How to use this

Keep GMV Max and Spark Ads campaigns above 2.75x ROAS to avoid losing money, and aim for 4.69x to hit a 15% net margin. Equivalently, never pay more than $10.89 in ad spend per order.

Why break-even ROAS matters on TikTok Shop

TikTok Shop sellers pay a referral fee (around 6% for most US categories), payment processing, and often a creator commission of 10–30% before shipping and refunds. Those costs shrink the margin left to pay for ads, so a ROAS that looks healthy in Ads Manager can still lose money. Your break-even ROAS is the line every GMV Max and Spark Ads campaign must stay above.

The formula

Break-even ROAS = 1 ÷ contribution margin, where contribution margin = (price − COGS − shipping − percentage fees) ÷ price. For a target net margin, use 1 ÷ (contribution margin − target margin).

How to lower your break-even ROAS

  1. Raise average order value with bundles so fixed shipping costs are spread across more revenue.
  2. Negotiate lower product or packaging costs once volume is proven.
  3. Use tiered affiliate commissions instead of one high rate for every creator.
  4. Improve listings and reviews to cut refunds — see our TikTok Shop SEO guide.
  5. Test new creatives weekly; better click-through lowers cost per order. Our ads management team can run this for you.

FAQ

Frequently asked questions

What is break-even ROAS?

Break-even ROAS is the return on ad spend at which your ads neither make nor lose money. Below it, every ad-driven order costs you more than it earns; above it, ads add profit. It depends on your margin after product cost, TikTok fees, affiliate commission, shipping and refunds.

How do you calculate break-even ROAS?

Divide 1 by your contribution margin. Contribution margin is (selling price − product cost − shipping − percentage fees such as referral, processing, affiliate and refunds) ÷ selling price. A 40% contribution margin gives a break-even ROAS of 1 ÷ 0.40 = 2.5x.

What is a good ROAS for TikTok Shop ads?

There is no single good number — it must be above your own break-even ROAS. Products with high margins can scale profitably at 2–3x, while thin-margin products may need 5x or more. Use the target margin field to see the ROAS you need to keep a specific profit.

What is the difference between break-even ROAS and target ROAS?

Break-even ROAS is the point of zero profit. Target ROAS is the higher number you need to keep a chosen net margin after ad spend. When you set a ROAS goal for GMV Max or other campaigns, use your target ROAS, not break-even.

What is max cost per order (max CPA)?

It is the most you can spend on ads to win one order before that order loses money — your profit per order before ads. If your ads cost more than this per order, reduce bids, improve creatives or raise your price.
