Cost per thousand for a broadcast schedule can be
determined from the cost per target audience rating point
(abbreviated cost per point or CPP).

Two factors must be known:

1. CPP, which is simply the cost of the schedule
   divided by the schedule's number of GRPs.
2. The total population of the target audience.

The formula for finding CPM from CPP is as follows:

CPM = (CPP X 100) / Population
1000
