Gross margin and net margin are not the same decision

Gross margin is price minus product cost, as a share of price. It answers whether the product is worth selling at all. Net margin, in this calculator, is what remains after the costs that occur because the order happened: shipping and packaging, payment processing, and the advertising it took to win the order.

Stores usually price off gross margin and then discover the difference at the bank. A $48 item costing $16 has a healthy 67% gross margin. Add $6.10 of shipping and packaging, roughly $1.70 of processing, and $9 of ad spend, and net profit is $15.21 — a 31.7% net margin. Both figures are true and they support opposite decisions about whether to discount.

The four costs the calculator subtracts

  1. Product cost. Landed cost, meaning the unit price plus inbound freight, duty and any per-unit fulfillment handling. The supplier invoice on its own is usually 10 to 25 percent low.
  2. Shipping and packaging. What you pay, not what the customer pays. If you charge for shipping, subtract that revenue from this figure and enter the net cost.
  3. Payment processing. Your rate plus the fixed per-transaction fee. Shopify does not publish a public rate table — its Help Center page on card rates points you at your own admin instead — so read yours from Settings, then Payments, rather than assuming an industry number.
  4. Ad spend per order. Total spend in a period divided by orders attributed to it. Entering zero here produces a contribution margin, which is the right figure for an organic order and the wrong one for a paid channel.

What the break-even price tells you

The break-even output is the price at which this order earns exactly nothing after those four costs. It is the floor beneath which a discount code, a bundle, or a marketplace price match starts costing you money to fulfill.

It also moves in a way that catches people out. Because processing is a percentage, dropping the price does not drop costs proportionally — the fixed per-transaction fee and the ad spend stay where they are. A 20% discount removes considerably more than 20% of the profit, and on a thin-margin item it can remove all of it.

What this Shopify profit margin calculator excludes, on purpose

  • Your Shopify subscription and apps. Fixed monthly costs are covered by total contribution across all orders, not charged to one. The Shopify fee calculator handles that side.
  • Returns and chargebacks. A per-order average understates the cost of a product with a high return rate.
  • Your own time. For a one-person store this is the largest unpriced input in the model.
  • Taxes. Sales tax collected is not revenue, and income tax applies after this line.

Frequently asked questions

What is a good profit margin for a Shopify store?
There is no single figure, because it depends on what the product costs to acquire and to deliver. The more useful test is whether net margin, after ad spend, covers your fixed monthly costs at your current order volume. A 30% net margin on 40 orders a month and on 400 orders a month describe two very different businesses.

How do I calculate net profit margin?
Subtract product cost, shipping and packaging you pay, payment processing, and ad spend from the selling price, then divide the result by the selling price. The calculator above shows the intermediate figures so you can see which cost is driving the outcome.

What is the difference between margin and markup?
Margin is profit as a share of the selling price; markup is profit as a share of the cost. A $16 item sold at $48 carries a 67% gross margin and a 200% markup. Pricing from a markup target and reporting it as margin is a common way to overstate profitability.

Should ad spend be in the margin calculation?
For a paid acquisition channel, leaving it out produces a margin that no order actually earns. Including it turns the output into the figure that decides whether the channel is worth running. For organic and repeat orders, set it to zero and read the result as contribution margin.

Are my numbers saved anywhere?
No. The calculator runs entirely in your browser. Your inputs stay on your device and are remembered locally only so the figures are still there next visit.
