While the pipeline report above will show you contacts or deals who have had any of the selected lifecycle or deal stages, funnel reports show you only the number of contacts or deals in each stage that moved through the selected stages in order (i.e. Created > Marketing Qualified Lead > Customer) within the specified time period.
The report also calculates conversion rates at each step, showing you the percentage of contacts who moved from one stage to the next in the funnel. In the same example used above for contacts, if a contact was created, became a subscriber, then went straight to customer without ever becoming a lead, the contact will be reflected in Created, and Subscriber, but not Customer in the example below.
