Measure

Engagement rate calculator

Engagement rate by reach, by impressions and by follower count — with the benchmark each one should be judged against.

Engagement rate is three different numbers depending on what you divide by, and comparing the wrong one to a published benchmark is how people conclude their account is failing when it is not.

Enter your post metrics once and get all three: engagement rate by reach (the honest one for a single post), by impressions (the conservative one), and by followers (the one brands and media kits use). Each comes with a plain-language read on where it sits.

How to use it

  1. Enter likes, comments, shares and saves. Saves and shares matter more than likes to every current ranking system — count them.
  2. Add reach or impressions if you have them, and your follower count.
  3. Read the rate that matches your question: reach for "did this post work", followers for "what do I put in a media kit".
  4. Compare posts against your own median, not against a benchmark from a different account size or niche.

Tips that actually change results

  • Smaller accounts almost always show higher engagement rates. A 6% rate at 800 followers is not comparable to 1.5% at 200,000.
  • Track the median of your last 20 posts, not the average. One viral post distorts an average badly.
  • If reach is high and engagement is low, the hook worked and the content did not.
  • If engagement is high and reach is low, the content worked and the platform has not distributed it yet. Do not delete it.
FAQ

Questions about this tool

How do you calculate engagement rate?

Add your interactions — likes, comments, shares and saves — then divide by your chosen denominator and multiply by 100. Engagement rate by reach divides by accounts reached; by impressions divides by total impressions; by followers divides by follower count.

Which engagement rate should I use?

Use engagement rate by reach to judge a single post, because it measures response among people who actually saw it. Use engagement rate by followers for media kits and brand conversations, because that is the figure brands compare across accounts.

What is a good engagement rate?

It depends heavily on account size and platform. As a rough guide by followers: above 3% is strong for accounts under 10,000, while 1–2% is normal above 100,000. Judge yourself against your own median first.

Do saves and shares count as engagement?

Yes, and they carry more weight than likes in current ranking systems, because they signal value rather than approval. Include them.
