Funnel Conversion Calculator
Enter the users at each step and see exactly where your funnel leaks — step conversion, drop-off, and overall rate, visualized.
Two conversion numbers, not one
Every funnel has a step conversion (relative to the previous stage) and an overall conversion (relative to the top). Optimizing the wrong one wastes effort — a stage can look healthy overall while quietly halving the users who reach it.
Find the bottleneck first
The stage with the lowest step conversion is your highest-leverage fix: it is shedding the largest share of the users who got that far. Improve it before polishing stages that already convert well.
From a snapshot to a live funnel
This calculator works on numbers you paste in. Pug builds the same funnels from your real events — with average time between steps and the exact users who dropped, as open-source product analytics.
Frequently asked questions
- How do you calculate funnel conversion rate?
- Two ways. Step conversion = users at this step ÷ users at the previous step. Overall conversion = users at the last step ÷ users at the first step. This tool shows both, plus the drop-off at each stage.
- Where is my funnel leaking?
- Look for the step with the lowest step-conversion (the biggest percentage drop). That stage is costing you the most users relative to the one before it — fix it first.
- How many steps should a funnel have?
- Enough to isolate the decisions that matter, usually three to six. Too few hides where users drop; too many turns natural micro-actions into noise.
- How is this different from a conversion rate calculator?
- A conversion rate is a single number. A funnel breaks the journey into ordered steps so you can see exactly which transition fails — the same model Pug uses for funnel analysis.
