Our Methodology
At FlipCalc, our goal is to eliminate the guesswork of selling online. Different reselling marketplaces use complex, varying fee schedules that include fixed order costs, percentage-based final value fees, region-dependent transaction charges, and buyer protection fees. We built FlipCalc to provide instant, real-time comparisons so you can determine the most lucrative sales channel for your inventory.
Our mathematical formulas strictly adhere to the official public fee guidelines of each supported platform:
- Vinted: 0% seller commission fees, utilizing prepaid buyer-funded shipping label models.
- Depop: 0% listing selling fees in the US and UK, accounting for standard payment processing (2.9% + $0.30/£0.30) and applying 10% commission in non-US/UK regions.
- eBay: 13.25% average clothing/fashion category fees, plus a flat $0.30 per-order transaction charge.
- Poshmark: Flat $2.95 commission for items under $15, and 20% flat commission for items $15 and over (inclusive of credit card/transaction fees).
- Mercari: Standard 10% seller fee with free listing capabilities.
