| Strategy & Analytics | How do you calculate the Customer Acquisition Cost (CAC) to LTV ratio, and what’s the ideal value? | CAC = Total Campaign Cost / Number of Acquired Customers; LTV = Avg. Order Value × Purchase Frequency × Customer Lifespan. Ideal CAC:LTV is 1:3 or higher. A ratio less than 1:1 means you’re losing money. |
