ROAS Calculator & Guide (2026): Formula, Benchmarks & Break-Even Analysis
Return on Ad Spend (ROAS) measures how much revenue your advertising generates for every dollar (or rupee) spent. It is the primary scaling metric for performance marketers on Google Ads, Meta Ads, and other paid channels.
ROAS formula
ROAS = Revenue from Ads ÷ Ad Spend
Express as ratio (4:1 or 4×) or percentage (400%).

Break-even ROAS
ROAS alone does not tell you if a campaign is profitable — you need gross margin:
Break-even ROAS = 1 ÷ Gross Margin (decimal)
| Gross Margin | Break-even ROAS | Target ROAS (healthy) |
|---|---|---|
| 30% | 3.33× | 5×+ |
| 40% | 2.5× | 4×+ |
| 50% | 2.0× | 3×+ |
| 60% | 1.67× | 2.5×+ |
A campaign with ROAS 3.0 and 60% margin is highly profitable. The same ROAS with 25% margin loses money.
ROAS vs ROI vs MER
| Metric | Formula | Scope |
|---|---|---|
| ROAS | Revenue ÷ Ad Spend | Single channel/campaign |
| ROI | (Profit − Cost) ÷ Cost | All business costs |
| MER | Total Revenue ÷ Total Marketing Spend | All channels blended |
