Empowering millions with free, accurate medical calculators and health tools.
MedicalToolKit exists to make healthcare information accessible to everyone. We believe that understanding your health metrics should be simple, free, and available to anyone with internet access. Our mission is to provide accurate, easy-to-use calculators and health tools that help people make informed decisions about their wellness.
MedicalToolKit is built and maintained by a dedicated editorial team focused on health technology and evidence-based content. Every calculator formula and every article passes through our structured review process before publishing — see our full Editorial Policy for details on how we source and verify medical information.
Our content is researched and reviewed against current clinical guidelines from organizations including the WHO, CDC, ADA, AHA, and ACOG. Every article cites its sources, and every calculator formula is validated against published reference values before going live. We update content when major guidelines change.
We currently offer 15 comprehensive health calculators covering multiple health areas:
Every calculator and article goes through a 5-step process: research from authoritative sources, formula validation against published reference values, careful writing, medical review against current guidelines, and ongoing updates as standards change.
