How to Calculate Your Instagram Engagement Rate
Understanding your Instagram Engagement Rate is crucial for evaluating the performance of your content and the health of your account. Unlike vanity metrics such as follower count, engagement rate measures how actively involved your audience is with your content.
Why is Engagement Rate Important?
For influencers, brands, and marketers, the engagement rate is the primary metric used to determine the return on investment (ROI) of social media campaigns. A high follower count with low engagement suggests inactive followers or irrelevant content, whereas a smaller account with high engagement signifies a loyal and active community.
The Formula Used
This calculator uses the standard public engagement rate formula based on followers. This is the most common method used by marketing agencies to vet influencers.
While Likes and Comments are public metrics, Saves and Shares are private analytics. If you have access to your insights, including them will give you a more accurate "True Engagement" score. If you are analyzing a competitor or another influencer, you typically stick to Likes and Comments.
What is a Good Engagement Rate?
Engagement rates vary significantly depending on the industry and the size of the audience. Generally, as follower counts grow, engagement rates tend to dip slightly.
Less than 1%: Considered low. This may indicate ghost followers or content that isn't resonating.
1% – 3.5%: The industry average. This is a healthy range for most accounts.
3.5% – 6%: High engagement. This indicates a strong connection with the audience.
Above 6%: Very high engagement. Often seen in micro-influencers or viral posts.
How to Improve Your Rate
To boost your numbers, focus on creating high-quality, shareable content. utilize Instagram Stories and Stickers to encourage interaction, reply to every comment to double your comment count, and post at times when your audience is most active.
