Engagement Rate Calculator: How to Calculate Instagram Engagement Rate (and What's Good)
By BookTheCrowd · · Guides
What is a good engagement rate on Instagram, TikTok or YouTube? Here's the simple engagement rate formula, worked examples you can copy, rough benchmarks by follower size, and how brands and creators should actually use the number.
Engagement rate is the number brands look at before almost anything else. And it's the number creators love to put in their media kits.
But people calculate it in different ways, which is why one tool says 2% and another says 6% for the same account.
This guide gives you a simple engagement rate calculator you can do on your phone, worked examples, and a rough idea of what a good engagement rate looks like in 2026.
What Is Engagement Rate?
Engagement rate shows how many people interact with content compared to how many could have.
Interactions usually include:
- Likes
- Comments
- Shares
- Saves
The "how many could have" part is either followers or reach/views. That choice is why numbers differ between tools.
Formula 1: Engagement Rate by Followers (Most Common)
Engagement rate = (likes + comments) ÷ followers × 100
This is what most brands use, because anyone can see likes, comments and followers on a public profile.
Worked example:
- Followers: 25,000
- Average likes on the last 10 posts: 900
- Average comments: 60
- (900 + 60) ÷ 25,000 × 100 = 3.84%
How to do it properly:
- Take the last 10–12 posts
- Skip pinned posts, giveaways and anything boosted with ads
- Add up likes and comments, divide by the number of posts
- Divide by followers and multiply by 100
Formula 2: Engagement Rate by Reach (Most Accurate)
Engagement rate = (likes + comments + shares + saves) ÷ reach × 100
Reach is only visible to the creator, so brands need to ask for screenshots from Instagram insights. It's more accurate because it measures the people who actually saw the post.
Worked example:
- Reach: 18,000
- Likes 900 + comments 60 + shares 120 + saves 220 = 1,300
- 1,300 ÷ 18,000 × 100 = 7.2%
Notice how much higher this is than the follower-based number for the same post. Always compare like with like.
Formula 3: Engagement Rate by Views (Reels, TikTok, YouTube)
For video, views matter more than followers:
Engagement rate = (likes + comments + shares) ÷ views × 100
Worked example (TikTok):
- Views: 40,000
- Likes 2,800 + comments 140 + shares 260 = 3,200
- 3,200 ÷ 40,000 × 100 = 8%
On YouTube, many brands also look at views per video ÷ subscribers, which shows how much of a channel's audience still watches.
What Is a Good Engagement Rate?
There's no official standard, and it changes by platform, niche and account size. As a rough guide for follower-based engagement on Instagram:
- Under 1%: low, worth checking more closely
- 1–3%: normal for many accounts
- 3–6%: good
- Over 6%: excellent, common for small creators with loyal audiences
Engagement usually drops as accounts grow. A 2% rate on 500K followers can be more impressive than 4% on 5K.
TikTok engagement by views is often higher than Instagram engagement by followers, because views already filter to people who watched.
Engagement Rate Mistakes to Avoid
- Comparing different formulas: a reach-based rate will always look higher
- Using one viral post: take an average of 10–12 posts
- Counting giveaways: "comment to win" posts inflate numbers
- Ignoring comment quality: 500 emoji comments aren't the same as 50 real questions
- Forgetting fake followers: low engagement on a big account can mean a bought audience (see our fake followers check)
How Brands Should Use Engagement Rate
Engagement rate is a filter, not a final answer. Use it to:
- Remove obviously weak or fake accounts
- Compare creators of similar size in the same niche
- Spot creators whose audiences really listen to them
Then look at audience location, content fit and past results. After the campaign, measure what matters: clicks, codes, bookings and sales. Our guide to measuring influencer marketing ROI shows how.
How Creators Can Improve Engagement Rate
- Start videos with a strong hook in the first 2 seconds
- Ask a specific question in your caption
- Reply to comments in the first hour
- Post content people want to save (tips, lists, recipes)
- Use stories to talk with your audience daily
- Post consistently in one niche
A strong engagement rate also helps you charge more. Put it in your media kit, with the formula you used. See how to get brand deals.
