Read the example.
Quote A totals $13,000 for 500,000 supplied impressions: $20 media CPM and $26 all-in CPM. Quote B totals $10,500 for 400,000: $22.50 media CPM and $26.25 all-in CPM. A lower CPM does not establish a better audience or outcome.
The method
Assumptions and limits
- Impressions must be impressions, not visits, households, people or clicks. Supplied delivery can be a forecast, not a guarantee.
- Record geography, dates, audience, channel, inventory, viewability, frequency and measurement. This tool cannot verify them.
- Enter each cost once. Disclose taxes, minimums, exclusions, cancellation terms and production scope. A zero fee means you intentionally entered zero, not that missing fees were verified.
- Do not rank proposals as equivalent or choose a winner from CPM alone. No unduplicated reach or sales impact is inferred.
