What This Calculator Does
This ROAS calculator helps marketers, media buyers, and business owners measure the return on ad spend for any paid advertising campaign. It calculates your ROAS ratio, net profit after cost of goods sold, cost per conversion, effective margin, and break-even ROAS. Whether you are running Google Ads, Meta Ads, TikTok campaigns, or any other paid channel, this tool gives you a clear picture of campaign profitability using 2026 industry benchmarks.
The Formula
ROAS is expressed as a ratio. A ROAS of 4:1 means you earned $4 for every $1 spent on advertising. To determine true profitability, subtract your cost of goods sold (COGS) from revenue before comparing against ad spend. The break-even ROAS is the minimum ROAS needed to cover product costs, calculated as Revenue / (Revenue - COGS). Any ROAS above that threshold generates profit.
Step-by-Step Example
Enter ad spend
Input your total advertising spend for the campaign period. For example, $5,000 spent on Google Search Ads in one month.
Enter revenue generated
Enter the total revenue directly attributable to the campaign. For example, $20,000 in tracked sales.
Enter cost of goods sold
Add product or service costs (COGS) of $8,000 to calculate true profit, not just top-line revenue.
Review results
ROAS = $20,000 / $5,000 = 4.0x. Net profit = $20,000 - $8,000 - $5,000 = $7,000. Break-even ROAS = 1.67x. Your campaign is profitable.
Real-World Use Cases
Ecommerce Campaign Optimization
Compare ROAS across Google Shopping, Meta, and TikTok campaigns to allocate budget toward the highest-performing channels.
Agency Client Reporting
Provide clients with clear ROAS metrics that demonstrate the value of their ad spend and justify budget increases.
Budget Planning
Use break-even ROAS to set minimum performance thresholds before scaling ad spend on new campaigns or channels.
Common Mistakes to Avoid
Measuring ROAS based on revenue alone without accounting for COGS. A 3x ROAS on a product with 80% COGS means you are losing money.
Comparing ROAS across channels without normalizing for attribution windows. Google Ads and Meta Ads use different attribution models.
Setting a universal ROAS target across all products. High-margin products can be profitable at a lower ROAS than low-margin products.
Ignoring the difference between blended ROAS and channel-specific ROAS. Blended ROAS includes all revenue, not just ad-attributed revenue.
Not factoring in customer lifetime value. A 1.5x ROAS campaign may be profitable if repeat purchase rates are high.
