# Engagement rate calculator: check any creator by username > Enter an Instagram or YouTube username to see its engagement rate and how it compares. - Page title: Engagement rate calculator by username | Spytrend - Page description: Free engagement rate calculator: enter an Instagram or YouTube username and see its engagement rate against accounts of the same size. First lookup free. - Tool: https://spytrend.com/engagement-rate-calculator - Embeddable version: https://spytrend.com/engagement-rate-calculator/embed - All free tools: https://spytrend.com/tools - The product behind it: https://spytrend.com/?utm_source=tools&utm_medium=free_tool&utm_campaign=engagement-rate-calculator To work out a creator’s engagement rate, pick the platform, enter the username and press Calculate. You get the engagement rate as a percentage, a label saying whether it is high, average or low for an account of its size, the follower or subscriber count, and the median likes, comments and views per post. This page reads one account from the creators we have collected. You do not type in likes or followers; we already have them. ## The engagement rate as a percentage, compared with accounts of the same size You get one number and one comparison. A rate on its own says little: large accounts engage less than small ones, so the page also tells you where the rate sits among accounts with a similar follower count. What comes out: - **The engagement rate.** On Instagram, the median likes plus comments per post divided by followers. On YouTube, the median likes per view across recent videos. - **How it compares.** A label: high, average or low for accounts of the same platform and a similar size. - **Followers or subscribers.** The size of the audience, which decides the accounts the rate is compared with. - **Median likes and comments.** The middle count per recent post or video. YouTube gets no comments line: our video data has no comment counts. - **Median views.** The middle view count across recent YouTube videos or Instagram reels. Instagram photos have no view count, so an account that posts mostly photos gets no views line. We use the median, not the average, so one viral post does not inflate the rate, the likes or the views. ## Engagement rate calculator: three steps 1. **Pick the platform** Choose Instagram or YouTube above the field.

Want the full picture of an account? The Instagram and YouTube account checks turn the same numbers into a quality score out of 100. ## One formula per platform, the median of recent posts Instagram: for each recent post, likes plus comments divided by followers; the rate is the median of those numbers. YouTube: for each recent video, likes divided by views; the rate is the median. We do not have comment counts for YouTube videos, so they are left out rather than guessed. The comparison puts the rate next to accounts of the same platform with a similar follower count: the bottom quarter reads low for its size, the top quarter high, the middle half average. ## Free version limits Your first lookup is free, no sign-up. Leave your email for one more, then create a free Spytrend account: it opens the full ad library, and paid plans add fresh ads and every filter. One lookup reads one account from our database, and the result stays on this page. An account we have not collected yet gets no rate. ## Price a creator on attention — not on a follower count Two creators with the same follower count can reach very different numbers of people. The engagement rate shows how much of the audience actually reacts, which is what a sponsored post buys. A brand manager checks the rate before agreeing a fee, and asks for a lower one when it sits below accounts of the same size. ## The ads brands actually run, beside the creators they pay This tool checks one account at a time. Spytrend is an ad intelligence platform for Facebook and TikTok advertising: a full five-year archive of ads, AI-classified into 33 business categories, with every advertiser assembled into a single card — all ads, pages, domains and countries in one place. ### Two jobs where one rate is not enough - **Choosing what the creator should make.** The ads that brands in the niche keep running show which hooks and formats work there, so the brief starts from evidence instead of taste. - **Seeing who else pays for the same audience.** An advertiser’s card lists every ad, page and country, so you can see how hard competitors push the audience you are about to buy. ### How to start [Create a free account](https://spytrend.com/register?source=tools&returnTo=%2Fads%3Ffrom%3Dtools&utm_source=tools&utm_medium=free_tool&utm_campaign=engagement-rate-calculator) and search a brand in the creator’s niche. The free account opens the ad library; paid plans add fresh ads and every filter. ## FAQ - **How do I calculate an engagement rate?** On Instagram, divide likes plus comments on a post by followers and take the median across recent posts. This page does it for you: pick the platform, enter the username and press Calculate. - **Is the engagement rate calculator free?** Yes, to start. Your first lookup is free, no sign-up, and your email unlocks one more. After that, a free Spytrend account opens the full ad library; paid plans add fresh ads and every filter. - **What is a good engagement rate?** It depends on the platform and the account’s size: small accounts usually engage more than large ones. That is why the page compares the rate with accounts of a similar size instead of one fixed number. - **Why is the YouTube rate likes per view?** Because views, not subscribers, show who watched a video, and our video data has views and likes but no comment counts. - **Why median views, not average views?** One viral video can pull the average far above what most videos get. The median is the middle value across recent posts, so the likes, comments and views show what a usual post gets. On Instagram, views count reels only: photos have no view count. - **Do I need to enter likes and followers myself?** No. Enter the username; the numbers come from the posts we have collected for that account. ## Start from one creator. See the ads behind the niche. One rate tells you how an audience reacts. Spytrend shows you the ads that the brands in its niche keep paying for.
