Calculate GRP to measure the total weight of an advertising campaign.
% of target audience exposed at least once
Avg times each person sees the ad
Formula: GRP = Reach (%) × Frequency Total Impressions = Reach × Population × Frequency Cost per GRP = Budget / GRP
Understanding GRPs
GRPs measure the total weight of an ad campaign. 300 GRPs could mean 60% reach with 5 frequency, or 30% reach with 10 frequency. Higher GRPs mean more total ad exposure.
