How is GRP calculated?

Gross Rating Points (GRP) is a standard measure in advertising that quantifies the total exposure of an advertisement to its target audience over a specific period of time. The calculation of GRP involves the product of frequency and the reach of the target audience.

The correct calculation method is Frequency multiplied by the Percentage of Target Audience Reached. This formula effectively captures the total impact of an advertising campaign by showing how often, on average, the target audience is exposed to the advertisement (frequency) and what portion of that audience has actually been reached.

In this context, frequency refers to the number of times an average person in the target audience sees the advertisement, while the percentage of the target audience reached signifies how many unique individuals from the target demographic have been exposed to the message at least once. Thus, combining these two factors provides a comprehensive measure of the advertisement's effectiveness and helps advertisers analyze the potential reach and repetitiveness of their messaging within the intended audience.
