name: churn-analysis
description: "Analyse customer churn for a product or cohort and produce a structured churn report. Use when asked to analyse churn, understand why customers are leaving, identify churn patterns, calculate churn rate, or build a churn reduction plan. Produces a churn analysis with rate calculations, categorised reasons, early warning signals, and prioritised interventions."

# Churn Analysis Skill
Produce a structured churn analysis that goes beyond the headline rate — identifying why customers leave, which segments are most at risk, and what interventions will have the highest impact on retention.
## Required Inputs
Ask for these if not already provided:
- **Time period** being analysed (e.g. Q1, last 12 months)
- **Total customers at start of period** and **customers churned**
- **ARR or revenue lost** to churn
- **Churn reasons data** — exit survey results, CSM notes, support data, or sales loss reasons
- **Customer segments** — by tier, industry, cohort, or product line
- **Current retention rate** if known
- **Any recent changes** — pricing, product, support model — that may have affected churn
## Churn Categories
Always classify churn before analysing it:
| Category | Definition |
|---|---|
| **Voluntary — avoidable** | Customer left due to a problem we could have addressed (product gaps, poor onboarding, relationship failures) |
| **Voluntary — unavoidable** | Customer left for reasons outside our control (budget cuts, acquisition, company shutdown) |
| **Involuntary** | Payment failure, contract non-renewal by mistake, admin error |
The interventions for each category are different. Conflating them leads to wrong conclusions.
## Output Format

# Churn Analysis: [Product / Segment / Company]
**Period:** [Start date] — [End date]
**Prepared by:** [Name] | **Date:** [Date]
---
## Headline Numbers
| Metric | Value |
|---|---|
| Customers at start of period | [N] |
| Customers churned | [N] |
| **Customer churn rate** | **[X]%** |
| ARR at start of period | £/$/€[X] |
| ARR lost to churn | £/$/€[X] |
| **Revenue churn rate (gross)** | **[X]%** |
| ARR from expansions (same period) | £/$/€[X] |
| **Net revenue retention (NRR)** | **[X]%** |
**Benchmark context:**
- Customer churn rate: [X]% vs. industry benchmark [Y]% — [above / below / in line]
- NRR: [X]% — [What this means: above 100% = expansion offsets churn; below 100% = shrinking base]
---
## Churn Breakdown by Category
| Category | Customers | % of churn | ARR lost |
|---|---|---|---|
| Voluntary — avoidable | [N] | [X]% | £/$/€[X] |
| Voluntary — unavoidable | [N] | [X]% | £/$/€[X] |
| Involuntary | [N] | [X]% | £/$/€[X] |
| **Total** | **[N]** | **100%** | **£/$/€[X]** |
**Avoidable churn as % of total churn:** [X]% — this is the number we can actually influence.
---
## Churn Reasons — Avoidable Churn Only
Rank by frequency. Include ARR weight where data allows.
| Reason | Count | % of avoidable churn | ARR lost | Representative quote |
|---|---|---|---|---|
| [Reason 1 — e.g. "Product missing key feature"] | [N] | [X]% | £/$/€[X] | "[Quote]" |
| [Reason 2] | [N] | [X]% | £/$/€[X] | "[Quote]" |
| [Reason 3] | [N] | [X]% | £/$/€[X] | "[Quote]" |
| [Reason 4] | [N] | [X]% | £/$/€[X] | "[Quote]" |
| Other | [N] | [X]% | £/$/€[X] | — |
**Theme synthesis:** [23 sentences grouping the top reasons into 23 themes. E.g. "The top three reasons cluster around two themes: product gaps in [area] (affecting X% of avoidable churn) and onboarding failures where customers never achieved value (Y%)."]
---
## Churn by Segment
Identify which segments over- or under-index for churn.
### By Tier
| Tier | Churn rate | vs. Overall | Notes |
|---|---|---|---|
| Enterprise | [X]% | +/-[X]pp | |
| Mid-Market | [X]% | +/-[X]pp | |
| SMB | [X]% | +/-[X]pp | |
### By Cohort (Acquisition Year)
| Cohort | Churn rate | Notes |
|---|---|---|
| [Year 1] | [X]% | |
| [Year 2] | [X]% | |
| [Year 3] | [X]% | |
### By Industry / Use Case (if data available)
| Segment | Churn rate | Notes |
|---|---|---|
| [Segment 1] | [X]% | |
| [Segment 2] | [X]% | |
**Key pattern:** [Which segment has the highest churn rate and what likely explains it]
---
## Timing Analysis
- **Average contract length before churn:** [X months]
- **Highest-risk moment:** [e.g. "Month 3 — when trial value has worn off but full adoption hasn't happened"]
- **Churn timing distribution:**
| When churn occurred | % of churned accounts |
|---|---|
| 03 months | [X]% |
| 36 months | [X]% |
| 612 months | [X]% |
| 12+ months | [X]% |
---
## Early Warning Signals
Based on the churned accounts, identify the signals that preceded churn (and could have triggered earlier intervention):
| Signal | Lead time before churn | How to detect |
|---|---|---|
| [Signal 1 — e.g. "DAU/MAU dropped below 15%"] | [~X weeks] | [Usage dashboard / alert] |
| [Signal 2 — e.g. "No QBR in 90+ days"] | [~X weeks] | [CRM flag] |
| [Signal 3 — e.g. "Champion left the account"] | [~X weeks] | [LinkedIn alert / CSM tracking] |
| [Signal 4] | [~X weeks] | [Detection method] |
---
## Intervention Recommendations
Ranked by estimated impact × feasibility.
| Intervention | Addresses | Est. churn reduction | Effort | Owner |
|---|---|---|---|---|
| [Intervention 1 — e.g. "Improve onboarding for [segment] with dedicated 30-day check-in"] | [Reason 1] | [X accounts / £X ARR] | Low / Med / High | [Team] |
| [Intervention 2] | [Reason 2] | [X accounts / £X ARR] | Low / Med / High | [Team] |
| [Intervention 3] | [Reason 3] | [X accounts / £X ARR] | Low / Med / High | [Team] |
**Priority call:** [Which one intervention, if implemented this quarter, would have the biggest impact and why]
---
## What We Don't Know (Data Gaps)
- [Data gap 1 — e.g. "Exit survey response rate is only 30% — the reasons data may not be representative"]
- [Data gap 2 — e.g. "No product usage data for SMB tier — can't confirm usage signal correlation"]
- [Data gap 3]
---
## Quality Checks
- [ ] Churn rate is correctly calculated (churned ÷ starting cohort, not end-of-period total)
- [ ] Avoidable and unavoidable churn are separated — interventions target avoidable churn only
- [ ] Churn reasons are customer-reported, not internally assumed
- [ ] Segment analysis identifies which segments over-index — not just averages
- [ ] Early warning signals are specific and detectable, not generic ("low engagement")
- [ ] Interventions link directly to the top churn reasons — no recommendations without a root cause match
