Simplicalcs — Simple, Free Calculators
Free, fast calculators. No sign-up, no clutter.
Simplicalcs is a growing collection of free browser-based calculators covering finance, health, maths, electrical, travel, and more. VAT, salary, mortgage, BMI, Schengen day tracker, cable sizing, equation solver — everything runs in your browser with no account, no paywall, and nothing blocking the tool. Built for people who just want a fast, reliable answer.
I built Simplicalcs because most free calculator sites are cluttered, untrustworthy, or make you wade through ads before you can use the tool. I wanted something that just works — fast, clean, no account required.
It started with one or two tools and has grown to cover finance (VAT, salary, mortgage), health (BMI, BMR), maths (scientific, equation solver, statistics), electrical engineering, and travel (Schengen day tracker). Everything runs in the browser — no server, no data collected.
Would love feedback on which tools people find most useful, and what's missing.
