What is a good LTV to CAC ratio?
The 3 to 1 LTV to CAC benchmark is the most cited rule in SaaS unit economics. It represents a healthy balance between paying enough to grow and not overpaying for customers.
Like all benchmarks, it assumes honest inputs. A 3 to 1 built on gross-margin LTV and fully loaded CAC is meaningful; a flattering ratio built on revenue LTV and media-only CAC is not.
Short answer
A good LTV to CAC ratio is about 3 to 1, meaning you earn three dollars of lifetime gross profit for every dollar spent acquiring a customer. Below 3 signals acquisition is too expensive; below 1 means you lose money per customer. Above 5 can indicate you are underinvesting in growth.
Key takeaways
- Around 3 to 1 is the healthy target.
- Below 3 means acquisition is too costly.
- Below 1 means you lose money per customer.
- Above 5 can signal underinvestment in growth.
Why 3 to 1 and not higher
Three to one leaves room to reinvest in growth while keeping acquisition profitable. A much higher ratio, say 6 to 1, is not automatically better; it often means you are spending too little on acquisition and ceding the market to competitors who are willing to grow faster.
The ratio must be built on gross-margin LTV and a fully loaded CAC. A suspiciously high number usually hides revenue-based LTV, understated churn, or a CAC that omits salaries.
How Ardovo handles it
Ardovo builds both inputs from one source of truth so the ratio cannot be gamed by mixing definitions. Rook flags when the ratio drifts outside the healthy band and shows whether CAC, churn, or expansion drove the move.
Frequently asked questions
What is a good LTV to CAC ratio?
Around 3 to 1. Below 3 means acquisition is too expensive relative to value; below 1 means you lose money per customer. Above 5 can mean you are underinvesting and could grow faster.
Is a higher LTV to CAC ratio always better?
No. A very high ratio often signals underinvestment in acquisition, leaving growth on the table. The goal is efficient growth near 3 to 1, not maximizing the ratio by spending too little.
Why might my ratio look too high?
Usually because LTV uses revenue instead of gross margin, churn is understated, or CAC omits salaries. Rebuild both inputs honestly; a genuine ratio far above 5 to 1 more often means underinvestment than exceptional economics.
