Reselling sneakers, streetwear, and collectibles on StockX requires tracking tiered commission percentages, payment processing deductions, and inbound shipping expenses to maintain healthy profit margins. This calculator computes your exact seller transaction fee based on your active seller tier (Levels 1 through 5), calculates payment processing, and determines net cash payout and profit margins.

### How StockX Seller Deductions Are Structured The calculator applies official StockX seller fee schedules: - **Seller Tier Transaction Fee**: Ranges from 9.0% for Level 1 sellers down to 7.0% for high-volume Level 5 power sellers: - Level 1: `9.0%` - Level 2: `8.5%` - Level 3: `8.0%` - Level 4: `7.5%` - Level 5: `7.0%` - **Payment Processing Fee**: StockX deducts a standard flat `3.0%` payment processing surcharge on the gross sale price across all seller tiers. - **Inbound Shipping Surcharge**: Standard flat shipping fee (typically `$4.00` per domestic sneaker box) deducted from final seller payout. - **Net Payout & Profit**: `Net Payout = Sale Price - (Transaction Fee + Processing Fee + Shipping)`. Net profit subtracts your original purchase cost (COGS).

### Worked Resale Calculation Selling a limited-edition sneaker for **$280.00** as a **Level 1 seller (9.0%)** with an original retail purchase cost of **$160.00** and standard **$4.00 shipping**: - **Transaction Fee**: `$280.00 × 9.0% = $25.20` - **Payment Processing Fee**: `$280.00 × 3.0% = $8.40` - **Shipping Deduction**: `$4.00` - **Total Fees Deducted**: `$25.20 + $8.40 + $4.00 = $37.60` - **Net Payout Received**: `$280.00 - $37.60 = $242.40` - **Net Profit**: `$242.40 - $160.00 = $82.40` (29.43% net profit margin).
