How to calculate Instagram engagement rate

TL;DR
ER = (Likes + Comments + Saves + Shares) ÷ Reach × 100%. Saves count in 2026 — they didn't used to, and ignoring them underestimates your ER by 15–25%.

If you don't have access to reach data (public accounts can't see reach on others), fall back to followers and expect the number to read slightly lower than the true value. Agencies consider the reach-based formula the only legitimate one in 2026.

# Instagram 2026 ER formula (reach-based)
IG_ER = (likes + comments + saves + shares) / reach * 100

# Example: a post reaching 45,000 accounts
→ (720 + 48 + 62 + 35) / 45000 * 100 = 1.92%

Average Instagram engagement rate in 2026

TL;DR
Platform average is 0.98%, down from 1.19% in 2025. Small accounts (1K–10K) average 2.4%, mega accounts below 0.5%.

2026 is the fourth consecutive year of declining Instagram ER. The main drivers are Reels taking share from feed posts (Reels ER is lower but reach is higher), and Meta's algorithm prioritizing paid distribution over organic reach.

How to improve your Instagram engagement rate

TL;DR
Carousels > Reels > static posts. If you're not using carousels in 2026 you're leaving 40% of your ER on the table.

Carousels force multiple taps, and Instagram counts each swipe as engagement. A single carousel swipe-through equals 2–10× the interaction of a static post. Shift at least half your posting cadence to carousels in your niche and watch ER climb within two weeks.

Frequently asked questions

What is a good Instagram engagement rate in 2026?+
Platform average is 0.98%. Anything above 1.5% is good, 3%+ is very good. Niche matters: finance/parenting hit 1.8%+ averages while lifestyle/entertainment drop to 0.7%.
Should I use reach or followers?+
Always reach when available. Reach gives a stable number regardless of how much the algorithm pushes each post. Follower-based ER penalizes growing accounts that pick up inactive followers.
Do saves count in 2026?+
Yes — saves are the highest-weighted signal in Meta's internal algorithm. Including them in ER calculation is standard practice in 2026.
Why is my Instagram ER lower than my TikTok ER?+
Different platforms, different math. Instagram uses reach (or followers); TikTok uses views. They measure different things. A 2% IG ER and a 6% TikTok ER can represent identical audience loyalty.
