The V3 workbook uses five VAT-inclusive base rates: micro 1.947%, small business 1 2.563%, small business 2 2.728%, small business 3 3.003%, and standard 3.63%. The selling rate is 1.001% with seller marketing or 3.003% without. Shopping Connect adds 7.7% when enabled, otherwise 0%. You can edit the rates.
Each fee is truncated to whole KRW before calculating total cost and profit. Free shipping includes the full seller-paid delivery cost. Paid shipping includes only the base fee on shipping collected from the buyer, excluding its difference from actual delivery costs, as in the workbook.
