How to calculate customer acquisition cost
Why customer acquisition cost matters for Shopify users
CAC determines whether your growth strategy is economically sustainable. Rising CAC without corresponding increases in customer value erodes profitability and limits scalable growth.
Shopify merchants can segment CAC by marketing channel, campaign, and product to identify the most cost-efficient acquisition paths and reallocate budget accordingly.
Understand and act on customer acquisition cost with KPI Tree
Combine Shopify customer data with marketing spend from your ad platforms in the warehouse. KPI Tree links CAC to LTV and first-order profitability in a unified metric tree.
Assign marketing ownership with RACI clarity and set alerts when CAC exceeds target thresholds by channel, enabling rapid budget reallocation.
