I built this reseller fee calculator hub because I was sick of doing the same math twelve different ways. eBay quotes percentages of the "total amount of the sale," Poshmark a flat $2.95 or 20%, Depop says "no selling fees" and means 3.3% plus 45 cents. After 30,000-plus orders since 2011, I translate fee dialects in my head. You shouldn't have to.
The tool above takes one set of numbers — price, shipping, label, item cost — and ranks twelve selling platforms and payment tools by what actually lands in your account. Not by headline rate. By net. Below: where the rankings flip, and the costs no fee schedule shows.
How to compare selling fees with one set of numbers
To compare selling fees fairly, every platform has to get the same sale. Almost nobody does that, because the fee bases don't line up: eBay's percentage covers item, shipping, and sales tax; Mercari's covers item plus buyer-paid shipping; Poshmark's touches the item price only. Different slices make the comparison fiction.
So the compare tool feeds identical inputs into twelve real formulas — every threshold, minimum, and fixed fee included — and ranks the outputs by take-home. Buyer shipping gets its own field because some platforms fee it; the label and item-cost fields exist because fees aren't your only cost. One warning: the order isn't stable.
The cheapest platform to sell on changes with your price
There is no single cheapest platform to sell on — the ranking reshuffles as the price climbs, and the engine's own output proves it. At $25, Mercari beats Etsy, $22.50 to $22.17. At $250, Etsy wins, $225.80 to $225.00, because Etsy's fixed fees fade to nothing on a bigger sale while Mercari's 10% never relaxes.
Whatnot and Grailed flip twice. At $25, Whatnot nets more ($21.97 vs $21.65) because Grailed's $1.99 minimum commission punishes small sales. At $100, Grailed leads, $90.02 to $88.80. By $250 the lead is gone — $218.28 to Whatnot's $222.45 — because Grailed's commission jumps from 6% to 9% once an item crosses $120, a tier introduced May 20, 2026.
| Platform | Net on a $25 sale | Net on a $250 sale | Effective rate, $25 → $250 |
|---|---|---|---|
| Depop | $23.72 | $241.30 | 5.12% → 3.48% |
| TikTok Shop | $23.50 | $235.00 | 6.00% → 6.00% |
| Mercari | $22.50 | $225.00 | 10.00% → 10.00% |
| Etsy | $22.17 | $225.80 | 11.32% → 9.68% |
| Whatnot | $21.97 | $222.45 | 12.12% → 11.02% |
| Grailed | $21.65 | $218.28 | 13.40% → 12.69% |
| eBay | $21.20 | $215.60 | 15.20% → 13.76% |
| Poshmark | $20.00 | $200.00 | 20.00% → 20.00% |

The take that gets me yelled at in reseller groups: the scary-looking rate is sometimes the better deal. Grailed advertises 6% — friendliest headline in the clothing group — yet at $25 its minimum commission and processing stack to 13.40% effective, a worse net than Whatnot's uglier-looking 8% plus processing. And "zero-fee" Depop with boosting on carries 16.8% on a $30 sale. Percentages are marketing. Nets are math.
And Poshmark? Its 20% finishes last in every one of these tables. But flat fees punish the bottom end harder: under $15, Poshmark charges $2.95 flat — 29.5% on a $10 sale, the worst take here. A percentage without a price tells you nothing. The Poshmark fee calculator maps the $15 crossover, including the dead zone where a higher price nets less.
One marketplace fee calculator for every platform, same engine underneath
The compare table tells you where; the platform pages tell you why. Each is a marketplace fee calculator on the same tested engine, plus what a single row can't hold — category rates, Store tiers, boost toggles, a reverse mode that solves "what do I list at to net $50." Here's the map, with the column that trips up most sellers: what each percentage is actually charged on.
| Platform | Headline fees | What the percentage is charged on |
|---|---|---|
| eBay | 13.6% + $0.30–$0.40 per order | Item + buyer-paid shipping + sales tax |
| Etsy | $0.20 listing + 6.5% + 3% + $0.25 | Transaction fee on item + shipping |
| Poshmark | $2.95 under $15 · 20% at $15+ | Item price only |
| Mercari | 10% selling fee | Item + buyer-paid shipping |
| Depop | 0% selling fee + 3.3% + $0.45 processing | Item + shipping (+12% if boosted) |
| Grailed | 6% (min $1.99) under $120 · 9% at $120+, plus 3.49% + $0.49 | Commission on item; processing on item + shipping |
| Whatnot | 8% + 2.9% + $0.30 | Commission on item; processing on item + shipping + tax |
| TikTok Shop | 6% referral fee | Item + buyer shipping (tax excluded) |
| Stripe | 2.9% + $0.30 online card | Full charge amount |
| Square | 2.6% + $0.15 in person · 3.3% + $0.30 online | Payment amount |
| Venmo | 2.99% goods & services · 1.9% + $0.10 business | Payment amount |
| Cash App | 0.5%–2.5% instant deposit · 2.6% + $0.15 business | Deposit or payment amount |
| Copart | Tiered buyer fee + virtual bid fee + $109 fixed | Added on top of your winning bid (buyer side) |
If you bookmark one spoke, make it the eBay fee calculator. eBay is where most cross-listers end up, and it hides the most category quirks — athletic shoes at $150 or more pay a flat 8% with no per-order fee, so a $149 pair costs $20.66 in fees while a $200 pair costs $16.00. The cheaper item pays more.
The fee nobody counts
Platform fees are the visible cost. Shipping labels are the silent one, and item cost surfaces only at tax time.
