ROAS = revenue from ads ÷ ad spend. A 4× ROAS means you earn $4 for every $1 spent. Breakeven ROAS depends on your profit margin — at 40% margin, breakeven is 2.5×.
Guide
What ROAS is profitable for your business?
ROAS alone does not tell you whether a campaign is making money. Breakeven ROAS is 1 ÷ profit margin — a 40% margin needs 2.5× ROAS just to break even on ad spend. Use this calculator to compare your result against that threshold before you scale spend or pause a channel.
Analytics platforms like Semrush report on competitor ad spend and keyword overlap, but your team still has to pull revenue attribution from GA4 or your ad platform to know if campaigns are profitable. Pair this calculator with clean UTM tagging so revenue maps to the right source and medium.
When you want ROAS tracked and acted on automatically, mktcrew's ads agents sync performance from Google Ads, Meta, and LinkedIn and surface evidence-backed recommendations for your approval — start a 15-day free trial with no credit card.

FAQ
ROAS calculator FAQ
What is ROAS?
ROAS (return on ad spend) measures how much revenue you generate for every dollar spent on advertising. A 4× ROAS means you earn $4 in revenue for every $1 in ad spend.
How do you calculate ROAS?
ROAS = revenue from ads ÷ ad spend. For example, $4,000 in revenue from $1,000 in ad spend gives a ROAS of 4× (or 400%).
What is a good ROAS?
A 4:1 ratio (400%) is a widely cited benchmark, meaning $4 in revenue for every $1 spent. What counts as good depends on your profit margins, industry, and campaign goals — a low-margin business needs a higher ROAS to be profitable than a high-margin one.
What is the difference between ROAS and ROI?
ROAS measures gross revenue per ad dollar (revenue ÷ ad spend). ROI factors in all costs — ad spend plus cost of goods sold and overhead — to measure net profit. ROAS is simpler and focuses only on the ad spend itself.
What ROAS is profitable?
Breakeven ROAS is 1 ÷ profit margin. If your profit margin is 40%, breakeven ROAS is 2.5× — you need to earn $2.50 in revenue for every $1 in ad spend just to break even. Anything above breakeven is profitable.
