Core formula
The math behind the result.
Break-even ROAS = revenue per order ÷ contribution before advertisingQuestions
Useful before you decide.
What does break-even ROAS mean?
It is the lowest return on ad spend at which the order makes zero profit after the costs entered.
Why is target ROAS higher?
A campaign must spend less than the break-even ad allowance to leave room for your desired profit.
How should I estimate returns reserve?
Use recent channel-specific return and refund data where possible. A rough guess can materially overstate profitability.
