The engagement rate formula
Engagement rate = (likes + comments + saves + shares) ÷ followers × 100. It converts raw interactions into a percentage you can compare across accounts of different sizes. Swap followers for reach to measure how a specific post performed with the people who actually saw it.
What counts as engagement?
Likes and comments are the baseline. Saves and shares are weighted heavily by both the Instagram and TikTok algorithms because they signal genuine value, so include them when you have the data. Views alone are not engagement — they measure reach, not interaction.
Engagement rate benchmarks
- Below 1% — below average; revisit content or audience quality.
- 1-3.5% — average for most Instagram accounts.
- 3.5-6% — strong, especially for larger accounts.
- 6%+ — excellent; common on small, tight-knit or viral accounts.

Frequently asked questions
What is a good engagement rate?
It varies by platform and follower count. On Instagram, 1-3.5% is roughly average, 3.5-6% is strong, and above 6% is excellent — smaller accounts usually score higher. TikTok engagement runs higher than Instagram. Always compare against accounts of a similar size in your niche rather than a single universal benchmark.
How do you calculate engagement rate?
The most common method is total engagements (likes + comments + saves + shares) ÷ followers × 100. For a single post you can use the engagements on that post; for an account, average across recent posts. Using reach instead of followers gives engagement rate by reach, which is often more accurate for content performance.
Should I use followers or reach?
Both are valid. Engagement rate by followers measures how active your audience is and is what most brands quote. Engagement rate by reach measures how compelling a specific post was to the people who saw it, and is better for judging whether a piece of content actually broke out. This calculator works with either — just enter reach in the followers field.
Why does engagement rate matter?
It signals how much an audience actually cares, not just how big it is. Brands use it to vet creators for partnerships, and creators use it to prove value. It's also an early signal of a breakout: a post engaging far above an account's baseline is often going viral before view counts catch up.
