How to Calculate Engagement Rate (2026 Formulas + Free Calculator)
Step-by-step guide to calculating engagement rate on Instagram, TikTok, LinkedIn, and more. Three formulas explained, industry benchmarks, and a free calculator you can use right now.
Engagement rate is the single most useful number in social media — and the most misunderstood. This guide walks through the three formulas that actually matter in 2026, what counts as "good," and a calculator you can use without leaving the page.
The three formulas you need to know
There isn't one engagement rate — there are three, and each answers a different question.
ERF = (likes + comments + shares + saves) ÷ followers × 100
The industry-standard benchmark. Use this when comparing your account against published industry averages.
ERR = total interactions ÷ post reach × 100
The most accurate per-post measure. Use this to evaluate whether a single post resonated with the people who actually saw it.
ERV = (likes + comments + shares) ÷ views × 100
Standard for video-first platforms (TikTok, Reels, YouTube Shorts) where most viewers aren't followers.

What counts as "good" in 2026
| Rate | Verdict | What it means |
|---|---|---|
| < 1% | Below average | Content isn't landing, or follower list has gone cold. |
| 1 – 3.5% | Average | Typical for most established accounts. |
| 3.5 – 6% | Good | Resonant content with an active audience. |
| > 6% | Excellent | Niche-leader territory. |
Small accounts (under 10K followers) almost always post higher rates than large accounts. A 4% rate at 500K is exceptional; the same 4% at 2,000 is average.
Platform-by-platform cheat sheet
Step-by-step: calculate it by hand
- Pick a window. One post (single-post rate) or the last 30 days (account rate).
- Add the interactions. Likes + comments + shares + saves. For video-first platforms, add reactions instead of likes.
- Pick the denominator. Followers (benchmarking), reach (per-post quality), or views (video).
- Divide and multiply by 100. That's your rate.
- Compare against the same denominator. Don't compare ERR to ERF — they're different metrics.
Three things that fix a low engagement rate
Remove inactive followers every quarter. A 'smaller' account with active followers will out-engage a bloated one every time.
Reach and engagement compound from the first 3 seconds (video) or first line (text). Re-write your opener before you write more posts.
A great post at 3 AM still loses to a mediocre one at peak. Check the day-of-week guides in our Best Times to Post hub.
