How to Read Your Results
Net profit shows the dollar amount left after all entered costs are deducted.
Profit margin shows what share of the sale price you keep as profit.
Return on cost helps compare how hard your money is working across different items.
A positive result does not always mean the listing is strong if the margin is too thin for your business model.
Assumptions & Important Notes
- Fee percentage and ad rate are both applied to sale price.
- Examples use simple rounded values for illustration.
- Taxes, refunds, and exchange rate effects are not included unless treated as other costs.
- Each example represents a single completed order.

Frequently Asked Questions
Why do two items with similar sale prices have different margins?
Margins can differ a lot because item cost, shipping, ad spend, and fee rates may not be the same.
Should I judge listings by profit dollars or profit margin?
Both are useful. Profit dollars show cash earned per sale, while margin helps compare efficiency across listings.
Why is return on cost sometimes much higher than margin?
Return on cost uses total cost as the base, which is usually smaller than sale price, so the percentage can be higher.
Do these examples include buyer-paid shipping?
These examples focus on your selling costs. If buyer-paid shipping changes your revenue model, adjust your inputs accordingly.
