Enter your buy cost and expected sale price. Kickflip applies Mercari's 10% selling fee and your shipping to show what you actually take home and what margin the flip earns.
Fee estimates use the primary tier rate from each platform's public schedule. Tiered pricing, promotion rates, and buyer-fee ranges vary — always confirm current rates with the platform before listing.
Mercari keeps its seller side deliberately simple — one percentage, no separate processing charge:
| Category / tier | Selling fee | Payment processing | Buyer-side fee |
|---|---|---|---|
| All CategoriesFlat 10% seller fee; $0 seller payment processing fee | 10.00% | $0.00 | 3.6% Buyer Protection fee |
Rates change. Confirm against Mercari's current published fee schedule before you commit to a purchase.
Retail arbitrage is buying an item in one place and reselling it where the same item sells for more. A flat 10% seller fee makes Mercari attractive as the selling side of that trade, particularly for lower-priced items where eBay's per-order fee takes a bigger proportional bite. It is also a common buying source: items get listed there quickly and cheaply by people clearing out closets rather than by professional resellers.
Shipping is usually what decides a Mercari flip. On a $20 item, a $9 label is the difference between a healthy margin and a loss, so put your real label cost into the shipping field rather than guessing.
Comparing Mercari against another marketplace before you buy? Use the full retail arbitrage calculator to set a different buying platform and see both sides.
Mercari charges sellers a flat 10% selling fee on the sale, with no separate seller payment processing fee. Buyers pay a separate Buyer Protection fee of about 3.6%, which comes out of the buyer's total rather than your payout.
No. Unlike most marketplaces, Mercari's seller side is a single 10% fee with $0 in seller payment processing, which makes the math simpler than eBay's category-by-category schedule.
It depends on how you list. You can offer free shipping and absorb the label cost, or pass it to the buyer. Both change your margin, so the calculator has separate fields for shipping you pay and shipping the buyer pays.
Mercari's flat 10% is one of the lower seller fees among the mainstream resale apps, which leaves more room on lower-priced items than a 13.6% plus per-order fee structure. Whether a specific flip works still depends on your buy cost, shipping, and what the item actually sells for — run the numbers above before you buy.
