Updated benchmarks for buyer-side SaaS due diligence. Compare any acquisition target against industry medians for monthly churn, annual churn, and logo retention across 14 SaaS sectors. Download CSV (CC BY 4.0) ↓
If you're buying a SaaS business, the first question isn't "how much revenue do they have?" — it's "how much of that revenue will still be here in 12 months?" Industry-relative churn benchmarks are the fastest way to separate a healthy asset from a ticking decay bomb.
TL;DR: Monthly churn varies dramatically by sector: enterprise SaaS averages 1-2%, SMB SaaS runs 5-8%, and consumer apps can exceed 10%. Before evaluating a target, look up its sector median — anything meaningfully above the benchmark warrants deeper investigation. ChurnLens benchmarks every uploaded CSV against 14 industry verticals automatically.
Monthly churn (logo churn) measures the percentage of customers who cancel in a given month. These are the medians we've observed across thousands of buyer-side CSV uploads processed through ChurnLens.

|---|---|---|---|

| Mid-Market SaaS ($100–$1K MRR) | 3–5% | 31–46% | Moderate |
| Enterprise SaaS ($1K+ MRR) | 1–2% | 11–22% | Good |

When you're evaluating a SaaS acquisition, the seller's reported churn number is almost always optimistic. Common inflations include:
ChurnLens normalizes for all three tricks. Upload a CSV of the target's subscription history and get a buyer-side churn report that strips out the spin.

ChurnLens computes both metrics from your CSV and flags any divergence that would mislead a buyer.

Want to automate this analysis? Get the 23-point churn audit checklist →Hidden churn is revenue decay that headline metrics conceal: customers on annual plans who have already stopped using the product, paid accounts sitting inactive, or revenue concentrated in a few logos about to leave. A SaaS business can show flat MRR while its real retention is collapsing. ChurnLens surfaces these signals before you buy, so you price the deal on true revenue quality.
ChurnLens analyzes five dimensions: revenue concentration, logo retention, annual-plan churn risk, inactive paid accounts, and MRR decline patterns. Each is weighted into a single 0-100 revenue-quality score benchmarked against comparable SaaS businesses. The score tells an acquirer whether reported MRR is durable or propped up by customers who are one renewal away from leaving, all before the deal closes.
Purchase price is usually a multiple of recurring revenue, so overstated retention directly inflates what you pay. A business with 20% hidden annual-plan churn is worth far less than its MRR implies. Buyers who skip churn diligence discover the decay only after closing, when it is too late to renegotiate. ChurnLens gives that visibility during the evaluation window instead.
Watch for revenue concentrated in a handful of accounts, a widening gap between signups and active users, annual contracts that never renew, and MRR that grows only through discounting. Each pattern signals fragile revenue. ChurnLens automatically flags these red flags from uploaded revenue data and ranks them by how much they threaten the durability of the recurring revenue base.
