What Is Interchange Plus Pricing and Why It Matters

Introduction

If you accept credit cards at your Canadian business, you've probably noticed that your monthly processing statement is confusing at best and misleading at worst. Between "effective rates," bundled fees, and vague line items, it can feel almost impossible to know whether you're getting a fair deal. This is exactly why understanding what is interchange plus pricing and why it matters has become one of the most important financial literacy issues for small business owners across Canada.

Interchange plus pricing is widely considered the most transparent and often the most cost-effective pricing model available for accepting debit and credit cards. Unlike flat-rate or tiered pricing structures that obscure the true cost of a transaction, interchange plus pricing breaks everything down so you can see exactly what you're paying and to whom. For business owners in Toronto, Vancouver, Calgary, Montreal, Ottawa, and everywhere in between, understanding this pricing model can mean the difference between thousands of dollars in savings or unnecessary overpayment every year.

In this guide, we'll walk through exactly how interchange plus pricing works, how it compares to other models, and why it should matter to every Canadian business owner who accepts card payments.

What Is Interchange Plus Pricing?

Interchange plus pricing is a payment processing model made up of two separate components:

  1. Interchange fee - This is the fee set by the card networks (Visa, Mastercard, etc.) and paid to the cardholder's issuing bank. It varies based on the type of card used (rewards cards, corporate cards, debit cards), the transaction method (in-person vs. online), and the merchant category. Interchange rates are non-negotiable and identical no matter which processor you use.
  2. The "plus" markup - This is the fee charged by your payment processor for their services. This markup is typically expressed as a small percentage plus a flat per-transaction fee (for example, interchange + 0.30% + $0.10).

Because interchange fees are published and standardized by the card networks, the only variable that actually changes between processors is the markup. This means that with interchange plus pricing, you can directly compare processors based on one simple number, rather than trying to decode a bundled "effective rate" that hides the markup inside it.

This is fundamentally different from flat-rate pricing (where you pay one blended rate no matter the card type) or tiered pricing (where transactions are grouped into vague buckets like "qualified," "mid-qualified," and "non-qualified," often at inflated rates). Both of those models tend to overcharge on the transactions that actually cost the processor less to handle, padding their margins at your expense.

How Interchange Plus Pricing Works in Practice

Let's say a customer pays with a mid-tier rewards credit card, and the interchange rate for that card is 1.65%. With interchange plus pricing, your statement would show:

  • Interchange fee: 1.65% (paid to the issuing bank, non-negotiable)
  • Processor markup: 0.30% + $0.10 (paid to your processor)
  • Total cost: 1.95% + $0.10 on that transaction

Compare that to a flat-rate provider charging 2.9% + $0.30 on every transaction regardless of card type. On lower-cost debit and standard credit transactions, you could be paying significantly more than necessary under a flat-rate model - the processor pockets the difference between the actual interchange cost and what they charge you.

Because Canadian consumers frequently use premium rewards cards (which carry higher interchange rates than basic cards), the blended averages processors use for flat-rate pricing often work against merchants who see a lot of basic debit or standard card transactions, such as grocery stores, salons, and quick-service restaurants.

Why Interchange Plus Pricing Matters for Canadian Businesses

Understanding what is interchange plus pricing and why it matters isn't just an academic exercise - it has real financial consequences for your business every single month.

1. Transparency You Can Actually Verify

With interchange plus pricing, you can look at your statement, identify the interchange rate for a given transaction (published publicly by Visa and Mastercard Canada), and confirm exactly what markup your processor is charging. Try doing that with a tiered pricing statement - most business owners can't, and that's by design.

2. Lower Costs Over Time

Because you're only paying a small, transparent markup on top of the actual card network cost, interchange plus pricing is very often cheaper overall than flat-rate or tiered pricing, especially for businesses with:

  • Higher transaction volumes
  • A mix of debit and credit transactions
  • Larger average transaction sizes

3. Easier Processor Comparisons

When every processor quotes the same interchange rate (because it's fixed by Visa and Mastercard), the only thing left to compare is the markup. This makes it far easier to compare processors apples-to-apples, rather than trying to interpret marketing language about "our best rate ever."

4. Better Budgeting and Forecasting

Since interchange plus pricing shows the real cost breakdown, you can more accurately forecast processing costs as your sales grow or as your customer payment mix shifts (more online sales, more premium card usage, etc.).

Interchange Plus vs. Other Pricing Models

Flat-Rate Pricing

Flat-rate pricing (popularized by providers like Square and Stripe) charges one blended rate for every transaction. It's simple and predictable, which appeals to very small or new businesses, but it typically costs more per transaction once your volume grows. If you're currently on a flat-rate plan and want to see how it stacks up, our Stripe comparison breaks down the real difference.

