The formula to calculate GRP is:
\[ \text{GRP} = \left(\frac{\text{Audience Reached}}{\text{Total Target Audience}}\right) \times \text{Frequency per Viewer} \times 100 \]
Gross Rating Points (GRP) is a standard measure in advertising that quantifies the total exposure of an advertisement. It's calculated by multiplying the percentage of the target audience reached by the frequency with which they are exposed to the ad. This helps advertisers gauge the overall impact of their campaigns.
Let's consider a TV ad with the following details:
To calculate the GRP:
\[ \text{Reach Percentage} = \frac{2,000}{10,000} \times 100 = 20\% \]
\[ \text{GRP} = 20 \times 4 = 80 \text{ points} \]
