Sales funnel analysis
Step 1 of 3 — Funnel data

Enter your sales funnel numbers

Use the same time period and, where possible, the same lead cohort for all numbers.

Long sales cycle?
If your sales cycle lasts weeks or months, follow a defined lead cohort from entry to outcome rather than comparing unrelated monthly totals.

A few questions for better context

These fields are optional and are used only to add context to the analysis.

How this tool thinks

The tool calculates conversion and drop-off across five transitions. It combines drop severity and volume impact to prioritize investigation. If previous-period data is added, historical deterioration is included as additional evidence.

Diagnostic limitation
The tool identifies a useful place to start investigating; it does not claim a cause without evidence and business context.