Tiered Pricing

Tiered pricing is the least transparent model and, unfortunately, still common among Canadian bank-bundled merchant accounts. Transactions get sorted into "qualified," "mid-qualified," and "non-qualified" buckets - and processors have significant discretion over which transactions land where. This model is common with bank-bundled offerings, which is worth keeping in mind if you're evaluating a TD comparison or a Desjardins comparison for your Quebec-based business.

Interchange Plus Pricing

As discussed, this model separates the fixed interchange cost from the processor's markup, giving you full visibility and typically the lowest overall cost for established or growing businesses.

How to Know If You're Overpaying

Many Canadian business owners have never actually reviewed their processing statement line by line. Here's how to check:

  1. Pull your last three monthly statements. Look for a breakdown of interchange fees separately from processor fees. If you can't find one, you're likely on a tiered or flat-rate plan.
  2. Calculate your effective rate. Divide total fees paid by total card volume processed. If it's above 2%, especially for a business with mostly in-person, debit-heavy transactions, you may be overpaying.
  3. Compare against interchange plus benchmarks. A well-negotiated interchange plus plan often lands in the interchange rate plus 0.10%-0.40%, plus a small per-transaction fee.
  4. Use a savings calculator. Use our savings calculator to estimate exactly how much you could save by switching to a transparent interchange plus plan based on your actual monthly volume.

Industry-Specific Considerations

Different industries experience different cost pressures depending on average transaction size, card mix, and transaction volume:

  • Restaurants often deal with high transaction volume and tipping adjustments - our restaurant solutions are built around these realities.
  • Retail stores benefit from interchange plus pricing especially during high-volume seasons - see our retail solutions.
  • E-commerce businesses face different interchange categories for card-not-present transactions, making transparent pricing even more critical - check out our e-commerce solutions.
  • Healthcare providers, salons and spas, and construction businesses all have unique payment patterns that affect which pricing model saves the most - explore our healthcare solutions, salon & spa solutions, and construction solutions to see tailored recommendations.
  • Hospitality businesses, including hotels and short-term rentals, deal with larger average transactions and pre-authorizations, both of which interact differently with interchange categories - our hospitality solutions page covers this in more detail.

Regardless of your industry, if you're evaluating point-of-sale hardware alongside your payment processing, it's worth reviewing a Clover comparison or Lightspeed comparison to make sure your hardware and processing pricing work together efficiently.

Regional Considerations for Canadian Merchants

Payment processing costs and competitive landscapes can vary depending on where your business operates. Business owners in major hubs like Toronto, Vancouver, Calgary, Montreal, and Ottawa often have more processor options to choose from, which increases the importance of understanding pricing transparency before signing a contract. No matter where you're located in Canada, interchange rates themselves don't change by province - but the markups charged by competing processors absolutely do, so local competition can work in your favour if you know what to look for.

Making the Switch to Interchange Plus Pricing

If you've determined that your business is likely overpaying under a flat-rate or tiered plan, switching to interchange plus pricing is usually straightforward:

  • Review your current contract for early termination fees or equipment lock-in clauses
  • Request a full statement analysis from a prospective processor
  • Confirm the markup percentage and per-transaction fee in writing
  • Ask about PCI compliance fees, statement fees, and other add-ons that might offset your savings

A reputable processor will walk you through all of this without pressure. Contact our team if you'd like a no-obligation review of your current statement - we'll show you exactly where your money is going and whether interchange plus pricing makes sense for your business.

Conclusion

Understanding what is interchange plus pricing and why it matters puts you in control of one of the largest recurring costs in your business. Rather than accepting a mysterious "effective rate" on blind faith, interchange plus pricing lets you see exactly what card networks charge and exactly what your processor charges on top of it. For Canadian business owners looking to reduce costs, improve forecasting, and finally understand their merchant statement, this pricing model is almost always worth pursuing.

Frequently Asked Questions

What is interchange plus pricing and why does it matter for small businesses? Interchange plus pricing separates the non-negotiable interchange fee (set by Visa and Mastercard) from your processor's markup, giving you full visibility into your true processing costs. It matters because it typically results in lower costs and makes it much easier to compare processors fairly.
Is interchange plus pricing always cheaper than flat-rate pricing? Not always, but for most established businesses with regular volume and a mix of debit and credit transactions, interchange plus pricing tends to be less expensive over time. Very small or brand-new businesses with low, unpredictable volume sometimes prefer the simplicity of flat-rate pricing despite the higher average cost.
How do I find the markup in an interchange plus pricing plan? Your processor should clearly disclose the markup as a percentage plus a flat fee (for example, 0.30% + $0.10) on top of the published interchange rate. If a processor can't or won't clearly state this markup, that's a red flag worth investigating further.
Do interchange rates differ across Canadian provinces? No, interchange rates are set nationally by Visa and Mastercard and don't vary by province. However, the markup charged by processors can vary significantly based on local competition and negotiation, which is why it's worth comparing options in your city.
