Understanding This Calculator
Cockcroft-Gault Formula
This calculator estimates creatinine clearance (CrCl) using the Cockcroft-Gault equation.
CrCl = ((140 - Age) × Weight) / (72 × SCr)
Note for Females: Multiply the result by 0.85.
- Age: Years
- Weight: Kilograms
- SCr: Serum Creatinine (mg/dL)
Example 1
Male, 60 years, 70 kg, SCr 1.0.
- Num: (140 - 60) × 70 = 5600
- Denom: 72 × 1.0 = 72
- Result: 5600 / 72 = 77.8 mL/min
Example 2
Female, 60 years, 70 kg, SCr 1.0.
- Result for male: 77.8 mL/min
- Female adjustment: 77.8 × 0.85 = 66.1 mL/min
How to Use
- Enter Serum Creatinine level.
- Enter Age and Weight.
