FAQ
Questions CAC Payback Engine owners ask.
- 01
How is the CAC payback period calculated?
The capability calculates annual contribution by multiplying ACV and Gross Margin, then adding any expected expansion revenue. This total is divided by 12 to find the monthly contribution. Finally, the CAC is divided by this monthly figure.
- 02
What are the industry benchmarks used?
The capability uses hardcoded standards: SMB segments target a recovery period between 12 and 18 months, while Enterprise segments target 18 to 24 months.
- 03
Can I analyze the impact of expansion revenue?
Yes, using the evaluate_expansion_impact capability, you can quantify exactly how many months are saved and the percentage reduction in payback time when expansion revenue is included.
