Enter the fee and the engagements earned to get cost per engagement instantly. There is no modelling here, just the arithmetic, which makes it the cleanest way to compare a nano placement against a macro one on the same footing.
The result is placed against reported CPE bands by tier so the figure means something. Nano is reported at about $0.01 to $0.05, micro at about $0.05 to $0.15 and macro at about $0.15 to $0.50 per engagement.
Running CPE across a campaign shows which partnerships bought real response and which simply bought reach. That is the evidence you need when deciding who to book again.
Two numbers and a click gives you CPE. No account, no setup and no waiting.
Your result is compared against reported tier bands rather than left without context.
CPE is pure arithmetic, so nothing here is modelled or estimated on your behalf.
Engagement tells you who reacted, which is usually a better guide than impressions alone.

"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."
The influencer 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 maths stops.
CPE divides what you paid by the total engagements the content earned. Engagements normally mean likes, comments, shares and saves added together. A $1,500 post that earned 12,000 engagements works out at $0.125 per engagement. It is pure arithmetic with no modelling behind it, which makes CPE a fair way to compare a small creator against a large one, since it prices response rather than audience size.
Reported CPE benchmarks vary by creator tier. Nano creators are reported at roughly $0.01 to $0.05 per engagement, micro creators at roughly $0.05 to $0.15 and macro creators at roughly $0.15 to $0.50. Smaller creators tend to deliver cheaper engagement because their audiences respond at higher rates. Landing inside the reported band for the size of creator you booked is a reasonable outcome and landing under it suggests the placement worked hard for you.
Because engagement rate falls as an account grows. Reported engagement rates run at roughly 5% to 10% for nano accounts, 3% to 6% for micro, 1.5% to 4% for mid tier, 1% to 2.5% for macro and 0.5% to 1.5% for mega accounts. A nano creator charges far less per post while a much larger share of their audience responds, so the cost of each individual interaction lands lower. Reported blended figures put micro creators at about $0.20 per engagement against about $0.33 for macro creators, which is the same efficiency gap.
CPE prices response while CPM prices reach. CPM is the cost per 1,000 impressions, reported at roughly $5 to $15 on Instagram, $3 to $10 on TikTok and $10 to $30 on YouTube. CPE tells you what each like, comment, share or save actually cost. Large accounts usually win on CPM because reach is cheap at scale and small accounts usually win on CPE because their audiences actually react. Reading both together stops you buying a large impression number that nobody engaged with.
Yes, it is free with no signup and no card. The maths runs in your browser, so nothing you enter is sent anywhere. It sits alongside the other free tools including the CPM calculator and the engagement rate calculator. When you need more than a single calculation, the full platform adds audience demographics and fake-follower scoring across more than 10 million verified creators, starting at $0 with no card.
Not on its own. A very low CPE looks efficient, though it means nothing if the engagements came from an audience that will never buy from you or from followers that are not real. Check the engagement is coming from a genuine audience before you treat a cheap CPE as a win. Read it next to audience authenticity, audience location and whatever conversion signal you can track, then judge the placement on the full picture rather than on one number.
