Why high repeat purchase rate changes your break-even ROAS
A store with strong retention can afford a lower first-order ROAS than a business where every customer buys once. That does not change the mathematics of the first order. It changes how much the business is willing to invest to acquire the customer.
First-order break-even stays the same
If contribution before advertising is 40%, the first-order break-even ROAS remains around 250% in the simplified model.
Customer-level break-even can be different
If each new customer is expected to generate substantial repeat contribution, the business may willingly run first-order acquisition below 250% because future orders recover the cost.
Use expected contribution, not revenue
If repeat purchases generate $100 revenue but only $35 contribution, the business has $35 of additional acquisition room, not $100.
Keep targets channel-specific where useful
A channel that acquires better-retaining customers can potentially support a higher CAC than one that attracts discount-driven one-time buyers.
High lifetime value does not eliminate cash-flow constraints. The time required to recover marketing spend still matters. That's the subject covered in CAC payback period for ecommerce. Retention turns ROAS from an order-level metric into a customer-economics discussion.
