Frequently Asked Questions
What is CAC Payback Period?
CAC Payback Period measures the number of months required for a SaaS business to generate enough gross profit from a customer to recover the initial cost of acquiring that customer.
How is CAC Payback Period calculated?
The formula is: CAC Payback Period (Months) = CAC / (Monthly ARPU x Gross Margin %). For example, if CAC is $600, ARPU is $100/mo, and Gross Margin is 80%, Payback = $600 / ($100 x 0.8) = 7.5 Months.

For startup SMB SaaS, a CAC payback period under 12 months is considered healthy. Enterprise SaaS products target CAC payback under 18 months.
