Fees each · net payout each · winner
Estimates use current published eBay and Amazon fee rates. Amazon fulfillment assumes FBA by size tier, eBay assumes standard selling. Store plans, promoted rates, and category exceptions vary, so confirm before you commit inventory.
Want this comparison in your inbox, plus the 3 factors that decide the winner most often?
Sellers pick a home platform and stick with it, assuming the fee math is roughly the same everywhere. It is not.
eBay charges a percent of the sale plus a small per-order fee. Amazon charges a referral percent plus a flat fulfillment fee that climbs with size and weight. On a light, cheap item, eBay's percent-only structure often keeps you more. On a heavier or higher-price item, Amazon's referral rate can beat eBay even with the fulfillment fee stacked on. There is a real crossover point, and it moves with every product.
Guessing which platform pays better leaves money on the table on half your catalog. This tool runs both stacks in one pass and calls the winner.
Price, cost, weight, dimensions, and the category on each platform.
eBay final value fee plus per-order fee, Amazon referral plus fulfillment by size tier.
Net payout on each platform, the dollar difference per unit, and which one keeps you more.
It depends on the product. eBay charges a percent-based final value fee plus a small per-order fee, Amazon charges a referral percent plus a flat fulfillment fee tied to size and weight. On light, low-price items eBay often wins. On heavier or higher-price items it flips. The tool runs both.
Amazon's fulfillment fee is driven by size tier and weight, so dimensions change the number. eBay's fee is a straight percent of the sale plus a per-order fee, so weight does not change it. That difference is why one platform beats the other on some products.
Because Amazon's fee has a fixed fulfillment piece and eBay's is mostly percent-based, there is a price where the cheaper platform switches. Below it one wins, above it the other does. The tool estimates that flip price so you know where your product sits.

Knowing the fee winner only matters if the item sells at the price you assumed on each platform. Before you allocate stock, pressure-test the numbers that drive your real return.
