When it comes to ad campaigns, tracking success is crucial. However, the multitude of metrics available can be confusing. Two commonly used metrics, ROI (Return on Investment) and ROAS (Return on Ad Spend), each serve unique purposes. This guide explores the difference between ROI and ROAS, their respective roles, and how to decide which is best for your advertising strategy.
What Is ROI?
Return on Investment (ROI) measures the profit earned compared to the total investment. Unlike ROAS, ROI offers a “big picture” perspective, factoring in all costs involved, not just advertising expenses. It is a vital metric for evaluating whether a project or campaign is financially worthwhile.
How to Calculate ROI
For instance, if you invested $5,000 in an ad campaign that generated $7,000 in profit:
- Positive ROI: Earned more than spent.
- Negative ROI: Incurred a loss.
What Is ROAS?
Return on Ad Spend (ROAS) specifically assesses the revenue generated from ad campaigns relative to the ad spend. This metric is ideal for gauging the direct effectiveness of ads in generating revenue.
How to Calculate ROAS
For example, spending $1,000 on ads that generate $4,000 in revenue gives:
This means every $1 spent on ads returned $4 in revenue.
Key Differences Between ROI and ROAS

Which Metric Should You Use for Ad Campaigns?
Your choice depends on campaign goals, budget, and time frame.
Use ROI When:
- Evaluating Full Profitability: Provides a complete financial view.
- Planning Long-Term Strategies: Measures success over months or quarters.
- Making High-Level Decisions: Guides strategic initiatives like market expansion.
Use ROAS When:
- Testing Ad Effectiveness: Measures creative and targeting impact.
- Managing Limited Budgets: Ensures short-term results for small-scale campaigns.
- Tracking Digital Ads: Works best with real-time insights on platforms like Google or Instagram.
Pros and Cons of ROI and ROAS
| Metric | Pros | Cons |
|---|---|---|
|
ROI |
Comprehensive view of profitability |
Complex due to indirect cost factors |
|
ROAS |

Common Misconceptions About ROI and ROAS
- “ROAS Equals Profitability”
A high ROAS only shows ad revenue efficiency, not total profitability. - “ROI and ROAS Are Interchangeable”
They serve distinct purposes; ROI for overall success, ROAS for ad-specific performance. - “High ROAS Means Campaign Success”
While indicative of good ad performance, ROAS ignores factors like customer lifetime value or sustainability.
Combining ROI and ROAS for Better Insights
Tracking both metrics provides a balanced approach:
- Use ROAS for Real-Time Adjustments: Optimize ongoing campaigns.
- Use ROI for Final Evaluations: Assess long-term profitability after campaigns end.
- Set Different Benchmarks: For example, target a ROAS of 3:1 and ROI of 20% for balanced success metrics.
Conclusion
Both ROI and ROAS are indispensable tools for assessing ad campaigns.
- Use ROAS for immediate insights into ad performance.
- Use ROI for comprehensive profitability analysis.
Tracking both metrics allows you to gain deeper insights into short-term effectiveness and long-term success, empowering you to make well-informed advertising decisions.
