How to use the roas calculator
Calculate return on advertising spend by comparing revenue attributed to ads with the advertising cost. Enter your figures in the fields above and select Calculate. The result updates when you change an input.
Formula
ROAS = Ad-attributed revenue ÷ Advertising spend
Example and interpretation
If an advertising campaign costs $1,000 and is attributed with $5,000 in revenue, its ROAS is 5.0x. This is a revenue efficiency metric, not a profit measure.
