Seller Revenue Calculator

Seller revenue is the total income generated from product sales before deducting costs. Gross revenue = Units Sold � Selling Price. Net revenue = Gross Revenue - (Platform Fees + Refunds + Promotional Discounts + Payment Processing Fees). Understanding the difference between gross and net revenue is critical � platform fees alone can reduce take-home revenue by 8-25% depending on the marketplace.

Platform take rate is the percentage of your gross sales that the marketplace keeps in fees. Amazon's take rate averages 15-25% (referral fee + fulfillment), eBay's is about 13.25%, Etsy's is about 11.5% (transaction + processing), and Walmart's is 8-15%. The take rate directly reduces your net revenue.

Refunds directly reduce revenue by returning the full purchase price to the customer. Additionally, most platforms do not refund their commission (fees are still charged on refunded orders), and payment processors charge chargeback fees ($15-25 each). A 10% refund rate effectively reduces your revenue by 10-15% when accounting for non-refundable fees.

Promotional discounts reduce the effective selling price and therefore net revenue. While promotions can increase volume, the impact on revenue depends on the elasticity of demand. A 20% off promotion needs at least 25% more unit sales to maintain the same gross revenue. Calculate the break-even volume increase needed before running promotions.

To increase net revenue without raising prices: reduce return rates (better product photos, accurate sizing guides), optimize for fewer chargebacks (responsive customer service), negotiate lower platform fees (volume-based discounts on some platforms), minimize promotional discounting, bundle products to increase AOV, and use cross-selling/upselling to add items to existing orders.
