About SpeedCalcs
SpeedCalcs is a free calculator hub with 300+ online tools covering finance, health, auto, home improvement, food, travel, pets and more. Every tool is free to use, no sign up required and built to give you an accurate answer fast.
Our Mission
SpeedCalcs exists to give everyone access to accurate, easy to use calculators for completely free. The internet is full of calculator sites that bury results behind paywalls, ads or vague answers. We wanted something different: a clean, fast, honest hub where you get your answer and get on with your day.
Every calculator on SpeedCalcs is hand built, tested for accuracy and written in plain language. When you use one of our tools, you get the number and the context to act on it.
Our Story
SpeedCalcs was founded in Kingston, Jamaica by Alberto Miller a self taught developer who set out to build the most useful free calculator library on the web. Starting from scratch, he built every tool individually using custom scripts, growing the site to 300+ calculators across 30+ categories.
Today SpeedCalcs is used by everyday people, students, bloggers and small business owners across the English speaking world. Beyond the free hub, we also build and deliver custom calculators for businesses and websites that need something specific.
