Similarity between CPRP and CPT

Much like the CPRP, there is another concept which also measures the effectiveness of the programs or advertisements but is more globally accepted. It is the CPT or Cost Per thousand. It is a metric which calculates the cost incurred by the company to reach one thousand customers or households through the advertisement. The recent debates in TV buying prefers the use of CPT because CPT does not account for the stickiness or the viewing time by the audience. Cost Per Rating Point has anomaly because it considers the time. So even if the audience base and reach is growing, it may show a reduced rating point because of the stickiness factor. It becomes easier for broadcasters to increase prices as well.

CPT = Cost * 1000/ Target Audience

But both CPRP and CPT are important metrics to quantify the effectiveness of the advertisement and for media planners to adjust their cost.
