Target Rating Point, often shortened to TRP, is a core advertising metric used to understand how much of a defined target audience was exposed to an ad. Instead of measuring exposure across an entire population, TRP focuses specifically on the audience segment you want to reach, making it far more useful for precision media planning.
TRP helps advertisers answer a simple but critical question.
How effectively are we reaching the people who matter most for this campaign
A Target Rating Point represents the percentage of your defined audience that has been delivered impressions from an ad campaign. Unlike general reach metrics, TRP isolates performance within a selected group such as women aged twenty five to forty four, sports fans, or frequent travelers.
Even though TRP is expressed as a percentage, it is represented as a point value. Since the calculation uses impressions, TRP can exceed 100 points if the audience receives more total impressions than the size of the audience itself.
For example, if your campaign delivered enough impressions to equal two full exposures for the entire target audience, the TRP would be 200.
The calculation is straightforward.
TRP equals total impressions delivered to the target audience divided by the size of the target audience, multiplied by one hundred.
If a campaign generates five hundred impressions among two thousand people in the target audience, the TRP is:
500 divided by 2000 multiplied by 100 equals 25.
This means your campaign delivered impressions equal to twenty five percent of your target audience.
TRP and GRP are closely related, but they measure exposure in different groups.
GRP measures exposure among the entire audience.
It shows how heavily the campaign was delivered to the full population watching or listening.
TRP measures exposure only among your defined target audience.
It filters out impressions wasted on people outside your intended segment.
A simple example.
If forty percent of all viewers saw your ad once, that is forty GRPs.
If your target audience makes up half of that entire population, the same delivery equals twenty TRPs.
Both TRP and GRP accumulate over time. If your ad airs five times and delivers individual TRPs of twenty, twenty five, thirty, twenty eight, and twenty seven, the total equals one hundred thirty TRPs.
This number, however, does not guarantee that one hundred thirty percent of your audience actually saw the ad. It only quantifies impressions, not confirmed viewers. This is why TRP informs planning but should be paired with qualitative insights and real performance data.
Helps optimize budget allocation
By focusing only on the people you want to reach, TRP exposes wasted spend and highlights the channels that best deliver your core audience.
Shows the depth of exposure
Because TRP includes frequency, it helps you understand whether your audience saw the ad often enough to drive recall or action.
Improves campaign relevance
Campaigns become more efficient when impressions are concentrated within the right group rather than the general population.
Supports media planning decisions
TRP guides buying strategies, channel selection, flighting schedules, and adjustments to reach and frequency goals.
No metric is perfect. TRP comes with a few considerations.
To get the full picture, TRP should be paired with performance metrics such as conversions, lift studies, engagement measures, and brand tracking.
Target Rating Point. It measures how much of a target audience has been delivered impressions from an ad.
Yes. Because TRP uses impressions instead of unique reach, repeated exposures can exceed the size of the audience.
Reach measures unique people exposed at least once. TRP measures total impressions relative to the audience size.
Neither is better. TRP is more precise for targeted campaigns. GRP is more useful for broad advertising such as national television.
Television, connected TV, digital video, audio advertising, and any campaign with a defined demographic or behavioral audience.