Take a $50 sale on eBay with free shipping. The table says you net $42.80, and it's right — about platform fees. Buy a $9 label and you're at $33.80. If the jacket cost $12 to source, actual profit is $21.80. Fees took $7.20 of that sale; the label took $9. The biggest "fee" never appeared on any fee page.
Charging the buyer for shipping helps less than you'd think, because on eBay and Mercari the percentage applies to buyer-paid shipping too. Charge $10 shipping on a $100 eBay sale and net moves from $86.00 to $94.64 — $1.36 of that shipping charge went to eBay, not the post office. That's why the compare tool asks about shipping twice: what you charge, and what the label costs you.
Why "no-fee" platforms still cost you
No platform runs free — when the selling fee is zero, the cost moved into processing, deposits, or the buyer's side of the receipt.
Depop is the textbook case. It dropped its 10% selling fee on July 15, 2024 — two years ago today — but payment processing stayed: 3.3% + $0.45 on item plus shipping, $1.28 on a $25 sale. That's 5.12%. Lightest marketplace take on this page, and still not zero. Turn on boosting (12% since March 23, 2026) and a boosted $30 sale carries $5.04 in fees — 16.8%. Buyers also pay Depop up to 5% + $1 on their side. The Depop fee calculator handles both toggles.
Mercari is the cautionary tale: $0 seller fees in March 2024, then a 10% selling fee back on January 6, 2025 — now applied to item plus buyer-paid shipping. "Free" lasted just over nine months.
Then the payment apps resellers treat as fee-free exits. Venmo goods and services takes 2.99% — $2.99 on a $100 sale, per the Venmo fee calculator — plus 1.75% for instant transfer. Cash App standard deposits are free, but instant deposit runs 0.5%–2.5%, a ceiling raised from 1.75% in early 2026; the Cash App fee calculator computes both endpoints.
Why trust this reseller fee calculator
Two reasons: the engine is tested against the platforms' own worked examples, and the rates get re-verified on a schedule instead of a vibe.
Every formula has to reproduce official published examples to the cent before it ships — 42 of 42 known-answer tests pass, rounded per fee line the way payout statements do it. Every calculator reads from one shared rates config, so a correction lands everywhere at once.
Then there's the freshness problem. Fee pages rot: eBay moved most categories from 13.25% to 13.6% on February 14, 2025, and some calculators ranking on Google today still show the old number. So I re-verify every schedule quarterly against the official fee pages — the dated stamp on each calculator is real — and every change lands with its effective date on the fee changes log. The full method, and who I am, is on the about page. If your payout statement ever disagrees with a number here, tell me — that's a bug, and bugs get logged.
Frequently Asked Questions
Is this reseller fee calculator accurate?
It's tested, not eyeballed. Every formula is anchored to the platforms' own published examples — Whatnot's official worked example says a $50 item should leave you $44.00 after the $4.00 commission and $2.00 processing, and the engine has to reproduce that to the cent. It passes 42 of 42 known-answer tests like that one, rounding per fee line the way payout statements do, so results land within $0.01 per line. Two honest limits: add buyer-paid tax to the shipping field for penny-exact Whatnot results, and Cash App sets its instant deposit rate per transaction, so I compute both the 0.5% and 2.5% endpoints.
Which platform is cheapest for selling clothes?
For a $30 clothing item with no shipping charged, the engine ranks it: Depop nets $28.56, Mercari $27.00, Grailed $26.47, eBay $25.52, and Poshmark $24.00. On pure fees, Depop wins — 3.3% + $0.45 processing is the lightest touch in clothing resale. But fees aren't the whole decision: Poshmark's buyer pool is built for clothes, Grailed only makes sense for menswear, and Grailed's commission jumps from 6% to 9% once a piece crosses $120. My rule after fifteen years of vintage denim: pick the platform where the item actually sells, then price it so the net still works.
Which platform is cheapest for trading cards?
Run the math three ways. TikTok Shop's collectibles referral fee is 6% — a $100 card nets $94.00, the best take of the three. Whatnot charges 8% commission plus 2.9% + $0.30 processing, about 11.2% effective on a $100 sale, netting $88.80 — and live breaks are where card volume actually moves. eBay's trading cards category was exempt from the February 14, 2025 fee increase, so it still pays 13.25% instead of the standard 13.6%; a standard-category $100 sale nets $86.00, and a card does slightly better. I list slabs on eBay for search traffic and run singles through Whatnot lives — an unsold card nets zero everywhere.
Do the fees include shipping?
It depends on the platform, and it's the number-one thing sellers get wrong. eBay charges its final value fee on item plus buyer-paid shipping plus sales tax, and Mercari's 10% applies to item plus buyer-paid shipping — charging more for shipping doesn't dodge fees on either. Poshmark fees the item price only. Depop and Whatnot run processing on item plus shipping (Whatnot includes tax in that base too), while TikTok Shop's 6% covers item plus buyer shipping but excludes tax. The compare tool has a separate field for buyer shipping so each fee base is handled correctly; your own label cost is a separate input.
How often are these rates updated?
Quarterly, at minimum. I re-verify every platform's schedule against its official fee page and stamp the date on each calculator — everything here was last verified July 15, 2026. Changes in between get recorded with their effective dates on the fee changes log: eBay's February 14, 2025 increase to 13.6%, Grailed's May 20, 2026 move to 9% above $120, Depop's 12% boost fee from March 23, 2026. Fee pages rot quietly — some calculators ranking on Google today still show eBay rates that died in early 2025 — so the verified date is the first thing to check on any fee tool. Including mine.
