Understanding Your ROAS Calculation
Return on Ad Spend (ROAS) is a critical marketing metric that measures the amount of revenue your business earns for each dollar it spends on advertising. Unlike ROI, which considers overall profitability, ROAS focuses specifically on the gross revenue generated from ad campaigns.
How This Calculator Works
Our algorithm uses four key inputs to derive your campaign performance:
Total Ad Spend: Your total budget spent on the campaign.
CPC (Cost Per Click): The average amount you pay for each click. This determines total traffic volume.
Conversion Rate: The percentage of clicks that result in a sale.
AOV (Average Order Value): The average dollar amount spent each time a customer places an order.
The Formula
The core formula used in this tool is: ROAS = Total Revenue / Total Ad Spend.
We calculate Total Revenue by first determining traffic (Spend / CPC), then applying the conversion rate to find total sales, and finally multiplying by the Average Order Value.
What is a "Good" ROAS?
While benchmarks vary by industry, a common target is a 4:1 ratio ($4 revenue for every $1 spent). If your ROAS is below 2:1, you may be losing money once other operating costs are factored in. Use this calculator to test scenarios—such as increasing your conversion rate or lowering CPC—to see how they impact your bottom line.
