How to Calculate Engagement Rate on Instagram Reels

Unlike standard feed posts, Instagram Reels prioritize "discoverability" through the algorithm. While vanity metrics like views are exciting, the true measure of a Reel's success is its Engagement Rate (ER). This metric tells you what percentage of people who saw your video actually took an action.

The Standard Reels Engagement Formula

The most accurate way to calculate engagement for Reels is to sum all active interactions and divide them by your reach or views. Here is the math:

ER % = [(Likes + Comments + Shares + Saves) ÷ Reach] × 100

Which Metric Should You Use as the Base?

Depending on your goals, you might choose different denominators for your calculation:

  • ER by Reach: This is the most accurate industry standard. It measures how many unique people interacted with your Reel.
  • ER by Views (Plays): Useful for understanding the "stickiness" of your content. Since one person can view a Reel multiple times, this number is usually lower than ER by Reach.
  • ER by Followers: Best for measuring how your loyal community responds to your content, though it doesn't account for the viral potential of Reels hitting the Explore page.

Practical Example

Let's say your latest Instagram Reel has the following stats:

  • Likes: 500
  • Comments: 25
  • Shares: 40
  • Saves: 35
  • Reach: 10,000

First, add the interactions: 500 + 25 + 40 + 35 = 600 total interactions.
Then, divide by reach: 600 / 10,000 = 0.06.
Finally, multiply by 100 to get 6.00% Engagement Rate.

What is a "Good" Engagement Rate for Reels?

Engagement rates on Reels are typically higher than traditional feed posts. While it varies by industry, here are general benchmarks for Reel engagement based on Reach:

Performance Level Engagement Rate (by Reach)
Average 2% – 4%
Above Average 4% – 7%
Excellent (Viral Potential) 8% +

3 Tips to Increase Your Reels Engagement

  1. The First 3 Seconds: Use a strong visual or text "hook" to prevent users from scrolling past.
  2. Encourage Saves: Create educational content (like a recipe or tutorial) that users will want to save for later reference.
  3. Reply to Comments: Instagram's algorithm rewards posts with high conversation. Replying to comments in the first hour can boost the Reel's visibility significantly.
