What is LTV:CAC Ratio?
LTV:CAC Ratio 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 LTV to CAC ratio compares the lifetime value of a customer to the cost of acquiring them. A ratio of 3 to 1 means each customer is worth three times what it cost to win them, a common benchmark for a healthy SaaS business. Too low means unprofitable growth; too high may mean underinvesting.
Key takeaways
- Customer lifetime value divided by acquisition cost.
- A 3 to 1 ratio is the common health benchmark.
- Below 3 to 1 signals unprofitable or fragile growth.
- Far above 3 to 1 can mean you are underinvesting in growth.
Why it matters
This single ratio captures whether growth creates or destroys value. It keeps acquisition spend anchored to what customers are actually worth over their lifetime.
How Ardovo handles it
Ardovo computes LTV and CAC from real revenue and spend data and shows the ratio by segment, so you know which segments to scale and which to fix. Rook flags channels whose ratio is trending below target.
Frequently asked questions
What is a good LTV to CAC ratio?
Around 3 to 1 is the widely cited benchmark for healthy SaaS unit economics. Below that suggests acquisition is too expensive; well above it may mean you could grow faster by spending more.
Why can a ratio be too high?
A very high ratio can mean you are underinvesting in sales and marketing and leaving growth on the table. It signals room to spend more aggressively while still acquiring customers profitably.
