How to calculate a TikTok Shop affiliate commission cap

A commission cap answers: after the costs and target profit you already accept, how high can the creator rate go. It is not the official commission table in the seller dashboard.

Align the definitions

Net sales revenue is the settlement figure you can actually confirm, after discounts and refunds you choose to include. The commission base may equal net sales or a different contract base. If they differ, follow the contract.

Worked sample (illustration only)

Sample: net sales 100, product 40, fulfillment 10, platform fee 6, other variable 4, ads 5, fixed creator cost 0, commission base 100, target net margin 15%. Cost total 65, break-even commission 35%, target cap 20%.

Contribution = net sales − costs. Target rate = (revenue × (1 − target margin) − costs) ÷ commission base. Break-even rate = (revenue − costs) ÷ commission base.

Common mistakes

Do not fold slotting fees and samples into the commission percentage. Put fixed fees in the allocated fixed-creator field. Do not treat an unverified “industry average” as an official rule.
