Same closet SKU. Two US resale apps. The keep story is processing vs a selling percent, an optional 12% Boost, and two shipping models — not a two-column mill that shouts “Depop 0%, Mercari 10%.” Depop Help still prints no selling fee for US sellers, then takes 3.3% + $0.45 on item + shipping + tax (Depop fees explained). Mercari’s 10% sits on item plus buyer-paid shipping (Mercari fees explained). Ignore processing or Boost and the 0-versus-10 headline is a lie.
Default: $40 item. Shipping empty = $0 in both bases (paste a Mercari 169 cell if you want the same postage dollar on both apps). Depop tax empty = $0 — paste a receipt line; this is not a 50-state engine. Keeps are before COGS. Depop buyer Marketplace fee and Mercari 3.6% are not subtracted. Boost is off until you flip it.
Depop keep from item+ship = (item + pasted ship) − [3.3% × (item + ship + tax) + $0.45] − optional Boost. Boost, if on, is 12% of item, plus shipping only when self-arranged. Mercari keep from item+ship = (item + pasted ship) − 10% × that base. Item leftover on both sides treats the pasted ship as the label cost, then subtracts Mercari Instant Pay. Delta uses those leftovers. Planning only.
A zero-versus-ten headline is the wrong unit. Depop’s published selling fee is 0% for US sellers. The line that actually comes out is payment processing — 3.3% plus a $0.45 flat — on a combined amount that can include shipping and tax the seller never keeps. Mercari’s published selling fee is 10% of a different combined amount (item + buyer-paid shipping), with no separate seller processing percent on new or updated listings. Optional Depop Boost is a third line: 12% that only fires after a boosted interaction and a purchase inside 28 days. Same $40 SKU, organic vs boosted, is a different keep story than the sticker percents.
| Line | Depop US | Mercari US (new / updated listings) |
|---|---|---|
| Seller take | 0% selling fee; 3.3% + $0.45 processing | 10% at any price; no seller processing % |
| Fee base | Processing: item + shipping + any applicable tax | Item + buyer-paid shipping |
| Buyer line (not seller keep) | Marketplace fee up to 5% of item + up to $1 (excludes tax and shipping; shown at checkout) | 3.6% Buyer Protection on item + buyer-paid shipping |
| Optional extra % | Boost 12% on item (ex-tax); shipping joins that 12% only if self-arranged | Promote / Offer to Likers / Time-limited Sale are price drops, not an ad % |
| Prepaid labels | No public US dollar table on How to ship - US (28 Aug 2026) — paste | Dollar table on article 169 — you paste the cell |
| Listing | Not a published US fee on Seller fees and charges | $0 (“listing an item is always free”) |
| Cash-out | US payout article prints no withdrawal fee (gap — do not invent $3) | ACH $0; Instant Pay $3; $2 on failed ACH |
Depop: Seller fees and charges (updated 21 Jul 2026, fetched 28 Aug 2026), Boosted Listings, Marketplace fee. Mercari: Fees on Mercari (article 169) (updated 05/07/2026), article 2517, article 2518. Line-by-line stacks: Depop seller fees explained and Mercari seller fees explained.
Depop Help, “Seller fees and charges,” updated 21 Jul 2026, opened 28 Aug 2026:
“No Depop Selling fees will be charged to sellers based in the UK, US, or AUS.”
The same table’s US processing row is 3.3% + $0.45 via Depop Payments (Stripe), “charged on the item sale price plus shipping costs and any applicable taxes.” The 15 Jul 2024 newsroom note that removed the old 10% US selling fee said “the usual payment processing fee will still apply.” Zero selling fee is not a $0 cost.
Mercari article 169, for listings created or updated on or after 6 January 2025: the seller pays 10% of the combined item price and buyer-paid shipping. Empty shipping in the card is $0 in that base. There is no separate seller payment-processing fee on those new or updated listings. Do not add 2.9% + $0.50 as a current Mercari seller fee — that pair is the legacy buyer-side processing line on pre-6 Jan 2025 listings until updated.
