Customer Acquisition Cost Effectiveness Ratio measures how efficiently a business spends money to acquire new customers. It compares the cost of acquiring customers to the value those customers bring, helping companies understand if their marketing and sales efforts are financially worthwhile.
Synonyms: Customer Acquisition Efficiency Ratio, Customer Acquisition Cost Efficiency Ratio, CAC Effectiveness Ratio, Customer Acquisition ROI Ratio

This ratio is calculated by dividing the total cost spent on acquiring customers by the revenue generated from those customers. A lower ratio means the company is spending less to gain each customer relative to the revenue they bring, indicating better cost effectiveness.
Tracking this ratio helps businesses identify if their customer acquisition strategies are profitable. If the cost to acquire customers is too high compared to the revenue they generate, the business may need to adjust its marketing tactics or sales approach.
Improving this ratio can involve reducing marketing expenses, targeting more qualified leads, or increasing the average revenue per customer. Businesses often analyze this ratio alongside other metrics like Customer Acquisition Cost (CAC) and Customer Lifetime Value (CLV) to make informed decisions.
