Common questions

What file format does the customer churn analyzer accept?

CSV and Excel files from Stripe, ChartMogul, ProfitWell, or any export with customer ID, subscription dates, and status. The tool detects cancellation from a Cancellation Date column or a Status column showing 'canceled' or 'churned'.

How does it calculate churn rate correctly?

It counts unique customers who canceled in the period divided by customers active at the start, excluding plan changes and pauses unless they end in full cancellation. You can toggle between customer churn and revenue churn if your file includes MRR.

Can it identify at-risk customers before they cancel?

Yes, if your export includes engagement signals—Last Login Date, Feature Usage Count, Support Tickets. It segments customers by activity level and shows which low-engagement groups have higher historical churn, so you know who to reach out to.

Does it show cohort retention curves?

Yes. It groups customers by Subscription Start Date into monthly cohorts and calculates how many remain active each month after signup. The output is a table and a curve you can export, showing whether newer cohorts retain better than old ones.

What does the customer churn analyzer cost?

£39 per month or £390 per year. Both plans include unlimited uploads, cohort analysis, and at-risk segment detection. The annual plan saves £78 and includes priority support for custom churn definitions.
