Overview

Use this Influencer Cost Per Engagement Calculator to estimate how much you may pay for each interaction on an influencer campaign. Enter the campaign cost, expected impressions, engagement rate, and any extra costs to compare partnerships more consistently.

How it works

The calculator first adds the influencer fee and extra costs to get total campaign cost. It then estimates engagements by multiplying impressions by the engagement rate. Cost per engagement is calculated by dividing total cost by estimated engagements. It also shows CPM by dividing total cost by impressions in thousands, which helps you compare engagement efficiency and reach cost together.
