How much TikTok Shop affiliate commission can my margin support?
Calculate contribution before and after a seller-supplied creator commission, then solve a conservative arithmetic rate ceiling that preserves the seller's own per-sale contribution floor.
Start with a complete one-sale cost stack
For each product, record selling price, landed cost, fulfillment cost, other variable cost, the supplied commission-fee basis and rate, the supplied transaction-fee basis, rate, and flat amount, the affiliate commission basis, planned affiliate rate, and the seller's minimum contribution. Use one currency and seller-owned aliases only. Do not upload creator, shopper, order, message, or contact data; a margin preflight needs none of it.
Calculate platform fees before creator commission
Recompute the platform commission and transaction fee from their separate seller-supplied bases and terms, rounding each once to cents. Subtract landed cost, fulfillment cost, other variable cost, and those two platform fees from selling price. The result is contribution before affiliate commission. If that amount is already at or below the seller floor, creator commission did not create the original lack of headroom.
Apply the planned affiliate rate and preserve the floor
Multiply the supplied affiliate basis by the planned percentage and subtract the rounded commission from pre-affiliate contribution. Compare post-affiliate contribution with the seller floor and keep both signed headroom and positive-only shortfall. Separate zero or negative contribution, no pre-affiliate floor headroom, planned-rate shortfall, and within-floor rows; those states require different review questions.
Solve a conservative rate ceiling, not a recommendation
Maximum commission dollars for the floor equal the greater of zero and contribution before affiliate minus the seller floor. Divide that amount by the supplied affiliate basis, cap the result at one hundred percent, and round down so the displayed percentage cannot overstate the arithmetic ceiling. This value is not a recommended creator rate and predicts no clicks, orders, attribution, conversion, or incremental sales.
Verify program terms and omitted costs before setting anything
Review the current product price, fee bases, platform terms, creator arrangement, samples, discounts, refunds, shipping subsidies, taxes, and costs omitted from the model. Re-run the scenario when any input changes. This preflight does not establish TikTok Shop or Affiliate Center eligibility. Friday reads no account, contacts no creator, sets no commission, creates no campaign, spends nothing, changes no product or price, and publishes no listing.
