Frequently Asked Questions
What is CAC Payback Period?
CAC Payback Period is the number of months it takes for a company to earn back the Customer Acquisition Cost (CAC) through the gross profit generated by that customer.
What is a good CAC payback period?
For SMB SaaS, 12 months is standard. For enterprise SaaS, 18-24 months is acceptable. Anything under 6 months is exceptional.
Why include gross margin in the calculation?
Revenue isn't profit. If it costs you money to deliver your service (hosting, support), those costs must be subtracted from revenue to see how much real cash is paying back the acquisition cost.
Understanding CAC Payback Period for SaaS
Customer Acquisition Cost (CAC) payback period is one of the most critical capital efficiency metrics. It answers a simple question: How long does your cash stay tied up in a customer before you break even on marketing and sales spend?
Why Months to Recover CAC Matters
If your payback period is 6 months, you can reinvest the same dollar twice in a single year. If your payback period is 24 months, your growth depends heavily on external funding to float cash burn.
