Completion Rate
The share of people who start a flow and finish it.
Completion rate = completed ÷ started × 100
Why it matters
It shows directly how much friction a flow has.
How to use it
- Measure it for each step of the flow.
- Look for the largest drop.
- Compare by device and user type.
Example
If 450 of 1,000 people finish sign-up, completion is 45%.
