NakupSladilcev.si Engagement Calculator

A completely free Slovenian-language engagement-rate calculator for Instagram and TikTok. Creators enter likes and comments manually and choose followers, reach or views as the denominator. The browser calculates (likes + comments) / selected denominator × 100 and explains why different denominators are not directly comparable. No registration, payment, profile lookup or paid API is needed. Inputs stay in the browser. A worked example uses 40 likes, 10 comments and 1,000 followers to show 5%; this is a mathematical example, not a customer result. The tool does not grade accounts or predict reach, growth or sales. It is operated by a Czech online business, NakupSladilcev.si, which separately offers paid follower, like and view services. Using the free calculator does not require purchasing them.
