FAQ

Common questions

What does break even ROAS mean?

+

The ROAS at which ad spend exactly equals the gross profit it brings in. At 40% margin that is 2.5, so every dollar of spend has to return 2.50 in revenue to avoid losing money.

Why gross margin and not revenue?

+

Revenue includes the cost of the product itself. A 4.0 ROAS on a 20% margin product still loses money.

Does this account for repeat purchases?

+

No, it works on the first order. If customers reliably buy again, you can accept a lower first order ROAS and use the CAC LTV Ratio Calculator to check the lifetime numbers.
