Break-Even ROAS Calculator
How much can you spend on ads per sale before you start losing money? Enter your numbers — get your break-even ROAS instantly.
How it works
Break-even ROAS = Selling price ÷ Gross margin per unit.
Gross margin per unit is what is left after COGS, TikTok commission, affiliate commission and other per-unit costs — but before ad spend. If your actual ROAS is higher than break-even ROAS, your ads are profitable. Example: $29.99 price with $12 COGS, 8% commission and 10% affiliate leaves about $9.60 margin, so break-even ROAS ≈ 3.1x — every $1 of ads must bring $3.10 of revenue.
Frequently asked questions
What is break-even ROAS?
The ROAS (return on ad spend) at which your ads neither make nor lose money. Above it, ads are profitable; below it, they lose money.
What is a good ROAS for TikTok Shop?
It depends on your margin. With thin margins you may need 4x or more; with healthy margins 2.5-3x can work. This calculator tells you your exact number.
How do affiliate commissions affect ROAS?
Affiliate payouts come out of the same margin as ads, so a 20% affiliate rate raises your break-even ROAS sharply. Enter your real affiliate rate above.
