How is TRP calculated?

Answer 1

1. tep1

   Use this formula to determine TRP:

   TRP = GRP x Percentage of target audience

2. Step2

   Determine the numbers. For example, an ad airs with 43 percent of viewers seeing it each of three times it aired. The target demographic is 20 percent of the total audience.

3. Step3

   Find the GRP, which is rate x frequency. In the above example, the rate of viewers (43 percent) x the number of times it is seen (three) = GRP. 43 x 3 = 129 gross rating points.

4. Step4

   Plug the GRP into the formula. GRP (129) x target audience percentage (20 percent) = TRP. 129 x .20 = 25.8 target rating points.

5. Step5

   Interpret the numbers. Generally, TRP should average between 100 and 300 per week. Extremely good would be 400 or more, and less than 100 is ineffective. The score of 25.8 in this example shows an ineffective ad campaign
