How to Calculate Profit Margin for Your Shopify Store (2024)

Updated October 2026 · 4 min read

Knowing your profit margin is the single most important number for any ecommerce business. It tells you how much of every dollar of revenue actually stays with you after costs. A Shopify store with 5% margins is very different from one with 40% margins, even if revenue looks the same.

Gross Profit Margin vs Net Profit Margin

Gross profit margin only accounts for the cost of goods sold (COGS) — what you paid for the product, shipping to you, and packaging.

Net profit margin deducts all costs — COGS, Shopify fees, advertising, apps, returns, and your time.

What Is a Good Profit Margin for Shopify?

• Below 20%: Thin — you are very exposed to ad cost increases
• 20–40%: Healthy for most product categories
• 40–60%+: Strong — room for marketing spend and growth
• 60%+: Excellent — common in digital products, supplements, beauty

Dropshipping stores often run 15–30% gross margins. Private-label brands typically aim for 50–70% gross margins to leave room for Meta and Google ad spend.

Markup vs Margin: The Common Mistake

These are not the same thing. If you buy a product for $10 and sell for $25:

• Markup = ($25 − $10) ÷ $10 = 150% markup
• Margin = ($25 − $10) ÷ $25 = 60% margin

Many store owners confuse markup with margin and end up underpricing their products. Always calculate margin (relative to revenue), not just markup.

Hidden Costs That Kill Ecommerce Margins

• Shopify transaction fees (0.5–2% depending on plan)
• Payment processing (Stripe / Shopify Payments: ~2.9% + $0.30)
• Return rate (industry average: 15–30%)
• Customer acquisition cost (CAC from ads)
• App subscriptions, themes, staff
