Earned media value (EMV)
Earned media value estimates what a campaign's reach would have cost if you had bought it as advertising.
EMV turns contacts reached into a euro amount that you can set against the cost in your reporting. It is not revenue. The result depends heavily on the assumed CPM, so always state the CPM you used.
Calculation
Example: A campaign reaches 400,000 contacts. At a CPM of €35, that is 400,000 ÷ 1,000 × €35 = €14,000 in earned media value.
