This calculator helps you measure CPM (cost per 1,000 impressions), a key metric in display and awareness advertising campaigns.
CPM shows how much you pay to display your ad 1,000 times. It is commonly used in banner ads, programmatic advertising, and brand awareness campaigns.
Formula: CPM = (Spend ÷ Impressions) × 1000
The result shows how much you are paying per 1,000 impressions.
The calculator divides total spend by impressions and multiplies the result by 1,000.
Example 1: £120 ÷ 50,000 × 1000 = £2.40
Example 2: £75 ÷ 10,000 × 1000 = £7.50
Cost per 1,000 impressions.
