Why we picked it This is the honest counterweight to the hype in your question. It states plainly that a K-factor above 1 is rare, then backs it with real numbers: consumer internet products doing well sit around 0.15 to 0.25, and even 0.2 is genuinely good. It resets your expectations before you burn months chasing a number almost nobody hits.
K-Factor Benchmarks
From Saxifrage Blog by Michael Taylor ~10 min read
- K-factors above 1 are rare, so treat 0.15 to 0.25 as a solid result and 0.7 as outstanding for most consumer products.
- Even a K-factor of 0.2 pays off, it means one free signup for every five you paid to acquire, which meaningfully lowers your blended cost.
- Benchmarks vary wildly by category (Slack and Facebook are outliers, payments companies sit near zero), so compare yourself to your product type, not the headline case studies.
