Your Estimated GFR.
The GFR Calculator estimates your Glomerular Filtration Rate using the latest CKD-EPI (2021) formula, the current clinical standard for assessing kidney function. By analyzing serum creatinine levels alongside age and gender, we provide a vital indicator of renal health.
Privacy First
Your clinical data is sensitive. We process everything locally in your browser, ensuring total privacy. No diagnostic data is ever stored or transmitted.
Research-Grade
Powered by the CKD-EPI 2021 equation, the standard for assessing kidney function without race-based variables for equitable results.
Modern Tech
Instant renal metrics. Optimized for a fast and responsive experience on any modern mobile or desktop device with zero latency.

COMMON QUESTIONS
Frequently Asked Questions
Glomerular Filtration Rate (GFR) is a measure of how well your kidneys are filtering waste from your blood. It is considered the best overall index of kidney function.
For most healthy adults, a GFR of 90 or higher is considered normal. A GFR below 60 for three months or more may indicate chronic kidney disease (CKD).
Estimated GFR (eGFR) is highly accurate for screening but can be affected by extreme body size, pregnancy, or muscle-wasting diseases. Always discuss your results with a healthcare provider.
Creatinine is a waste product from the normal breakdown of muscle tissue. The kidneys filter creatinine from the blood, so high levels in the blood often indicate impaired kidney function.
