The OfferUp vs Mercari fee comparison is a good reminder that headline rates rarely settle a decision. Two platforms at 12.9% differ by fifty cents on a shipped sale — inside the noise of what either will realize on price. What actually differs is the sale model: OfferUp is local-first with a free in-person path, Mercari is postal-first with prepaid labels and a national audience.
If you are choosing across more than these two, the OfferUp vs Facebook Marketplace comparison covers the other big local option, and Mercari vs eBay covers the shipped end. For bulky local items, price the alternative honestly with the shipping cost per unit calculator before assuming posting is viable.
Frequently asked questions
Is OfferUp or Mercari cheaper?
For a shipped sale, Mercari, at every price — its flat 10% undercuts OfferUp's 12.9%, and OfferUp's $1.99 minimum makes cheap items worse still. The gap is $1.45 on a $50 sale and $2.90 at $100. For a local pickup OfferUp charges nothing at all and wins outright, by the full 10% Mercari would have taken.
Does OfferUp really charge no fee for local sales?
For a straightforward in-person cash sale, yes — the 12.9% service fee applies to shipped orders handled through OfferUp's payment system. Set the service fee field to 0 to model that. Optional promotions and shipping labels are separate costs, and buyer-protection terms only apply to shipped orders.
Didn't these two used to charge the same rate?
They did. Mercari previously charged 10% selling plus 2.9% + $0.50 processing, which came to 12.9% + $0.50 — the same headline percentage as OfferUp, leaving the two exactly fifty cents apart. Mercari then dropped the seller-side processing fee and moved to a flat 10% on the buyer-paid total, and buyers pay a protection fee instead. That single change is what turned a coin-flip into a clear win.
Which should I use for a bulky item?
OfferUp, almost always. Furniture, appliances and exercise equipment cost more to ship than they are worth, and OfferUp is built around local pickup where that cost disappears along with the fee. Mercari is the better home for anything small enough to post cheaply.
