FAQ
What is a good CAC payback period?
Many SaaS teams aim to recover CAC within 12 months, though earlier is better. The right target depends on your margins and how much cash you can tie up while waiting to break even.
Why use gross margin in the payback formula?
Because you earn back CAC out of gross profit, not raw revenue. Multiplying monthly revenue by gross margin gives the true monthly contribution toward recovering CAC.
