Instagram Engagement Rate Calculator
See if your IG account is over- or under-performing the median for its size.
Your numbers
Use the average of your last 9 posts for best accuracy.
Formula: ER% = (likes + comments) ÷ followers × 100
Your result
Your account is in the "Micro (1k–10k)" bracket (1,000–9,999 followers).

Engagement rate — the single most important metric
Instagram's algorithm went through two significant rewrites in 2024-2025. The era when raw follower count drove everything is over — what now decides reach is how strongly each follower reacts to what you post. Engagement rate is the single number that measures exactly that.
Why follower count alone isn't enough
A high follower count with a low ER% gets throttled by the algorithm ("low quality, hide it"). Meanwhile a smaller account with 2× the median ER for its bracket lands in the Explore tab and grows organically. Per the 2025 RivalIQ report, the top decile of ER% by bracket sees on average 3.2× the reach of accounts at the median.
Four proven ways to lift organic ER
- 50%+ Reels share: 1.4× average ER vs. static posts.
- Post 3-5×/week, not daily: daily posting actually depresses ER.
- 100% reply rate in first 24h: reply velocity is an explicit algorithm signal.
- Question stickers in Stories: two-way interactions receive a reach boost.

Frequently asked questions
What is engagement rate, exactly?⌄
Engagement rate (ER%) is the sum of likes + comments on a post divided by your follower count, expressed as a percentage. It measures how strongly your content resonates with the people who already follow you.
What counts as a "good" ER%?⌄
It depends on account size. Nano accounts (under 1k) average ~7%, while mega accounts (1M+) average ~0.8%. This calculator automatically benchmarks you against accounts your size, drawing on the 2025 RivalIQ and HypeAuditor reports.
Are saves included?⌄
No. Saves typically aren't reported in the standard ER formula because they're harder to surface and can't be reliably back-fed from non-business accounts. If you want to track them, use (likes + comments + saves) ÷ reach × 100 — but only when Instagram gives you reach data.
What should I do if my ER is low?⌄
First check posting frequency (3-5 posts/week is the sweet spot). Then increase your share of carousels and Reels — both average 1.4× higher ER than static posts under the 2025 algorithm. Finally, lead captions with a question to nudge comments.
Where does the data come from?⌄
Synthesised from RivalIQ's "2025 Social Media Industry Benchmark Report" and HypeAuditor's quarterly ER tables. We refresh annually in January.
