Cost per engagement is your fee divided by the engagements a post earned. No publisher reports a cost per engagement benchmark with a stated sample, so this tool compares your result against something that is published: the engagements an Instagram rate of 0.30% implies, the all-industry median in Quid's 2026 Social Media Industry Benchmark Report of 5 March 2026, and 0.48%, the average in Socialinsider's Social Media Benchmarks of 16 January 2026. Both divide by followers. No signup, no card.

Cost per engagement is the fee divided by the engagements earned. There is no modelling in that, just division, which is why it is a fair way to compare a small Instagram creator against a large one. The calculator does the division and then does one more piece of arithmetic that most CPE tools skip, which is working out what your CPE would have been had the post performed at the rates two publishers actually report.
An Instagram account with 100,000 followers produces about 300 engagements per post at Quid's median of 0.30% and about 480 at Socialinsider's average of 0.48%. Divide your fee by each of those and you have two CPE figures with a publisher and a date behind them. Your own CPE is then cheaper than both, dearer than both, or between them. That is a position against published data rather than a score against a threshold.
Running this across every Instagram placement in a campaign tells you which creators delivered more response than the published rates would predict at their size and which delivered less. That is a far better basis for a renewal conversation than a cost per engagement band you cannot trace to anybody.
Cost per engagement takes what you paid for a placement and divides it by the engagements that placement earned. If you paid 1,000 dollars and the post collected 420 likes, comments, saves and shares between them, your cost per engagement is 2.38 dollars. That is the whole calculation and there is nothing hidden inside it.
The reason the metric is worth having is that it prices response rather than audience size. A follower count tells you how many people could have seen a post. Cost per engagement tells you what each person who actually reacted cost you. Those are very different questions and the second one is usually closer to what a brand is paying for.
It also puts creators of wildly different sizes on one footing. A nano account charging 200 dollars and a macro account charging 15,000 dollars cannot be compared on fee alone, and comparing them on follower count tells you nothing about whether either placement worked. Cost per engagement reduces both to the same unit.
The weakness of cost per engagement is the denominator, and it is the same weakness that affects every engagement metric. Engagements is not a single defined quantity. On Instagram a brand might count likes and comments, or likes and comments and saves, or add shares as well. Each choice produces a different engagement total from the same post, and therefore a different cost per engagement from the same fee.
This matters more than it sounds, because the published figures this page compares against each count a specific set. Quid divides total interactions by follower count. Socialinsider, on Instagram, divides the sum of likes and comments by followers and counts nothing else. If your own engagement total includes saves and shares, it is wider than Socialinsider's basis, so your cost per engagement will read lower than a like for like comparison would give.
There is no way to remove that problem, only to state it. Count the same interactions across every placement you compare, write down which ones you counted, and read the published comparison knowing which set each publisher used.

