📚 Profit Calculation Guide
💰 2025 Platform Fees Explained
eBay (13.25% + $0.30): The standard rate for most categories. eBay charges this on the TOTAL amount including shipping and tax collected. Payment processing is included.
Mercari (10% + $0.50): Flat fee structure. They also charge buyers a separate service fee, which doesn't affect your payout.
Poshmark (20% or $2.95): For sales under $15, they take $2.95 flat. For $15+, they take 20%. Shipping label is provided - no separate shipping cost to you.
⚠️ Fees change! eBay adjusts rates by category. Check your actual category fee in Seller Hub before listing high-value items.
📊 Calculating TRUE Profit
Don't forget these hidden costs:
- Packaging: Boxes, tape, poly mailers (~$0.50-2 per item)
- Gas/Mileage: Sourcing trips add up
- Returns: Budget 5-10% of sales for returns
- Supplies: Labels, printer ink, tissue paper
Pro Tip: Add $2-3 to your "Item Cost" field to account for packaging and supplies. Better to underestimate profit than overestimate.
