Understanding CAC & LTV
For any modern recurring revenue business or e-commerce platform, two metrics reign supreme: Customer Acquisition Cost (CAC) and Customer Lifetime Value (LTV). Together, they tell the story of a company's marketing efficiency and unit economic health. If CAC exceeds LTV, the business is fundamentally unprofitable at its core; if LTV is significantly higher than CAC, the company has an engine for highly profitable growth.
What is Customer Acquisition Cost (CAC)?
CAC is the total amount spent on marketing campaigns, advertising, sales commissions, and salaries to acquire a single customer. It is calculated by dividing total sales and marketing spend by the number of new customers acquired during that same period.
What is Customer Lifetime Value (LTV)?
LTV measures the total gross margin a customer generates during their lifespan with your company. The basic formula is: LTV = (Average Revenue Per User × Gross Margin %) ÷ Churn Rate. Churn rate represents the rate at which customers cancel or stop buying from you. Decreasing churn is one of the most effective ways to boost LTV.