Search for a good Instagram cost per engagement and you will find confident ranges everywhere. Nano creators at one cent to five cents, micro at five to fifteen cents, macro at fifteen to fifty cents, mega above that. Those four bands appear on dozens of pages. Research for this tool checked six of them in detail and not one states a sample size, a collection window or a method.
One of the six does disclose something, and what it discloses undermines the whole set. It gives its method as the post fee divided by followers multiplied by engagement rate. That is not a measurement of what anybody paid. It is arithmetic that starts from an assumed engagement rate and produces a cost per engagement from it. A figure built that way inherits whatever engagement rate was assumed, and if that rate came from the same unsourced tier bands then the cost per engagement is two steps removed from any real observation.
The clearest evidence is in how the numbers travel. The identical four bands appear verbatim across several unrelated sites, one of which is a digital marketing agency blog with no author, no sample and no date on its figures. A number appears on one page with no source, a second page repeats it and credits the first, a third credits the second, and after a few rounds it looks like consensus while having no origin at all.
The Library of Congress maintains a research guide on influencer marketing metrics and costs. It is about as disinterested a source as exists on this subject, since it sells nothing. It names four places to look for cost data. None of the four publishes a cost per engagement figure, and none publishes a cost per thousand impressions figure either. The guide points readers to a formula and a chart as a starting point rather than to a benchmark, because no benchmark is there to point at.
One genuinely sampled cost per engagement figure does exist in the record. A 2017 report analysed 74 campaigns in the United States and reported 24 cents per engagement across all of them. It is dated, the sample is small, and the page that carries it now refuses automated requests, so it could not be read at source for this page. An unverifiable figure is worse than an acknowledged gap, because it looks like evidence, so it is left out.
That is the honest position. No cost per engagement benchmark with a stated sample is available to compare your result against, and this page does not invent one.
Cost per engagement is one division. Nothing on this page is estimated on your behalf and no multiplier is applied to your numbers.
Your result is read against Quid's 0.30% median of 5 March 2026 and Socialinsider's 0.48% average of 16 January 2026, both divided by followers.
Six cost per engagement benchmark pages were checked for this tool. None states a sample size, so none is quoted here as a threshold.
Socialinsider counts likes and comments only on Instagram. If you counted saves and shares too, your engagement number is wider than its basis and the page says so.
Both samples are brand and company accounts. Creators usually engage better at the same size, so the implied CPE is a conservative reference.
When the arithmetic is not enough, the full platform adds audience data and fake-follower scoring across 10M+ creators.
Two publishers do report an Instagram engagement rate, both measured against followers, both with a stated method. They are not cost figures, but cost per engagement is arithmetically determined by an engagement rate, so a published rate can do the work a missing cost benchmark cannot.
Quid's 2026 Social Media Industry Benchmark Report, published 5 March 2026, puts the all-industry Instagram median at 0.30%, down from 0.36% the year before. Its stated formula is that engagement rate is calculated by dividing total interactions by follower count. Its sample is 150 companies drawn at random from each of 18 industries, from a database of over 200,000 companies, covering organic and paid posts.
Socialinsider's Social Media Benchmarks, published 16 January 2026, puts the Instagram average at 0.48% for 2025, down from 0.50% in 2024. Its stated Instagram formula is the sum of likes and comments on the post divided by the total number of followers that page has. Its findings are based on the analysis of 70 million posts from a representative sample of international brands, covering January 2024 to December 2025.
The step from a rate to a cost is one multiplication. An account with 100,000 followers engaging at 0.30% produces 300 engagements per post. Engaging at 0.48% it produces 480. Divide your fee by each of those and you get the cost per engagement each published rate implies at your own account size.
On a 1,000 dollar fee that is 3.33 dollars per engagement at Quid's median and 2.08 dollars at Socialinsider's average. If the post you actually bought earned 420 engagements, your real cost per engagement is 2.38 dollars, which sits below the figure Quid's median implies and above the figure Socialinsider's average implies. The verdict is that it falls between the two published figures, and both are named with their dates on the result.
That is the whole method. It never compares your number against a threshold, because no threshold is published. It compares your number against two published rates, converted into costs using your own follower count and your own fee. Every input to the comparison is either yours or sourced.
One caveat belongs with the arithmetic. Both samples are brand and company accounts rather than individual creators. Creators generally engage better than company pages of a similar size, so the implied cost per engagement from these figures is a conservative reference point. A creator placement that comes in cheaper than both implied figures is doing what you would expect rather than something remarkable. One that comes in dearer than both is a genuine question.

Quid's Instagram median of 0.30% and Socialinsider's average of 0.48% differ by sixty per cent. That is not a contradiction and neither figure is wrong. One reports a median and the other an average, over different windows, from different samples, counting different interactions. A median sits below an average whenever a minority of accounts perform far above the rest, which is exactly what social engagement looks like.
The useful consequence is that two figures bracket your result better than one would. If your cost per engagement beats both, the finding holds whichever statistic you prefer. If it beats one and not the other, that is worth knowing too, and the calculator reports it as between the two rather than picking a side.
What you must not do is average them. A combined figure of 0.39% appears in no publication and is built from two different statistics over two different periods. The same applies to the cost figures they imply.
Reading the Socialinsider page in full turns up more than one Instagram number. Its benchmark table gives 0.48% for 2025 against 0.50% for 2024. Its quarterly section describes Instagram dipping from 0.52% in the first quarter of 2025 to 0.45% in the first and second quarters of 2026. So the same document reports 0.48%, 0.52% and 0.45% depending on which period you read.
This page uses the table figure of 0.48%, because that is the one tied to the stated sample of 70 million posts and the stated window of January 2024 to December 2025. The quarterly readings are part-year figures quoted in prose with no separate sample statement. Both are disclosed here so you can see which was chosen and why, rather than discovering later that the publisher said more than one thing.
A benchmark page that quotes a single number from a source that published several is hiding the most useful information about it, which is how much the number moves.
The direction of travel is also worth more than the level. Quid has Instagram falling from 0.36% to 0.30%. Socialinsider has it falling from 0.50% to 0.48% on the annual table and lower again in its 2026 quarters. Two independent samples agreeing on the direction is a stronger finding than either level, and it means a cost per engagement that holds steady year on year is quietly improving against the market.

Every figure below is reproducible with a calculator, and the tool above produces exactly these results. The implied engagements come from multiplying the follower count by the published rate. The implied cost per engagement comes from dividing the fee by those implied engagements.
Notice what the second and third examples have in common. The fee and the follower count are identical in the first and third, and only the engagements differ. That is the point of the method. It isolates how the post performed from how much it cost, and it does so against rates somebody published rather than against a number invented to make the verdict come out tidy.
In the first example the verdict is neither good nor bad, it is between two published figures. Tools that print a single word like strong or weak have to pick a threshold to do it, and since no cost per engagement threshold is published, that threshold would have to be made up. Reporting the position against each figure separately is less satisfying and more truthful, and it tells you something a single word cannot, which is that the answer depends on whether you prefer a median or an average.

