About CalcPool
We build free, science-backed tools that help real people make better decisions about their health, money, and daily life.
Our Mission
CalcPool was built on a simple belief: the most useful tools in the world should be free. Not freemium. Not "free with a 7-day trial." Actually free — forever, no signup, no tricks.
Every tool we build starts with a real human problem. We ask: what do people actually need to calculate or understand in their daily lives? Then we build the most accurate, most user-friendly version of that tool — and we publish it for free.
We are funded entirely by non-intrusive advertising. We never sell your data, never collect your personal inputs, and never put our tools behind paywalls.

Our Standards
Science-backed methodology
Every tool is built on peer-reviewed research. We cite our sources within each tool and blog article. If a calculation cannot be backed by credible science, we do not build it.
Accuracy over simplicity
We never sacrifice accuracy for ease of use. Our tools account for the variables that matter — your personal context, not just population averages.
Transparent about limitations
Every health and finance tool includes clear disclaimers. Our tools provide information, not medical or financial advice. We are honest about what a calculator can and cannot tell you.
Accessibility for everyone
Our tools are designed to work on any device, in any browser, at any connection speed. We do not use heavy frameworks that would exclude people with older devices or slower internet.
Regular updates
We review and update our tools regularly as new research emerges. Publication and update dates are shown on every tool page.
Have a question or suggestion?
We read every message. If you have an idea for a tool we should build, we genuinely want to hear it.
