What Is a Good LTV:CAC Ratio? (Benchmarks)
A good LTV:CAC ratio is 3:1 to 5:1 for B2B SaaS and around 3:1 for consumer apps. Below 3:1 means you're not earning enough from each customer to cover acquisition sustainably. Above 5:1 often means you're underinvesting in growth: you could afford to acquire more aggressively.
A healthy LTV:CAC ratio for B2B SaaS is 3:1 to 5:1, per Bessemer State of the Cloud and OpenView SaaS Benchmarks. Consumer apps run lower, around 3:1. Below 2:1 is structurally risky: you barely earn back what a customer costs to acquire. Above 5:1 sounds great, but it often means you are underinvesting in growth. The ratio is meaningless until you read it next to your CAC payback period.
What LTV:CAC measures
LTV:CAC is the ratio between a customer’s lifetime value and the cost to acquire that customer. LTV is the total gross profit you expect to earn from a customer. CAC is your fully loaded sales and marketing spend divided by the number of new customers won.
LTV:CAC = Lifetime Value ÷ Customer Acquisition Cost
Say a customer pays you €100/month and stays 30 months on average. Your gross margin is 80%. Their LTV is €100 × 30 × 0.80 = €2,400. Winning one customer costs you €600 in blended sales and marketing. Your ratio is €2,400 ÷ €600 = 4:1.
LTV here means gross-margin lifetime value, not raw revenue. Divide top-line revenue by CAC and the ratio flatters you by however generous your margins are.
The benchmark: B2B SaaS vs Consumer
B2B and consumer products follow different growth mechanics, so the benchmark splits.
| Profile | Healthy LTV:CAC | What the edges mean |
|---|---|---|
| B2B SaaS / B2B tech | 3:1 to 5:1 | ~3:1 is the minimum healthy baseline. Above 5:1 often signals under-investment in growth. Below 2:1 is structurally risky. |
| Consumer apps | ~3:1 | Consumer growth is faster but less durable. The same logic applies (too low burns cash, too high signals constrained scale), but read it more loosely than the B2B range. |

Contracts, switching costs and expansion revenue mean one customer can pay back many times over. So a B2B business can tolerate a higher ratio and a slower payback.
Consumer customers churn faster. That caps how high LTV can go, so a consumer business reads its ratio more loosely. A consumer business at 3:1 is in roughly the same health as a B2B business at 4:1.
How to read the number (where “good” gets complicated)
1. A “great” ratio above 5:1 is often a warning sign. It usually means you are too cautious. Your acquisition channels still have headroom, and you choose not to spend into them.
The healthy ranges top out at 5:1 (B2B) and 4:1 (consumer) because a growing business should push CAC up toward the efficient frontier. If your ratio is sky-high and your growth is slow, treat the ratio as a diagnosis rather than a trophy.
2. The ratio is blind to time. LTV:CAC tells you whether a customer pays back, never when. Two businesses both sit at 4:1. One recovers its CAC in 6 months, the other takes 24. The first reinvests and compounds. The second finances every new customer for two years before breaking even.
So read LTV:CAC and the CAC payback period together. Healthy payback runs 6 to 12 months for SMB/self-serve B2B and 12 to 24 months for enterprise sales (sources: OpenView, KeyBanc). Consumer payback is faster, but the tool does not source a precise range, so don’t quote a hard number.
3. LTV is a forecast. CAC is something you spent. LTV is a prediction of how long customers stay and how much they pay, and that prediction rests on retention. If your retention assumption is wrong, your LTV is wrong, and so is the whole ratio.
Compute LTV off a few flattering months of data, and you extrapolate a lifetime that never arrives. Before you trust your ratio, pressure-test the curve underneath it. See retention rate benchmarks for what durable retention looks like by profile.
When the three disagree, trust retention first, then payback, then the ratio.
How to improve your LTV:CAC
There are two levers: raise LTV or lower CAC.
Raise LTV (usually the better lever).
- Improve retention. Longer-lived customers lift LTV mechanically, and the effect compounds. If your B2B Day-90 cohort retention is under 2.5%, you sit below the published B2B median (Amplitude). Fix that before you touch CAC. The retention rate benchmarks give the sourced B2B Day-90 range, 2.5% to 15.6%.
- Grow revenue per customer through expansion: seats, usage, upsell to higher tiers. In B2B, net expansion can make a customer worth multiples of their starting contract.
- Protect gross margin. LTV should be margin-adjusted, so a few points of margin flow straight through to the ratio.
Lower CAC (real, but with a ceiling).
- Sharpen targeting so spend lands on customers who convert and stay.
- Build acquisition that isn’t pure paid spend: content, referrals, product-led loops. B2B virality is weak: a K-factor of 0.1 to 0.3 is normal (sources: Reforge, Andrew Chen).
Cutting CAC by simply spending less raises your ratio and shrinks your business at the same time. Aim for the best ratio you can sustain while still growing as fast as the market allows.
See where your numbers land
Enter your numbers in the free benchmark tool and it charts your LTV:CAC, CAC payback, retention curve and K-factor against B2B and consumer reference ranges. It takes six minutes. You see the ratio and whether the retention and payback underneath it hold up. Benchmarks are context, not targets.
If you are still finding out whether people want the thing, start with what product-market fit actually is. Come back to LTV:CAC once retention is real. For the full B2B picture, the B2B SaaS growth benchmarks for 2026 put every one of these numbers in one place.
LTV:CAC ranges come from Bessemer State of the Cloud, OpenView SaaS Benchmarks and a16z. CAC payback comes from KeyBanc SaaS Survey. K-factor comes from Reforge and Andrew Chen. Cohort retention comes from Amplitude, Adjust and AppsFlyer. These are the same sources behind the scilla.studio benchmark tool. Use them as directional references, not absolute targets.
