Frequently Asked Questions

Customer Acquisition Cost is total acquisition spend divided by new customers acquired in the same period. Paid CAC uses paid media spend divided by paid-attributed customers.

There is no universal target, but shorter payback is usually safer. This calculator treats under 6 months as excellent, 6–12 as healthy, 12–18 as watch, 18–24 as costly, and above 24 months as high risk.

Use blended CAC to understand total acquisition efficiency across the business. Use paid CAC to judge paid channel efficiency. Both are useful because organic, referral and sales costs can distort one number alone.
