How to Calculate Social Media Engagement Rate

Social media engagement rate is a critical metric used to measure how much your audience interacts with your content. Unlike simple follower counts, which can be inflated by "ghost" followers, the engagement rate proves how much value your audience finds in your posts.

The Core Formula

While there are several ways to calculate this, the most common formula used by digital marketers is:

Engagement Rate = [(Likes + Comments + Shares + Saves) / Total Followers] x 100

Engagement Rate by Reach (ERR) vs. By Followers

Depending on your goals, you may choose different denominators:

  • By Followers: Most common for public benchmarking against competitors. It shows what percentage of your total community is active.
  • By Reach: More accurate for measuring content quality. It calculates engagement based on people who actually saw the post, excluding those the algorithm didn't show the post to.

What is a Good Engagement Rate?

Engagement rates vary significantly by platform. Here are the general 2024 benchmarks for "Good" performance:

Platform Average Rate Good Rate
Instagram 0.60% – 0.90% 2% +
Facebook 0.06% – 0.15% 0.50% +
TikTok 4.25% – 6.00% 10% +
Twitter (X) 0.04% – 0.08% 0.20% +

Example Calculation

Imagine you have 5,000 followers. You post a photo that receives:

  • 120 Likes
  • 15 Comments
  • 5 Shares
  • 10 Saves

Step 1: Add interactions: 120 + 15 + 5 + 10 = 150 total interactions.

Step 2: Divide by followers: 150 / 5,000 = 0.03.

Step 3: Multiply by 100 = 3.00% Engagement Rate.

document.getElementById('calcMethod').onchange = function() { var method = this.value; var label = document.getElementById('baseLabel'); if (method === 'reach') { label.innerText = 'Total Reach / Impressions'; } else { label.innerText = 'Total Followers'; } }; function calculateEngagement() { var baseCount = parseFloat(document.getElementById('baseCount').value); var likes = parseFloat(document.getElementById('likesCount').value) || 0; var comments = parseFloat(document.getElementById('commentsCount').value) || 0; var shares = parseFloat(document.getElementById('sharesCount').value) || 0; var saves = parseFloat(document.getElementById('savesCount').value) || 0; var resultArea = document.getElementById('resultArea'); var resultVal = document.getElementById('engagementValue'); var benchmarkNote = document.getElementById('benchmarkNote'); if (!baseCount || baseCount <= 0) { alert('Please enter a valid number for Followers or Reach.'); return; } var totalInteractions = likes + comments + shares + saves; var rate = (totalInteractions / baseCount) * 100; resultVal.innerText = rate.toFixed(2) + '%'; resultArea.style.display = 'block'; var note = ""; if (rate = 1 && rate = 3 && rate < 6) { note = "High engagement! Your audience is very responsive to this content."; } else { note = "Viral level engagement! This content is performing exceptionally well."; } benchmarkNote.innerText = note; }
