Customer Acquisition Cost (CAC)
CAC is the total cost of acquiring one new paying customer — paid ads + content + sales rep time + tooling, divided by customers acquired in the same period. Pair with LTV for unit-economics health.
More detail
Industry benchmark: LTV:CAC ratio of 3:1 is healthy SaaS, 5:1 is great, <1:1 is broken. For Aiprosol's Starter plan ($997/mo with 24-month median retention): LTV ~$23,928. Healthy CAC ceiling: $8,000. For Enterprise ($7,997/mo): LTV ~$192K, CAC ceiling ~$64K. These ceilings inform what's reasonable to spend on customer acquisition.
