CAC is the total amount you spend to acquire a new customer. This includes marketing campaigns, sales team costs, tools, and any related expenses required to convert a lead into a paying customer.
LTV is the total revenue you expect to generate from a customer over the entire duration of their relationship with your business. It reflects retention, pricing, and repeat purchases..
A ratio of 3:1 is widely considered healthy. This means you earn three times the cost of acquiring a customer, indicating sustainable growth.
It helps you understand whether your growth is profitable. If CAC is higher than LTV, your business may lose money on each customer.
You can improve LTV by increasing retention, improving customer experience, offering upgrades, and building long-term relationships with customers.
