Funnel Drop-Off Calculator

Map each funnel step, find where the largest group of users drops out, and estimate the upside from fixing that leak.

The calculator uses each step count as a snapshot cohort. Keep counts in descending funnel order and use the same date range for every row.

The calculator updates automatically as you edit step names and counts.

When to use it

Use this after an analytics pull for landing pages, onboarding, signup, checkout, or product activation funnels.

How upside is estimated

The model reduces the biggest leak's drop-off rate, then carries the additional users through the remaining funnel at current rates.

Data guardrails

  • Use one cohort and one reporting window.
  • Avoid mixing unique users with event counts.
  • Validate tracking before prioritizing fixes.
