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.
