About Us

Our mission

We built this site to make the Cockcroft-Gault creatinine clearance calculation clear, transparent, and free to use. Every result shows the inputs, the formula path, and practical context so users can better understand what the number means — and what it does not replace.

What we offer

• A free creatinine clearance calculator (Cockcroft-Gault) that runs in your browser
• Support for common units (mg/dL and µmol/L) and weight-basis options
• Educational explainers on CrCl vs GFR, normal ranges, dosing context, and worked examples
• Clear labeling that this tool is educational and not a substitute for clinical judgment

Clinical review

Clinical content on this website is reviewed by Dr. Emily Carter, PharmD, BCPS, a board-certified clinical pharmacist specializing in nephrology and internal medicine. Her focus includes renal pharmacotherapy, evidence-based dosing, and medication safety for patients with kidney disease.

We aim to keep formulas, explanations, and references aligned with widely used clinical practice and published equations. Content may be updated as guidance and evidence evolve.

Independence and advertising

This website is independently operated. To support free access to the calculator and educational content, we may display advertisements through Google AdSense or similar partners. Ads do not influence our clinical explanations or calculator logic.

Advertising partners may use cookies or similar technologies as described in our Privacy Policy and Cookie Policy. You can manage personalized ads via Google Ads Settings.

Privacy-first calculator design

Calculator inputs (such as age, weight, and serum creatinine) are processed locally in your browser for the purpose of generating a result. We do not intentionally send those clinical values to our servers for storage or marketing.
