What is break-even ROAS?
Break-even ROAS is the return on ad spend at which your net profit is exactly zero. It falls straight out of one number — your contribution margin rate, the share of each revenue dollar left after every cost that isn’t advertising:
break-even ROAS = 1 ÷ contribution margin rate
Take a $50 product with $15 COGS and the standard US 6% referral fee. Contribution is $50 − $3 − $15 = $32, or 64% of revenue. Your break-even ROAS is 1 ÷ 0.64 = 1.56×. Anything below that and the campaign is spending more than the orders are worth.
Is 2× ROAS good on TikTok Shop?
There is no answer to this without your margins, which is why the question circulates endlessly in seller groups with contradictory replies. The same 2× is three different outcomes:
- At a 64% contribution margin, break-even is 1.56× — so 2× is genuinely profitable.
- At a 50% contribution margin, break-even is exactly 2× — so 2× earns you nothing at all.
- At a 25% contribution margin, break-even is 4× — so 2× is losing roughly a quarter of revenue on every order.
Add a 20% creator commission to that first product and its contribution rate falls from 64% to 44%, pushing break-even from 1.56× to 2.27×. The campaign didn’t change; the bar did.
ROAS for a target margin
Break-even is survival, not a business. To keep a specific net margin, subtract it from the contribution rate before dividing:
target ROAS = 1 ÷ (contribution margin rate − target net margin)
The same identity read backwards tells you what your current campaigns are really doing: net margin = contribution rate − 1 ÷ ROAS. Enter the ROAS you see in Ads Manager and the calculator converts it into the margin it actually produces.
Note that a target margin above your contribution rate is unreachable at any ROAS — even free traffic wouldn’t get you there, because the gap is in the unit economics, not the ads.
Max cost per order — the number to actually bid against
ROAS is a ratio, and ratios are awkward to act on when you’re setting bids. The dollar version is easier: the most you can pay to acquire one order and still break even is simply your contribution per order — $32 in the example above. Want to keep a 15% net margin on a $50 order instead? Subtract $7.50, leaving $24.50 as your ceiling.
Working out what price supports your ad costs in the first place? Use the break-even price calculator. For profit at a price you have already set, use the TikTok Shop fee calculator. And once orders are settling, MarginReady shows true profit per SKU from your real settled payouts instead of estimates.
