What is CAC Payback Period?

CAC Payback Period measures how long it takes to recoup the costs spent to acquire a customer. A shorter payback period indicates more efficient acquisition and faster return on investment. Typically ranges from 3-12 months for healthy SaaS companies. Payback period directly impacts cash flow and is critical for assessing acquisition sustainability. Lower payback = faster cash recovery and more capital available for growth.
