The ROAS Formula
ROAS (Return on Ad Spend) measures the revenue earned for every dollar spent on advertising. A ROAS of 4 means you earn $4 for every $1 spent on ads.
What is ROAS?
ROAS stands for Return on Ad Spend. It's a marketing metric that measures the effectiveness of your advertising campaigns by comparing the revenue generated to the amount spent on ads. Unlike ROI which measures overall profit, ROAS specifically focuses on ad performance and helps marketers understand which campaigns are driving the most revenue per dollar invested.
How to Calculate ROAS: Step-by-Step
Calculating ROAS is straightforward. Follow these four simple steps to measure your advertising performance:
Collect Your Ad Spend Data
Gather the total cost of your advertising campaigns from all platforms (Google Ads, Facebook, etc.).
Calculate Your Ad Revenue
Sum up all revenue directly generated from your advertising campaigns. Use proper attribution.
Apply the ROAS Formula
Divide your total revenue by your total ad spend: ROAS = Revenue ÷ Ad Spend.
Interpret Your Results
A ROAS of 4x means you earned $4 for every $1 spent. Compare against industry benchmarks.

What is a Good ROAS?
A 'good' ROAS varies by industry, business model, and profit margins. As a general rule, a ROAS of 4:1 (400%) is considered strong for most businesses. However, high-margin products can be profitable at lower ROAS, while low-margin products need higher ROAS to be viable. Here are industry benchmarks:
| Industry | Average ROAS | Good ROAS |
|---|---|---|
| E-commerce | 2.87x | 4.0x+ |
| Fashion | 4.12x | 5.0x+ |
| Electronics | 3.50x | 4.5x+ |
| SaaS | 5.00x | 7.0x+ |
ROAS vs ROI: What's the Difference?
ROAS and ROI are both important metrics, but they measure different things. ROAS measures gross revenue relative to ad spend, while ROI measures net profit relative to total investment. ROAS is specific to advertising performance, while ROI gives a broader view of overall profitability including all costs.
| Aspect | ROAS | ROI |
|---|---|---|
| Formula | Revenue ÷ Ad Spend | (Profit - Cost) ÷ Cost |
| Measures | Gross revenue | Net profit |
| Best For | Campaign performance | Overall profitability |
| Result | Ratio (e.g., 4x) | Percentage (e.g., 300%) |
Understanding Break-even ROAS
Break-even ROAS is the minimum ROAS needed to cover your costs and avoid losing money. It's calculated by dividing 1 by your profit margin. For example, if your profit margin is 30% (0.30), your break-even ROAS is 1 ÷ 0.30 = 3.33x. Any ROAS above this means you're making profit.
How to Improve Your ROAS
If your ROAS isn't meeting targets, here are proven strategies to improve it:
- Optimize targeting - Focus on high-intent audiences
- Improve ad creatives - Test different formats and messages
- Refine landing pages - Increase conversion rates
