Profit margin formula (Canada example)
Extract GST/HST from tax-inclusive price, then subtract product, Canada Post, ads, and fees. Margin % = Net profit ÷ selling price × 100.
🧢 Example: Apparel — Ontario HST
At 12 sales/day you are near CA$152/day or about CA$55,670/year before fixed overhead — enough for a lean full-time operation if ads stay efficient.
Local rules: GST/HST, fees & CAD
Currency: CAD. Toggle GST 5% vs HST 13% for your province. Shopify Canada + Canada Post integrations are common; shipping is often the margin killer versus US peers.
Cross-border US sales need duty, FX, and delivery expectations modeled separately from domestic CAD carts.
How to use the Canada margin calculator
Pick GST or HST, enter CAD costs and price, then review net profit and margin. Free, no sign-up — then stress-test ad CPA with the ROAS calculator.
Frequently Asked Questions
Real questions sellers ask about this calculator and local costs.
What is the difference between GST and HST in Canada?+
GST is the 5% federal goods and services tax. HST combines federal and provincial tax in participating provinces (e.g. Ontario 13%). BC, Alberta, Manitoba, Quebec and others use GST plus separate provincial taxes. This calculator toggles GST 5% vs HST 13%.
When must Canadian sellers register for GST/HST?+
Registration is generally required once worldwide taxable revenues exceed CA$30,000 in a quarter or over four consecutive quarters. Thresholds are lower than many countries — plan early.
What is a good ecommerce margin in Canada?+
Target roughly 25–40% net after fees. Canada Post shipping is often higher than US parcel rates, so bake CA$8–15 domestic shipping into pricing or offer free shipping with higher sticker prices.
How do Shopify fees work in Canada?+
Plans mirror global tiers in CAD terms, and Shopify Payments is available with rates similar to US-style % + fixed (e.g. about 2.9% + CA$0.30 on Basic). Always confirm current Shopify Canada rates.
Do I need PST as well as GST?+
In non-harmonized provinces you may collect PST/QST separately (e.g. BC, Manitoba, Saskatchewan, Quebec). This tool focuses on GST/HST — ask a Canadian accountant for PST.
Can Canadian stores sell to the US?+
Yes via Shopify Markets and multi-currency. Watch US duties, exchange rates, and shipping SLAs. Model USD pricing carefully so CAD margins stay intact.
How should I treat tax-inclusive pricing?+
Canadian consumer prices often include tax at checkout. Use the GST/HST toggle so margin calculation reflects net revenue after extracting tax.
Is the calculator free?+
Yes — free, no sign-up. Estimates only; verify with your accountant for filing.

How we calculate
Canada modes treat listed price as tax-inclusive for GST/HST extraction (5% or 13%), then subtract COGS, shipping, ads, and % + fixed platform fees. Margin = net profit ÷ selling price. Confirm provincial PST obligations separately.
