FAQ
What profit margin should I target when reselling?
Aim for a minimum 50% margin after all costs (purchase price, shipping, fees, packaging). For thrift flips, 3-5x return on cost is achievable. For wholesale arbitrage, 30-40% margin is realistic. Our calculator factors in platform fees automatically.
Which resale platform has the lowest fees?
Facebook Marketplace and local sales have 0% fees. Mercari charges 10%. eBay charges ~13% (12.9% final value + payment processing). Amazon FBA charges 15% referral + fulfillment fees. Poshmark charges 20%. Lower fees don't always mean higher profit — volume and audience matter.
How much can you realistically make reselling?
Part-time (10-15 hrs/week): $500-$2,000/month. Full-time: $3,000-$10,000/month. Top resellers doing wholesale arbitrage or specialized niches (sneakers, electronics) can clear $15K+/month. The bottleneck is usually sourcing, not selling.
