Frequently asked questions
How is CAC computed?
CAC = marketing spend ÷ number of new customers acquired.
How to estimate LTV?
Here: monthly revenue per customer × gross margin × lifespan (in months).
What ratio to aim for?
An LTV:CAC ratio ≥ 3:1 is often considered healthy; below that, acquisition is too expensive.
