Reading these numbers: impressions are budget ÷ CPM × 1,000. Reach is your target audience × the reach % you expect, that’s the one assumption here, not something impressions alone can tell you. Frequency is impressions ÷ reach, how many times the average reached person sees the ad. GRPs are reach % × frequency, and CPP is budget ÷ GRPs.

Base the reach % on the platform, format, and flight length you’re planning against; it’s a planning assumption, the same one every media plan makes before it runs. Once the campaign is live, swap in the platform’s own reported reach here to get your real frequency.
