Funnel Drop-off Calculator
Find the leak. Enter the number of people at each stage of your funnel and see the conversion and drop-off between every step, plus your overall top-to-bottom rate.
How to use it
List your stages from top to bottom, for example Visitors, Signups, Trials, then Paid. The calculator shows the conversion from each step to the next and flags the single worst drop-off, which is usually where the next experiment pays off most.
Once you know the leak, fix it with a hypothesis and a test, not a guess: see the A/B testing program guide, landing page optimization, and, for the activation step, activation metrics.
