What is CAC Payback Period?
CAC Payback Period is a core concept in modern B2B revenue. Here is a clear, accurate definition, why it matters, and how Ardovo handles it.
Short answer
The CAC payback period is the time it takes for the gross profit from a new customer to cover the cost of acquiring them, usually measured in months. A shorter payback means capital is recycled faster into more growth. It is a key efficiency metric, especially for capital-constrained subscription businesses.
Key takeaways
- Months for a customer's gross profit to repay acquisition cost.
- Shorter payback recycles capital into growth faster.
- Common benchmark is under twelve months.
- Critical when growth is funded from cash flow.
Why it matters
Payback period governs how fast a business can grow without running out of cash. A 6-month payback funds far more growth per dollar than an 18-month one.
How Ardovo handles it
Ardovo calculates payback from real CAC, margin, and revenue timing per segment, so you see how fast each channel repays. Rook highlights the segments that recycle cash fastest for prioritized investment.
Frequently asked questions
How is CAC payback period calculated?
Divide customer acquisition cost by the monthly gross profit (or monthly recurring revenue times gross margin) that a new customer generates. The result is the number of months to break even on acquisition.
What is a good CAC payback period?
Under twelve months is a common target for healthy SaaS, and top performers recover CAC in well under a year. Longer paybacks strain cash flow and slow the pace of sustainable growth.
