Cockcroft-Gault Calculator

Estimate creatinine clearance from age, weight, sex, and serum creatinine.

 

 

 

CrCl (ml/min)

About this calculator

Use this calculator for CrCl = (140 − age) × kg / (72 × Scr) × 0.85 if female, with creatinine in mg/dl. Use adjusted body weight if your protocol says so. Drug labels still quote this more than CKD-EPI. This is not an eGFR in ml/min/1.73 m².

Weight can be entered in kilograms (kg) or pounds (lb).

Sex: Female multiplies by 0.85.

Age: Age in years.

Weight: Weight the protocol wants (often actual or AjBW), in kg or lb.

Creatinine: Serum creatinine, mg/dl.

CrCl: Creatinine clearance, ml/min.
