CPM Calculator

Calculate your cost per thousand impressions (CPM) from advertising spend and impressions.

Total amount spent on the campaign(s) you're measuring.
The total number of times your ad was shown.

Formula

CPM = (Advertising Spend ÷ Impressions) × 1,000

CPM measures the cost of getting your ad seen, independent of clicks or conversions. It's most useful for comparing the cost of reach across campaigns, placements, or platforms.

Worked Example

If you spend $750 and receive 250,000 impressions, CPM = ($750 ÷ 250,000) × 1,000 = $3.00.
