Why is CAC/CPA Important?
- Measure Marketing Efficiency
CAC/CPA helps you evaluate the efficiency of your marketing and sales activities. A lower CAC indicates that you’re acquiring customers cost-effectively. - Set Sustainable Growth Goals
Understanding CAC/CPA allows you to ensure that your acquisition costs are balanced against the revenue generated by each customer. - Optimise Budget Allocation
By tracking CAC/CPA across different campaigns or channels, you can identify the most cost-effective methods of acquiring customers and focus your budget accordingly. - Improve Profit Margins
High CACs can erode profit margins, but by reducing acquisition costs, you can improve the overall profitability of your business.
How to Use CAC/CPA for Decision-Making
CAC is most effective when used alongside other metrics like Customer Lifetime Value (CLV). By comparing CAC with CLV, you can assess the long-term profitability of your customers. For example:
- If CLV > CAC: Your business is likely profitable.
- If CLV < CAC: You may need to revisit your marketing and sales strategies to reduce costs or increase revenue per customer.
