The resale profit formula
Estimated profit = sale price − item cost − marketplace fees − promotional fees − seller-paid shipping − other item costs.
Profit margin = profit ÷ sale price. ROI = profit ÷ item cost.
Reseller profit calculator questions
How do I calculate reseller profit?
Start with the expected sale price, subtract marketplace and promotional fees, seller-paid shipping, other item costs, and your cost of goods. The amount left is estimated item profit.
What is reseller profit margin?
Profit margin is estimated profit divided by sale price, expressed as a percentage. It shows how much of the selling price remains after the costs entered into the calculator.
What is ROI for a resale item?
This calculator defines item ROI as estimated profit divided by item cost. It is useful for comparing how efficiently different purchases may use your inventory cash.
Does this calculator know the exact fees for every marketplace?
No. Enter the fee percentage that applies to your marketplace, category, account, and promotion setup. Fees can change and may include components not represented by one percentage.
Use profit math before and after you buy.
Use the sourcing calculator to work backward to a maximum buy price, then use this calculator to test an actual purchase against the expected sale price and costs.
