Gross margin only subtracts your product cost. True net profit subtracts every real cost that touches an order. The formula is:
Most sellers calculate gross margin (Price − COGS) and stop there. The gap between gross and net is where margins disappear — and where bad scaling decisions are made.
On Shopify Basic with Shopify Payments, every transaction costs 2.9% + 30¢. Sell $49.99 and you lose $1.75 before touching the product. On a $1,000/day store that's over $6,000/year — just in processing. Third-party gateways add another 0.5–2% on top.
Facebook and Google ads are how most Shopify stores acquire customers. $3–8 in ad cost per order doesn't appear in your COGS but absolutely reduces net profit. Misallocate ad spend across your SKU mix and you'll confidently scale the wrong products.
A 5% return rate sounds small. On a $49.99 product that's a $2.50 average cost per unit sold — you lose the sale, may lose the inventory, and often pay return shipping. Apparel, footwear, and electronics routinely see 10–25% return rates.
"Free shipping" is never free — it's subsidized by your margin. Actual shipping varies by zone, package weight, and carrier. Budget a flat average and you'll think your margin is 5–8 points higher than reality, especially for bulky or heavy products.
Branded boxes, tissue paper, thank-you cards, and packing labor add $1–2 per order. On a $49.99 product that's another 2–4% of margin gone before the customer opens the box. Premium unboxing experiences are worth it — but only if you account for them.
Here's what “50% gross margin” actually looks like once every real cost is applied to a typical Shopify SKU.
That's a 37% net margin— not bad. But most sellers see “50% gross margin” and plan pricing, ad spend, and restock around that number. Now run the same product with a 15% return rate, $6 shipping to heavy zones, and $5 ad spend: net profit drops to $9.99 — a 20% net margin. The difference changes every scaling decision you make.
Storewide average margin hides which products are dragging you down. Your best-selling SKU might have a 42% net margin. Your second-best-seller might be losing money after returns. Without SKU-level Shopify profit data, you cannot make confident decisions about:

To calculate your Shopify profit margin per SKU: start with the net sale price after any discounts, then subtract COGS (product cost), Shopify and payment processing fees (typically 2.9% + 30¢ on Basic), actual shipping cost, packaging, your allocated ad spend per order, and a return allowance based on your return rate. Divide the result by net sale price and multiply by 100 to get your net profit margin percentage. The formula: Net Margin % = (Sale Price − COGS − Platform Fee − Shipping − Ad Spend − Returns) ÷ Sale Price × 100.
Shopify charges a monthly subscription fee plus a per-transaction payment processing fee. On Shopify Basic with Shopify Payments, the processing fee is 2.9% + 30¢ per transaction. On Advanced Shopify it drops to 2.4% + 30¢. If you use a third-party payment gateway, Shopify adds an additional 0.5–2% transaction fee on top of your gateway's own fees. Combined, these charges typically consume 3–5% of every sale.
A healthy Shopify net profit margin after all costs — including ads, shipping, fees, packaging, and returns — is typically 15–30% for DTC brands. Below 10% is thin: small increases in ad spend or return rates can flip a SKU unprofitable. Above 30% gives you room to scale ad spend aggressively. Margin benchmarks vary by category: apparel and electronics tend to run 5–20% while beauty and supplements can reach 25–50%.
Ad spend reduces your Shopify profit by exactly what you spend to acquire each order. If your blended customer acquisition cost (CAC) is $5 on a $50 average order, ads alone consume 10% of revenue — before any other cost. Many sellers calculate gross margin without allocating ad spend to individual SKUs, causing them to overestimate profitability. Tracking ad spend per SKU or per collection is critical for accurate Shopify profit analysis.
