Creatinine Clearance Calculator
Estimates creatinine clearance with the Cockcroft-Gault equation from sex, age, weight, and serum creatinine, applying the 0.85 factor for females.
What this calculator does
The Creatinine Clearance Calculator estimates your result instantly from the values you enter, using standard health & fitness formulas. Estimates creatinine clearance with the Cockcroft-Gault equation from sex, age, weight, and serum creatinine, applying the 0.85 factor for females. Calculations run in your browser, so nothing you type is sent to a server, and the output is an estimate rather than a certified or official figure.

About Creatinine Clearance Calculator
The Creatinine Clearance Calculator uses the Cockcroft-Gault equation: ((140 − age) × weight) ÷ (72 × serum creatinine), with the result multiplied by 0.85 for females.
Age is in years, weight in kilograms, and serum creatinine in mg/dL. The estimate is reported in mL/min.
Formula & Mathematical Calculation
Creatinine Clearance (mL/min) = f(Sex, Age (years), Weight (kg), Serum Creatinine (mg/dL))
Calculated according to standard health formulas implemented in the calculator core.
Calculation Example
For a male aged 50, weighing 75 kg, with serum creatinine of 1 mg/dL: ((140 − 50) × 75) ÷ (72 × 1) = 6750 ÷ 72 = 93.75.
The tool reports a Creatinine Clearance of about 93.8 mL/min.
Key Benefits
- Applies the widely used Cockcroft-Gault equation
- Adjusts automatically with the 0.85 factor for females
- Needs only four common inputs
- Reports the estimate in mL/min

Assumptions & Limitations
What the calculation assumes
- Every value you enter is treated as an exact, known amount.
- Any rate or interval you enter is assumed to hold for the whole period unless the form asks for it separately.
- Results use standard published formulas and account only for the values entered above.
- Rounding is applied for display; the underlying calculation uses your full precision.
- Results are returned in the same units you enter, unless the tool states the output unit.
What it does not cover
- Creatinine Clearance Calculator produces a calculated result for reference and learning, not a certified or official measurement.
- Real-world outcomes differ when tolerances, rounding rules or local standards apply.
- Definitions and standards vary by region and change over time; verify the convention that applies to your case.
- Figures are only as accurate as the inputs you supply — check them before acting on the result.
- For work where the result carries real consequences, confirm it against an authoritative source.
