Are these the same formulas as /mercari-keep/ and /ebay-keep/?

Yes. This page first-paints only those locked official starting formulas. Mercari: KEEP = sale − 0.10×sale (buyer shipping $0 in first-paint). eBay: KEEP = sale − 0.136×sale − 0.40. No invented FBA tiers or Store discounts.

Does eBay Store or Promoted Listings change the $86.00?

The $86.00 first-paint is the no-Store most-categories row locked on /ebay-keep/. Store category discounts and Promoted Listings are typed extras on the hubs — not invented here. Open /ebay-keep/ and /seller-fees/ebay-promoted-listings for those models.

Is Mercari Buyer Protection subtracted from seller KEEP?

No. Buyer Protection (~3.6%) is buyer-side on /mercari-keep/. Seller first-paint is the 10% selling fee on item (+ buyer-paid shipping base when typed). Do not invent a blended seller take.

Is this affiliated with Mercari or eBay?

Not affiliated with Mercari or eBay. Educational planning only. Shopify Impact links are disclosed affiliates. Confirm live fees in each seller account; platforms can change rates.

When the gap moves (still official only)

eBay Store: category FVF can be lower than 13.6%. We do not invent Store tiers on this page — confirm in Seller Hub and/or type extras on /ebay-keep/.
Mercari shipping base: when buyer shipping is typed into the fee base on /mercari-keep/, 10% applies to item+ship — not invented here.
Low stickers: eBay’s $0.40 flat eats more of a $20 sale. Use the $50 preset above; both formulas stay locked.
Shipping / COGS: not inside these KEEP numbers. Platform take-home ≠ profit after materials.
