Radio Sales Exercise--Calculating GI, GRP, CPM, CPP

1. A client is targeting W 18-49 on your radio station. There are approximately 6000 women 18-49 in the market. You have proposed the following media plan:

Daypart AQH W 18-49 #Spots Spot price GIs

6-10 am 1200 10 $50

10-3 pm 600 4 $20

3-7 pm 900 6 $30

Step 1: Calculate the total GIs for the buy. GIs =

Step 2: You must convert the AQH persons to an AQH rating in order to calculate the GRPs (# spots X rating). (HINT: To get AQH rating, divide each AQH estimate by the total estimated population of W 18-49). Determine the AQH rating for each daypart, then calculate the total GRPs. (HINT: Convert the AQH Rtg into a whole number for easier calculations)

Daypart AQH W 18-49 AQH Rating GRPs

6-10 am 1200

10-3 pm 600

3-7 pm 900

Total GRPs =

Step 3: Now calculate a CPM estimate for the buy. To do that we need two items: total cost of the ad plan and the total GIs. We must add three zeros (000) to the ad cost before doing the calculation.

Total Cost + (000) =

GIs =

CPM =

Step 4: Calculate CPP. We need the total cost of ad plan divided by the total GRPs.

CPP =
