Frequently Asked Questions
How is GRP calculated?
GRP = Reach (as a decimal fraction of total audience) x Frequency x 100. For example, reaching 20% of your audience an average of 4 times each gives a GRP of 80.
Can GRP exceed 100?
Yes. Unlike reach percentage alone, GRP has no upper limit -- since it multiplies in frequency, a campaign that reaches its full audience multiple times can produce a GRP well over 100.
