What is customer acquisition cost?

Customer Acquisition Cost (CAC) is a critical metric for businesses to determine growth projections and company value, though calculating it involves various complexities. The basic formula for CAC involves dividing the total costs associated with acquiring customers, such as sales and marketing expenses, by the number of customers acquired in a specific period. However, accurately calculating CAC requires considering additional expenses, such as overhead, equipment, and salaries of employees involved in customer acquisition. Missteps in these calculations can affect funding, goal setting, and budget allocations. The definition of a "customer" varies, especially in business models with both paying and non-paying (freemium) users, necessitating separate calculations for different customer categories. The CAC is often compared with Customer Lifetime Value (CLTV), using the LTV:CAC ratio to assess profitability, where a successful business typically has a lower CAC relative to CLTV. Reducing CAC is essential for profitability, prompting businesses to optimize their sales cycles and marketing strategies.
