Questions

CPM Calculator FAQ

Can I use this calculator to find out how many impressions I'll get for a fixed budget?
Yes. Enter your total budget and the CPM rate you're willing to pay, and the tool will calculate the number of impressions you can afford using the formula: impressions = 1000 × cost / CPM.
What is the formula behind the CPM calculations?
The core formula is CPM = 1000 × cost / impressions. The calculator also provides reversed equations: cost = CPM × impressions / 1000, and impressions = 1000 × cost / CPM, allowing you to solve for any variable.
Is there a way to compare two different ad campaigns using this tool?
Yes. The calculator includes an expandable menu labeled 'Second campaign' that lets you input variables for a second campaign and compare its costs and metrics alongside your first campaign.
Do I need to know the CPM rate before using the calculator?
Not necessarily. The tool works both ways—you can input any two of the three variables (cost, CPM, impressions) and it will calculate the third for you.
