Calculate your social media engagement rate

Calculate social media engagement rate using likes, comments, shares, saves and followers or reach.

Formula: (Likes + Comments + Shares + Saves) / Followers or Reach x 100

Last updated: September 14, 2026Method: Total interactions / followers or reach x 100

How to use the engagement rate calculator

Enter likes, comments, shares and saves, then choose followers or reach as the denominator. The calculator totals the interactions and divides them by the selected audience measure. The optional target rate shows how many total engagements would be needed to hit that percentage.

Engagement rate formula

Engagement rate = (Likes + Comments + Shares + Saves) / Followers or Reach x 100. Use the same numerator and denominator consistently when comparing results.

Example: 50,000 followers

If a post receives 1,500 total engagements from an account with 50,000 followers, engagement by followers is 3%. If the post reached only 25,000 people, engagement by reach would be 6%. The method changes the context, so always label which denominator you use.

Followers vs reach: which denominator should you use?

Engagement by followers can be useful for account-level comparisons, while engagement by reach can better reflect how the people who actually saw a post interacted with it. Platform metric definitions differ, so avoid treating one universal percentage as a benchmark across every platform and content format.

Frequently asked questions

Should saves and shares be included?

Include them when the platform provides those metrics and they are meaningful for the comparison you are making.

Can I compare Instagram and TikTok rates directly?

Use caution. Platform behavior, reach mechanics and available engagement metrics differ.

Why is engagement by reach often higher?

Reach is usually smaller than total follower count, so dividing the same engagement volume by reach can produce a higher rate.

What is a good engagement rate?

There is no single rate that applies to every platform, audience size, niche and content format. Compare with your own historical performance and like-for-like accounts.
