Engagement Rate Calculator

Measure how engaged your audience really is. Works for Instagram, TikTok, YouTube, X and Facebook — by followers or by reach.

How to use this engagement rate calculator

Pick whether you want to measure engagement against your follower count (the standard public metric) or against your actual reach/views (a truer measure of content performance). Enter the total likes and comments across the posts you’re measuring, add saves and shares if you have them, and hit calculate.

The formula

Engagement rate = (total interactions ÷ audience ÷ posts) × 100. Using reach instead of followers usually produces a higher, more flattering number — so always compare like-for-like.

Frequently asked questions

What is a good engagement rate?
As a rough guide on Instagram: under 1% is low, 1–3.5% is average, 3.5–6% is high, and above 6% is excellent. Smaller accounts (under 10k) usually see higher rates than large ones.
How is engagement rate calculated?
The most common formula is (total interactions ÷ followers) × 100, where interactions are likes + comments (and optionally saves and shares). This tool also offers engagement-by-reach if you know your average reach.
Why does engagement rate matter more than follower count?
Brands and algorithms reward accounts whose audiences actually interact. A 5% engagement rate on 10k followers often beats 0.5% on 100k for reach, trust and sponsorship value.
Does buying followers hurt my engagement rate?
Yes. Inactive or fake followers inflate your denominator without adding interactions, which drags your rate down and can reduce algorithmic reach. Focus on real, relevant growth.
