Engagement Rate Calculator

One post, four answers

Here is one Instagram post run through all four bases. The numbers are illustrative, not from a real account, and they are the calculator's defaults, so you can check every line. The post earned 320 likes, 18 comments, 12 shares and 40 saves: 320 + 18 + 12 + 40 = 390 engagements. The account has 12,000 followers; the post reached 4,800 accounts and was seen 6,500 times.

The post did not change; only the divisor did. The result runs from 3.25% to 8.13%, a 2.5x spread from the same 390 engagements. A rate means nothing until you say what it was divided by. For the term itself, see engagement rate, defined.

Views equal impressions in this example on purpose. Meta's Instagram API reference says that for media created after July 2, 2024 the impressions metric “is deprecated”, and it lists a separate views metric. For a recent Instagram post, views may be the only one of the two you can get. On other platforms the two can differ.

Instagram and TikTok, worked through

Instagram. The calculator opens on Instagram, divided by followers, so the example post reads 390 ÷ 12,000 × 100 = 3.25%. Change “Divide by” and the same post reads 8.13% by reach and 6.00% by impressions. Rival IQ's 2026 all-industry Instagram median, 0.30%, is per post by followers, so of those three results only the 3.25% can be set against it.

TikTok. Pick TikTok and the base switches to views; the saves box becomes Saves (favorites). The same 390 engagements over 6,500 views give 390 ÷ 6,500 × 100 = 6.00%. That views default is a convention, not a TikTok rule: we could not find TikTok documentation that defines engagement rate. Rival IQ's TikTok median, 2.01%, is by followers, so set it against this post's followers result (3.25%), not the 6.00% by views.

Facebook starts on followers and counts link clicks in place of saves. LinkedIn starts on impressions, calls shares reposts, and has no verified followers-based median, so compare a LinkedIn post with your own earlier posts on the same base.

Which base to use

Followers suits comparing accounts, or one account over months, and is the only base for which we could verify a public benchmark (below). It counts every follower whether or not the post reached them, so the rate moves with how widely the post was shown, not only with how people responded to it.

Reach judges the post itself: of the people who saw it, how many reacted. Meta's developer docs define Instagram reach as the “Total number of unique accounts that have seen the media object”. We found no verified public benchmark that uses reach, so compare reach-based rates only with your own posts. See reach, defined and engagement rate vs reach for how the two metrics relate.

Impressions fit paid and boosted posts, because paid delivery is counted in impressions and this base lines up with CPM and CTR. Meta defines Instagram impressions as the “Total number of times the media object has been seen”, so repeat views lower the rate compared with reach. More in impressions, defined and engagement rate vs impressions.

Views fit short-form video. Meta's media insights reference describes Instagram views as the “Total number of times IG Media has been played on Instagram”. This calculator defaults TikTok to views, but we could not find a TikTok page that defines engagement rate that way, so treat it as a convention, not a TikTok rule.

Several posts: pool, don't average

Say post A got 50 engagements from a reach of 500 (10.00%) and post B got 200 from a reach of 10,000 (2.00%). The average of the two percentages is 6.00%. The pooled rate is (50 + 200) ÷ (500 + 10,000) × 100 = 2.38%. The average lets a small post outweigh one that reached twenty times as many people, so the calculator pools: enter totals summed across your posts and the number of posts. For the followers base it multiplies your follower count by the number of posts, giving a per-post rate.

Benchmarks, and why they disagree

The one public benchmark we could check end to end is Rival IQ's 2026 Social Media Industry Benchmark Report, published by Quid on March 5, 2026, covering 2025. It samples “150 companies at random from each industry” across 18 industries, takes each industry's median company, and states: “Engagement rate is calculated by dividing total interactions by follower count.” The sample covers “organic and paid posts”, and the report's charts label each figure “Engagement rate per post (by follower)”, the same thing this calculator's followers base returns.

Read it narrowly. The sample is “national and international companies”, so it says little about a small local account. Each all-industry figure is the middle of the 18 industry medians in the report's charts, so half the industries sit below it; it is a midpoint, not a target. And the base is followers, so the table can only be set against the calculator's followers result. The example post's 3.25% by followers is about 11 times Instagram's median; its 8.13% by reach cannot be compared with that median at all.

Other Instagram benchmarks we came across give different figures. We left them out: the ones we checked gave no method or date, or used a different base. We found no dated, method-stated public benchmark for LinkedIn, or for any platform by reach. If a site quotes one, ask what it divided by.

Engagement rate is not CTR

CTR counts one action, a click to somewhere else, divided by impressions. Engagement rate counts a mixed bucket of reactions that mostly stay on the platform. A post can earn a high engagement rate and almost no clicks. Our comparisons of CTR vs engagement rate and clicks vs engagement rate cover when to use each. For click metrics on ads, use the CTR calculator or the CPC, CPM and CTR calculator.

Mistakes that move the number

• Setting a reach-based rate against a followers-based benchmark. In the example above that alone inflates the number 2.5 times.
• Averaging each post's percentage instead of pooling engagements and audience.
• Counting saves and shares for your account but only likes and comments for a competitor.
• Using followers as the base for paid posts. Ads reach people who don't follow you, so divide by impressions or reach.
• Mixing organic and paid engagement in one rate.
• Reading the rate as a sales result. Engagement is a reaction to a post, not a purchase.

When this number should not drive your decisions

We sell ad management for Google and Meta, so it would suit us to say a high engagement rate means your ads are working. It does not. An engaging ad with a cost per customer above what a customer is worth is still losing money. Judge paid campaigns on conversion rate, cost per acquisition and ROAS; the comparison of conversion rate vs engagement rate explains the gap. And if your goal is organic reach on Instagram or TikTok, you do not need paid-ads software at all; a consistent base and this calculator will tell you more.

What we could not confirm

• How each app's own analytics computes the engagement figure it shows. The Instagram, Facebook, TikTok and LinkedIn help pages we tried did not return readable text, so this calculator does not claim to match any in-app number.
• Exactly what Rival IQ counts on each platform. Its method lists “likes, comments, favorites, reposts, shares, reactions, and video interactions” without defining the last item, so its TikTok median may count actions this calculator does not.
• Any dated, method-stated benchmark for LinkedIn, for TikTok by views, or for any platform by reach.
• Whether TikTok itself defines engagement rate by views. Our views default is a convention, not a rule we found in TikTok's documentation.
