CPM Formula:
| From: | To: |
CPM (Cost Per Mille) is a marketing metric that represents the cost an advertiser pays for one thousand impressions or views of an advertisement. It's a standard measurement in digital advertising to compare the cost effectiveness of different advertising campaigns.
The calculator uses the CPM formula:
Where:
Example: If you spent $5000 for 100,000 impressions, your CPM would be:
CPM = (5000 / 100000) × 1000 = 50
Details: CPM helps advertisers compare the efficiency of different advertising channels, optimize campaign budgets, and measure the cost-effectiveness of their marketing efforts. Lower CPM values generally indicate more efficient advertising spend.
Tips: Enter the total cost of your advertising campaign in dollars and the total number of impressions received. Both values must be positive numbers (cost > 0, impressions ≥ 1).
Q1: What's a good CPM rate?
A: CPM rates vary widely by industry, platform, and targeting. Generally, CPMs between $1-$10 are considered good for digital display advertising, while social media CPMs often range from $5-$15.
Q2: How does CPM differ from CPC?
A: CPM charges per thousand impressions, while CPC (Cost Per Click) charges for each click on an ad. CPM is better for brand awareness campaigns, while CPC is better for direct response campaigns.
Q3: Can CPM be used for all advertising types?
A: CPM is most commonly used for display, video, and social media advertising. It's less common for search advertising, which typically uses CPC pricing.
Q4: How can I lower my CPM?
A: Improve ad relevance, target more specific audiences, optimize ad creative, and test different advertising platforms to find the most cost-effective options.
Q5: Does a lower CPM always mean better performance?
A: Not necessarily. While lower CPM means cheaper impressions, you should also consider conversion rates and return on ad spend (ROAS) for a complete picture of campaign performance.
