About Utilium Hub

Utilium Hub (utiliumhub.com) is a free collection of calculators and tools operated by Utilium, an independent publisher based in India and owned by Mike.

We started the site to give people one clean, fast place for the numbers and text tasks they meet every day — without sign-ups, clutter or paywalls.

• Finance: SIP, EMI, compound interest, inflation, loan comparison and savings goals, with charts.
• Date & time: age, date difference, countdowns, world clock, time zones and holidays.
• Health, daily life & environment: BMI, calories, fuel, electricity and carbon footprint.
• Word & text tools: word counter, case converter, text cleaner, social character counter, slug generator and Markdown previewer.
• Converters & generators: units, currency, international clothing sizes, Roman numerals, QR codes, passwords and more.

Many pages are available in nine languages.

Every calculator uses standard, published formulas (for example the Mifflin-St Jeor equation for calories and the standard reducing-balance formula for EMI). We test results against worked examples before release and add reference sheets and FAQs that explain how each result is calculated.

We review tools regularly, fix reported errors, and add new tools based on visitor requests.

Calculations run in your browser. We don't ask you to create an account and we don't store what you type into the tools. See our Privacy Policy for details.
