Selling on Amazon vs eBay: Which Wins for Resellers in 2026

You picked up a stack of items to flip. Now you're staring at two upload screens, wondering which platform actually pays off. Amazon and eBay are not interchangeable storefronts — they run on different economics, different shopper habits, and different definitions of a "win." Here's the actual math.

How the Fees Stack Up

Amazon charges around 15% referral fee on most categories, plus a $39.99/month Professional plan if you're selling more than 40 items a month. Add FBA fulfillment and storage fees on top if Amazon is boxing and shipping for you. eBay runs final value fees between 12.7% and 15.3%, no required monthly subscription, and 250 free listings a month before insertion fees kick in. On paper, eBay looks cheaper to start. In practice, Amazon's fee buys you placement in front of buyers who are already reaching for their wallet.

Two Different Shopping Behaviors

Amazon's average conversion rate runs 10-15%. eBay's sits at 2-5%. That gap isn't about product quality — it's about intent. Amazon shoppers land on a single listing page (the Buy Box) already decided on what they want; they're comparing sellers, not products. eBay shoppers are still browsing, scrolling past ten similar listings, judging photos and titles before they click buy. Amazon behaves like a product catalog. eBay behaves like a marketplace crossed with an auction house.

What the Ceiling Actually Looks Like

Top sellers give a sense of scale, not a target. In 2026, Amazon's top sellers average around $1.14 million a month in revenue. eBay's top sellers average closer to $125,000. Etsy sits in between at roughly $174,000. These numbers describe the outliers, not the median reseller — most people flipping thrifted goods will never touch them. But they do reveal what each platform rewards: Amazon favors deep, repeatable inventory with clean UPCs. eBay and Etsy favor curation, story, and one-of-one finds.

Matching the Platform to What You Actually Sell

This is the part most new resellers skip. If you're moving single vintage pieces, thrifted one-offs, or anything without a scannable barcode, eBay's browsing crowd is a better match for your inventory. If you're sourcing case lots, closeout pallets, or anything with a repeatable UPC and multiple units, Amazon's catalog model does more of the selling for you. A lot of serious resellers run both — new-in-box duplicates go to Amazon, the weird one-off finds go to eBay.

Before you commit a piece to either platform, it's worth scanning it and pulling recent sold comps across both marketplaces — an app like ThreadFlip does this in a few seconds — rather than guessing which audience will actually pay for it.

The Bottom Line

There's no universal winner here. Run the fee math on your actual price point, then let the item itself decide the platform. A $12 vintage tee and a sealed case of 24 identical phone cases are not the same business, and they shouldn't be listed the same way.
