Paid Ads ROI Calculator FAQ
ROAS (Return on Ad Spend) is total revenue generated divided by total ad spend. A 4x ROAS means you earn $4 in revenue for every $1 spent on ads.
For SaaS companies, a 3–5x ROAS is generally healthy. However, this depends on your margins and LTV — a lower ROAS can be acceptable if customer lifetime value is high.
ROAS measures revenue relative to ad spend (Revenue / Spend). ROI measures profit relative to investment ((Revenue - Spend) / Spend × 100%). A 4x ROAS equals a 300% ROI.
