Frequently asked questions
▶Are these SaaS churn tools really free?
Yes. Every calculator and AI tool on this page is free with no signup. The 5 calculators (churn rate, LTV, revenue recovery, SaaS quick ratio, cohort retention) run entirely in the browser. The 2 AI tools (exit-survey generator, cancellation-email teardown) call Claude on RetentionCheck's API quota and are rate-limited per IP. The full RetentionCheck analysis at /try is also free for 3 analyses/month.
▶Which tool should I use first?
Depends on what you have. If you have raw cancellation feedback (forms, tickets, emails), start with RetentionCheck at /try - the analysis tells you which patterns to fix first. If you have just the numbers, start with the churn rate calculator to see the revenue impact, then the revenue recovery calculator to size the upside. If you have neither yet, start with the exit survey generator to ship a 6-question survey today.
▶Do I need a billing integration to use these tools?
No. All 7 tools accept manual input or text paste. The calculators take numbers you already know (MRR, customer count, churn rate). The AI tools take text. None require a Stripe, Recurly, or Chargebee connection. Optional integrations exist for the full RetentionCheck analyses page if you want auto-import from Stripe Connect, Intercom, or Typeform.
▶What's the difference between the calculators and the AI tools?
Calculators do math on numbers you provide and return a result instantly. AI tools take unstructured input (a product description, a single cancellation email) and return reasoning - severity scores, suggested replies, ranked drivers - using Claude. The AI tools are slower (5-15 seconds) and rate-limited but produce qualitative output that calculators cannot.
▶How accurate are the SaaS benchmarks these tools reference?
The calculators don't include benchmarks; they compute on your numbers. For benchmark comparisons, use /churn-benchmarks (108 industry-specific benchmark pages with monthly + annual churn rates, top drivers, and median ARPU). Benchmarks pull from public industry research and RetentionCheck's analyzed cancellation feedback, last refreshed 2026-03-31.
