What is a Gross Rating Point (GRP)?

A GRP is a standard unit measuring total advertising exposure. One rating point equals 1% of the target market population. If 60% of an audience sees an ad 3 times, the campaign delivers 180 GRPs.

Can GRP exceed 100 points?

Yes! GRPs routinely exceed 100, 500, or 1,000 points because frequency multiplies the percentage reach. 80% reach at 5x frequency equals 400 GRPs.

How does GRP differ from TRP (Target Rating Points)?

GRP measures exposure across the broad total population, while TRP measures exposure strictly within a defined target demographic (e.g. Females aged 25-54).

What is Cost Per Point (CPP)?

Cost Per Point (CPP = Total Ad Cost / Total GRP) is the pricing benchmark media buyers use to evaluate the cost-effectiveness of TV and radio commercial packages.

How do GRPs convert into total gross impressions?

Gross Impressions = (GRP / 100) × Total Target Population. For example, 200 GRPs in a market of 1,000,000 people generates 2,000,000 total ad impressions.

What is effective frequency in media planning?

Effective frequency is the minimum number of times (typically 3 to 5 exposures) a consumer must see an ad before message recall and purchase intent occur.

Quick Definition & Answer

What is the GRP Calculator (Gross Rating Points)?

Gross Rating Points (GRP) calculation measures the total advertising impact and media weight of an advertising campaign across target audiences. It multiplies the percentage of target audience reached by the average exposure frequency of the advertising message across selected media channels. This enables media planners and brand marketing teams to evaluate campaign coverage, compare competing media buys, and optimize advertising spend efficiency.

The GRP (Gross Rating Points) Calculator measures total advertising campaign weight and exposure intensity across broadcast television, radio, print, and cross-channel media plans.
