Whatnot vs Poshmark: Fees and Fit
Poshmark takes 20 percent. That is the single most important number in this comparison and it does most of the work in the decision.
Whatnot takes roughly 11.2 percent all in. So on the same hundred dollar sale, a Poshmark seller loses nearly nine dollars more than a Whatnot seller, every time, forever. Over a year of steady selling that difference is not a rounding error, it is a holiday.
But fees are never the whole story in resale, and Poshmark has one genuine advantage that keeps sellers there despite the rate.
The fees, side by side
Read from each platform's own published rates on 27 August 2026.
| Whatnot | Poshmark | ||
|---|---|---|---|
| Commission | 8% most categories | 20% on sales of $15 or more | |
| Small sales | same 8% | flat $2.95 under $15 | |
| Processing | 2.9% + $0.30 on total order value | included in the commission | |
| Effective on $100 | about 11.2% | 20% | |
| Sale price | Whatnot | Poshmark | You keep more with Whatnot by |
| $25 | $3.02 | $5.00 | $1.98 |
| $50 | $5.75 | $10.00 | $4.25 |
| $100 | $11.20 | $20.00 | $8.80 |
| $250 | $27.55 | $50.00 | $22.45 |
| $500 | $54.80 | $100.00 | $45.20 |
One quirk worth knowing. Poshmark's flat $2.95 under fifteen dollars is proportionally brutal on cheap items, since a ten dollar sale loses nearly 30 percent, but it is simple and predictable. Whatnot's 30 cent transaction fee behaves similarly at the very bottom end, though less severely.
Where Poshmark genuinely wins
It is asynchronous. A Poshmark listing sits there working while you sleep. Live selling requires you to show up, on camera, at a scheduled time, and be good at it for an hour. For a seller with a job, children, or no appetite for performing, that difference is not a small one and no fee saving compensates for a show you never ran.
The category fit is real. Poshmark is built around clothing, shoes and accessories, and its buyers arrive expecting exactly that. Its social mechanics, sharing, following, offers to likers, do genuine work for a closet-clearing seller.
Shipping is solved and flat. One prepaid label, one price, no thinking. Sellers underrate how much friction that removes.
Where Whatnot genuinely wins
The rate, by a wide margin. Nearly half the take.
Speed of clearance. An hour-long show can move forty items. Forty Poshmark listings is a week of photography and description writing, and they will sell over months.
Prices set by competition. Two people who both want a thing bid against each other, and the price goes where a fixed listing would never have reached. That happens in a live room and cannot happen on a static listing.
A following that compounds. Buyers return to a seller they enjoy watching. Poshmark's follower mechanics exist but do not carry the same weight.
The honest third option
Neither is the cheapest way to sell. A live auction marketplace such as ShopBidz charges sellers 8.8 percent, a 5.9 percent platform fee plus 2.9 percent card processing, and buyers pay 30 cents per charge. Mercari sits at 10 percent and bills its buyers a separate protection fee.
| Platform | Seller pays on $100 |
|---|---|
| ShopBidz | $8.80 |
| Mercari | $10.00 |
| Whatnot | $11.20 |
| Poshmark | $20.00 |
Audience size runs roughly in the opposite direction, which is exactly why fee tables should inform a decision rather than make it.
How to choose
Ask how much time you have, before you ask about fees.
If you can commit to a scheduled hour every week and you do not hate being on camera, live selling pays substantially better per item and per hour, and the fee gap compounds. If you cannot, or you would dread it, a listing platform that works while you are elsewhere is worth its higher rate, because a 20 percent fee on sales you actually make beats an 11 percent fee on shows you never ran.
If you sell clothing specifically, Poshmark's buyer base is genuinely aligned with that, and moving to a platform whose audience is mostly there for cards and collectibles is a real risk regardless of the rate.
Bottom line
Poshmark's 20 percent is nearly double Whatnot's effective 11.2 percent, and on anything above fifty dollars that difference is significant enough to change what selling is worth to you.
Poshmark buys you the ability to sell without showing up. Whatnot buys you speed, competitive pricing and a lower rate, at the cost of an hour of your evening on a schedule. Choose on which of those constraints is actually binding for you, then use the fee difference to break the tie.
