How is engagement rate calculated?
The most common formula is (likes + comments + shares + saves) ÷ reach × 100, expressed as a percentage. Some calculators use followers as the denominator instead of reach for accounts without analytics access. Always note which denominator you used; engagement-by-reach and engagement-by-followers can differ significantly, especially on accounts where reach exceeds follower count.
What is a good engagement rate?
Industry benchmarks vary by platform: Instagram 1 to 3%, TikTok 5 to 9% (higher because views vastly outpace followers), LinkedIn 2%, Facebook 0.5 to 1%, X 0.5%. Micro-influencers (under 10K followers) consistently outperform macro-influencers because their audiences are tighter and more responsive. Set targets relative to your size tier, not absolute platform averages.
Should I include saves and shares?
Yes, especially for Instagram and TikTok where saves and shares correlate strongly with algorithmic reach. A post with high saves but few likes signals deep value to the audience and is rewarded. Excluding them undercounts true engagement. Use a calculator that breaks out each engagement type so you can analyze drivers separately.
How do I compare engagement rates across platforms?
Compare within platforms first, not across. TikTok's 7% rate and Facebook's 0.7% rate are not directly comparable because the platforms surface content differently. Track each platform's rate over time against your own baseline and against creators in your niche on the same platform. That delta tells you whether a campaign worked.
Do paid posts and organic posts use the same formula?
The math is the same, but interpret results separately. Paid reach is purchased and inflates the denominator, so paid posts often look like they have lower engagement rates than organic. Calculate organic-only engagement to track audience health and paid-only engagement to evaluate ad creative; mixing them muddies both.
How often should I calculate engagement rate?
Monthly is the sweet spot for trend tracking. Daily is too noisy for most accounts; weekly works for high-volume creators. Track average engagement rate per post type (Reel vs photo vs carousel) so you can shift content mix toward formats that perform best for your audience.
