CPM calculator for ad campaigns
Find what you paid for a thousand impressions and see how an assumed CPM affects a second budget.
By Drizzle team
CPM calculator
Calculate cost per thousand impressions and the impressions a planned budget would buy at an assumed CPM.
Work through an example
If $250 bought 20,000 impressions, CPM is $12.50. At that same price, $500 would buy about 40,000 impressions. The second number is only a planning estimate because auctions and placements can change.
Read the result carefully
Use impressions from the same spend period. CPM measures delivery price; it does not say whether anyone clicked or bought. Compare the result with click and purchase outcomes before changing creative.
Next step
Use the result to write one testable creative or budget decision. Keep the underlying report, date range, and assumptions beside it. For a product scene, take the verified facts into the Drizzle workspace.
