Earned media value (EMV) is an estimate of what a piece of unpaid coverage would have cost to buy as advertising. In influencer marketing it converts a campaign’s impressions, or sometimes its likes and comments, into a dollar figure by applying an assumed ad rate and, often, a multiplier. It is a proxy for media cost, calculated after the fact.

The short answer: EMV is a rough comparison number, not revenue, and its parent metric has been ruled invalid by the global body that sets measurement standards. Use it to compare like against like inside your own reporting, and never put it next to your P&L.

Key Takeaways

  • EMV = (impressions / 1,000) x CPM x any multiplier. Every input is an assumption you choose, so the output is an assumption too.
  • The same 1.5 million impression campaign can honestly be reported as A$15,000 or A$75,000 depending on the CPM and multiplier applied.
  • AMEC’s Barcelona Principles 4.0, June 2025, Principle 5: “Invalid measures such as advertising value equivalents (AVEs) should not be used. Instead measure and evaluate the contribution of communication by its outcome and impact.”
  • There is no agreed methodology behind EMV, so two agencies will report different numbers for the same campaign and both will be defensible.
  • Australian brands spent A$830 million on influencer marketing in the last twelve months, so the reporting standard you accept has real money behind it.

What Is Earned Media Value, and Where Did It Come From?

Earned media value is influencer marketing’s version of advertising value equivalency (AVE), a public relations metric from the era of press clippings. The original logic: measure the column inches a story occupied, look up what an ad of that size would have cost in the same publication, and report that figure as the value of the coverage. Social media inherited the idea and swapped column inches for impressions.

The inheritance is the problem. AVE has been rejected by every serious measurement body that has examined it. The Institute for Public Relations is direct: “The Commission for PR Measurement & Evaluation does not endorse Ad Value Equivalency (AVE) as a measurement tool.” That position dates to a 2003 paper by Bruce Jeffries-Fox and has not softened since.

AMEC, the international body behind the Barcelona Principles, applies four questions to any metric in its Principle 5 guidance: Is it valid? Is it endorsed by the industry? Does it help us make informed decisions? Does it assist in evaluating, improving, and learning? AVEs do not pass those tests, in AMEC’s own words.

None of that has stopped EMV appearing in campaign reports, because it answers a real need. A brand marketer who has just spent A$40,000 on twelve creators wants one number to describe what came back. EMV gives them one. The honest position is that the number describes notional media cost and nothing else.

How Do You Calculate Earned Media Value?

The standard formula is short:

EMV = (impressions / 1,000) x CPM x any multiplier

Impressions come from platform analytics. The CPM is an assumed rate, usually pulled from what the brand pays for comparable paid social. The multiplier is a number someone picked to represent the idea that earned coverage is worth more than bought coverage.

Here is a campaign of 12 micro-creators delivering 1,500,000 total impressions. The only thing changing across the rows is the CPM assumption, taken from your own media plan.

CPM assumption (A$)Base EMV (A$)With a 2x engagement multiplier (A$)
1015,00030,000
1827,00054,000
2537,50075,000

The same campaign, the same delivered impressions, reported anywhere from A$15,000 to A$75,000. That is a fivefold spread, and no one in that range has lied. This is the whole reason EMV cannot be treated as revenue.

The engagement-based variant works differently. Instead of impressions, you assign a dollar value to each like, comment, share and view, then sum them. It moves when engagement rates move, which changes the ranking of your creators. Measured per follower, engagement drops hard from nano to micro and then sits near 1 percent at every size above that. Measured per view, it holds close to 4 percent across every tier (Buffer, 27 million Instagram posts). Run an impression-based EMV and the big accounts win. Run an engagement-based one and the small accounts win. Same campaign, opposite conclusion.

Why Do Two Agencies Report Different EMV for the Same Campaign?

Because there is no standard, and there never has been. AMEC’s “22 Reasons to Say No to AVEs”, written by then chairman Richard Bagnall in 2017, makes the point twice over.

Reason 16 covers methodology: each provider has its own, and each is likely to use different advertising rates, so the metric is not transferable between suppliers. You cannot benchmark your agency’s EMV against another agency’s EMV, or against a case study you read online.

Reason 15 covers the multiplier: “there is no credible, peer-reviewed research that proves that any multiplier (or divider for that matter) should be used, or even whether one is relevant and appropriate at all. Where multipliers have been used, different organisations have used different multipliers, thus further confusing the market.”

So if an agency shows you an EMV with a 3x or 4x multiplier baked in, ask where the multiplier came from. There is no correct answer, only a disclosed one. An agency that shows you the base figure, states its CPM assumption, and explains any multiplier separately is being straight with you. One that hands over a single large number with no inputs is not.

The deeper issue, Reason 5, is that AVEs confuse cost with value. Cost and value often bear no relation to each other. What an ad slot would have cost tells you nothing about whether anyone changed their mind, remembered your brand, or bought anything.

What Is EMV Genuinely Useful For, and What Must It Never Be Used For?

