This is an estimate. Numbers are currency-agnostic — the tool treats your spend as plain units, so it works with any currency.
How to use
- Choose what you want to solve for: CPM, ad spend or impressions.
- Enter the other two values and the answer appears instantly.
- Read the comparison table to see how your budget stretches at different CPM levels.
Note: CPM = Spend / Impressions x 1000. Impressions = Spend / CPM x 1000. Spend = Impressions / 1000 x CPM.
Tips
- Always compare CPM with quality metrics — very cheap impressions often mean low visibility or irrelevant audiences.
- Use the comparison table before negotiating with a media seller to see what a better CPM is worth in reach.
- For budgeting, work backwards: decide the impressions you need, enter the platform average CPM, and solve for ad spend.
