What Is Customer Acquisition Cost and Why Does It Matter?
Customer Acquisition Cost (CAC) is the total cost of acquiring a new customer for your business. It includes all spending on marketing, advertising, sales, and any other activities required to convert someone into a paying customer.
For Shopify store owners, CAC is one of the most critical metrics because it directly determines whether your business can grow profitably. If you spend $100 to acquire a customer who only spends $50, you’re losing money on every sale.
According to Shopify’s research, the average ecommerce CAC ranges from $50 to $130, with the overall average around $70. However, CAC varies dramatically by industry—beauty brands might see $30 CAC while electronics can exceed $150.
Understanding your customer acquisition cost helps you make smarter decisions about advertising budgets, channel allocation, and overall marketing strategy.
