What is ROAS?
Return on Ad Spend (ROAS) is a marketing metric that measures the revenue generated for every dollar spent on advertising. It’s one of the most important metrics for evaluating the effectiveness of your advertising campaigns and helps you understand which campaigns are profitable and which need optimization.
ROAS Formula
The basic formula for calculating ROAS:
ROAS = Revenue from Ads / Cost of Ads
Divide the revenue generated by your ads by the total cost of those ads
Where:
- Revenue from Ads = Total Revenue - The total revenue generated from your advertising campaign
- Cost of Ads = Ad Spend - The total amount spent on the advertising campaign
How to Calculate ROAS
Follow these steps to calculate your ROAS:
1. Determine Your Revenue from Ads
Calculate the total revenue generated from your advertising campaign. This includes all sales directly attributed to your ads.
Example: If your campaign generated $10,000 in sales
2. Calculate Your Total Ad Spend
Add up all costs associated with your advertising campaign, including ad platform fees, creative costs, and management fees.
Example: If you spent $2,000 on the campaign
3. Apply the ROAS Formula
Divide your revenue by your ad spend to get your ROAS ratio.
Example: ROAS = $10,000 / $2,000 = 5.0 or 5:1
4. Interpret Your Results
A ROAS of 5:1 means you earned $5 for every $1 spent on advertising. Compare this against your target ROAS to evaluate performance.
Example: 5:1 ROAS indicates strong campaign performance
ROAS Calculation Examples
Real-world scenarios to help you understand ROAS:
Example 1: E-commerce Campaign
Scenario: An online store runs a Facebook ad campaign. They spend $5,000 on ads and generate $25,000 in revenue.
Calculation:
- Identify revenue and cost: Revenue = $25,000, Ad Spend = $5,000
- Calculate ROAS: ROAS = $25,000 / $5,000 = 5.0 or 5:1
Conclusion: For every $1 spent on ads, the store earned $5 in revenue. This is a strong ROAS indicating a profitable campaign.
Example 2: SaaS Product Launch
Scenario: A SaaS company spends $10,000 on Google Ads for a product launch and generates $30,000 in first-year subscription revenue.
Calculation:
- Identify revenue and cost: Revenue = $30,000, Ad Spend = $10,000
- Calculate ROAS: ROAS = $30,000 / $10,000 = 3.0 or 3:1
Conclusion: The campaign generated $3 for every $1 spent. While positive, the company should consider lifetime value for a complete picture.
Example 3: Low-Performing Campaign
Scenario: A retail brand spends $8,000 on Instagram ads but only generates $6,000 in revenue.
Calculation:
- Identify revenue and cost: Revenue = $6,000, Ad Spend = $8,000
- Calculate ROAS: ROAS = $6,000 / $8,000 = 0.75 or 0.75:1
Conclusion: The campaign lost money, generating only $0.75 for every $1 spent. This campaign needs immediate optimization or should be paused.
How to Interpret ROAS
Understanding what your ROAS means for your business:
| ROAS Range | Meaning | Recommendation |
|---|---|---|
| < 1:1 | Losing money on ads | Pause campaign and analyze what went wrong. Optimize targeting, creative, or landing pages. |
| 1:1 to 2:1 | Breaking even or slight profit | Campaign is covering costs but needs improvement. Test different strategies to increase ROAS. |
| 2:1 to 4:1 | Moderate profitability | Good performance. Look for opportunities to scale while maintaining ROAS. |
| 4:1 to 8:1 | Strong profitability | Excellent performance. Consider increasing budget to scale successful campaigns. |
| > 8:1 | Exceptional performance | Outstanding results. Analyze what’s working and replicate across other campaigns. |
Key Points to Remember
Important considerations when working with ROAS:
-
🎯 Set Realistic Targets - Target ROAS varies by industry and business model. E-commerce typically aims for 4:1, while SaaS might target 3:1 considering lifetime value.
-
📊 Consider All Costs - Include all advertising costs: platform fees, creative production, agency fees, and management time for accurate ROAS calculation.
-
⏰ Track Over Time - ROAS can fluctuate. Monitor trends over weeks and months rather than making decisions based on daily data.
-
💡 Look Beyond ROAS - ROAS doesn’t account for profit margins or customer lifetime value. Use it alongside other metrics for complete picture.
-
🔄 Optimize Continuously - Test different audiences, creatives, and placements to improve ROAS. Small improvements compound over time.
-
📈 Scale What Works - When you find campaigns with strong ROAS, gradually increase budget while monitoring performance to maintain efficiency.

Frequently Asked Questions
What is a good ROAS?
A good ROAS depends on your industry and profit margins. Generally, 4:1 is considered good for e-commerce, meaning $4 revenue for every $1 spent. However, businesses with higher margins can operate profitably at lower ROAS, while those with thin margins need higher ROAS.
How is ROAS different from ROI?
ROAS measures revenue generated per dollar spent on ads, while ROI (Return on Investment) measures profit. ROAS = Revenue / Ad Spend, whereas ROI = (Revenue - Total Costs) / Total Costs. ROAS is simpler but doesn’t account for profit margins.
Should I include all marketing costs in ROAS?
For accurate ROAS calculation, include all costs directly related to your advertising campaigns: ad platform spend, creative production, agency fees, and management costs. Don’t include general overhead or costs unrelated to the specific campaign.
Can ROAS be negative?
ROAS itself cannot be negative as it’s a ratio of positive numbers. However, a ROAS below 1:1 means you’re losing money (spending more than you’re earning), which is effectively a negative return on your investment.
How often should I check my ROAS?
Monitor ROAS weekly for ongoing campaigns, but make strategic decisions based on monthly trends. Daily fluctuations are normal. Allow at least 2-4 weeks of data before making major changes to give campaigns time to optimize.
What’s the difference between ROAS and ACOS?
ACOS (Advertising Cost of Sale) is the inverse of ROAS, expressed as a percentage. ACOS = (Ad Spend / Revenue) × 100. For example, a ROAS of 5:1 equals an ACOS of 20%. Amazon sellers commonly use ACOS, while other platforms prefer ROAS.
