Put eBay and Mercari side by side and the contrast isn't really fashion versus general merchandise, both sell nearly everything. It's complexity versus simplicity, at very different scales. eBay's fee sits around 13.6% for most categories but ranges from 2.5% to 15.3%, then shifts again based on seller performance and whether you pay for a Store subscription. Mercari charges a flat 10% no matter what you sell, full stop. That simplicity comes at a cost of its own: Mercari ships within the US only, while eBay reaches a buyer base roughly ten times its size across the globe. Neither platform is the obvious answer for every seller; the right one depends on whether predictability or reach matters more for what's in your closet, a question our wider guide to choosing the right resale marketplace can help frame before you get into the specifics below.
| eBay | Mercari | |
|---|---|---|
| Selling fee | 13.6% for most categories (range 2.5%–15.3%) + $0.30/$0.40 per order | Flat 10% on item price + buyer-paid shipping |
| Payment processing | Included via Managed Payments | None, removed as of January 2025 |
| Shipping | Seller picks calculated, flat, or free; fee applies to the shipping charge too | Flat, weight-tiered nationwide rate, no zone pricing |
| Reach | Global, ships internationally, ~136M active buyers | US only (50 states + DC), roughly 23M monthly active users |
| Listing format | Fixed price and live auctions | Fixed price with buyer offers only |
| Authentication | Authenticity Guarantee, free, physical inspection, mandatory above category thresholds | Mercari Authenticate, $5 flat, photo-based, third-party review |
eBay's final value fee runs 13.6% for most categories, but that headline number moves: some categories run as low as 2.5%, others as high as 15.3%, and a $0.30 or $0.40 per-order fee applies on top regardless of category. All of it is calculated on the full amount the buyer pays, item price, shipping, and tax, not the listed price alone. Sellers rated Below Standard pay an extra 6% on every sale (rising to 7% after four consecutive months in that status), and a Very High "item not as described" return rate adds another 5%, so the effective rate can climb well past 20% for a seller with account problems. A Store subscription works the other direction, cutting the final value fee in specific categories enough that high-volume sellers often come out ahead once the monthly cost is factored in.
Mercari skips all of that. The fee is a flat 10% of the item price plus whatever the buyer pays for shipping, with no separate processing charge since Mercari removed that fee for listings created or updated on or after January 6, 2025. On a $50 sale with $8 of buyer-paid shipping, eBay's fees come to $8.29 (13.6% of $58 plus the $0.40 per-order fee), against Mercari's flat $5.80, a gap of roughly $2.50 before either platform's shipping cost is factored in. That gap can move considerably depending on eBay's category rate and the seller's account standing, which is exactly what makes eBay harder to price around. The full math for each platform is in our eBay fees guide and Mercari fees guide, and our full marketplace fees comparison lines these up against every other platform in the series.
For professional resellers
eBay's rate moves by category and account standing. Mercari's doesn't move at all. Oly tracks both automatically as you list, so your margin math is based on what each platform actually charges today.
See how Oly workseBay leaves the shipping decision to the seller at listing: calculated shipping quotes the buyer a live rate based on weight, dimensions, and destination; flat rate sets one price for everyone; free shipping folds the cost into the item price. Whichever option is used, eBay's final value fee applies to the shipping charge too, so the seller effectively pays a percentage on postage they never keep. For cross-border sales, eBay charges a separate 1.65% international fee on top of the final value fee, unless the seller ships through eBay International Shipping, which routes the package to a domestic hub, hands off the international leg and customs to eBay's partners, and waives that 1.65% charge in the process.
Mercari's rate doesn't shift by seller choice the same way. It's flat nationwide, no zone or distance pricing, but it scales with the package's weight and dimensional weight, and the seller decides at listing whether the buyer pays it or it comes out of their own payout as free shipping. There's no equivalent to eBay's international program: Mercari ships only within the 50 states and Washington, DC, so a seller who needs to reach overseas buyers doesn't have that option here at all.
eBay has been running since 1995 and, per its most recent quarterly disclosure, reaches roughly 136 million active buyers worldwide, spanning fixed-price listings and live auctions in categories from electronics and collectibles to auto parts and vintage goods. That scale and the auction format are two things Mercari doesn't offer at all.
