eGFR & Creatinine Clearance Calculator
Estimate kidney function for staging and drug dosing. Uses the race-free CKD-EPI 2021 equation for eGFR and the Cockcroft-Gault equation for creatinine clearance.
Sex
Weight powers the Cockcroft-Gault clearance. Add height to refine it with ideal/adjusted body weight for dosing.

Enter age and serum creatinine to calculate.
For use by qualified healthcare professionals as a reference aid only. eGFR is indexed to 1.73m² body surface area; Cockcroft-Gault clearance is not. Results are estimates and do not replace clinical judgement. Avoid in acute kidney injury or unstable creatinine.
