Working note
Make the estimate useful.
Break-even ROAS is a guardrail, not a target. It shows how much revenue each advertising dollar must produce before the order's contribution reaches zero. A business still needs room above that line for overhead, returns, and profit.
Questions from the desk
Break-even ROAS Calculator FAQ
Is a higher break-even ROAS better?
No. A higher break-even requirement means there is less contribution available for advertising and the campaign has less room to operate.
Should customer lifetime value be included?
Only when repeat purchase behavior is measured reliably. For a conservative first-order view, exclude future revenue.
What is the difference between ROAS and ROI?
ROAS compares attributed revenue with ad spend. ROI compares profit with the investment required to earn it.