EMV has one legitimate job: comparing like against like, inside your own reporting, with your inputs held constant. If you use the same CPM and the same multiplier every time, EMV becomes a normalised way to compare this quarter’s creator mix against last quarter’s, or one content format against another. That is a directional signal, and it is worth having.

What it must never do is stand in for financial performance. EMV is not ROI, and the two get conflated constantly. ROI compares what you spent against what you earned, and it needs attribution, margin and real revenue behind it. Our guide to measuring influencer marketing ROI covers that method properly. EMV compares what you spent against a hypothetical ad buy you never made.

Three further limits are worth knowing. AVEs take no account of target audiences (Reason 11): they reward mass-reach outlets with higher ad rates, so a precisely targeted campaign hitting exactly the right 40,000 people can score a small EMV while a scattershot one scores large. They take no account of coverage quality (Reason 9): every mention counts equally, positive, neutral or damaging. And what you measure is what you get (Reason 12), so a team held to EMV will start chasing volume instead of fit.

Finally, EMV is an output metric only (Reason 19). Good evaluation moves past outputs to outtakes, outcomes and business impact. EMV tells you something happened. It cannot tell you what it did.

What Belongs in a Campaign Report Alongside EMV?

A report that can survive a finance review has four layers, and EMV sits in the first one.

Start with delivery: assets produced, creators activated, posts live, on time or not. Then outputs: impressions, reach, engagement rate by creator and by format, saves and shares. This is where EMV belongs, clearly labelled as an estimate with its CPM and multiplier shown.

Then outtakes: what people did with the content. Comment sentiment, question volume, DMs to the brand, branded search lift, direct traffic in the 72 hours after a post.

Then outcomes: tracked clicks, code redemptions, landing page conversions, revenue attributed through your own analytics, cost per acquisition against your other channels. The BIG Live Gatsby premieres we ran returned 6:1 on tracked outcomes. That is an attributed outcome figure, not EMV, and it is the kind worth defending in a budget meeting.

Ask for creator-level data at every layer. Aggregate reporting hides which three creators carried the campaign, and that is the single most useful thing you learn from a run. It is a standing part of how we structure campaign management reporting.

Frequently Asked Questions

Is earned media value the same as ROI?

No. ROI measures money in against money out. EMV estimates what your unpaid coverage would have cost to buy as advertising, using a CPM you chose and often a multiplier no research supports. AMEC’s Reason 5 puts it plainly: AVEs confuse cost with value, and the two often bear no relation to each other. A campaign can post a large EMV and lose money. Report both if you like, but never present EMV as return.

What is a good EMV for a campaign?

There is no benchmark, and anyone offering one is guessing. Because each provider uses its own advertising rates and its own multiplier (AMEC, Reason 16), EMV figures are not transferable between suppliers. Our worked example shows the same 1.5 million impression campaign landing anywhere from A$15,000 to A$75,000 on honest inputs. The only comparison that means anything is your own campaigns against each other, with the CPM and multiplier held constant.

Should I ask my agency for EMV?

Ask for it if you want a consistent output metric, but ask for the inputs with it: the impression source, the CPM assumption, and any multiplier with its justification. Then ask for the outcome layer separately, tracked clicks, conversions and attributed revenue. AMEC’s Reason 19 is why: AVEs are an output metric only, and good evaluation moves to outtakes, outcomes and business impact.

Why does EMV rank my creators differently depending on the formula?

Because impression-based and engagement-based EMV measure different things, and so does the engagement rate you feed into them. Per follower, small accounts look far stronger than large ones. Per view, the tiers sit close together. An impression-based calculation favours the big accounts, an engagement-based one favours the small ones, and switching the denominator moves the answer again. Our engagement rate calculator shows both denominators side by side for any creator, which is the quickest way to see how much the choice moves. Pick one method, state it, and keep it fixed, or your creator rankings will flip every time the formula changes.

Does anyone still consider EMV a valid metric?

Not the standards bodies. AMEC’s Barcelona Principles 4.0, released June 2025, states that invalid measures such as AVEs should not be used, and the Institute for Public Relations has declined to endorse AVE since 2003. Plenty of brands and agencies still report EMV anyway, which is fine as long as everyone in the room knows it is an estimate of notional media cost rather than a business result.

Getting a Number You Can Take to Your CFO

EMV survives because reporting needs a headline figure and impressions alone feel thin. That is a fair need. The fix is not to ban the number, it is to label it: show the CPM, show the multiplier, call it an estimate, and put the outcome metrics underneath it where the actual argument gets made.

Australian brands put A$830 million into influencer marketing over the past twelve months, up 13.5 percent year on year, and the market is on track to pass A$1 billion during 2026. More detail sits in our breakdown of Australian influencer marketing statistics. At that scale, the reporting standard your agency sets is worth interrogating before you sign, not after the recap deck arrives.

If you want a price rather than a valuation, our influencer rate calculator works from a creator’s actual views and engagement and shows what each part of a post is worth. And if you want to see what creator-level reporting looks like with the outcome layer attached, we are happy to walk you through a recent one.