Same $40 sticker, both shipping fields empty, $0 tax, organic:
On $12 empty-ship organic, Depop’s $0.45 flat already bites: 3.3% × $12 = $0.40 + $0.45 = $0.85 (~7.1% of $12), keep $11.15 vs Mercari $1.20 / $10.80. The cheap-sticker story is the flat, not “about 3.3% vs 10%.”
Boosted Listings (updated 24 Jul 2026) and the seller-fees table (US/UK row, footnoted “new listings from 23 March 2026”) both print 12% for US sellers:
You’ll only pay a boosting fee if a buyer interacts with your boosted listing (views, clicks, or likes it) and then purchases the item within 28 days.
Boost is 12% on the item sale price (excluding taxes) and, if you have not used a Depop Shipping label, the shipping cost. It is in addition to processing. Mercari Promote / Offer to Likers / Time-limited Sale (article 347) work by dropping your price — Mercari does not publish an extra ad percent or CPC. Do not invent one and stack it on Mercari’s 10% to “make the compare fair.”
Same $40, $0 ship, $0 tax, Boost fires (Depop label, so shipping is out of the 12% anyway):
Stale 8% wording: an older Help article, I don’t recognise a fee or charge, still mentions an additional 8% Boost fee. Current US published rate on Seller fees (21 Jul 2026) and Boosted Listings (24 Jul 2026) is 12% from 23 March 2026. This card models 12%. Confirm the receipt if a sale started before that date.
Mercari prepaid labels are a published dollar table on article 169 (Ground Advantage and Priority Mail updated 7 May 2026). This page will not reconstruct the whole USPS / UPS / FedEx grid. Quote only labeled cells already parsed on the Mercari explained page — paste the cell that matches the listing:
| Labeled 169 cell (opened 27 Aug 2026) | Printed rate |
|---|---|
| USPS Media Mail 1 lb / 2 lb / 3 lb | $4.99 / $5.99 / $6.99 |
| USPS First-Class Envelope (trading cards only) 1 oz / 2 oz / 3 oz | $0.74 / $1.03 / $1.32 |
| USPS Ground Advantage 0.25 lb (Best vs Standard) | $4.91 / $5.49 |
| USPS Ground Advantage 1 lb (Best vs Standard) | $7.48 / $7.59 |
If the buyer pays that Mercari label, the cell sits in the 10% base. The $7.48 Best Ground Advantage 1 lb row is a labeled cell, not a “typical shipping” guess.
Depop How to ship - US describes Depop Shipping via USPS versus “Other” (you arrange tracked shipping). That article did not print a public US weight-tier dollar table on the fetch of 28 Aug 2026. Gap, same class as Poshmark’s unread Fee Policy: blogs quote unofficial ~$4.49 / ~$7.69 style tiers. This page will not. The $7.48 preset reuses Mercari’s 169 cell as a same-SKU shipping dollar pasted onto Depop processing — it is not a Depop official rate.
$40 + $7.48 ship, $0 tax, organic:
Flip Boost on with a Depop Shipping label (shipping out of the 12%): processing $2.02 + Boost $4.80 = $6.82 out of $47.48, keep $40.66, leftover $33.18 vs Mercari $35.25 — Mercari leads by $2.07. Self-arranged shipping puts $7.48 inside Boost too: 12% × $47.48 = $5.70, leftover $32.28. Processing still follows shipping either way (Help’s processing cell does not carve out Depop labels).
Mercari overage is a different trap: article 172 bills the seller the extra weight (or zone-6 residential retail if Mercari has no cell; $2,500 over 150 lb). An 8% penalty on the total adjusted shipping price for underpaid labels was announced on article 485 (18 Feb 2025 entry, starting 10 Mar 2025). Articles 169 and 172 did not restate that 8% in the text opened 27 Aug 2026. Confirm a statement line in your Mercari account.
Do not subtract Depop’s Marketplace fee or Mercari’s 3.6% Buyer Protection from seller keep. What is the Marketplace fee? (updated 21 Jul 2026) applies to US and UK buyers buying in USD or GBP: up to 5% of the item purchase price plus a fixed amount of up to $1, excluding taxes and shipping. Exact amount is shown at checkout. Help does not publish one exact percent — this card will not invent 4.2% or any other unofficial midpoint. Mercari articles 169, 2517, and 2518 put 3.6% on the buyer at checkout (item + buyer-paid shipping). A $40 sale is not “Depop 3.3% + $0.45 + 5% + $1” or “Mercari 10% + 3.6%” off the seller. Mixing them is how blogs overstate both takes.
