How much does card processing cost a small business in Canada? Worked estimates

A Canadian small business's monthly card processing cost is card sales × its effective cost per dollar + fixed monthly fees. The effective cost per dollar depends mostly on the sales mix: how much is Interac debit (usually a flat fee per transaction), how much is standard versus premium credit, and how much is online or keyed. In the illustrative examples below, effective costs range from well under 1% for a debit-heavy store with large tickets to over 3% for an online seller with small tickets on a flat-rate plan. Your own figure comes from your statements and quotes; the monthly cost estimator turns them into a monthly range.

This page is the overview for the estimates and choosing section. All rates and amounts are illustrative, not provider prices.

Online shop$10,000200100% online credit; $50 averageOnline flat 2.9% + $0.30, $25 gateway$375.003.75%

How the less obvious rows are calculated (all illustrative):

  • Café: credit $9,000 at 1.50% average cost = $135; markup 0.25% = $22.50; 300 credit transactions × $0.08 = $24; 300 debit × $0.10 = $30; fixed $20. Total $231.50. The full comparison across pricing models is in flat rate vs interchange-plus.
  • Hardware store: $22,000 credit at 1.85% all-in = $407; 300 debit × $0.08 = $24; fixed $25. Total $456.
  • Clinic: $17,500 credit at an all-in 2.20% = $385; 75 debit × $0.10 = $7.50; fixed $30. Total $422.50.
  • Online shop: $10,000 × 2.9% = $290; 200 × $0.30 = $60; gateway $25. Total $375.

The kiosk shows a common trap: with a $6 ticket, flat debit pricing would be relatively costly too, but a percentage on everything is simple and has no fixed fees. A kiosk with an interchange-plus plan and $30 of fixed fees could end up paying close to the same.

Build your own estimate in four steps

  1. Collect three months of statements (or POS reports if you are new): volume, transactions, and the split by card type and channel.
  2. Calculate your current effective rate: total fees ÷ card sales. The method is in how to calculate your effective rate.
  3. Price each quote on the same month using the card fee calculator: run debit and credit separately if the quote prices them separately, then add fixed fees.
  4. Test a slow and a busy month. Fixed fees and minimums hurt in slow months; percentage fees dominate in busy ones.

Using the estimator for a first budget

If you have no statements yet, the monthly cost estimator gives a range. Its first option, an in-person mix of debit and credit at an illustrative $14 to $22 per $1,000 processed, gives for $15,000 a month and $40 of fixed fees: 15 × $14 + $40 = $250 low and 15 × $22 + $40 = $370 high. Choose a different mix to see how much debit or online sales move the range.

FAQ

Why is my effective rate higher than my quoted rate?

Fixed fees, per-transaction fees, premium and keyed cards and debit priced as a percentage all push the effective rate above the headline. The statement shows the real total.

Is it worth negotiating at low volume?

At low volume, fixed fees matter more than a few basis points. Ask for fixed fees to be removed or reduced, or consider a flat plan without fixed fees.

What volume is "high" for processors?

It varies. Ask each processor at what volume it offers interchange-plus or subscription pricing, and compare at your actual volume.
