How to Calculate ROAS in Google Ads

Unlock the power of Return on Ad Spend (ROAS) in Google Ads. Learn step-by-step how to measure and optimize your ad campaigns for maximum profitability.

In the world of digital advertising, Return on Ad Spend (ROAS) stands out as a crucial metric that goes beyond the success of your investment, as measured by ROI. Instead, ROAS specifically gauges the effectiveness of your digital ad campaign. Simply put, ROAS is a marketing metric that measures the gross revenue generated for every dollar spent on advertising. To optimize your ecommerce business's marketing strategies, monitoring and understanding ROAS in Google Ads is crucial.

Step 1: Grasping the Concept of ROAS

Begin by understanding that ROAS is the gross revenue generated for every dollar spent on advertising. This metric helps you identify the top-performing ads and guides you on optimizing your advertisements for better performance.

Step 2: Accessing Your Google Ads Account

To calculate ROAS, log in to your Google Ads account with the necessary permissions to access the required data.

Step 3: Selecting the Correct Campaign

Within your Google Ads account, click on the name of the specific campaign you want to analyze.

Step 4: Viewing the "Conversions" Column

Once inside the campaign, locate the "Conversions" column among other metrics such as "Clicks," "Impressions," and "Cost."

Step 5: Calculating the Conversion Value

Determine the Conversion Value, which represents the total revenue generated from your ads. The type of conversion being tracked will influence this value. Ensure you understand the total value of conversions to accurately compute ROAS.

Step 6: Noting Your Ad Spend Value

Identify the amount spent on ads by checking the "Cost" column on your Google Ads dashboard.

Step 7: Computing the ROAS

Calculate ROAS by dividing the total Conversion Value by the total Ad Spend. Multiply the result by 100 to express it as a percentage. This final percentage is your ROAS.


ROAS is a pivotal metric for evaluating the effectiveness of your Google ad campaigns. It provides insights into how well your ad spend generates profits and guides your future marketing strategies. Remember not to view ROAS in isolation but as part of a comprehensive set of metrics indicating your ad performance. Always adjust your Google Ads strategies based on ROAS and other relevant metrics to maximize effectiveness and increase profitability.
