FAQ
Why can break-even ROAS change over time?
Fee mix, discounts, shipping costs, and product margin changes all shift the margin available to cover ad spend.
Should I include retention in break-even ROAS?
Only if your repeat purchase behavior is stable and measured. Otherwise, use a conservative zero-retention assumption.
Can I run below break-even ROAS?
Sometimes for intentional acquisition campaigns, but only with clear payback tracking and limited budget exposure.
