📐 Instagram Engagement Rate Formula Explained

The most common formula calculates engagement relative to your total followers:

$$\text{Engagement Rate} = \left( \frac{\text{Likes + Comments + Shares + Saves}}{\text{Total Followers}} \right) \times 100$$

 

✅ Step-by-Step Example:

Let’s calculate engagement rate for a post with:

• Likes: 180
• Comments: 35
• Shares: 15
• Saves: 25
• Followers: 3,500

Engagement Rate (ER) =
(180 + 35 + 15 + 25) ÷ 3,500 × 100
= 255 ÷ 3,500 × 100
= 7.29%
