What is Customer Acquisition Cost (CAC) and how is it analysed in MerchantSpring?

Customer Acquisition Cost (CAC) measures the total cost required to acquire a new customer. This metric is commonly used by ecommerce businesses to evaluate the effectiveness of marketing and advertising investments.

CAC helps businesses understand how much they spend to generate new customers and whether those customers generate enough revenue to justify the acquisition cost.

MerchantSpring allows businesses to analyse CAC by combining advertising performance data with sales and customer insights.

Why CAC Is Important

Understanding Customer Acquisition Cost helps businesses:

• evaluate marketing efficiency
• determine sustainable advertising budgets
• compare acquisition costs across channels
• measure the profitability of marketing campaigns

CAC is often analysed alongside Customer Lifetime Value (LTV) to determine whether customer acquisition strategies are financially sustainable.

How CAC Is Calculated

CAC is typically calculated as:

Total Marketing & Advertising Spend ÷ Number of New Customers Acquired

For example:

CAC = $10,000 ÷ 500 = $20 per customer

Using MerchantSpring for CAC Analysis

MerchantSpring provides the data needed to evaluate CAC by combining:

• advertising spend data
• sales performance data
• customer acquisition metrics

This allows businesses to compare marketing investment against revenue generated.

Notes: 

• CAC should always be evaluated alongside LTV.
• Marketing campaigns with high CAC may still be profitable if customer lifetime value is strong.
• CAC can vary significantly between acquisition channels.
