Inputs
CrCl declines ~1 mL/min/1.73 m² per year after age 40; CKD stage affects drug dosing
Normal: 0.7–1.3 mg/dL (male); 0.6–1.1 (female); CKD: >1.5 mg/dL sustained elevation
Results
Creatinine Clearance
82.6mL/min
How to Use This Calculator
- Enter patient age, weight (kg), serum creatinine (mg/dL), and sex.
- Review creatinine clearance (CrCl) in mL/min using the Cockcroft-Gault equation.
- Use CrCl to adjust renally cleared drug doses — many guidelines specify cutoffs at 30, 45, or 60 mL/min.
