什么是CAC回收期？

The CAC payback period is the number of months it takes to recover the cost of acquiring a customer from the gross profit that customer generates.

例如，考虑一家公司 那 获取一位客户 for two thousand dollars, and the MRR of that customer is one hundred dollars at an 80% gross margin: 2,000 ÷ (100 × 0.8) = 25 months. Dividing by revenue alone would give 20 months. You can run your own numbers in our CAC投资回收期计算器.
