How to Calculate Your Instagram Engagement Rate (Simple Formula)

Updated June 2026

Follower count is the number everyone watches, but engagement rate is the one that actually matters — to brands, to the algorithm, and to anyone judging whether your audience is real. The good news: the math is simple.

The basic formula

The most common version, engagement rate by followers:

Engagement rate = (Likes + Comments) ÷ Followers × 100

Say a post gets 300 likes and 20 comments, and you have 5,000 followers: (300 + 20) ÷ 5,000 × 100 = 6.4%. To judge your account overall, average it across your last 10–15 posts rather than cherry-picking one.

A more complete version

For reels and posts that drive saves and shares, those count too. Many marketers use: (Likes + Comments + Saves + Shares) ÷ Reach × 100. Using reach instead of followers is more accurate, since it measures who actually saw the post.

What counts as a good rate?

• Under 1% — low; worth investigating.
• 1–3.5% — average for most accounts.
• 3.5–6% — strong.
• Above 6% — excellent, especially as you grow.

Smaller accounts naturally post higher rates. As followers climb, rates usually settle down — that’s normal.

Dead followers are dragging you down

Notice that followers sit in the denominator. Every inactive or bot account makes your rate look worse without adding a single like.
