How to Calculate Engagement Rate on Social Media

Engagement rate (ER) is a fundamental metric used to measure the level of interaction that social media content receives relative to audience size. Unlike follower counts, which are often considered "vanity metrics," engagement rate provides deep insight into how well your content actually resonates with your community.

The Standard Engagement Rate Formula

The most common way to calculate engagement is by dividing total interactions by your total number of followers (or reach) and multiplying by 100 to get a percentage:

ER = (Total Likes + Comments + Shares + Saves) / (Total Followers or Reach) x 100

ER by Reach vs. ER by Followers

There are two primary methods used by social media managers:

• Engagement Rate by Followers (ERR): This is the most common metric. It tells you what percentage of your total audience interacted with a specific post.
• Engagement Rate by Reach (ERR): This is often considered more accurate for individual post performance because it measures interactions against the people who actually saw the post, rather than just those who follow you.

Practical Example

Imagine you have an Instagram account with 10,000 followers. You post a photo that receives:

• 250 Likes
• 35 Comments
• 15 Shares
• 50 Saves

Your total interactions are 350 (250+35+15+50). Dividing 350 by 10,000 gives 0.035. Multiply by 100, and your Engagement Rate is 3.5%.

What is a Good Engagement Rate?

Benchmarks vary significantly by platform and industry. However, general industry standards suggest:

Platform	Average ER	High ER
Instagram	1% – 3%	5%+
TikTok	4% – 15%	18%+
Facebook	0.1% – 0.5%	1%+
LinkedIn	1% – 2%	4%+

Tips to Improve Your Social Media Engagement

1. Post when your audience is active: Use platform analytics to find peak hours.
2. Ask questions: End your captions with a Call to Action (CTA) that encourages comments.
3. Use Video: Reels, TikToks, and Shorts generally receive higher reach and engagement than static images.
4. Reply to comments: Engagement is a two-way street; interacting with your followers signals the algorithm to show your content to more people.
