# Customer Acquisition Cost > **Quick answer**: Customer Acquisition Cost (CAC) measures the total expense a business incurs to acquire one new customer, including marketing spend, sales salaries, and software costs. Companies calculate CAC by dividing total acquisition expenses by the number of new customers gained in a period. This metric helps businesses evaluate channel efficiency and optimize budget allocation.

During this period, they acquire 50 new customers. Their CAC would be $340 per customer ($17,000 ÷ 50). By analyzing this metric, they discover their Facebook ads generate customers at $250 each, while Google Ads cost $500 per customer. This insight allows them to reallocate budget toward the more cost-effective channel, potentially reducing their overall CAC to $300 in the following quarter and improving profitability while maintaining growth targets. ## You should also read: [Customer Buying Signals](/glossary/customer-buying-signalsx)[Customer Centricity](/glossary/customer-centricityx)[Customer Churn Rate](/glossary/customer-churn-ratex)[Customer Data Analysis](/glossary/customer-data-analysisx)[Customer Data Management](/glossary/customer-data-managementx)[Customer Data Platform](/glossary/customer-data-platformx)[Customer Engagement](/glossary/customer-engagementx) ## Why teams choose Derrick.
