Review Results
Use GRP to evaluate campaign reach, compare different campaigns, and plan advertising schedules for optimal exposure.
Formula
Gross Rating Points (GRP):
GRP = Reach (%) × Frequency
Note: GRP can exceed 100 when frequency is high
Example 1: Standard Campaign
Reach: 60%, Frequency: 3.5
GRP: 60% × 3.5 = 210 GRP
This means the campaign reached 60% of the audience an average of 3.5 times
Example 2: High Reach Campaign
Reach: 80%, Frequency: 2.0
GRP: 80% × 2.0 = 160 GRP
Wide reach with moderate frequency

Frequently Asked Questions
What is GRP and why is it important?
GRP (Gross Rating Points) measures total advertising exposure by multiplying reach (percentage of audience reached) by frequency (average impressions per person). It's important because it quantifies total campaign impact, allowing comparison across different media and campaigns.
Can GRP exceed 100?
Yes! GRP can exceed 100 when frequency is high. For example, if you reach 50% of the audience with a frequency of 3, GRP = 150. GRP over 100 indicates high frequency exposure, which can be good for brand awareness but may indicate overexposure.
What's a good GRP for a campaign?
Good GRP varies by campaign goals. For awareness: 100-200 GRP. For consideration: 200-400 GRP. For purchase intent: 400+ GRP. However, balance reach and frequency - very high GRP with low reach may indicate overexposure to a small audience.
How is GRP different from TRP (Target Rating Points)?
GRP measures exposure to the entire audience, while TRP measures exposure to a specific target audience. TRP is more relevant when you want to focus on a specific demographic. Use TRP when targeting is important, GRP for overall exposure.
How do I calculate reach and frequency?
Reach = (Unique Audience Reached / Total Target Audience) × 100%. Frequency = Total Impressions / Unique Audience Reached. These are typically provided by media research companies, Nielsen, or digital analytics platforms.
Is GRP still relevant for digital advertising?
GRP is primarily used for traditional media (TV, radio, print). Digital advertising typically uses metrics like impressions, reach, frequency, and CPM. However, some digital platforms provide GRP equivalents, and GRP can be useful for comparing traditional and digital campaigns.
