How Poshmark fees work
Poshmark keeps it simple: $2.95 for sales under $15, and 20% for sales of $15 or more. The buyer pays for the prepaid shipping label, so shipping doesn't come out of your earnings.
That 20% is one of the highest fees among resale apps, so Poshmark works best for mid- to high-value items where the bigger audience and offer-to-likers feature help you sell at a good price.
Price with offers in mind
Poshmark buyers often make offers, and sellers commonly send discounted offers to likers. List with room to negotiate, and use your lowest acceptable price in the calculator.