Mercari, founded in Japan in 2013 and launched in the US the following year, is smaller and domestic by design, with more than 23 million monthly active users and a public listing on the Tokyo Stock Exchange. Everything sells at a fixed price or through buyer offers; there's no auction format and no path to international buyers through the platform itself. For a seller with niche, high-demand, or collectible inventory, eBay's larger and more global pool of bidders is often the deciding factor, while Mercari's smaller, US-only audience trades reach for a far simpler listing and fee experience.
eBay's visibility tools mirror its complexity: Promoted Listings let sellers pay an ad rate, typically 2 to 10%, charged only when a promoted item sells, Store subscriptions add category-specific fee discounts and larger free-listing allotments, and the auction format itself is a visibility mechanic other platforms don't have. Authenticity Guarantee, eBay's physical authentication program for sneakers, handbags, watches, jewelry, and trading cards, is free to sellers and automatically mandatory once a listing crosses its category's price threshold, there's no opting out of it.
Mercari's tools are narrower and mostly automatic: Smart Pricing gradually lowers a listing toward a seller-set floor price, and Promote gives a manual visibility bump whenever a seller cuts the price by 5% or more. Mercari Authenticate, its own answer to eBay's program, costs sellers $5 per item, is photo-based rather than physical, and is optional below certain category and price thresholds rather than automatic. For anything that falls below either platform's authentication threshold, a seller's own authentication checklist is still the first line of defense against a dispute. Running an ad-driven, auction-capable platform alongside a flat-fee, algorithm-driven one is a different kind of juggling act, and it's usually easier once stock counts and pricing are synced automatically instead of tracked by hand.
eBay tends to win on niche, collectible, or high-demand items where a larger, global bidder pool and the option of an auction format can push the final price up enough to absorb the higher and less predictable fee. It's also the only real option here for a seller who needs to reach buyers outside the US. Mercari fits everyday resale, general merchandise, and sellers who'd rather price simply and skip Store subscriptions, ad rates, and performance-tier penalties entirely.
Plenty of resellers use both for exactly this reason: collectibles and higher-value or hard-to-find pieces go to eBay for the audience and the auction option, while faster-moving general inventory goes to Mercari for the flat, predictable cut. Many add a dedicated fashion platform like Poshmark on top of that split once clothing becomes a large enough share of what they source. Our guide to reselling across multiple platforms covers how to structure that split, and once you're crosslisting beyond just two or three marketplaces, avoiding stockouts when you list everywhere is worth reading before your catalog grows much further.
Two things push it up: certain categories carry a higher base rate than 13.6% to begin with, and seller performance penalties add on top, an extra 6% for a Below Standard rating or 5% for a Very High "item not as described" return rate, both of which can rise further after four consecutive months in that status.
Not through Mercari's own shipping system. Mercari ships to the 50 US states and Washington, DC only, with no option for a seller to ship abroad through the platform. eBay is the option here if reaching buyers outside the US matters for a given item.
It depends on volume and category. eBay's own example shows a seller's final value fee dropping from 13.6% to 9.35% on a Basic Store in one category, enough to outweigh the monthly subscription cost for someone selling several items a month in that category, though the discount and break-even point both vary by category and store tier.
eBay's Authenticity Guarantee is free and mandatory once an eligible listing crosses its category's price threshold, with a physical inspection at an eBay-run facility. Mercari Authenticate is optional in most cases, costs the seller a flat $5, and relies on photos reviewed by a third-party authenticator rather than an in-person check.
Usually, but not universally. A seller in good standing on eBay, in a lower-rate category, or with a Store subscription can close much of the gap with Mercari's flat 10%. The advantage that doesn't disappear is predictability: Mercari's rate is the same regardless of account performance, while eBay's isn't.
eBay's Money Back Guarantee gives buyers up to 30 days from the delivery date to open a case for items that never arrive, arrive damaged, or don't match the listing, regardless of the seller's own stated return policy. Mercari works on a much tighter clock: a 72-hour window tied to the buyer's rating rather than a 30-day case system, so the timeline a seller needs to track isn't close to the same on both platforms.
