💡 What is Engagement Rate?

Engagement Rate (ER) measures how actively your audience interacts with your content. It is calculated as total engagements divided by followers (or reach) × 100.

A high ER means your content resonates — even a small account with high ER is more valuable to brands than a large account with low ER.

Engagement Rate Formulas Explained

ER by Followers = (Total Engagements ÷ Followers) × 100. The most common formula, useful for comparing accounts of different sizes. ER by Reach = (Engagements ÷ Reach) × 100. More accurate for paid/boosted posts where organic reach differs from follower count. ER by Impressions = (Engagements ÷ Impressions) × 100. Useful for measuring content efficiency across total views including repeat viewers.

Frequently Asked Questions

What is a good engagement rate on Instagram?

A good Instagram engagement rate is typically 1–3% for larger accounts (100K+ followers) and 3–6% for mid-size accounts (10K–100K). Micro-influencers (1K–10K) often see 6–10%. Anything above 6% is considered excellent.

What counts as an engagement on social media?

Engagements include likes, comments, shares, saves (Instagram), retweets (Twitter), reactions (LinkedIn/Facebook). Our calculator includes all four: likes, comments, shares, and saves.

Why is my engagement rate dropping?

Common causes: posting too frequently or infrequently, content not matching audience interests, wrong posting times, algorithm changes, or follower growth outpacing engagement growth. Experiment with content formats and posting times.

How do brands evaluate influencer engagement rate?

Brands evaluate influencers by ER rather than follower count alone. An account with 10K followers and 8% ER is typically more valuable than one with 100K and 0.5% ER. A minimum 2–3% ER is usually expected for paid collaborations.
