ROAS measures revenue generated for every dollar spent on advertising, serving as the primary efficiency metric for paid user acquisition.
Return on Ad Spend (ROAS) is the ratio of revenue attributable to advertising to the cost of that advertising. A ROAS of 3x means every $1 spent on ads generated $3 in revenue. It is the most important top-level efficiency metric for paid UA because it directly connects creative and targeting decisions to business outcomes.
ROAS is measured at multiple granularities: campaign ROAS, ad set ROAS, and creative ROAS. Creative-level ROAS is the most actionable for creative teams, it shows which specific ads are generating the highest revenue-per-dollar-spent, enabling data-driven decisions about what to scale and what to cut.
ROAS benchmarks vary significantly by business model. E-commerce businesses often target 3–5x ROAS. Subscription apps targeting LTV-based returns may run at 0.8–1.2x D7 ROAS knowing that revenue accrues over months. Mobile games measure D1, D7, and D30 ROAS milestones against LTV curves.
ROAS is the ultimate creative scorecard. Two creatives driving the same install volume at the same CPI can have dramatically different ROAS if they attract users with different engagement and monetization patterns. A creative that attracts high-LTV users may be worth running at higher CPI precisely because its ROAS is superior. ROAS-based creative evaluation is more sophisticated, and more accurate, than CPI-only analysis.
Example
“A subscription app spends $50,000 on a Meta campaign and generates $185,000 in subscription revenue attributable to those ads, a 3.7x ROAS. Breaking this down by creative, the top video achieves 5.2x ROAS while the weakest static ad achieves only 1.8x.”

LTV is the total net revenue a user is expected to generate over the full course of their relationship with your app, used to determine how much you can profitably spend to acquire them.
