Direct answer

Shopify profit per order equals the net price after discount, minus payment processing, product cost, absorbed shipping and ad cost per order — then reduced by your expected return rate.

Key takeaways

Shopify Payments US default is 2.9% + $0.30 per transaction.
Ad cost per order (CAC) is usually the biggest single cost line.
Returns often destroy the last few points of margin — model them.
Discounts are a real cost — don't ignore promo codes.

Method

Profit = Price × (1 − Discount%) − Payment fee (% + flat) − COGS − Shipping absorbed − Ad cost per order, adjusted for return rate.

How this tool works

The tool subtracts the discount from price, computes payment processing on the net, then subtracts COGS, shipping and ad cost per order. Returns reduce the resulting per-order profit proportionally.

When to use this

Use before launching a promo, changing shipping strategy, or approving a new ad channel.

Step-by-step

Enter selling price and COGS.
Set payment processing (default 2.9% + $0.30 in the US).
Add absorbed shipping and ad cost per order.
Set discount and return rate.
Read profit per order and net margin.

US example

At $55 with 10% off, 2.9% + $0.30 processing, $16 COGS, $6 shipping and $11 CAC, profit per order is about $10.75 before returns; at 6% returns, roughly $10.11 — an 18.4% net margin.

Common mistakes

Skipping the flat $0.30 payment fee on low-ticket items.
Using a discounted price for calculating processing.
Assuming a 0% return rate on apparel or footwear.

Frequently asked questions

How do I calculate Shopify profit?

Take net revenue after discounts, subtract payment processing (typically 2.9% + $0.30 for Shopify Payments in the US), COGS, absorbed shipping, and ad cost per order. Then apply your return rate as a loss on profit.

Does Shopify charge extra transaction fees?

Only if you use a third-party gateway instead of Shopify Payments. If so, add the extra 0.5%–2% into the payment processing input.

Is this Shopify profit calculator accurate for US stores?

It uses editable inputs, so accuracy depends on the numbers you enter. Use your last 30–90 days of actual data for best results.
