Calculate social media engagement rate by followers,
reach, or impressions. Enter your engagement numbers and get an instant
result, plus general benchmark ranges to see how it compares.
Quick answer: Engagement rate = (Total Engagements ÷ Followers,
Reach, or Impressions) × 100. Engagements usually mean likes, comments,
shares, and saves added together. A post with 500 engagements on an
account with 10,000 followers has an engagement rate by followers of
(500 ÷ 10,000) × 100 = 5%.
Engagements = likes + comments + shares + saves. Switch the tab above to divide by reach or impressions instead of followers.
Leave at 1 for a single post. Set higher to average engagement across several posts with the same follower count.

How to use this engagement rate calculator
Choose a method. By Followers is the most common and easiest
to compare over time. By Reach or By Impressions better reflects
engagement among people who actually saw the post.
Enter total engagements — usually likes, comments, shares,
and saves added together (check the FAQ below for what to include).
Enter the denominator — your follower count, reach, or
impressions for the post(s).
Set number of posts if you're averaging across more than
one, or leave it at 1 for a single post.

The engagement rate formula
Engagement Rate (%) = ( Total Engagements ÷ (Followers or Reach or Impressions × Posts) ) × 100
All three versions use the same basic idea — engagements divided by an
audience size — but the denominator changes what the number actually
tells you:

By Followers

Worked example
Example. A post gets 320 likes, 45 comments,
110 shares, and 25 saves (500 total engagements) on an account with
10,000 followers.
Engagement rate = (500 ÷ 10,000) × 100 = 5%
If the same post only reached 6,000 of those 10,000 followers, the
engagement rate by reach would be higher: (500 ÷ 6,000) × 100 = 8.3% —
which is why the method you choose changes the number significantly.

These are general rules of thumb widely used in social media marketing,
not fixed thresholds — typical engagement rates vary by platform, content
type, industry, and audience size. Smaller accounts often see higher
engagement rates than large ones.
Who uses an engagement rate calculator
Social media managers reporting on content performance, marketers
comparing campaigns or vetting influencer partnerships, small business
owners checking whether their content is resonating, and creators
tracking their own growth all use this calculation regularly.
Tips for a more accurate engagement rate
Be consistent with what counts as an engagement — decide
whether to include saves and shares, and use the same definition
every time you measure.
Use reach, not followers, when comparing posts that weren't
shown to your full audience — algorithmic feeds mean not every
follower sees every post.
Track trends over time rather than judging a single post —
one viral post can skew a snapshot.
Compare like with like — video, image, and text posts often
have naturally different engagement rates on the same platform.
Engagement rate calculator FAQs
What is the formula for engagement rate?
Engagement Rate = (Total Engagements ÷ Followers,
Reach, or Impressions) × 100. The most common version divides by
follower count.
What counts as an "engagement"?
Most commonly likes, comments, shares, and saves
added together. Some marketers also include clicks or video views —
the important thing is using the same definition consistently when
comparing over time.
What's a good engagement rate?
As a general rule of thumb, under 1% is often
considered low, 1-3.5% average, 3.5-6% good, and above 6% excellent
— but this varies significantly by platform, industry, and account
size, so compare against your own history and similar accounts.
Should I calculate engagement rate by followers or by reach?
By followers is simplest and most common for
tracking your own account over time. By reach is more accurate for
judging how compelling a specific post was, since not every follower
sees every post.
Why is my engagement rate different on different platforms?
Each platform has its own algorithm, audience
behavior, and typical engagement norms, so raw engagement rate
numbers aren't directly comparable between platforms like Instagram,
TikTok, Facebook, or LinkedIn.
Does a smaller account usually have a higher engagement rate?
Often, yes. Smaller, more niche audiences tend to be
more engaged per follower than very large accounts, where a smaller
share of followers interacts with any given post.
How do I calculate average engagement rate across multiple posts?
Add up total engagements across all the posts,
then divide by (your denominator × number of posts). The "Number of
posts" field in this calculator does that automatically.
