How TikTok Shop commission affects profit
Seller-funded discounts reduce your sale value. Platform-funded discounts reduce the buyer’s payment but are added back when calculating commission. The tool separates customer payment, platform funding and commission so you can review the cost of a campaign.
Is the 9% rate the same for every seller?
9% is the published standard rate, including applicable fee taxes. Eligible sellers can have reduced rates, including some category and incentive arrangements. Use the confirmed-rate option rather than assuming a reduction applies to every product.
Does commission include VAT?
Yes. The published UK standard commission is inclusive of applicable taxes. The calculator extracts the fee VAT using your invoice rate. It does not add 20% on top of a VAT-inclusive commission.
How are discounts treated?
Original price minus seller and platform discounts gives the item amount paid by the customer. Customer-paid shipping is added, then the platform-funded discount is added back to the commission base. This estimate models a completed sale without refunds.
Why do affiliate fees need a separate base?
The affiliate agreement and settlement determine the relevant base. Shipping and discount treatment can differ from platform commission. Enter the actual affiliate base to avoid assuming both fees use the same amount.
Are shipping and campaign costs automatically estimated?
No. Enter your actual or expected charges. These inputs are effective costs after eligible VAT recovery. Shipping service fees, campaign contributions and advertising can vary by order and programme.
