How this calculator works
Impressions = budget ÷ CPM × 1,000. Lower CPMs buy more impressions, so improving relevance and broadening targeting stretches your reach further.
Frequently asked questions
How many impressions will $1,000 get me? +
At an $11 CPM, roughly 91,000 impressions. Divide your budget by CPM and multiply by 1,000 for any figure.
Do impressions equal people? +
No — impressions count every time the ad is displayed. To estimate unique people, divide impressions by frequency.
Do impressions count the same person twice? +
Yes. Every time the ad is shown counts as an impression, even to the same person. To estimate unique viewers, divide impressions by your frequency.
How can I get more impressions for the same budget? +
Lower your CPM by broadening targeting, improving ad relevance, and choosing cheaper placements such as Audience Network, all of which buy more impressions per dollar.
Are impressions the same as reach? +
No. Impressions are total displays; reach is unique people. If 1,000 people each see your ad twice, that is 2,000 impressions but only 1,000 reach.
