Time to Convert
IntermediateTime to convert is the elapsed time between a user's first funnel step and the moment of conversion, computed only over the users who completed it.
The distribution is almost always right-skewed: most conversions happen early and a long tail of late deciders pulls the mean up, which is why the median reports it more honestly. The metric is capped by the conversion window: with a seven-day window nobody can exceed seven days, and widening the window raises both the conversion rate and the time to convert, so two reports with different windows are not comparable. The common misreading is treating a falling number as progress on its own. If the conversion rate fell at the same time, the likely explanation is that only low-hesitation users remain and the undecided ones dropped out earlier. The figure is wall-clock time and includes hours when the person was not in the product at all.
How it is calculated
Time to convert = median elapsed time between the first funnel step and the conversion event, across converting users
The population is only the users who reached the final step inside the conversion window; abandoners never enter the calculation, which makes the metric strongly dependent on that window. The unit is calendar time, reported in hours or days depending on the product. Using the mean instead of the median lets a handful of very long paths move the whole figure.
