# Earned Media Value Calculator for B2B Events | Attendir

Free Calculator

Earned Media Value Calculator
=============================

 Put a defensible dollar figure on the organic LinkedIn reach your B2B event generates. Every assumption is stated and editable — delivered impressions, CPM, and an honest engagement adjustment. No invented multipliers.

 

Your event's sharing reach
--------------------------

 Expected attendees 300 

  

 Share rate (% who post) 25% 

 Well-run campaigns land at 20-40%. See the [benchmark report](https://attendir.com/event-sharing-benchmark).

 

 Delivered impressions per share 150 

 Delivered impressions from post analytics — not connection counts. LinkedIn organic delivery typically lands at 50-150 per share.

 

 Channel CPM (USD) $35 

 $30-45 is a planning placeholder for B2B LinkedIn. Replace it with your own campaign CPMs when you have them.

 

Engagement adjustment

  0.8×

Low engagement

 

   1.0×

Default

 

   1.2×

Measured high

 

  

Keep 1.0 unless you can publish the reasoning. Credibility belongs in your conversion rates, not in a multiplier.

 

 

Your earned media value
-----------------------

 Attendees who share 75 

 Delivered LinkedIn impressions 11,250 

 EMV per attendee $1.31 

 

Earned media value per event

$394

11,250 ÷ 1,000 × $35 × 1.0

 

 This is a **budget-equivalence figure**: what buying the same delivered impressions would cost at your stated CPM. It is not revenue or pipeline — for the full method and its limits, read the [earned media value guide](https://attendir.com/blog/earned-media-value-events).

The Formula

How this calculator works
-------------------------

EMV = (Delivered impressions ÷ 1,000) × Channel CPM × Engagement adjustment

 

Impressions, not connections

 Network size is not reach. The feed algorithm delivers any single post to a fraction of a person's network, so this calculator asks for *delivered* impressions per share — the number most EMV models silently inflate.

 

A CPM you can defend

 The default $35 CPM is a stated planning placeholder for B2B LinkedIn, not a published rate. Your own campaign CPMs are always the better input — the result inherits the credibility of the CPM you choose.

 

No trust multipliers

 Peer content earns more trust than ads — and that trust shows up in [conversion metrics you can measure](https://attendir.com/blog/event-sharing-roi-metrics), not in a 3× multiplier. The adjustment here stays between 0.8 and 1.2.

 

 

### From estimate to measurement

 A calculator gives you a planning estimate; per-advocate tracking replaces it with measured data. Attendir gives every attendee a branded LinkedIn sharing card and a tracked landing page, so you see actual clicks and registrations per advocate — the measured inputs an honest EMV model needs. Pair this figure with [registration-based ROI](https://attendir.com/event-roi-calculator) to cover both sides of the budget conversation.

 

 

Frequently asked questions
--------------------------

### What CPM should I use to calculate earned media value on LinkedIn?

Use your own recent campaign CPMs whenever you have them — they are the only numbers you can fully defend. Without campaign history, $30-45 is a reasonable planning placeholder for B2B LinkedIn feed placements. Whichever number you pick, state it next to the result; an EMV figure is only as credible as its stated CPM input.

 

### What counts as an impression in an EMV calculation?

Delivered impressions from post analytics — never connection or follower counts. The feed algorithm shows any single post to a fraction of a person's network, so network size dramatically overstates reach. If you cannot access post analytics, model impressions from measured clicks divided by a stated click-through rate.

 

### Is earned media value the same as advertising value equivalency (AVE)?

EMV descends from AVE, which measurement bodies like AMEC explicitly reject as a measure of communications value. The defensible use of EMV is budget equivalence: it estimates what replacing your organic reach with paid media would cost. It is not revenue, not pipeline, and not proof of impact.

 

### Should I apply a trust multiplier to peer-shared content?

No. Peer content is more credible than ads, but that credibility shows up in your measured conversion rates, not in a multiplier you invent. Keep the engagement adjustment at 1.0 unless you can publish the reasoning behind a different number.
