1. What is GRP?

GRP (Gross Rating Points) is a standard measure in media planning that represents the total audience impressions as a percentage of the target population. It helps quantify the total exposure of an advertising campaign.

2. How Does the Calculator Work?

The calculator uses the GRP equation:

Where:

• \( Impressions \) — Total number of times the ad was seen
• \( Universe \) — Size of the target population

Explanation: GRP measures the percentage of the target audience reached multiplied by the average frequency of exposure.

3. Importance of GRP Calculation

Details: GRP helps media planners compare the effectiveness of different campaigns, allocate budgets efficiently, and estimate the potential reach of advertising efforts.

4. Using the Calculator

Tips: Enter total impressions (can be greater than universe due to repeated views) and the size of your target population. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between GRP and reach?
A: Reach is the percentage of unique individuals exposed, while GRP accounts for frequency (reach × average frequency).

Q2: Can GRP be more than 100?
A: Yes, GRP can exceed 100 when the average person sees the ad multiple times (frequency > 1).

Q3: How does GRP relate to TRP?
A: TRP (Target Rating Points) is similar but focuses on a specific demographic within the universe.

Q4: What are typical GRP values for campaigns?
A: Varies by medium and goals, but TV campaigns often aim for 100-300 GRPs per week.

Q5: How does digital media measure GRP?
A: Digital GRP uses viewable impressions and matches them to target audience data.
