What is a good LTV to CAC ratio?
A healthy SaaS LTV:CAC ratio is 3:1. Below 2:1 the business is buying revenue at a loss once overhead is counted; above 5:1 usually means the company is underinvesting in growth and leaving market share on the table.
How to read your LTV:CAC ratio
| Ratio | Verdict | Action |
|---|---|---|
| Below 1:1 | Losing money | Fix pricing or churn before spending |
| 1:1 – 2:1 | Unsustainable | Cut low-intent channels |
| 3:1 | Healthy | Scale acquisition |
| 4:1 – 5:1 | Strong | Increase spend deliberately |
| Above 5:1 | Underinvesting | Test more channels |
How to read this table
- With 5 reference points in the "how to read your ltv:cac ratio" table, the fastest way to use this page is to find the closest row, take its verdict, then stress-test it ±30% before you build a plan on it.
Context
The ratio is only as good as the LTV input. Use gross-margin LTV, not revenue LTV, or you will systematically overstate the payoff of every acquisition channel. Blended CAC also hides trouble: split paid from organic, because a great blended ratio can conceal a paid channel losing money on every customer.
What moves this number
Segment
Self-serve, SMB, mid-market, and enterprise SaaS have materially different benchmark ranges. Compare within your segment only.
Contract length and billing terms
Annual prepay changes retention, cash flow, and payback maths against the same monthly price point.
Growth stage
Early-stage numbers are noisy on small denominators; benchmarks stabilise past roughly $1M ARR.
Definition drift
Half of all benchmark disagreements are definitional — whether churn is logo or revenue, gross or net, monthly or annualised.
Methodology
LTV = ARPA × gross margin ÷ monthly churn rate. CAC = fully loaded sales and marketing spend ÷ new customers in the same period. Benchmarks reflect commonly cited 2026 SaaS operating standards.
Assumptions and caveats
- Benchmarks are self-reported and skew toward companies willing to publish good numbers.
- Compare within your segment and stage; cross-segment comparisons mislead.
- This page was last reviewed on 2026-08-12. Ranges are updated as new data lands, so re-check before using them in a contract or a plan.
- Use these numbers as a starting range, not a guarantee — your own historical data always beats a benchmark.