A low cost per engagement is easy to manufacture and hard to interpret. The denominator is engagements, so anything that inflates engagements lowers the cost. Bought likes do it. Engagement pods do it. A giveaway post that asks people to tag three friends does it very effectively, and the comments it collects are worth almost nothing to a brand.
Before treating a cheap cost per engagement as a win, check that the engagement came from a real audience in the right place. A placement at eight cents per engagement from an audience that cannot buy from you is worse value than one at eighty cents from an audience that can. Cost per engagement ranks placements within a campaign well and judges a placement in isolation badly.
Engagement is a reaction, not an outcome. Somebody who liked a post has not visited your site, added anything to a basket or paid for anything. Cost per engagement sits a long way up the funnel and the relationship between it and revenue is weak enough that it should never be the only number on a report.
Read it next to whatever conversion signal you can actually track, next to the audience location and age, and next to an authenticity check on the account. The arithmetic here is reliable. The inference from the arithmetic to whether a partnership worked needs the other evidence.
It also cannot be compared across platforms without care. The same brand running the same creative on Instagram and TikTok will usually see a far lower cost per engagement on TikTok, not because TikTok delivered better value but because published TikTok engagement rates are several times higher. Quid's TikTok median of 2.01% is close to seven times its Instagram median of 0.30%. Comparing a TikTok cost per engagement against an Instagram one and concluding that TikTok is cheaper confuses a platform difference with a performance difference.

"We tested three platforms before landing on Flinque. The creator data is more reliable. The filters actually work. Our team spends half the time finding the right influencers now."
"Flinque replaced two tools we were paying for separately. Creator discovery and performance tracking in one place. And the data is actually accurate."
"Our campaign turnaround time dropped significantly after switching to Flinque. What used to take a full day of research now takes under an hour."
These are the questions people ask about Instagram cost per engagement that no credible source answers as of October 2026. Each one is listed because the alternative is filling it with a number that has no origin.
If you find a page that answers any of these with a confident number, the number almost certainly has no traceable origin. The test is simple and it takes a minute. Look for a sample size, a collection window and a stated formula. If all three are missing, you are reading a figure that circulated rather than one that was measured.
Measure your own cost per engagement the same way on every placement, record which interactions you counted, and build your own baseline over a few campaigns. Your own history is a better benchmark than anybody else's unsourced band, because you know exactly how it was produced. Use the two published rates on this page as an outside reference for whether a given post beat what the market reports, and treat your own numbers as the standard you actually manage against.

The Instagram CPE calculator is free with no signup. When you need audience demographics, fake-follower scoring and discovery across 10M+ creators, the full platform picks up where the arithmetic stops.
Divide what you paid by the engagements the post earned. A 1,000 dollar placement that collected 420 likes, comments, saves and shares works out at 2.38 dollars per engagement. The arithmetic is simple and the judgement call is which interactions you count, since adding saves and shares to likes and comments raises the engagement total and lowers the cost per engagement from the same fee. Count the same set on every placement you compare and record which set it was.
No publisher reports a cost per engagement benchmark with a stated sample, so there is no good figure to quote. Six benchmark pages were checked for this tool and none states a sample size, a window or a method. One discloses that its figures are derived as the post fee divided by followers multiplied by engagement rate, which means they are arithmetic from an assumed rate rather than observed cost. Instead of a band, this page compares your result against the cost per engagement that two published Instagram rates imply at your own follower count. Quid's 2026 Social Media Industry Benchmark Report, published 5 March 2026, gives an all-industry median of 0.30% on followers. Socialinsider's Social Media Benchmarks, published 16 January 2026, gives an average of 0.48%. At a 1,000 dollar fee and 100,000 followers those imply 3.33 dollars and 2.08 dollars per engagement.
Because the two published figures it compares against are engagement rates measured against followers, and a rate only becomes a cost once you know how many followers it applies to. An account with 100,000 followers engaging at Socialinsider's 0.48% average produces 480 engagements, so a 1,000 dollar fee implies 2.08 dollars per engagement. Without the follower count there is no way to turn a published rate into a published cost, and the tool would have to compare your number against a threshold nobody has published.
Mostly because published Instagram engagement rates are much lower. Quid's 2026 report of 5 March 2026 puts the Instagram median at 0.30% and the TikTok median at 2.01%, close to seven times higher. Socialinsider's 16 January 2026 benchmarks put Instagram at 0.48% and TikTok at 3.70% for 2025. Since cost per engagement is the fee divided by engagements, a platform where the same audience size produces several times more engagements will produce a much lower cost per engagement from the same fee. That is a platform difference rather than evidence that TikTok placements are better value, and comparing the two numbers directly is a common mistake.
They can, and whether you include them changes the answer. Quid's stated formula divides total interactions by follower count, which is a wide definition. Socialinsider's stated Instagram formula is narrower, the sum of likes and comments divided by followers, counting nothing else. So if you include saves and shares in your own engagement total, your figure is wider than Socialinsider's basis and your cost per engagement will read lower than a matched comparison would give. The tool cannot detect which interactions you counted, so it states the difference rather than adjusting for it.
