A ROAS of 3.0x to 4.0x ($3-$4 revenue per $1 spend) is typically considered sustainable across eCommerce and digital products.

What does an LTV:CAC below 3.0 mean?

An LTV:CAC under 3.0 indicates low customer profitability or high acquisition burn, suggesting a need for conversion rate or retention improvements.

Should organic costs be included in CAC?

Blended CAC includes all marketing salaries and organic tools, while Paid CAC strictly measures ad media spend.
