Key fact: Ad ROAS is a vanity metric until platform commission, fulfillment and refunds come out of it — the break-even ROAS and CPA lines above are the only targets that must hold. The default 8% refund rate in the calculator is a placeholder, not a benchmark; use your last 30 days of actual orders in Seller Center.
Attributed sales = orders × AOV (the gross number Ads Manager reports).
Contribution per order = AOV × (1 − refund%) × (1 − commission%) − COGS − other. Commission is modeled as reversed on refunded orders; COGS on a returned unit is assumed sunk (worst case — set your own refund assumption accordingly).
Net ad profit = orders × contribution − ad spend. ROAS = sales ÷ spend. CPA = spend ÷ orders. Ad ROI = net profit ÷ spend.
Break-even ROAS = 1 ÷ [ (1−refund%)(1−commission%) − (COGS + other) ÷ AOV ] — the ROAS at which the campaign earns exactly zero. Break-even CPA = contribution per order — the most you can pay for a conversion.
| Metric | What it tells you |
|---|---|
| ROAS above break-even | Campaign adds profit — scale test budgets in steps |
| ROAS at break-even | Orders grow but profit does not — watch for hidden costs |
| ROAS below break-even | Every incremental order loses money — fix CPAs or margins first |
| CPA vs break-even CPA | Bid/creative target: keep actual CPA under the break-even line |
This is a planning model, not TikTok-published benchmark data — no official ROAS or CPA targets are quoted here. Always reconcile against your own Ads Manager and Seller Center figures.
There is no universal number — "good" is whatever clears your break-even ROAS with margin for error. Compute it above from your own COGS, commission and refund rate instead of copying someone else's target.
GMV Max optimizes toward attributed GMV or orders automatically, so the inputs are the same: what you spent and what it attributed. Paste the campaign's spend and orders and the break-even lines still apply.
Yes. Ad ROAS is a vanity metric until the platform's commission, fulfillment and refunds come out of it — that is exactly what the net ad profit and break-even lines add here.
Your last 30 days of actual orders in Seller Center. Fashion and beauty run high; the default 8% here is only a placeholder, not a benchmark.
