FAQ
What costs should I include?
All sales and marketing spend for the period — ad spend, salaries of marketing/sales staff, tools, and any other cost directly tied to acquiring customers.
How does CAC compare to LTV?
A healthy business generally wants LTV to be several times higher than CAC — a common rule of thumb is an LTV:CAC ratio of at least 3:1.
Should I calculate CAC per channel?
Yes, calculating it separately for each acquisition channel (ads, organic, referral) usually gives more actionable insight than one blended number.
