Ecommerce Profit Per Order Calculator
Calculate profit per order after product costs, fulfillment, selling fees, shipping, and advertising.

See what a real ecommerce order earns after variable costs and advertising
Use this calculator when you already have a selling price and want to understand the profit left after the costs attached to one order.
The calculator starts with selling price, subtracts product and fulfillment costs, then calculates percentage selling fees from revenue.
Advertising cost is kept visible so you can compare pre-ad contribution with final profit after acquisition.
This is a per-order model. It does not automatically include fixed monthly overhead unless you allocate part of that overhead into one of the cost inputs.
How the calculation works
The calculation deliberately separates pre-ad profitability from post-ad profitability.
Build non-ad order cost
Product, fulfillment, packaging, shipping, other variable costs, and selling fees are combined.
Calculate pre-ad profit
Non-ad cost is subtracted from selling price.
Subtract advertising cost
Average ad cost per order is deducted to find final profit per order.
Calculate break-even ad limits
Pre-ad profit becomes the maximum ad cost the order can support at zero profit.
Example profit per order
Suppose an order sells for $50 with the following costs:
Total cost per order is $35.25 and profit per order is $14.75, a 29.5% profit margin. Pre-ad profit is $17.75, so break-even ad cost is $17.75 and break-even ROAS is about 2.82.
What each result means
The result panel helps distinguish product economics from advertising economics.
Profit per order
Selling price minus all included costs, including advertising.
Pre-ad profit
Profit left before advertising cost is deducted.
Break-even ad cost
The maximum ad cost one order can absorb before final profit reaches zero.
Break-even ROAS
The revenue-to-ad-spend ratio corresponding to the break-even ad cost.
Profit per order questions
Common questions about what belongs in ecommerce unit economics.
Should I include discounts in selling price?
Yes. Use the actual average amount collected from the customer after discounts if you want the result to reflect promotional orders.
Should taxes be included?
Use a consistent revenue basis. If taxes collected are passed through and are not revenue to the business, they normally should not be treated as selling revenue in this unit-economics model.
What if advertising cost is zero?
Then profit per order equals pre-ad profit and the calculator still shows how much acquisition spend the order could theoretically support.
Does this include overhead?
Only if you explicitly allocate overhead into the entered costs. The calculator is primarily designed for variable per-order economics.
