What Is Return on Ad Spend (ROAS)?
Revenue generated for every dollar spent on advertising.
Return on Ad Spend (ROAS) measures the revenue generated per dollar of advertising spend. The formula is simple: revenue attributed to ads divided by total ad spend. A ROAS of 5:1 means every dollar spent on ads generated five dollars in revenue.
ROAS is a channel-level efficiency metric. Unlike ROI, which accounts for all costs (team salaries, tools, creative production), ROAS only looks at the direct relationship between ad dollars in and revenue out. This makes it useful for comparing channels and optimizing campaigns but insufficient for measuring overall marketing profitability.
For B2B demand gen, ROAS is harder to calculate than in e-commerce because the conversion path is longer. A LinkedIn ad clicked in January may not result in a closed deal until August. You need closed-loop attribution connecting ad clicks to CRM opportunities and revenue to calculate ROAS accurately.
Target ROAS varies by business model. SaaS companies with high lifetime value can tolerate lower initial ROAS because the customer pays over years. A 2:1 ROAS on a customer with a 5-year LTV is actually quite profitable. Companies selling one-time products need higher immediate ROAS to be sustainable.
Frequently Asked Questions
What is a good ROAS for B2B?
Most B2B companies target 3:1 to 5:1 ROAS, but this depends on deal size and lifetime value. If your average deal is $200K with a 3-year retention, even 1.5:1 ROAS may be acceptable. Context matters more than benchmarks.
How is ROAS different from ROI?
ROAS measures revenue per ad dollar only. ROI includes all costs: salaries, tools, creative, overhead. ROAS is a campaign metric; ROI is a business metric. A campaign can have a positive ROAS but negative ROI if overhead costs are high.
