CrosslistyListing price calculator: what to charge on each marketplace
Enter the profit you want, what you paid and your shipping. The calculator works backwards through each marketplace’s fees to the price you need to list at. You can’t simply add a percentage, because fixed fees and minimums get in the way.
The shortcut: Crosslisty lets you copy one listing to many marketplaces and adjust the price for each.
Add to Chrome, free- The same profit takes a different price on each marketplace.
- Dividing by one minus the fee rate misses fixed fees, so work it out properly.
- Add room for offers on marketplaces where buyers expect to haggle.
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.
Why adding 20% gets it wrong
If Poshmark takes 20% and you need $40, adding 20% gives $48, and 80% of $48 is $38.40. You come up short. The right sum is $40 divided by 0.8, which is $50. Fixed fees and minimums make it harder still, so this calculator tries prices until it finds the lowest one that works.
Allow for offers
- Poshmark and Mercari buyers often make offers, so list above your lowest acceptable price.
- Work out your floor with the Poshmark offer calculator.
- Set a price buyers can compare. A much higher price on one marketplace may just move the sale elsewhere.
Should every marketplace have a different price?
Not always. A single price is simpler and looks consistent, but it earns less on high-fee marketplaces. Many sellers set a base price and add a little where fees are highest. Check what similar items sold for on each marketplace, as buyers there set the real ceiling.

Questions
How do I work out a selling price with fees?
Decide what you need to keep, then divide by one minus the percentage fee, after adding any fixed fee. Or enter your numbers above and let the calculator do it.
Does this include shipping?
Enter what you pay for shipping and it is included in the amount to recover. Buyer-paid shipping is not included.
What if the price is above what the item sells for?
Then the numbers don’t work on that marketplace. Try another one, or buy for less next time with the max buy price calculator.
