Influencer Marketing Calculations

Influencer Marketing Calculations

Let’s start by demystifying some common influencer marketing metrics and formulas:

Engagement Rate

Engagement rate measures the percentage of followers that actively interact with the influencer’s content. To calculate:

Engagement Rate = (Likes + Comments) / Followers x 100

Higher engagement rates indicate better connection and trust between an influencer and their audience.

Impression Rate

Impression rate shows the percentage of followers who saw a post. To calculate:

Impression Rate = Impressions / Followers x 100

More impressions expand reach but engagement also matters.

Cost per Acquisition (CPA)

CPA measures the cost of acquiring a lead, sale or other goal through influencer marketing. To calculate:

CPA = Total Campaign Cost / Total Conversions

Lower CPAs represent higher influencer ROI.

Return on Investment (ROI)

ROI indicates the revenue generated per dollar spent on influencer marketing. To calculate:

ROI = Revenue Gained / Total Campaign Cost x 100

Higher ROI is better. Look for 5-10X+ multiplier from influencer content.

These metrics allow you to quantify influencer marketing performance and make data-driven decisions on budget and strategy.
