About ChurnCost.com
An independent reference for what SaaS churn actually costs in May 2026: direct MRR loss, wasted customer acquisition spend, and destroyed lifetime value, with 2026 benchmarks by segment and vertical. No vendor relationships, no affiliate links, no quote forms.
Why this site exists
SaaS churn cost lives across at least three independent layers (direct MRR loss, wasted CAC, destroyed LTV and expansion revenue) and the typical operator analysis counts only the first one. That single-layer shortcut understates churn cost by roughly 50 to 70 percent, which is why retention investments routinely fail an internal business case that would otherwise approve cleanly.
The three-layer model has been argued in the SaaS-finance literature for years (David Skok at For Entrepreneurs, ProfitWell, Recurly, ChartMogul), but most published calculators implement only Layer 1. This site implements all three and shows the formula on every page so anyone can re-run the math against their own assumptions.
The other gap is segment-aware benchmarks. A 5 percent monthly churn rate is catastrophic for enterprise SaaS and adequate for SMB SaaS, but most published benchmarks blur the bands together. The pages on this site segment by ACV (enterprise, mid-market, SMB, B2C), by vertical (SaaS, e-commerce subscription, telecom), and by funding stage so the comparison is apples-to-apples.
Who builds this
ChurnCost.com is built and maintained by Oliver Wakefield-Smith at Digital Signet, an independent reference-content studio. Background spans SaaS finance modelling, product analytics, and AI-system design.
ChurnCost.com is part of a portfolio of SaaS-finance reference properties that also covers saasmetricscalculator.com, saasvaluationmultiple.com, and retentioncost.com. ChurnCost owns the three-layer-cost angle; RetentionCost owns the cohort-decay angle; SaaSValuationMultiple owns the exit-multiple angle; SaaSMetricsCalculator owns the formula-reference angle.
Editorial position
This is a reference site, not a customer success platform reseller, not a managed services lead-generation property, and not a CS-vendor funnel. The /tools comparison orders ChurnZero, Gainsight, Totango, and Vitally by published pricing tier and target-buyer fit, not by any commercial relationship. Where a vendor publishes a price band, the band is shown; where a vendor only offers custom quotes the page flags "custom" rather than invent a point estimate.
Where a benchmark is contested between sources (the median NRR figure between Bessemer, OpenView, and KeyBanc; the involuntary-churn percentage between Recurly and ProfitWell; the expansion-revenue contribution between ChartMogul and Battery Ventures), both ends of the range are shown with the source named.
What this site covers
Editorial principles
Every benchmark, percentile, and segment band on this site traces back to a named primary source: Bessemer State of the Cloud, OpenView SaaS Benchmarks, ChartMogul SaaS Subscription Index, Recurly Subscription Economy reports, ProfitWell research, KeyBanc / Pacific Crest SaaS Survey, SaaS Capital churn-and-valuation research, or public 10-K filings. Where a number is derived, the formula is shown alongside the result.
There are no sponsored slots, no premium positioning, no pay-to-rank. ChurnZero, Gainsight, Totango, and Vitally are compared on published pricing tiers and feature parity, not by any commercial relationship.
Outbound links to customer success platforms (ChurnZero, Gainsight, Totango, Vitally) and to source publishers (Bessemer, OpenView, ChartMogul, Recurly, ProfitWell) are plain unaffiliated URLs. This site is a reference, not a lead-generation funnel.
Benchmark sources are re-verified on the first business week of each month. Vendor pricing on the /tools comparison is checked against each vendor's own published tier or analyst sample. The last verified label currently reads May 2026.
The verification date is held in one constant (LAST_VERIFIED_DATE) imported by every page. Footer text, schema dateModified, and visible headings all read from that single source so cosmetic refreshes are not possible.
Every churn cost output on this site sums three layers (direct MRR loss, wasted CAC, destroyed LTV). The single-layer shortcut is the dominant industry error and the reason most operators under-state churn cost by 50 to 70 percent. The formulas are shown on every calculator.
Methodology in brief
Churn rate bands by segment come from Recurly Subscription Economy reports and ProfitWell research, cross-checked against ChartMogul SaaS Subscription Index public summaries. NRR and GRR benchmarks anchor to Bessemer State of the Cloud and the KeyBanc / Pacific Crest SaaS Survey, with OpenView SaaS Benchmarks used for triangulation. Valuation-multiple sensitivity to retention is sourced from SaaS Capital research and public 10-K filings for named SaaS comparables. Involuntary-churn statistics (the 9 percent of MRR figure, 20 to 40 percent of total churn, 60 to 70 percent smart-retry recovery) come from Recurly aggregate data and ProfitWell publications.
