Engagement Rate
Engagement rate is the percentage of an audience that interacts with social media content out of those who saw or follow the account. It measures how compelling a post is relative to its audience size, not its absolute volume of likes or comments. Marketers use engagement rate to compare creative performance, benchmark against competitors, and evaluate the audience quality of influencers and creators.
The Engagement Rate Formulas
There is no single engagement rate formula. The four most common variations divide engagements by a different denominator depending on what the marketer is measuring:
Engagement Rate by Followers (ER per post)
ER = (Total Engagements / Total Followers) × 100
Engagement Rate by Reach
ER = (Total Engagements / Reach) × 100
Engagement Rate by Impressions
ER = (Total Engagements / Impressions) × 100
Daily Engagement Rate
Daily ER = (Total Engagements / Followers) / Number of Days × 100
Use ER by reach when measuring content quality, since it ignores follower count bloat from inactive accounts. Use ER by followers when benchmarking against competitor accounts, since reach data is rarely public. Use ER by impressions when running paid promotions, where impressions inflate beyond organic reach.
A post with 800 engagements on an Instagram account with 20,000 followers has an ER by followers of 4%. The same post reaching 12,000 unique users has an ER by reach of 6.67%.
What Is a Good Engagement Rate?
A good engagement rate depends entirely on the platform, audience size, and industry. Compare to the platform median, not to a universal target. Smaller accounts almost always show higher engagement rates than large accounts, so percentile benchmarks matter more than raw averages.
| Platform | Median ER (per post) | Source |
|---|---|---|
| 0.50% | Rival IQ 2024 | |
| TikTok | 2.63% | Rival IQ 2024 |
| 0.063% | Rival IQ 2024 | |
| Twitter/X | 0.029% | Rival IQ 2024 |
| LinkedIn (company pages) | 1.80% | LinkedIn 2024 benchmarks |
On Instagram, anything above 1% is considered above average and above 3% is strong. TikTok averages 2.63% across industries, down from 5% to 9% in 2021 to 2022 as the platform scaled. LinkedIn varies sharply by industry, with B2B SaaS and education accounts often hitting 3% or higher. Influencer benchmarks differ: micro-influencers (under 50,000 followers) average 3.86% on Instagram per HypeAuditor, while accounts above 1 million average closer to 1.21%.
linkutm’s social engagement rate calculator computes ER from engagements and followers (or reach, or impressions) and returns the result as a percentage.
What Counts as an Engagement
Each platform counts different interactions as engagements, which is why cross-platform comparison is unreliable.
- Instagram: likes, comments, shares, saves
- TikTok: likes, comments, shares, saves, video completion rate (in some calculations)
- Facebook: reactions, comments, shares, post clicks
- LinkedIn: reactions, comments, shares, clicks
- Twitter/X: replies, retweets, likes, bookmarks, profile clicks, link clicks
Saves and shares signal stronger intent than likes and carry more weight in modern platform algorithms. Instagram’s algorithm specifically prioritizes saves and sends-to-friends as quality signals. Always confirm which interactions a third-party tool includes before comparing engagement rates from different sources.
Common Engagement Rate Mistakes
Comparing across platforms. Twitter’s median ER is 0.029% and TikTok’s is 2.63%. Cross-platform ER comparisons reveal nothing useful about creative performance.
Using ER by followers across account sizes. A 5,000-follower account at 8% ER and a 500,000-follower account at 1.5% ER may have similar absolute engagement volume. Smaller accounts compound a higher ratio with smaller denominators.
Treating likes as the headline metric. Saves and shares signal that the content is useful enough to revisit or share. Algorithm reach, especially on Instagram and LinkedIn, weights these heavier than likes.
Ignoring algorithm shifts. Instagram’s late-2022 reach changes, which prioritized Reels over feed posts, dropped baseline organic reach across most accounts. Comparing 2022 ER to 2024 ER without context is misleading.
Forgetting paid amplification. Boosted posts inflate impressions without proportional engagement, depressing ER. Filter out paid posts before benchmarking organic creative performance.
Frequently Asked Questions
What is engagement rate?
Engagement rate is the percentage of an audience that interacts with social media content. It is calculated by dividing total engagements (likes, comments, shares, saves) by an audience metric (followers, reach, or impressions) and multiplying by 100. The metric indicates how compelling a piece of content is to its audience relative to size.
How do you calculate engagement rate?
The most common formula is: ER = (Total Engagements / Total Followers) × 100. A post with 500 engagements on an account with 10,000 followers has an ER of 5%. There are also variants that divide by reach or impressions instead of followers, used for comparing posts of different reach sizes or comparing organic to paid performance.
What is a good engagement rate on social media?
A good engagement rate depends on the platform. Instagram averages 0.50% per post (Rival IQ 2024), with above 1% considered strong. TikTok averages 2.63%. LinkedIn company pages average 1.80%. Facebook and Twitter/X both average below 0.1%. Compare to the platform median for the audience size, not to a universal target.
What is the difference between engagement rate by reach and engagement rate by followers?
ER by reach divides engagements by the number of unique users who saw the post; ER by followers divides by total followers. ER by reach measures content quality more accurately, since it isolates the audience that actually saw the post. ER by followers is useful for cross-account benchmarking when reach data is not public.
Why is engagement rate dropping on Instagram?
Instagram’s organic reach has declined since the late-2022 algorithm changes that prioritized Reels over static feed posts. Lower reach reduces the engagement numerator while follower counts continue to grow, dropping the ratio. Posting Reels, using carousels, and creating saveable content (infographics, how-to slides) typically reverses the trend.
