About this tool
What the Brand Awareness Reach Calculator does
Awareness campaigns are bought in impressions but judged on reach: the number of different people who saw the ad. Reach is impressions divided by average frequency, and this calculator also shows what share of your target audience that covers.
Formula
- Impressions = budget ÷ CPM × 1,000
- Reach = impressions ÷ average frequency
- Audience coverage = reach ÷ target audience size
- Cost per 1,000 reached = budget ÷ reach × 1,000
Worked example
Using the starting values in the calculator above:
| Input | Value |
|---|---|
| Campaign budget | $10,000 |
| CPM | $8.00 |
| Average frequency | 3 per person |
| Target audience size | 500,000 |
| Result | Value |
|---|---|
| People reached | 416,667 |
| Share of target audience | 83.3% |
| Impressions | 1,250,000 |
| Cost per 1,000 people reached | $24.00 |
How to read the result
Reach and frequency trade off against each other for a fixed budget. Raising frequency from 2 to 4 halves the number of people you reach, so decide first whether the brief needs more people or more repetition.
Platforms report reach from their own deduplication, which this estimate cannot replicate exactly. Use the platform reach forecast once the audience is built.

Questions
Questions about this tool
The things clients actually want to know — costs, timelines, ownership and what happens after launch.
Impressions count every time an ad is shown. Reach counts the number of different people who saw it at least once.
Two to four exposures over a campaign flight is a common planning range, but the right level depends on creative, competition and how new the brand is.
Once most of the audience has been reached, extra budget mainly increases frequency, so reach climbs more and more slowly.
