Marketplace fees can have a major impact on e-commerce profitability. The Amazon and Walmart fee calculator helps sellers estimate how much they actually keep from each sale across major marketplace platforms. It considers selling price, product costs, fulfillment expenses, advertising, storage, shipping, and returns, giving sellers a clearer picture of their overall costs, profit margins, and potential return on investment. 

Amazon FBA and FBM Fee Calculation

For Amazon sellers, the calculator considers factors such as product dimensions, weight, size tier, fulfillment method, referral fees, and applicable fulfillment charges. It can help sellers understand the total cost of selling a product through Amazon FBA or FBM and estimate the resulting profit.

Walmart WFS and Seller-Fulfilled Fees

The calculator also supports Walmart sellers using Walmart Fulfillment Services (WFS) and seller-fulfilled orders. It takes factors such as billed weight, fulfillment charges, storage expenses, and shipping costs into account when estimating profitability.

Advertising, Storage, and Shipping Costs

Marketplace profitability involves more than referral and fulfillment fees. Advertising expenses, inbound freight, storage charges, and shipping costs can significantly reduce margins. Including these expenses gives sellers a more realistic picture of their actual contribution and return on investment.
