Per-tool: what to know before you plug it in
Billing platform
Subscription billing platform with built-in dashboards and SQL analytics (Sigma).
Before you adopt: Stripe reports both customer (logo) and revenue churn. Voluntary vs involuntary (failed-payment) churn must be separated manually — Stripe lumps them together by default. Cancellations scheduled for period-end count when the period ends, not when scheduled.
Pricing: Pay-as-you-go (2.9% + $0.30 per charge). Sigma analytics: free up to 1K charges/mo, then $0.02/charge.
Billing platform
Merchant-of-record billing for SaaS; ProfitWell metrics now bundled.
Before you adopt: Paddle's churn metric defaults to revenue churn. Watch the distinction between voluntary churn and dunning failures — Paddle's Retain add-on inflates apparent retention by recovering failed payments, which is good for your business but obscures the underlying churn signal.
Pricing: 5% + $0.50 per transaction (Merchant of Record model — Paddle handles VAT/sales tax globally).
Billing platform
Subscription billing platform with deep enterprise feature set and analytics module.
Before you adopt: Chargebee distinguishes 'cancelled' from 'paused' from 'non-renewing.' Decide upfront which states count as churn — pause-then-resume can artificially flatten the curve if you mark pauses as churned.
Pricing: Free up to $250K ARR; from $599/mo (Performance) for established SaaS.
Billing platform
Merchant-of-record billing for indie SaaS and digital products with a built-in analytics view.
Before you adopt: Lemon Squeezy reports subscription statuses (active / past_due / unpaid / cancelled) but not a packaged churn rate. You'll compute monthly churn yourself by exporting the subscription log.
Pricing: 5% + $0.50 per transaction (also merchant of record).
RevenueCat
SDK / integrationMobile subscription
Cross-platform mobile subscription SDK with analytics for iOS, Android, and web in-app purchases.
Before you adopt: Mobile churn includes 'silent' churn (auto-renew off but still active until period-end) — RevenueCat surfaces this separately. Watch the difference between 'cancellation' (renewal off) and 'lapsed' (period ended without renewal).
Pricing: Free up to $2.5K MTR; then 1% of tracked revenue.
Mobile subscription
Mobile subscription analytics with paywall A/B testing engine.
Before you adopt: Adapty separates trial churn from paid churn — critical distinction for mobile. Most apps obsess over paid churn but the bigger lever is trial → paid conversion, which Adapty tracks in the same view.
Pricing: Free up to $10K MTR; then ~$249/mo for Pro.
SaaS analytics
Subscription analytics platform built for funded SaaS with Stripe/Recurly/Chargebee billing.
Before you adopt: Both customer and net MRR churn views are first-class. The 'segments' feature lets you compute churn by plan, cohort, or any custom attribute — invaluable for diagnosing where churn is concentrated.
Pricing: Free up to $10K MRR; then from $129/mo (Launch) to $799+/mo (Volume).
SaaS analytics
Stripe-native subscription analytics with cancellation surveys and dunning.
Before you adopt: Cancellation surveys (Insights add-on) attach qualitative reason data to each churn event — the data is uniquely good. Without Insights, you only see the number, not the why.
Pricing: From $129/mo (Metrics) to $429+/mo (Business) — seat and MRR limits.
ProfitWell (Paddle)
AutomaticSaaS analytics
Free Stripe-connected subscription metrics, now Paddle-owned.
Before you adopt: Customer and revenue churn split out cleanly. ProfitWell's industry benchmark dataset (median churn by ARPU band) is built into the dashboard — useful for context but be careful: aggregate medians hide enormous variance.
Pricing: Metrics are free; Retain (failed payment recovery) and Price Intelligently are paid add-ons.
Mixpanel
Computed (SQL / export)Product analytics
Event-based product analytics for funnels, retention, and cohort analysis.
Before you adopt: Mixpanel can't directly measure subscription churn (no billing data), but its retention report measures behavioral churn — users who stop using the product. The two diverge: a customer who pays but doesn't log in is paid-active but behaviorally churned, often a leading indicator of cancellation.
Pricing: Free up to 1M events/month; from $24/mo (Growth) to enterprise.
Amplitude
Computed (SQL / export)Product analytics
Event-based product analytics with strong cohort and behavioral retention tooling.
Before you adopt: Like Mixpanel, behavioral churn — not billing churn. Amplitude's cohort + retention charts are best-in-class for understanding which user behaviors predict cancellation. Pair with billing data for the full picture.
Pricing: Free up to 50K MTU; from $49/mo (Plus).
PostHog
Computed (SQL / export)Product analytics
Open-source product analytics with self-hosting option.
Before you adopt: Same behavioral-not-billing caveat as Mixpanel and Amplitude. Self-hosting on your own infra means no per-event cost — viable for SaaS at scale where Mixpanel becomes expensive.
Pricing: Free up to 1M events/month; usage-based after.
Saasly Calculator
Manual entryManual calculator
Manual-entry calculator that computes the core SaaS metrics with Skok-tier classification.
Before you adopt: Enter customers lost and customers at start — get monthly churn rate and benchmark band. Saasly's wiki explains the customer-vs-revenue churn distinction in depth.
Pricing: Free forever, no signup.
