MDCalc Medical Calculator

Your Go-To Clinical Companion

The MDCalc Medical Calculator is a decision-support tool built for healthcare professionals who need quick, reliable numbers at the bedside. With over 550 evidence-based calculators—including risk scores, dosing formulas, and diagnostic criteria—the app replaces bulky textbooks and scattered spreadsheets. It is designed to streamline clinical reasoning without adding clutter to a busy shift.

Comprehensive Clinical Tools at Your Fingertips

From the CHA₂DS₂‑VASc Score for atrial fibrillation stroke risk to the Wells’ Criteria for pulmonary embolism, this platform covers 35+ specialties. Users can toggle between US and SI units, get automatic unit conversions, and receive error warnings to prevent mistakes. The library also includes expert commentary from the original authors and synopses of validation studies, helping clinicians interpret results with confidence.

Earn CME Credits While You Work

A standout feature is the direct integration of continuing medical education. By reading clinical content associated with over 150 calculators, users can earn AMA PRA Category 1™ credits. A personal dashboard tracks earned credits, and a paid plan allows for certificate redemption. This turns everyday clinical lookup time into a streamlined way to fulfill professional education requirements.

Offline Reliable, Online Connected

Most calculators work offline, making the medical calculator app usable in areas with poor connectivity—emergency rooms, remote clinics, or during travel. Internet access is only needed for CME tracking and for linked reference articles. The app also syncs automatically with the web version, so custom lists and favorites stay up to date across devices.

Fast Navigation and Custom Workflow

Searching for a specific tool takes seconds thanks to efficient filters and specialty-based categories. Users can build personalized lists—favorites, recently used, or specialty-specific—for instant access. The interface is clean and uncluttered, letting clinicians focus on the patient, not on fighting the software.
