CKD Progression Calculator

Estimate your eGFR, identify your CKD stage, and understand what to expect — using the same validated equations used by kidney specialists.

18 years or older
Used in CKD-EPI 2021 equation
From your most recent blood test (serum creatinine)
Add UACR for progression risk estimate (optional — more precise results)
From urine test. Enables CKD progression risk estimate (Tangri 2011)
If UACR is unknown, eGFR and stage will still be calculated accurately. UACR enables the 2-year and 5-year ESRD risk estimate.
