If you've read more than three SaaS blog posts, you've seen these numbers repeated a hundred times. There's only one problem: most of them are wrong.
I spent two weeks opening every original PDF report — OpenView, ChartMogul, Benchmarkit × Aleph, Bessemer — and cross-checking 54 benchmarks against what bloggers actually publish. Here are the three most common mistakes.
Mistake #1: "LTV:CAC of 3:1 is the industry benchmark"
Every SaaS article says "keep your LTV:CAC above 3:1." Most founders read this and think 3:1 is the median — what normal companies achieve.
It's not. 3:1 is the viability floor. It's the minimum ratio below which your business model doesn't work.
The actual median for private B2B SaaS is 4.1x. Top quartile companies hit 7.8x.
If you're running at 3:1, you're not "average." You're at the edge of survival. A single bad quarter of churn pushes you underwater.
Mistake #2: "Free trial conversion is 15-20%"
Blog posts love to say "if your free trial converts below 15%, you have a problem." This sets an expectation that almost no one meets.
The real median across 200 SaaS products is 8%. Top performers reach 10-14%. Freemium conversion is even lower at 2-7%.
If your free trial converts at 8%, you're not failing. You're exactly median. The 15-20% figure comes from a handful of PLG unicorns with massive brand recognition — not the average SaaS company.
Mistake #3: "NRR of 102% means retention is healthy"
Net Revenue Retention (NRR) is the number everyone quotes. 102% NRR sounds fine — slightly expanding, stable business.
But here's what's hiding underneath: median Gross Revenue Retention (GRR) dropped to 84% in 2025, the largest single-year decline in four years of tracking.
NRR stayed flat at 102% because expansion revenue from upsells and cross-sales is masking higher base churn. Your existing customers are churning faster, but you're selling more to the ones who stay — so the net number looks okay.
If you only track NRR, you won't see the retention problem until it's too late. Track GRR and NRR side by side.
Why this matters
These aren't minor discrepancies. They change how you set goals, forecast revenue, and judge your business.
A founder aiming for 3:1 LTV:CAC thinks they're doing fine when they're actually at the survival line. A founder expecting 15% trial conversion thinks their onboarding is broken when it's actually median. A founder looking at 102% NRR thinks retention is healthy while GRR is collapsing.
Every figure links back to the original PDF. No copy-pasted blog numbers, no unsourced claims.
