Short answer
The quick math
The under-$15 flat fee can be harsher on low-price items. A $14 Poshmark sale has a $2.95 fee, or about 21.1%. At $15, the standard 20% commission is $3.00. Small price changes near the threshold can matter when margins are thin.
Assumptions used
- $2.95 flat fee under $15
- 20% commission at $15 or more
- Buyer-paid shipping is separate from the seller fee in this calculator
Use it before you decide
- Test likely offer prices, not only the list price.
- Compare $14, $15, and $20 outcomes for low-price closet items.
- Subtract cost of goods before deciding whether to accept an offer.
