Funnel charts are a type of chart, often used to represent stages in a sales process and show the amount of potential revenue for each stage. This type of chart can also be useful in identifying po tential problem areas in an organization’s sales processes. A funnel chart is similar to a stacked perc ent bar chart.

A funnel chart displays values as progressively decreasing proportions amounting to 100 percent in total. The size of the area is determined by the series value as a percentage of th e total of all values. Any funnel consists of the higher part called head (or base) and the lower part r eferred to as neck

Ideally the funnel chart shows a process that starts at 100% and ends with a lower percentage where it is noticeable in what stages the fall out happens and at what rate. If the cha rt is also combined with research data, meaning quantified measurements of just how many items are lost at each step of the sales or order fulfillment process, then the funnel chart illustrates where the big gest bottlenecks are in the process.
