eGFR Calculator
Estimate your kidney function (estimated glomerular filtration rate) from a creatinine result, using the 2021 CKD-EPI equation — the current U.S. standard, which no longer uses race.
Sex
The 2021 equation uses sex but not race.
Enter your creatinine, age (18+), and sex to estimate eGFR.
This calculator is general education and uses standard published equations. It can’t interpret your specific situation — what a result means depends on your history and the rest of your labs, which is a conversation for you and your clinician.
