Funnel Drop-off

The share of people lost between one step of a journey and the next.

Drop-off = (people at step − people at next step) ÷ people at step × 100

Why it matters

It shows where the problem is, before you try to work out why.

How to use it

  • Map the steps people must take.
  • Compare before and after a release.
  • Split by device, because problems often hide in one segment.

Example

If 5,420 people reach Payment and 2,710 pay, 50% drop off at that step.
