How this calculates
CAC = total acquisition spend divided by new customers acquired in the same period. The LTV/CAC ratio tells you whether your economics work at scale. A ratio below 1 means you lose money acquiring each customer. Between 1 and 3 means you have a sustainability problem. 3-5x is healthy for most SaaS. Above 5x is exceptional but can signal underinvestment in growth.
Paid CAC too high to scale?
Organic CAC is typically 60–80% lower than paid.
The free paid-to-organic gap analysis shows your blended CAC across channels and identifies which paid keywords are candidates for organic replacement. No fabricated projections — built on your real GSC and Google Ads data.
