Marketplace Commission Calculator

Marketplace commission fees are the charges online selling platforms deduct from each sale. Every marketplace has a unique fee structure - typically a commission percentage (e.g., Amazon takes 8-20% depending on category, Etsy takes 6.5%), a payment processing fee (usually 2.9% + $0.30 per transaction), and sometimes listing fees (eBay charges $0.35 after 250 free listings, Etsy charges $0.20 per listing). Our Marketplace Commission Calculator compares these fees across platforms so you can see which marketplace delivers the best net proceeds for your specific product price and cost structure.

1. 1. Enter Your Product Details: Start with your sale price, cost of goods (materials, packaging, production), and shipping cost. These inputs form the baseline for calculating net proceeds across all selected marketplaces.
2. 2. Select & Customize Platforms: Choose which marketplaces to compare - Amazon, Etsy, eBay, Shopify, Faire, Walmart, Target+, WooCommerce, BigCommerce, or add a custom platform. Each platform has pre-configured default rates that you can adjust to match your specific seller agreement.
3. 3. Review Ranked Comparison: The marketplace commission calculator shows each platform's net proceeds, total fees, effective fee percentage, and a clear ranking. The best platform is highlighted with a detailed fee breakdown showing commission, processing, and listing fees separately.

• Commission / Referral Fee: A percentage of the sale price that varies by platform and product category. Amazon ranges from 8% (Electronics) to 20% (Jewelry). Etsy charges 6.5% across all categories. eBay varies by category from 10-15%. Shopify does not charge a commission if using Shopify Payments.
• Payment Processing Fee: Usually 2.9% + $0.30 per transaction for most platforms. Some platforms (like eBay) include processing in their final value fee. Etsy charges 3% + $0.25. Shopify Payments charges 2.9% + $0.30 for basic plans.
• Listing / Insertion Fees: Fixed fees charged per item listed. eBay charges $0.35 per listing after 250 free listings (refunded if sold). Etsy charges $0.20 per listing for 4 months. Amazon has no listing fee for most categories.
• Additional Fees: Some platforms have extra charges - Amazon has closing fees for media categories ($1.80), eBay has an international surcharge (1.65%), and most platforms charge subscription fees for seller accounts.

While our Marketplace Commission Calculator provides accurate fee comparisons based on standard rates, actual fees depend on your specific seller agreement, product category, and sales volume. Some marketplaces offer volume discounts for high-selling sellers, reduced rates for certain categories, or promotional fee periods. Additionally, factors like conversion rates (how likely a customer is to buy on each platform), customer acquisition costs, and return rates should be considered alongside fee comparison when choosing where to sell. The calculator focuses on the fee component - combine these results with your marketplace performance data for a complete channel strategy.
