Creatinine Clearance Calculator

Calculate estimated GFR (eGFR) and creatinine clearance using Cockcroft-Gault, MDRD, and CKD-EPI 2021 equations.

AGE (years)

WEIGHT (kg)

SERUM CREATININE (mg/dL)

SEX

RACE (MDRD/CKD-EPI)

Cockcroft-Gault CrCl

Estimates creatinine clearance. Uses weight.

—mL/min

CKD-EPI 2021 eGFR

Preferred equation. More accurate at higher GFR.

—mL/min/1.73m²

MDRD eGFR

Older equation. Underestimates at normal GFR.

—mL/min/1.73m²

CG: CrCl = [(140 − age) × weight] / (72 × SCr) × 0.85 if female

CKD-EPI 2021: 142 × min(SCr/κ, 1)^α × max(SCr/κ, 1)^-1.200 × 0.9938^age × sex factor

MDRD: 175 × SCr^-1.154 × age^-0.203 × race × sex
