Adult Creatinine Clearance Calculator


Creatinine clearance calculator determines the kidney function of your body. The normal creatinine clearance values are:

• Male: 97 to 137 ml/min

• Female: 88 to 128 ml/min

A lower than normal creatinine clearance may indicate kidney or renal function failure.

Adult Creatinine Clearance Calculator
Select sex:
Enter age: years
Enter weight: Weight unit:
Enter height: Height unit:
Enter serum creatinine: mg/dL


* Based on the Cockcroft-Gault equation:

For males:

Clcr = [140 - age] x BW / [72 x Scr]

where age = in years

BW = actual body weight, in kg

Scr = serum creatinine, in mg/dL

For females:

Clcr (mL/min) = 0.85 x Clcr of males

For obese patients (ABW >= 120% of IBW): use adjusted ideal body weight to calculate Clcr:

Adjusted IBW (kg) = IBW + [0.4 x (ABW - IBW)]

where IBW = ideal body weight (see IBW Calculator), in kg

ABW = actual body weight, in kg
