Shop Fee Calculator: The TikTok Shop Margin Reality Check

Field notes

The calculator combines marketplace region, category, order value, shipping, discounts, creator commission, fulfillment, advertising, product cost, and return rate before reporting payout, margin, ROI, and break-even price. Its displayed US example uses a $40 order, 12% affiliate commission, $3.58 single-unit FBT, $12 product cost, and an 8% return rate, producing a stated $19.32 break-even price. Regional rate pages, a change log, and methodology links provide a visible record of how the estimates are framed.
