?
Yes — Interac debit costs flat cents per transaction ($0.020–$0.055 on Flash tiers) versus credit at roughly 1.4–2%+ in person. Every customer who taps debit instead of credit saves you roughly 1–2% of that sale. Staff prompts ("debit or credit?") are free money.
