Frequently Asked Questions (FAQ)

Q: What is Cost Per Acquisition (CPA)?

A: Cost Per Acquisition (CPA) is a marketing metric that measures the total cost of acquiring a new customer. It includes all marketing and sales expenses divided by the number of customers acquired during a specific time period. CPA helps businesses understand their customer acquisition efficiency and marketing ROI.

Q: How is CPA calculated?

A: CPA is calculated using the formula: CPA = Total Marketing Costs ÷ Number of Customers Acquired. This includes all advertising expenses, marketing campaigns, sales team costs, and other customer acquisition expenses divided by the number of new customers gained.

Q: What's the difference between CPA and CPL?

A: CPA (Cost Per Acquisition) measures the cost to acquire a paying customer, while CPL (Cost Per Lead) measures the cost to generate a marketing lead. CPL is an earlier stage metric that doesn't account for conversion rates from lead to customer. CPA provides a more complete picture of customer acquisition efficiency.

Q: How can I lower my CPA?

A: To lower your CPA, focus on improving targeting to reach more qualified prospects, optimize marketing campaigns for better conversion rates, streamline the sales process, improve lead quality, and consider referral or content marketing strategies that have lower acquisition costs.

Q: What is a good CPA?

A: A good CPA varies by industry and business model. Generally, a lower CPA is better, but it should be compared to customer lifetime value (LTV). A good rule of thumb is that CPA should be less than 1/3 of LTV to ensure profitability. For example, if your average customer is worth $300 in their lifetime, your CPA should ideally be under $100.
