Our Mission
MedicalCalculatorHub was built to solve a problem every clinician knows: the best clinical scoring tools are scattered across paywalled journals, outdated PDFs, and interfaces that show a number but tell you nothing about what to do with it.
Our mission is to make every validated clinical calculator freely accessible at the point of care — with the scoring logic verified against its primary validation study, interpretation grounded in current guidelines, and a clinical documentation note ready to paste into any EMR.
We focus on depth before breadth. Every tool we publish is better than what exists elsewhere — or we do not publish it.
Why MedicalCalculatorHub Is Different
Primary Source Verified
Every calculator is verified against the original PubMed-indexed validation study — not a secondary description. Scoring logic, thresholds, and MDC/MCID values are confirmed against the original authors' published data.
EMR Documentation Output
Every calculator generates a complete clinical note ready to paste directly into your EHR/EMR — including the tool name, all parameter values, total score, interpretation, and primary reference. No other free calculator site does this.
MCID & Clinical Significance
Results include the Minimal Clinically Important Difference (MCID) and Minimal Detectable Change (MDC) for each tool — so you know whether a change in score is genuinely meaningful or within measurement error.
Privacy by Design
All calculations happen locally in your browser. No patient data is transmitted to our servers, stored, or processed externally. We do not collect personal health information. Read our Privacy Policy →
Clinical Sections — Depth First
Rather than offering shallow coverage across all specialties, we go deep in each section we launch. Every section has a dedicated clinical reviewer before it goes live.

Our Editorial Review Process
Every calculator published on MedicalCalculatorHub follows a documented 5-stage editorial process. This process is mandatory — no tool is published without completing all five stages.
- Primary Source Identification: The original peer-reviewed validation study is located via PubMed and verified as the authoritative source for the scoring algorithm, thresholds, and clinical interpretation. Secondary sources are not used for scoring logic.
- Algorithm Verification: The calculator's scoring logic is coded directly from the primary study. The output is tested against the published example cases or scoring tables in the original paper to confirm exact match.
- Clinical Guideline Alignment: Interpretation thresholds, clinical response recommendations, and MCID values are checked against current specialty guidelines (APTA, RCP, SCCM, ACC/AHA, WHO, NICE) — whichever apply to the tool.
- Clinical Reviewer Sign-Off: A credentialled team member with relevant clinical specialty experience reviews the completed calculator, scoring logic, interpretation text, and EMR documentation note. Any discrepancy triggers a revision cycle.
-
Scheduled Re-Review: Every published calculator carries a
lastRevieweddate. Tools in active guideline areas (sepsis, ICU, cardiology) are re-reviewed every 12 months. Stable instruments are re-reviewed every 24 months or upon any guideline update affecting the tool.
