Auction.co.kr Fee & Profit Calculator
Auction.co.kr per-item profit, margin, and break-even price using category fee 7~13%, Smile Delivery 1~3%, card 2.4%, VAT, and auction vs Buy-It-Now mode.
About this tool
Auction.co.kr Fee & Profit Calculator helps sellers on Auction (eBay Korea) compute per-item net profit, margin %, break-even price, and a 1,000-order sim. Enter list price, COGS, category, payment method, and trade mode (auction / Buy-It-Now), and it deducts category sales commission (7~13%), Smile Delivery 1~3%, card fee 2.4%, and VAT. Auction shares the same eBay Korea platform as Gmarket but adds an auction channel (auto -10% on average winning bid) and Smile Delivery is ~0.5pp cheaper than Gmarket.
