Ecommerce Profit Calculator
Calculate Ecommerce Profit metrics for ecommerce, SaaS, marketing, and operations.
This ecommerce profit calculator finds true net profit per sale (or across a period) by subtracting product cost, shipping, payment processing fees, platform fees, and advertising cost from revenue - going beyond simple gross margin.
Enter your revenue and each cost category, and the calculator returns your net profit and margin.
Worked Calculation Examples
| Scenario | Result | Calculation Step |
|---|---|---|
| $100 sale: $40 COGS, $8 shipping, $3 payment fees, $5 platform fees, $10 ad spend | Net profit $34 (34% margin) | Net = 100 − (40+8+3+5+10) = 100 − 66 = $34. Margin = 34 ÷ 100 = 34%. |
| $50 sale: $25 COGS, $5 shipping, $1.50 payment fees, $2.50 platform fees, $8 ad spend | Net profit $8 (16% margin) | Net = 50 − (25+5+1.5+2.5+8) = 50 − 42 = $8. Margin = 8 ÷ 50 = 16% - noticeably thinner than the first example due to heavier ad spend relative to sale price. |
Why Gross Margin Overstates Real Profit
Gross margin (revenue minus product cost) ignores real costs like payment processing fees (commonly 2-3%), platform fees, shipping costs not passed to the customer, packaging, and advertising spend - a product with a healthy-looking gross margin can still be unprofitable once all these costs are included.
Building a Complete Cost Picture
A full ecommerce profit calculation subtracts every cost tied to making a sale: cost of goods, shipping and fulfillment, payment processing fees, platform or marketplace fees, and customer acquisition (ad spend) cost - only what remains after all of these is true net profit.

Frequently Asked Questions
How do you calculate true ecommerce profit?
Subtract product cost, shipping, payment processing fees, platform fees, and advertising spend from total revenue - what remains is net profit, a more complete picture than gross margin alone.
Why is gross margin not the same as actual profit?
Gross margin only subtracts product cost from revenue, leaving out real expenses like payment fees, platform fees, shipping, and advertising - all of which reduce actual take-home profit.
What percentage do payment processors typically charge?
Most payment processors charge around 2.5-3% plus a small flat fee per transaction, which should be factored into any accurate ecommerce profit calculation.

What does the Ecommerce Profit Calculator calculate?
Calculate Ecommerce Profit metrics for ecommerce, SaaS, marketing, and operations. It is designed for fast browser-based calculations without sign-up, downloads, or manual spreadsheet setup.
What formula does this ecommerce profit use?
The formula is: Net Profit = Revenue − (COGS + Shipping + Payment Fees + Platform Fees + Ad Spend). This full-cost accounting approach reflects standard managerial accounting practice adapted for ecommerce, distinguishing gross margin (revenue minus cost of goods only) from true net profit - a distinction that became increasingly important as online sellers layered in more distinct cost categories (payment processing, marketplace fees, paid advertising) that a simple gross margin calculation from traditional retail accounting never had to account for.
