Frequently Asked Questions (FAQ)
How do I calculate net profit when flipping items?
Net profit is calculated as: (Selling Price + Buyer Paid Shipping) - Platform Fees - Cost of Goods Sold (COGS) - Seller Paid Shipping.
Why does Poshmark take a flat 20% commission?
Poshmark covers buyer/seller protection and simplifies shipping labels through USPS Priority Flat Rate, absorbing operational logistics into their 20% flat fee structure.
Which platform has the lowest selling fees for cheap items?
For items priced under $15, platforms charging percentage-based rates (like eBay or Mercari) often yield higher net margins than Poshmark's $2.95 minimum charge.
