A reader emailed me last month with a simple question: "I sold a $20 item and only got $16. Where did my four dollars go?" The answer was that he had sold on a platform without ever reading the fee schedule, which is like renting an apartment without asking the rent. Fees are not hidden — they are just boring, so most sellers skip them until the payout surprises them. Let us fix that now, platform by platform, using the kind of clearance goods we actually sell.

One honesty note before the numbers: platform fees change, sometimes twice a year, and promotional rates muddle everything. Treat the figures below as the working ballpark I use for planning in late 2026, then verify the current schedule on each platform before you commit your pricing. And because fee awareness only matters alongside sourcing math, the full lot catalog and its terms live behind the standard ordering process — knowing what a platform takes starts with knowing what you paid.

For ongoing fee-watch reading, the Insights section covers market-structure topics like this one, and the analysis below continues platform by platform.

eBay: The Predictable Workhorse

eBay charges most sellers a final value fee of roughly 13-14% of the total order including shipping, plus a fixed per-order charge around $0.30. On a $20 sale that is about $2.90 gone. Add optional listing upgrades and promoted listings, and your effective take can climb a few points.

What you get for that cut is the most liquid buyer base for oddball clearance goods. A vintage kitchen gadget, a single plush from a mixed set, a replacement part — eBay has a buyer for nearly everything, and sold listings give you free market research. For one-off flips from mixed lots, I still consider eBay the default. The fee stings less when the item would not sell anywhere else.

Amazon: High Fees, High Ceiling

Amazon's referral fees run roughly 8-15% depending on category, plus either a $0.99 per-item charge on an individual selling plan or a $39.99 monthly professional plan. FBA fulfillment adds its own picks, packs and storage costs. On that same $20 item, a realistic all-in Amazon cost can reach $4-6 before you count inbound freight.

So why bother? Because Amazon buyers convert at rates no other marketplace matches, and branded-adjacent clearance — accessories, compatible replacements, consumables — can hold a $20-30 retail price there all day. The 4-pack ice cream pint containers at $2.50 wholesale is exactly the profile: a compatible accessory for a popular appliance, bought at one-eighth of the accessory retail price. On Amazon the fee is heavy; the price ceiling makes up for it. On FBM (merchant fulfilled) from domestic stock, you skip FBA's warehouse fees entirely, which is how most clearance sellers run Amazon.

Whatnot: Cheap Fees, Fast Clock

Whatnot's commission sits around 8% plus payment processing, meaningfully cheaper than eBay on paper. The catch is the format: live auctions. Your inventory must survive a camera demo, your evenings must survive a show schedule, and unsold lots come back off camera with their time wasted.

Where Whatnot shines for clearance is velocity on demo-friendly goods. A 6-piece plush set at $4.40 breaks into singles that auction with energy; a vacuum sealer demo moves units in ninety seconds. Our deeper Whatnot breakdown covers the show-format realities — treat the fee as the smallest part of that decision.

Facebook Marketplace: Free Until It Isn't

Local cash-or-pickup sales on Facebook Marketplace cost nothing — no commission, no payment processing. That is unbeatable for bulky pickup goods like furniture or the kind of $1.20 warehouse kitchen racks that make no sense to parcel-ship. The moment you enable shipping, Facebook takes a selling fee (around 5% for shipped orders, with a flat minimum on cheap items), and the no-fee advantage shrinks.

The hidden cost of Marketplace is time: no-shows, lowball messages, and rebooking pickups eat hours that eBay's checkout never does. I price that time in. For local surplus and heavy items, it stays my first call; for anything parcel-sized, I usually let the platforms with real checkout handle it.

Payment Processing: The Fee Nobody Reads

Beside the platform commission sits payment processing — usually 2.9% plus about $0.30 per transaction — and it applies on most channels even when the platform fee feels low. Facebook Marketplace local sales paid in cash dodge it entirely; everything that runs a card does not. On small-ticket items the fixed 30 cents hurts proportionally: on a $6.99 sale, processing alone is over 7% before the commission even starts. This is the quiet argument for bundling cheap units into multi-packs rather than listing them single — one payment event, one fixed fee, spread across three units instead of one.

There is also the settlement lag to plan around. Platforms hold and batch payouts on different schedules, and a reseller running reinvestment loops — sell, rebuy, relist — needs to know when money actually lands. Cash-flow timing is part of your real fee structure, even though no fee schedule lists it. Our pricing guide treats settlement timing as part of the buy-sell-rebuy cycle for exactly this reason.

The Side-by-Side That Actually Matters

Raw percentages mislead. What matters is effective cost per channel for your specific item:

  • Oddball one-offs, unknown demand: eBay. The 13% buys access to the only buyers who want a 2012 bread maker paddle.
  • Consumables and compatible accessories at scale: Amazon FBM. Heavy fees, but the price ceiling and conversion rate beat everything.
  • Demo-friendly, visual, fun goods: Whatnot. Cheapest fees and fastest pace, if you can work a camera.
  • Bulky, local, pickup-grade stock: Facebook Marketplace local. Zero fees beat everything, if you can tolerate the scheduling dance.

Running the Numbers Before You Buy

The mistake I made for too long was choosing the platform after buying the inventory. Reverse it: before you spend on a lot, model the net. Buy price plus inbound cost, minus platform fee, minus shipping and supplies, equals your real margin. Our margin calculation walkthrough and the clearance pricing guide both build that math step by step, and the fee comparison table in this article slots straight into it.

A concrete example: the cleaning kit at $1.40 with 7,000 units supports a MOQ of 50. At a $6.99 eBay sale, roughly $1.25 goes to fees; the same sale on Whatnot costs closer to $0.75. Over a thousand units, that difference is a car payment. Deep stock is where fee optimization compounds — thin one-off flips, less so.

The broader takeaway from our look at where returned inventory goes is that clearance sourcing gives you margin headroom other sellers do not have. Spend that headroom deliberately: pick the platform whose fee structure matches the item, not the one you happen to have an account on. And if you are still choosing a lane, our eBay vs Facebook vs Whatnot seller guide goes channel by channel from the reseller's chair rather than the spreadsheet.

Frequently Asked Questions

Which platform has the lowest fees overall?
Facebook Marketplace for local pickup sales — zero commission beats everything. Among shipping platforms, Whatnot's roughly 8% plus processing usually undercuts eBay's 13%+, but only for items that suit live selling.

Is an Amazon professional account worth $39.99 a month?
Only if you list more than about 40 items monthly. Below that, the individual plan's $0.99 per-item fee is cheaper. The math flips fast once clearance volume builds.

Do promoted listings change the fee math?
Yes, and often invisibly. An extra 2-6% ad rate on eBay can erase a thin margin. I only promote listings where the item has at least a 2.5x markup over total cost.

Can I sell the same lot on multiple platforms?
You can, but track stock religiously — overselling on two platforms at once is a refund-and-apology spiral. Our 10-minute inventory tracking sheet exists precisely for this.
