How to interpret ROAS
ROAS (Return on Ad Spend) measures how effectively your advertising budget generates revenue. It's calculated by dividing total ad revenue by the cost of that campaign:
ROAS = Total Revenue ÷ Total Ad Spend
This metric is a practical way to evaluate the performance of a specific campaign—whether it's Google Ads, Facebook Ads, or other channels—and helps guide budget allocation and ecommerce strategy. While ROAS shouldn't be the sole indicator of business health, it's an effective tool to identify which campaigns are performing well and which need improvement.


What counts as a “good” ROAS?
There's no universal benchmark, as a “good” ROAS depends on:
- Your profit margins
- Industry standards
- Average cost per click
- Average order value
Many businesses aim for a 4:1 ROAS (4X), but the average across ecommerce is closer to 2X. Startups often require higher ROAS to cover costs and grow, while established businesses may succeed with lower ROAS. The key is to measure your ROAS in context and against competitors in your niche.
Going beyond ROAS
ROAS only considers ad spend versus revenue, but other costs like production, shipping, and staffing also impact profitability. To get a complete picture of your marketing efficiency, track ROAS alongside other metrics.

CAC (Customer Acquisition Cost)
Total spend on acquiring customers divided by the number of customers acquired. Compare this to your average order value and contribution margin to understand real profitability.
MER (Media Efficiency Ratio)
Total revenue divided by total marketing spend over a period. Use MER to see how efficiently your marketing budget generates revenue overall.
