What is a good customer acquisition cost (CAC)?
People search for a good CAC benchmark hoping for a dollar figure, but the honest answer is that CAC is only meaningful relative to what a customer generates. A 500 dollar CAC is terrible if customers churn in two months and great if they stay for years.
The right way to judge CAC is through two ratios: LTV to CAC and CAC payback period. Those relate your acquisition cost to the value and speed of return, which is what actually determines whether growth is healthy.
Short answer
There is no universal good CAC in dollars because it depends on what a customer is worth. A good CAC is one that produces an LTV to CAC ratio of 3 to 1 or better and a payback period under 12 months. Judge CAC against lifetime value and payback, never in isolation.
Key takeaways
- There is no absolute good CAC in dollars; it depends on customer value.
- Aim for an LTV to CAC ratio of at least 3 to 1.
- Target a CAC payback period under 12 months for SaaS, faster for SMB.
- Compare CAC to your own trend and by channel, not to other companies.
The benchmarks that actually matter
For B2B SaaS, the widely cited healthy targets are an LTV to CAC ratio of 3 to 1 and a CAC payback period of 12 months or less. Enterprise deals can justify longer payback because they retain longer; SMB should recover CAC faster because those customers churn sooner.
A ratio far above 3 to 1 (say 6 to 1) is not always good news; it can mean you are underinvesting in growth and leaving the market to competitors.
How Ardovo handles it
Ardovo shows CAC beside LTV to CAC and payback on one screen, so you always see cost in the context that makes it meaningful. Rook flags when CAC drifts out of the healthy band for a segment and points to the channel driving it.
Frequently asked questions
What is a good CAC for SaaS?
Not a fixed dollar amount. A good SaaS CAC yields an LTV to CAC ratio of at least 3 to 1 and recovers within 12 months. Enterprise can run longer payback, SMB should be shorter.
Is a lower CAC always better?
Not necessarily. A very low CAC paired with underinvestment can mean you are growing slower than you could. The goal is efficient growth, not minimal spend. Balance CAC against growth rate and payback.
What is a good LTV to CAC ratio?
Around 3 to 1 is the healthy benchmark. Below 3 suggests you are spending too much to acquire. Above 5 can signal you are underinvesting in acquisition and could grow faster.
