Target Rating Point (TRP)

Used interchangeably with Gross Rating Point (GRP), a TRP is a figure that represents 1 percent of the target market reached. A television program delivering 5 TRPs is reaching 5 percent of the target audience being measured. In a media schedule with multiple ad exposures being delivered, TRPs are determined by multiplying the reach of the schedule and the average frequency of exposure. The formula for a reach of 30 and frequency of 3 is 30 X 3 = 90 TRPs.
