TikTok Ads ROAS formula
ROAS: Ad revenue ÷ Ad spend
Gross profit (after platform fees): Revenue × (1 − 6% referral fee) − Product cost − Other per-order costs
Gross margin: Gross profit ÷ Revenue
Break-even ROAS: 1 ÷ Gross margin
Assumptions:
- US TikTok Shop flat 6% referral fee (5% for select jewelry) — payment processing already included
- "Other costs" should include shipping and any affiliate/creator commission running alongside the ad campaign
- Break-even ROAS assumes a single-purchase customer — repeat purchases lower the effective break-even over time

Frequently Asked Questions
What is ROAS and how is it calculated for TikTok Ads?
ROAS (Return on Ad Spend) = Ad revenue ÷ Ad spend. If a $200 TikTok Ads campaign generates $700 in TikTok Shop sales, ROAS = $700 / $200 = 3.5×. Unlike raw revenue, ROAS tells you efficiency — a 3.5× ROAS means every $1 spent on ads returned $3.50 in sales, before accounting for product cost or platform fees.
What ROAS do I need to break even on TikTok Shop ads?
Break-even ROAS = 1 ÷ gross margin after platform fees. Example: $30 sale, 6% referral fee (payment processing included), $14 product cost. Gross profit = $30 × 0.94 − $14 = $14.20, gross margin = 47%. Break-even ROAS = 1 / 0.47 = 2.13×. Any ROAS below 2.13× loses money once ad spend is counted.
What is a good ROAS for TikTok Shop campaigns?
It depends entirely on margin. Low-margin products (20–30% gross margin, e.g. electronics) need 3.3–5× ROAS just to break even. High-margin products (50–60%, e.g. beauty or apparel) can be profitable at 1.7–2×. A commonly cited target is 2.5–4× ROAS, but always compare against your specific break-even ROAS, not a generic benchmark.
Does TikTok Shop's referral fee change my break-even ROAS?
Yes — the 6% referral fee (5% for select jewelry) comes out of revenue before you calculate margin, so it raises your break-even ROAS slightly versus a platform with no fee. On a $14.20 gross-profit example above, removing the 6% fee would drop break-even ROAS from 2.13× to about 2.00×. It's a small but real difference worth including rather than estimating with revenue alone.
What's a common mistake when calculating TikTok Ads ROAS?
Using revenue-only ROAS as a profitability signal. A campaign can show 4× ROAS and still lose money if product cost and platform fees eat more than 75% of revenue. Always calculate your break-even ROAS first (from margin), then judge campaign ROAS against that number — not against an industry-wide "good ROAS" figure.
How does TikTok Ads ROAS compare to Shopify or Facebook Ads ROAS?
The ROAS formula itself is identical across platforms (Revenue ÷ Ad spend), but break-even ROAS differs based on each platform's fee structure. TikTok Shop's flat 6% referral fee (all-inclusive) tends to produce a similar or slightly lower break-even ROAS than Shopify (2.9% + $0.30 processing, plus your own traffic costs) at typical order values, since Shopify sellers also fund 100% of acquisition outside the platform.
