01 / Calculation assumptions
Costs for one item
0–99.99% · Combined commission, advertising and payment rates.

0–1,000,000 USD · Up to 2 decimal places.

Price options
0–100% · The discount amount is rounded to the nearest cent.
Calculation assumptions

Replace the example rate with your own. This tool does not use eBay's official fee table. The combined percentage applies only to the product sale price and is rounded once to the nearest cent. A fixed fee is added to every sale. Buyer-paid shipping and sales tax are not included in this model; add tax you pay, packaging and other expenses to your costs.

ROI = profit / total product cost. Margin = profit / sale price. A zero denominator cannot be calculated (—).

02 / Same costs, three options

Positive profit does not confirm the product match, stock availability or likelihood of a sale.