Depop State Sales Tax in the US (updated 2 Feb 2026) says Depop calculates, collects, and remits US sales tax as a marketplace facilitator, and that the tax element is included when calculating the Payment Processing fee. Mercari’s published 10% base is item + buyer-paid shipping — tax is not added to that 10% on article 169. Leave tax empty ($0) unless you are pasting a receipt line. This page will not clone a 50-state tax engine.
Cash-out is the other non-percent line. Mercari: successful ACH is $0 once per day; Instant Pay is a $3 flat (once per day, up to $600/month, about 30 minutes); failed/rejected ACH is $2 non-refundable. Depop How do I get paid? - US (updated 12 Aug 2026): funds hit Depop Balance 2 business days after delivered or 10 business days after the sale, whichever comes first, then up to 5 days to the bank after withdraw. Gap: that article does not publish a withdrawal fee. This card does not subtract a Depop cash-out flat. Leave Instant Pay at $0 unless you actually tap it on Mercari — on a $12 sale, $3 is a large bite relative to Mercari’s $1.20 selling fee, and Depop still has no published withdrawal fee to match it.
$40 item, $0 ship, $0 tax, organic, ACH / no published Depop withdrawal fee
$40 + $7.48 shipping (1 lb Best Ground Advantage cell from Mercari article 169, pasted as the same dollar on Depop — not a Depop official rate)
$40, $0 ship, Boost 12% fires (Depop label / shipping out of Boost)
$12 listing (Depop $0.45 bite), $0 ship, organic
Flip Mercari Instant Pay to $3 on that $12 organic run and Mercari remaining leftover is $7.80 vs Depop $11.15. Depop still has no published withdrawal fee to subtract. Confirm a bank line if your Depop statement ever shows one.
No hype — processing, Boost, and the shipping dollar decide, not the brand of app.
Volume, Mercari Authenticate $5 / $15, cancelation 5% ($25 max) after warnings, Depop bundle processing-once, and returns are outside this SKU snapshot. Put those on the explained pages, not as a blended resale tax.
Same SKU on Poshmark is a third stack — $2.95 under $15 or 20% of listing price, shipping not in that % on get-started: Mercari vs Poshmark. Handmade / Amazon referral: Etsy vs Amazon seller fees. eBay is a category-table stack: eBay fees explained.
Not as a slogan. $40 / $0 ship organic: keep $38.23 vs Mercari $36.00 ($2.23). Boost 12%: Depop $33.43 vs Mercari $36.00. $40 + $7.48 Mercari 169 cell (pasted as the same dollar on Depop): leftover $37.98 vs $35.25 organic; $33.18 vs $35.25 with Boost (Depop label). Last checked 28 Aug 2026. Confirm in each seller account.
Depop yes — processing 3.3% + $0.45 on item + shipping + tax. Mercari yes — 10% of item + buyer-paid shipping (article 169). Depop How to ship - US printed no public US label grid on 28 Aug 2026; paste. Mercari cells are the 169 table.
It can. 12% of item (plus shipping if self-arranged), only if a buyer interacted with the boosted listing and bought within 28 days. $40 empty-ship: Boost $4.80 + processing $1.77 = $6.57 vs Mercari $4.00. Current US rate is 12% from 23 March 2026, not the stale 8%.
No. Depop Marketplace fee is up to 5% of item plus up to $1, excluding tax and shipping, shown at checkout. Mercari 3.6% is a buyer checkout line. Do not subtract either from seller keep.
Neither, on the pages we opened. How to ship - US had no dollar grid (28 Aug 2026). How do I get paid? - US prints no withdrawal fee. Do not invent unofficial label tiers or copy Mercari Instant Pay $3 onto Depop. Mercari’s 8% underpaid-label penalty lives on article 485 and was not reprinted on 169/172 (27 Aug 2026).
