The gross rating points of a radio schedule are the sum of all ratings points delivered by that schedule, or the gross impressions expressed as a percentage of the population being measured. It can be computed as follows: Gross rating points = (Gross impressions/Population) * 100. Gross impressions = AHQ persons * No. of spots the advertiser wants to buy = 9900 * 20 = 198000. Gross rating points = (198000/48000) * 100 = 412.5 GRPs.
