CrosslistyMax buy price calculator: the most you should pay
Enter what the item sells for, the marketplace, your shipping and the profit you want. You get the most you can pay and still hit that profit. Use real sold prices, not asking prices, because asking prices often run higher than what buyers pay.
The shortcut: Listing on several marketplaces gives an item more chances to sell at your price. Crosslisty does the copying.
Add to Chrome, free- Decide your limit before you’re standing in the aisle.
- Use sold prices. Asking prices show what sellers hope for.
- Leave extra margin on items that sell slowly.
Updated October 2026. Crosslisty is a Chrome extension (it also works in Brave and Edge) that copies a listing to the other marketplaces, fills each form for you, and removes sold items from your other listings.
How the number is worked out
Sale price, minus the marketplace’s fees, minus your shipping and supplies, minus the profit you want. What is left is your limit. If you would pay more, you earn less than your goal. If it comes out at zero, the item doesn’t meet your goal at any price.
Rules sellers use
- Some sellers want a minimum dollar profit per item, so that a cheap flip still pays for the time.
- Some use a multiple of cost, such as paying no more than a third of the sale price. A multiple misses fixed fees, so check it here.
- Many check how much has sold against what is still listed. Try the sell-through rate calculator.
Adjust for risk
- A slow seller ties up your money and space, so ask for more profit.
- Items that need cleaning or repair cost time, so add it to your goal.
- Returns and damage do happen, so don’t build your limit on the best sale you found.
