ROAS
Return on Ad Spend
The revenue generated for every dollar spent on advertising. Calculated as (Revenue ÷ Ad Spend) × 100. A ROAS of 400% means $4 earned for every $1 spent — a key metric for evaluating paid channel profitability.
How ROAS works in practice
ROAS is a campaign-level efficiency metric; CAC and LTV are the business-level metrics that determine whether a given ROAS is actually profitable. A campaign showing 800% ROAS may still lose money if gross margin is 20% and fulfilment costs are high — always triangulate ROAS with margin and payback period before scaling spend. Target ROAS bidding in Google Ads instructs the algorithm to set bids to achieve a specific revenue-to-spend ratio, but requires accurate revenue conversion tracking to function correctly. For subscription businesses, ROAS should be calculated on predicted LTV rather than first-order revenue to avoid undervaluing high-retention customer cohorts.
