Cost Per Rating Point (CPRP) Formula
The following equation is used to calculate the cost per rating point (CPRP).
CPRP = TCC / GRP
- Where CPRP is the total cost per rating point ($/RP)
- TCC is the total campaign cost ($)
- GRP is the gross rating points (the sum of rating points across all ads in the campaign; 1 rating point = 1% of the defined target audience)
To calculate the cost per rating point, divide the total campaign cost by the gross rating points.
What is Cost Per Rating Point (CPRP)?
Definition:
Cost Per Rating Point (CPRP) is a media buying metric commonly used in television and radio advertising to describe the cost to deliver one rating point (i.e., 1% of a defined target audience) for an ad or campaign. Advertisers use CPRP to compare the cost efficiency of different placements or schedules that deliver different numbers of rating points/GRPs. The formula used to find the cost per rating point is:
How to Calculate CPRP?
Example Problem:
The following example outlines the steps and information needed to calculate CPRP.
For example, suppose a TV ad costs $4,000 and delivers an 8 rating (8 rating points), meaning it reaches 8% of the defined target audience. If the target audience universe is 10,000,000 people, then 8% corresponds to 800,000 viewers. The cost per rating point would be: $4,000 / 8 = $500 per rating point.
The cost per rating point tells you how much you’re spending for each rating point (each 1% of the defined target audience) delivered by your advertisement or campaign.
