How it works
Propagate stage rates
Each stage count is the previous count multiplied by its conversion rate; the score is their geometric mean.
Find the narrowest stage
The lowest entered conversion rate is highlighted as the first place to investigate, not automatically optimise.

Frequently asked questions
Are these conversion benchmarks?
No. The calculator uses only your assumptions or observed rates and does not invent industry averages.
What does the score mean?
It is the geometric mean of the four entered conversion rates, giving a balanced 0–100 summary without hiding the actual stage volumes.
Should I optimise the lowest rate first?
Investigate it first. The biggest business opportunity also depends on volume, user intent, cost, and strategic importance.
