Strong return
ROAS = revenue from ads ÷ ad spend. Your break-even ROAS depends on margin, so a "good" number varies by business.
What is ROAS?
Return on ad spend (ROAS) is the revenue generated for every dollar spent on advertising. It's the core efficiency metric for any paid-marketing campaign.
ROAS = revenue from ads ÷ ad spend
How to read your result
- A ROAS of 4 means $4 of revenue per $1 spent.
- The break-even ROAS depends on your margin, not a fixed number.
- ROAS is revenue-based; ROI is profit-based — don't confuse them.
- Segment by campaign to cut the losers and scale the winners.
Frequently asked questions
What is a good ROAS?
It depends on your margins. A common rule of thumb is 4:1, but a low-margin business needs a higher ROAS to be profitable and a high-margin one can thrive on less.
