Quick read
The main number to watch here is drop-off rate. A high drop-off rate means a large share of traffic or leads is failing to advance to the next stage.

How to find funnel leaks
↗Learn how to find the biggest leaks in a funnel by measuring stage pass-through, comparing cohorts, and separating traffic problems from page or offer problems.

Formula
Drop-Off Rate = ((Stage 1 Volume - Stage 2 Volume) / Stage 1 Volume) × 100
Funnel drop-off rate shows what share of people or opportunities fail to move from one stage to the next. It is useful because it turns vague funnel leakage into a specific percentage you can compare across steps, pages, and cohorts.
How to use this calculator
- 1Enter the volume at the earlier stage of the funnel.
- 2Enter the volume that reached the next stage.
- 3The calculator shows both drop-off rate and pass-through rate so you can see the loss and the retained share together.
What this metric tells you
A high drop-off rate means a large share of traffic or leads is failing to advance to the next stage.
The result becomes more actionable when you compare multiple steps to identify where the biggest leak is happening.
This metric is especially useful when paired with stage-specific rates like visitor-to-lead, signup rate, or checkout conversion rate.
Common use cases
- Measuring leakage between landing-page visitors and leads.
- Checking where a multi-step signup or checkout flow loses the most people.
- Prioritizing which funnel step deserves diagnostic work first.

Worked example
Example: calculating funnel drop-off between two stages
If 5,000 people reach stage one and 3,250 move to stage two, drop-off rate is 35.00% and pass-through rate is 65.00%. That means just over one third of the cohort leaks out before the next step.
FAQ
What is funnel drop-off?+
Funnel drop-off is the share of people who do not move from one stage to the next. It helps you quantify leakage instead of describing it loosely.
Why show pass-through rate too?+
Pass-through rate shows the retained share that made it to the next stage, which helps balance the drop-off number and makes step comparisons easier.
Can a high drop-off rate still be normal?+
Yes. Some steps naturally have lower pass-through, especially in higher-consideration funnels, but the key is comparing the rate against your own baseline and nearby steps.
How do I use this to find funnel leaks?+
Run the calculation for each stage transition, then prioritize the step with the highest drop-off or the biggest recent deterioration for deeper diagnosis.
