How to Calculate Engagement Rate of a Post
Engagement rate is the ultimate metric for social media success. Unlike "vanity metrics" like follower counts, engagement rate tells you how many people actually care about your content. It measures the level of interaction—likes, comments, shares, and saves—relative to the number of people who saw the post.
The Engagement Rate Formula
There are two primary ways to calculate engagement rate for an individual post. This calculator uses the Engagement by Reach method, as it is the most accurate reflection of how well a specific post performed among those who actually saw it.
Formula:
Engagement Rate = ((Total Interactions) / Total Reach) x 100
Where "Total Interactions" equals the sum of Likes + Comments + Shares + Saves.
Why Reach is Better Than Followers
Calculating engagement based on your follower count can be misleading. Algorithms often only show your post to 10% of your followers. If you have 10,000 followers but only 1,000 saw the post, dividing your likes by 10,000 makes your content look less successful than it actually was. Using Reach (the number of unique users who saw the post) provides a "purer" view of content quality.
Realistic Example
Imagine you posted a photo on Instagram. Here are the stats:
- Likes: 150
- Comments: 20
- Shares: 5
- Saves: 25
- Total Reach: 2,000 people
Calculation: (150 + 20 + 5 + 25) = 200 total interactions.
(200 / 2,000) = 0.10.
0.10 x 100 = 10% Engagement Rate.
What is a Good Engagement Rate?
| Rate | Classification |
|---|---|
| Less than 1% | Low Engagement |
| 1% – 3% | Average / Good |
| 3% – 5% | High Engagement |
| Above 5% | Very High (Viral Potential) |
Frequently Asked Questions
Q: Should I include Saves in my calculation?
A: Yes. On platforms like Instagram and LinkedIn, saves are a high-intent signal that the user found your content valuable enough to revisit, which the algorithm rewards heavily.
Q: Is engagement rate the same for every platform?
A: No. TikTok usually sees much higher engagement rates (often 5-10%) compared to Facebook (often below 1%) because of how the "For You" page functions.
