TikTok Shop profit margin: the complete seller calculation guide

For each SKU, begin with the amount the seller keeps after seller-funded discounts. Add customer-paid shipping only when it is part of seller proceeds. Then subtract the costs that scale with an order.

A practical model separates platform fees, creator commission, paid acquisition, product cost, fulfilment, return processing and other per-order costs. This makes the result actionable: you can see which lever is actually reducing margin.

A return rate changes more than revenue. You may lose the sale, keep part of the fulfilment cost, pay reverse logistics and recover only part of the inventory value. Modelling all orders as successful usually overstates profit.

Run a base case with your recent return rate, then test a worse case. If the product becomes unprofitable after a small increase, the offer needs more margin or a tighter returns process before it scales.

Margin shows efficiency, while profit per order shows how much room you have to acquire the next customer. Two products can have the same margin but very different cash contribution because their selling prices differ.

Use monthly profit for planning, margin for comparing products and profit per order for decisions about CPA and creator commission.

A forecast should never be one optimistic line. Compare a decline, stable and growth scenario. The order volume changes, but unit economics must remain the anchor: scaling an unprofitable SKU simply compounds the loss.
