What Is ROAS?
ROAS (Return on Ad Spend) is the ratio of revenue generated to advertising dollars spent. Formula: revenue from ads ÷ cost of ads. A ROAS of 3:1 means every $1 spent on ads generates $3 in revenue. It's the most direct measure of ad campaign profitability.
ROAS (Return on Ad Spend) explained
ROAS tells you whether your ads are making money. It's simpler than ROI (which factors in all costs) and more actionable for campaign-level decisions. Calculating ROAS for SaaS: - Direct ROAS: (monthly revenue from ad-attributed customers) ÷ (ad spend) - LTV-based ROAS: (LTV of ad-attributed customers) ÷ (ad spend) — better for subscription models Example: You spend $1,000 on Meta ads. Those ads generate 20 signups. 5 convert to paid at $50/month. Monthly ROAS = $250 ÷ $1,000 = 0.25:1. Looks bad. But LTV-adjusted ROAS (assuming 12-month retention): $3,000 ÷ $1,000 = 3:1. Looks good. This is why SaaS companies use LTV-adjusted ROAS — monthly revenue from a subscription doesn't reflect the full value of an acquired customer. ROAS benchmarks for SaaS: - Below 1:1 — losing money on every customer (only acceptable if LTV-adjusted ROAS is positive) - 2:1 to 3:1 — healthy for most SaaS with reasonable margins - 4:1+ — very efficient, possibly underinvesting in growth Factors that impact ROAS: - Targeting quality (reaching right people = higher conversion = better ROAS) - Creative quality (better ads = higher CTR = lower CPC = better ROAS) - Landing page conversion (more visitors become signups = better ROAS) - Pricing (higher price = more revenue per customer = better ROAS)

Frequently asked questions
Is ROAS the same as ROI?+
No. ROAS measures ad revenue vs ad spend only. ROI includes all costs (salaries, tools, overhead) against total profit. ROAS is more useful for campaign-level decisions. ROI is better for overall business health assessment.
What ROAS should I target as an early-stage SaaS?+
Use LTV-based ROAS and target 3:1 minimum. For a $50/month product with 10-month retention ($500 LTV), that means spending no more than ~$165 to acquire each customer. Adjust based on your margins and growth stage.
