What this measures
An ad budget should follow from a goal and an efficiency target, not the other way around. If you know the revenue you want and the ROAS you can realistically hit, the required spend falls out of simple division.
Pairing the budget with your gross margin shows whether the plan actually profits. A revenue goal that needs more ad spend than your gross profit can cover is a goal that loses money.
The formula
Required ad spend = Revenue goal ÷ Target ROAS. Ad profit = (Revenue goal × Gross margin) − Required ad spend. Daily budget = Required ad spend ÷ Days.
Worked example
To hit $50,000 at a 4× ROAS you need $12,500 in ad spend ($417/day over 30 days). At a 60% margin, gross profit is $30,000, so ad profit after spend is $17,500.
