There's no universal answer — profitability depends on your specific referral fees, fulfillment costs, advertising efficiency, product cost, selling price, return rate, and sales volume on each platform. This calculator is built to give you an honest comparison using your own numbers rather than a generic industry claim. ## Amazon vs Walmart Fees Both marketplaces charge a referral fee that varies by category, plus fulfillment costs if you use their managed fulfillment programs (FBA for Amazon, WFS for Walmart). These vary by product category, weight, dimensions, and fulfillment method — the defaults in this calculator are example assumptions to get you started, not universal rates. Always verify your actual fees in each marketplace's seller dashboard before making a decision. ## Does ROAS Determine Profitability? No. ROAS (Return on Ad Spend) only measures revenue generated per advertising dollar — it says nothing about product cost, marketplace fees, fulfillment, or returns. A campaign can post an impressive ROAS and still be unprofitable once every other cost is accounted for. That's why this calculator centers on contribution profit and break-even ACOS/ROAS rather than ROAS alone.

It depends entirely on your product's costs on each platform. Walmart's referral fees and fulfillment costs are often — but not always — lower than Amazon's, while Amazon typically has a larger addressable audience. Run your own numbers above rather than relying on a general claim. How do I calculate Amazon profit? Subtract COGS, referral fees, FBA fulfillment, storage, advertising spend, returns, and other variable costs from your revenue. What remains is contribution profit — the number that actually matters, not just revenue or ROAS. How do I calculate Walmart profit? The same framework applies: revenue minus COGS, Walmart referral fee, WFS fulfillment (if used), advertising, returns, and other costs. Walmart's fee structure and fulfillment costs differ from Amazon's, so don't assume your Amazon margin will carry over directly. What is a good marketplace profit margin? This varies widely by category, but many sellers target 15-30% net contribution margin after all marketplace costs. Below 10% leaves little room for cost fluctuations or price competition; above 30% is strong for most product categories. Should Amazon sellers expand to Walmart? Expansion makes sense when the incremental profit opportunity is meaningful relative to the operational cost of managing a second channel — inventory, listing management, and customer service. Use the Walmart Expansion Opportunity section above to model whether the incremental profit justifies that overhead for your specific product. ## FAQ ### Is Walmart more profitable than Amazon?
