Ad Revenue Calculator: Net RPM or Gross CPM
Project revenue using either a net RPM with its matching volume or gross advertising CPM and publisher share. Specify the revenue scope and rate yourself; channel lookup and current platform rates are not supplied.
Your numbers
How the calculation works
Estimate advertising or creator-platform revenue from a supplied RPM or an advertiser CPM and revenue share. The two modes use different denominators and should not be combined as though every view necessarily creates one ad impression.
Net-RPM income = views / 1,000 × net RPM. Gross-CPM income = ad impressions / 1,000 × gross CPM × publisher share.
Match the denominator
Use views with RPM and ad impressions with CPM. These counts can differ because one view may generate no advertising or more than one ad impression.
Apply the chosen rate
RPM mode multiplies views divided by 1,000 by net RPM. CPM mode multiplies ad impressions divided by 1,000 by advertiser CPM.
Apply revenue share where needed
Only the CPM calculation applies the entered publisher share to its gross advertising amount. Read the result under the selected scope rather than assuming every figure represents the same revenue definition.
Worked example: Net RPM scenario
Sample inputs demonstrate the method. They are not a forecast or product offer.
The first example uses net advertising RPM of €4 and 100,000 views. Dividing views by 1,000 gives 100 units of the rate, producing €400. No additional revenue-share deduction is applied in this mode.

Understanding your result
The output is a rate-and-volume scenario. It does not fetch platform analytics, current ad prices, channel performance or eligibility for monetisation.
Revenue is not profit. Production expenses, staff costs and taxes are not deducted, and an RPM based on total creator revenue can include amounts beyond advertising.
Questions you might have
Should I deduct the platform share from RPM again?
Not if your RPM already represents net publisher revenue. Doing so would deduct that share twice.
Choosing the right inputs
- Revenue basis
- Choose RPM when you know net revenue per thousand views. Choose CPM when you have advertiser cost per thousand ad impressions and a stated publisher share.
- Revenue included in the net RPM
- In RPM mode, identify whether the rate measures advertising alone or total creator-platform revenue. An all-source creator RPM should not be labelled ad-only earnings.
- Publisher share of gross revenue
- In CPM mode, enter the percentage of advertiser revenue retained. Do not apply this deduction again to a net RPM that already reflects the share.
Common mistakes to avoid
- Do not use channel views as ad impressions without evidence that the counts correspond.
- Do not subtract a platform share twice by treating an already net RPM as gross advertiser revenue.
Assumptions to check
- Use amounts in one currency and one reporting period. Results are labelled EUR; the arithmetic also works for another consistent currency.
- Views and ad impressions are different quantities. Enter a measured rate or an explicitly chosen scenario with the matching denominator.
