Engagement rate formulas explained
The most common engagement rate formula is ER by followers: (Total Engagements ÷ Followers) × 100. This is widely used for influencer marketing benchmarks. ER by reach: (Total Engagements ÷ Reach) × 100 measures how engaging your content is for people who actually saw it — more accurate for organic performance measurement. ER by impressions: (Total Engagements ÷ Impressions) × 100 accounts for repeat views. For influencer comparison, always use the same formula — mixing ER by followers with ER by reach produces misleading comparisons.
| Platform | Good ER (micro) | Good ER (macro) | Formula used |
|---|---|---|---|
| 3–6% | 1–3% | Engagements ÷ Followers | |
| TikTok | 4–18% | 2–8% | Engagements ÷ Views |
| 2–5% | 1–2% | Engagements ÷ Impressions | |
| Twitter/X | 0.5–2% | 0.1–0.5% | Engagements ÷ Impressions |
| YouTube | 2–5% | 1–2% | Engagements ÷ Views |
Why engagement rate matters for monetization
Brands pay premium rates for high-engagement accounts because engagement signals an active, trusting audience. A micro-influencer (10K–50K followers) with 6% engagement is more valuable to most brands than a macro-influencer (500K+ followers) with 0.8% engagement — the micro-influencer's audience is more likely to act on recommendations. For AdSense and affiliate revenue, engagement correlates with dwell time and click-through rates. Platforms also use engagement rate as a ranking signal — higher engagement posts get wider organic reach in feeds and recommendations.
Worked examples
Instagram post ER
Inputs: 450 likes + 32 comments · 15,000 followers
Result: (450 + 32) ÷ 15,000 × 100 = 3.21%
Reach-based ER
Inputs: 482 engagements · 20,000 reach
Result: 482 ÷ 20,000 × 100 = 2.41%
