How to calculate CAC
Divide all marketing and sales spend by the number of new customers in the same period: CAC = spend ÷ new customers. Spending $10,000 to win 50 customers is a CAC of $200 each. Count everything that goes into acquisition — ad spend, salaries, tools and commissions.
The LTV/CAC ratio
CAC only means something next to LTV (what a customer is worth over their lifetime). The rule of thumb is LTV/CAC ≥ 3: every dollar spent acquiring a customer should return at least three across the relationship. Below that, growth may not pay for itself; far above it, you might be under-investing in acquisition.
