Calculated Creatinine Clearance Formula and Calculator

Patient's age:  Patient's height:  cm    OR    inches Patient's Actual Body Weight:  kg    OR    pounds Patient's serum creatinine:   mg/dl Patient's sex:   Male  Female

Calculated Creatinine Clearance:

---

Formula
Males:	$$\frac{(140 - \text{patient's age}) \times \text{patient's weight in kilograms}}{72 \times \text{patient's serum creatinine}}$$
Females:	$$\frac{(140 - \text{patient's age}) \times \text{patient's weight in kilograms}}{72 \times \text{patient's serum creatinine}} \times .85$$

Note: If the patient’s height is < 60 inches, the patient’s body mass index (BMI) and fat-free mass (FFM) are taken into consideration for the calculation of ideal body weight, used to cap the weight used in this formula at IBW x 1.4.
