Is 4× ROAS always good?

No. At 50% margin, break-even is about 2×. At 25% margin, you need roughly 4× just to break even. Good ROAS is always relative to margin.

Does conversion rate change break-even ROAS?

No. Conversion rate affects max CPC and volume, but break-even ROAS depends only on margin and value per conversion.

ROAS & Break-even

Break-even ROAS is the minimum return on ad spend where contribution margin equals ad spend — the floor below which campaigns lose money after product costs. This topic cluster covers the formula, margin-based targets, and how to set tROAS in Google Ads.

Quick answer

Break-even ROAS is the minimum return on ad spend where contribution margin equals ad spend — the floor below which campaigns lose money after product costs. Conversion rate does not change break-even ROAS — only margin and value per conversion matter.

Break-even ROAS = value ÷ contribution per conversion

Why break-even ROAS matters

Platform dashboards report revenue ROAS. They do not subtract COGS, shipping, or fulfillment. A campaign at 3× ROAS can still lose money at 40% margin. Break-even ROAS ties your ad efficiency target to economics you control: margin, AOV, and fixed per-order costs.
