What is the formula for Customer Acquisition Cost (CAC)?

The formula for Customer Acquisition Cost (CAC) is a critical metric that businesses use to evaluate the cost-effectiveness of their marketing and sales efforts. The correct approach to calculating CAC involves summing the marketing expenses and sales expenses over a specific period and then dividing that total by the number of new customers acquired during the same period.

This method provides a clear picture of how much a business is spending to attract each new customer, allowing for a better assessment of profitability and budget allocation. By using this formula, businesses can understand their customer acquisition strategies' efficiency and make informed decisions to optimize their marketing and sales activities.

This accurate calculation helps businesses ascertain whether their spending aligns with their revenue growth and can guide strategies for reducing CAC through improved marketing tactics or sales processes. The other options, while related to business metrics, do not specifically reflect the true cost of acquiring new customers in the same comprehensive way that the selected formula does.
