The method / Questions answered
Read both sides of the score.
ROAS measures revenue, not profit. Use the same attribution window for both amounts.
How is ROAS calculated?
Return on ad spend (ROAS) = revenue attributed to ads ÷ ad spend. A 4× ROAS means $4 in revenue for each $1 spent on ads. It does not mean $4 in profit.
What does an example look like?
Fictional example: $1,000 ad spend and $4,000 revenue give a 4× ROAS. If direct job costs are $2,000, there is $1,000 left after those costs and ads, before regular overheads.
Which revenue should I count?
Use revenue attributed to these ads with the same reporting window and a consistent definition, such as booked or collected revenue. Do not mix all business revenue with only one campaign’s spend.
Google explains conversion values and the conversion value/cost column. The value you choose to track affects how you interpret that ratio; this calculator uses revenue.
What if ad spend is zero?
ROAS is undefined when ad spend is zero, even if revenue is also zero. With optional direct costs, the tool can still show what remains after costs and ads. That amount may be negative.
