What Is ROAS? 


Return on Advertising Spend (ROAS) is a critical metric that helps businesses assess the effectiveness of their advertising campaigns. Simply put, it measures the revenue generated for every dollar spent on advertising. 

ROAS calculation provides valuable insights into the profitability of your advertising efforts and helps you allocate your Google ads budget wisely.

What Is The Average Roas For Google Ads?

The average Return on Ad Spend (ROAS) for Google Ads can vary widely depending on the industry, business model, and advertising goals. ROAS is a metric that measures the revenue generated for every dollar spent on advertising. 

However, many successful e-commerce businesses aim for a ROAS higher than 4:1, often in the range of 5:1 to 10:1 or more. It’s important to note that what constitutes a good ROAS can vary based on factors such as profit margins, business goals, and the industry’s average. 

Some industries with lower profit margins might find success with a lower ROAS, while others with higher margins might aim for a higher ROAS calculation. To determine a target ROAS for your Google Ads campaigns, consider factors such as your business objectives, operating costs, and industry benchmarks.

Additionally, continuously monitor and optimize your campaigns to improve performance and achieve your desired ROAS.

How To Perform ROAS Calculation? 


knowing how to calculate the ROAS (Return on Advertising) formula is easy to understand. It takes your advertising revenue and divides it by the advertising cost. The formula is

ROAS Calculation: Cost of Advertising ÷ Revenue from Advertising

Calculate ROAS: Step by Step

Calculating ROAS involves a straightforward process. Here’s a step-by-step guide to help you calculate ROAS effectively:

Step 1: Determine Revenue from Advertising

Determine how much revenue you generate from your ad spend. This includes sales, leads, or any other desired actions on your website attributed to your advertising campaign.

Step 2: Identify the Cost of Advertising

Sum up all costs associated with your advertising campaign. This includes expenses such as ad spend, creative production, and any other costs directly related to the execution of your ads.

Step 3: Apply the ROAS Formula

Once you have the revenue and cost figures, plug them into the ROAS formula:

ROAS Calculation= Cost of Advertising ÷ Revenue from Advertising

Step 4: Interpret the ROAS Value

A ROAS value greater than 1 indicates a positive return on investment, signifying that the advertising campaign generated more revenue than it cost. For example, a ROAS of 5 means that for every dollar spent on advertising, $5 in revenue was earned.

Conversely, a ROAS of less than 1 suggests that the advertising campaign did not generate enough revenue to cover its costs, indicating a less efficient use of the advertising budget.

To illustrate, if your advertising campaign costs $1,000 and generates $5,000 in revenue, your ROAS would be 5. This ROAS calculation shows that for every dollar spent on advertising, you gained $5 in revenue.

How Is ROAS Calculation Different From ROI Calculation?


Return on Advertising Spend and ROI (Return on Investment) are both financial metrics used to evaluate the performance and effectiveness of investments, but they are applied in different contexts and have distinct calculations.

ROAS (Return on Advertising Spend):

It is used in advertising and marketing specifically to measure the ROAS (return on investment) for every advertising dollar spent.

  • Calculation: The ROAS calculation is the difference between advertising revenue and the cost of an advertising campaign.
  • The formula is

         ROAS=   Revenue from Advertising ÷ Cost of Advertising​

  • Example: If a company spends $1,000 on a Google Ads campaign and generates $5,000 in revenue from that campaign, the ROAS would be 5 ($5,000 / $1,000). 
ROI (Return on Investment):

It is a broader metric used to assess the overall profitability of an investment, considering all costs and returns, not just limited to advertising.

  • Calculation: Calculate ROI by dividing the net profit (or return) from an investment by the initial cost of the investment. 
  • The formula is

          ROI=​   Net Profit  ÷ Cost of Advertising​

  • Example: If a company invests $10,000 in a new marketing strategy and generates $30,000 in additional revenue, with additional costs of $5,000, the net profit is $15,000. The ROI would be 1.5 ($15,000 / $10,000), or 150%.

All in all, while both ROI and ROAS calculations are measures of financial performance, ROAS is specifically tailored to assess the effectiveness of advertising efforts by comparing advertising revenue to advertising costs. 

ROI, on the other hand, is a more general metric used to evaluate the overall profitability of any investment by considering all costs and returns, not just those related to advertising. 


In the dynamic realm of online advertising, understanding and optimizing for Return on Advertising spending is crucial for long-term success. By following the tips outlined in this guide, you can perform better ROAS calculations and track your ROAS effectively on Google Ads. 

Remember, the key to a successful ROAS is a combination of strategic planning, continuous optimization, and leveraging the right tools to stay ahead of the competition.
