    Definitions

    Customer Acquisition Cost (CAC)

    The total cost of acquiring a new customer, calculated by dividing total sales and marketing spend by the number of new customers acquired in a given period.

    Blended CAC

    The weighted average CAC across all acquisition channels, including overhead costs like sales team salaries and tools. Gives a holistic view of acquisition efficiency.

    Channel CAC

    The cost per customer for a specific marketing channel, calculated by dividing that channel's spend by the customers it acquired. Excludes shared overhead costs.

    Overhead Costs

    Shared costs that support customer acquisition but aren't tied to a specific channel — such as sales team salaries, CRM tools, and analytics software.

    Overhead per Customer

    The portion of shared overhead costs allocated to each acquired customer. Calculated by dividing total overhead by total customers acquired across all channels.

    Channel Efficiency

    A comparison of CAC across channels to identify which sources deliver customers most cost-effectively. Lower CAC indicates higher efficiency.

    Insights

    Strengths

    • Content Marketing is your most efficient channel at $250.00 per customer.

    Watch Out

    • Blended CAC exceeds $500. Ensure your LTV supports this acquisition cost.

    Recommended Actions

    • Overhead costs represent a large share of CAC. Look for ways to automate or reduce overhead.
