How to calculate your real profit on Shopify
Shopify's reports show gross margin on the item costs you typed in. Real profit needs eight more numbers. Here is the whole method, simply.
Why the Shopify dashboard is not your profit
Shopify's profit reports rely on the cost-per-item field you fill in manually, and they ignore ad spend, shipping costs, payment fees, taxes and operating costs. A store can show a healthy margin there and still lose money every month.
Also, do not confuse margin with markup. A 50% markup is a 33% margin. Mixing these up quietly misprices whole catalogs.
The real formula
Net profit = revenue, minus COGS, minus shipping and packaging, minus payment and transaction fees, minus ad spend, minus apps and tools, minus returns and refunds, minus overhead.
Divide by revenue for net margin. A 60% gross margin routinely ends as a 3 to 10% net margin once everything real is counted. See what a good margin actually is for the benchmarks.
The weekly 4-number habit
You do not need an accountant to stay on top of this. Track four numbers weekly:
- Revenue, the number you already watch.
- COGS, landed cost of what you sold.
- CAC, total acquisition spend divided by new customers.
- Contribution margin, revenue minus COGS minus variable costs minus acquisition. This is the number that decides whether scaling helps or hurts.
Do it once by hand, then automate it
Run one order through the free profit margin calculator to see your per-order truth today. The manual version teaches you the math; the problem is keeping it live as costs, mix and ad spend shift daily.
That continuous version is what Lytix does: real net profit per day and per product, computed from your store data, with one recommended action every morning.

Common questions
Does Shopify show real profit?
No. Its profit reports use manually entered item costs and exclude ad spend, shipping, payment fees and operating costs, so they show an optimistic gross view, not net profit.
What is the difference between gross, net and contribution margin?
Gross is revenue minus product cost. Contribution subtracts variable costs and acquisition per order. Net subtracts everything including overhead. Decisions about ads and scaling should use contribution; health checks use net.
How often should I calculate profit?
Weekly for the four core numbers, monthly for the full P&L. Daily checking of revenue alone is emotion, not information.
