How to Calculate Monthly Engagement Rate on Facebook

Calculating your monthly engagement rate is essential for understanding how effectively your content resonates with your audience over a specific period. Unlike a per-post metric, the monthly rate gives you a holistic view of your page's performance.

The Formula

The standard formula used by most social media marketers to determine the monthly engagement rate based on followers is:

Engagement Rate = ((Likes + Comments + Shares) / Total Followers) × 100

This formula aggregates all public interactions (reactions, comments, and shares) accumulated throughout the month and divides them by your total follower count. The result is multiplied by 100 to get a percentage.

Metric Definitions

• Total Likes/Reactions: The sum of all thumbs-up, hearts, and other reaction emojis across all posts published in the month.
• Total Comments: The aggregate count of comments received on your posts for the month.
• Total Shares: The number of times your posts were shared by users to their own feeds or friends.
• Total Followers: The number of people following your page at the end of the calculation period.

Why This Metric Matters

While "Reach" is often used for individual posts, using "Followers" for a monthly aggregate provides a stable benchmark for growth. It answers the question: "Of the people who have subscribed to see my content, how many are actually interacting with it this month?"

What is a Good Facebook Engagement Rate?

Benchmarks vary significantly by industry, but generally speaking:

• Below 0.5%: Low engagement. You may need to revisit your content strategy.
• 0.5% – 1.0%: Average. This is a standard rate for business pages.
• Above 1.0%: Good. Your audience is actively interested in your content.
• Above 3.0%: Excellent. This is viral territory or highly niche community engagement.

Example Calculation

Let's say your Facebook page has 10,000 followers. In the month of September, you posted 10 times. Across those 10 posts, you received:

• 300 Likes
• 50 Comments
• 25 Shares

First, calculate total interactions: 300 + 50 + 25 = 375 interactions.

Next, divide by followers: 375 / 10,000 = 0.0375.

Finally, multiply by 100: 0.0375 × 100 = 3.75%.

This result would indicate an excellent level of engagement for the month.
