Why TikTok Shop GMV is not profit
By CogsIQ. Published 4 October 2026.
GMV is the first number Seller Center shows you and the one that grows fastest. It measures sales, not what you kept. A shop can double its GMV and lose money doing it, and nothing on the GMV chart will say so.
What GMV measures
Gross merchandise value is the value of the orders customers placed: what they were charged for items and shipping, counted when the order is placed. It is a good measure of demand and a poor measure of a business, for three reasons.
- It is measured before your costs. None of TikTok's fees, the fulfilment charge, the creator's commission or the cost of the goods comes out of it.
- It counts orders that do not stay sold. An order refunded next week was still placed this week.
- It is not your revenue either. When TikTok funds a coupon, the customer pays less but TikTok pays you the difference. GMV shows what the customer paid, so on heavily promoted orders it can sit below what you are actually owed.
So the useful starting point for profit is not GMV but revenue: the item price less the discounts you funded and less refunds.
From GMV to profit, in order
Take costs out in the order money leaves, so each step can be checked against a document:
- Revenue. Item price, less discounts you fund, less refunds. TikTok-funded discounts stay in.
- TikTok's fees. Platform commission and affiliate commission, from each settlement.
- Fulfilment and shipping. The Fulfilled by TikTok fee per order, or your 3PL's handling, and shipping charged to you, including return shipping.
- Cost of goods. The landed cost of the units that shipped: supplier price plus freight, duty and prep.
- Warehouse fees and ads. Storage billed by the warehouse, and the ad spend that drove the sales.
- Samples. Units sent free to creators cost you their landed cost and their fulfilment.
- Operating expenses. Software, contractors and other overheads, for the shop's bottom line.
An example shop
Five months of an example shop, every deduction taken out in turn:
| Sales at item price | $66,380.00 |
|---|---|
| Discounts | −$18,900.00 |
| Fulfilment and shipping | −$16,400.00 |
| Cost of goods, FIFO | −$14,200.00 |
| Platform and affiliate fees | −$7,650.00 |
| Warehouse and ads | −$3,100.00 |
| Refunds and samples | −$1,579.20 |
| Net profit | $4,550.80 |
Of $66,380.00 in sales at item price, the shop kept $4,550.80, under 7 cents of each dollar. The largest deductions are not TikTok's commission but discounts and fulfilment, which are the two a GMV chart is least likely to make you think about.
Why growth can hide a falling margin
The same example shop, month by month:
| Month | Sales | Units | Net margin |
|---|---|---|---|
| March | $8,240.00 | 620 | −13.6% |
| April | $11,480.00 | 890 | +7.3% |
| May | $6,910.00 | 520 | −4.6% |
| June | $18,300.00 | 1,430 | +11.7% |
| July | $21,450.00 | 1,680 | +14.0% |
March brought in sales and gave back 13.6 cents of every dollar. Sales cannot go below zero; margin can, and a sales chart has no way to show it. The usual causes are costs that do not scale with the price: a flat fulfilment fee on a cheap item, a promotion you funded, a freight rate rise on the latest batch, or a creator commission on top of a discount.
Timing: placed, settled and paid
GMV counts an order when it is placed. TikTok settles it later, once its fees are final, and pays it out later still, in a payout that holds some money back in reserve. Profit read on the order date (accrual) says whether the shop is trading well. Profit read on the payout date (cash) says what reached your bank. Both are right, and they will not match in any given week. The settlements guide covers how to tie them together.
What to track instead
- Net profit and margin per SKU, so you know which products pay for the others.
- Margin over time, with an alert when it falls, not only when sales fall.
- Profit per batch, because the same SKU bought at two prices earns two different margins. See FIFO batch costing.
- The fees per order, from your settlements. See TikTok Shop fees.
To test one product quickly, the profit calculator takes a price and its costs and returns profit per unit and margin.
