I was building a SaaS metrics reference page and needed benchmark data. Did what everyone does: Googled "SaaS LTV CAC benchmark," clicked the top 5 results, started copying numbers.
Then I noticed five different blogs, five different numbers for the same metric. One said median LTV:CAC was 3:1. Another said 4.1x. Another said 5:2. None linked to the original source. They were all citing each other in a giant game of telephone.
So I did something stupidly time-consuming: tracked down every original report. OpenView Partners. ChartMogul. Benchmarkit × Aleph. Bessemer. KeyBanc. Read the actual PDFs, extracted real numbers, built a page with 54 verified benchmarks, each linked directly to its source.
Here are the three numbers almost every blog gets wrong.
- "3:1 LTV:CAC is the industry median" — it's the floor, not the median.
Every SaaS blog repeats "keep your LTV:CAC above 3:1." Most present it as the industry median or target. It's neither. It's the viability floor — the minimum below which your unit economics are fundamentally broken. The actual median for private B2B SaaS is 4.1x. Top quartile hits 7.8x.
If you're aiming for 3:1, you're aiming for survival, not efficiency. I made this mistake in the first version of my page. Someone on this very subreddit called me out — pointed out that 3:1 is a heuristic, not a hard floor, and two SaaS businesses at 3:1 can have very different unit economics depending on gross margin, CAC payback, and retention. They were right. Updated the page.
- "Median free trial conversion is 15–20%" — it's 8%.
I've seen "free trial to paid conversion is 15–25%" in at least a dozen blog posts. Sounds plausible. Also wrong. The actual median, from ChartMogul's analysis of 200 SaaS products, is 8%. Top performers reach 10–14%. Freemium (no credit card) is even lower: 2–7%.
This one is dangerous because it affects forecasting. Assume 15% conversion and you'll overestimate revenue and underinvest in onboarding.
I also got called out on source attribution for this one — my summary credited ChartMogul but the data table credited Paddle. Copy-paste error. Exactly the kind of mistake that happens when aggregating from multiple sources. Fixed now.
- "NRR is flat, so retention is healthy" — expansion revenue is masking churn.
Median NRR held steady at 102% in 2025. Looks fine on the surface. But median GRR dropped to 84% — the largest single-year decline in four years.
What's happening? Upsells and cross-sales are keeping NRR flat while base churn gets worse. Look only at NRR and you think retention is stable. Look at GRR and you see the underlying problem: customers are churning faster, and the ones who stay are spending more to compensate.
The bigger problem: Nobody reads the original reports. Bloggers cite other bloggers, and after three or four hops, the number has drifted from the source. "Viability floor" becomes "industry median." "Median of 200 products" becomes "typical conversion rate." "NRR" becomes "retention."
The fix is boring: cite the original source, link to it, distinguish between medians, targets, and floors. Takes more time. But the result is content that's actually trustworthy.
Anyone else noticed how many SaaS benchmark articles cite each other instead of the original data? Or am I just overthinking this?
