# Coverage of KPIs

In the Marketing efforts module, it is possible to filter KPIs using a zone filter. For some of these KPIs it is relevant to know what the ratio is compared to the same KPI without a zone filter. This is what the coverage expresses.

Say you apply a zone filter in which you draw an isochrone of 0-10 minutes around all own locations and you focus on the KPI *real sales*. The *coverage* is the ratio of the real sales with the zone filter applied over the real sales of all zones (i.e. without any zone filter applied). In the example below, this is a coverage of 64%, that is, 64% of the real sales are realized in the 0-10 minute isochrone.

The coverage will be most relevant for the KPIs *Market Potential*, *Real Sales*, and *Predicted Sales*.
