Formula and Logic
CPM (Cost Per Mille) is calculated as (Total Ad Cost / Total Impressions) * 1000. This tool uses standard industry formulas to derive all metrics:
- Ad Revenue/Cost: (Total Impressions / 1000) * CPM Rate
- Required Impressions (Advertiser Mode): (Total Ad Spend / CPM Rate) * 1000
- Estimated Clicks: (Total Impressions * Click-Through Rate) / 100
- Estimated Conversions: (Total Clicks * Conversion Rate) / 100
- Total E-Commerce Revenue: Estimated Conversions * Average Order Value
- Cost Per Click (CPC): Total Ad Cost / Estimated Clicks
- Cost Per Acquisition (CPA): Total Ad Cost / Estimated Conversions
All calculations round to two decimal places for clarity, and currency formatting matches your selected currency.
Practical Notes
These real-world tips help you apply your results to business operations:
- Average CPM rates for display ads range from $1 to $10 for general audiences, and up to $50 for niche B2B audiences.
