eGFR Calculator

The estimated Glomerular Filtration Rate (eGFR) is the best measure of kidney function. An eGFR result is provided following a serum creatinine test.

To calculate the rate, insert the relevant results here and then click on the ‘Calculate’ button.




This calculator uses the CKD-EPI formula. Some pathology results may use an alternate formula, which will result in a slightly different result.

For more information on the eGFR readings, refer to:

Please note the calculator is not valid for people under the age of 18.

‘CKD - GO!’ app

CKD - Go! is an app to help doctors recognise, understand and manage chronic kidney disease

It allows you to view a personalised action plan, based on the eGFR and urine albumin creatinine ratio.

App development
Action plans and staging criteria used in this app have been adapted from the handbook ‘Chronic Kidney Disease Management in General Practice’ produced by Kidney Health Australia.

CKD - Go! was created by Dr Priyanka Sagar and Dr Angus Ritchie of Concord Repatriation General Hospital (NSW). Dr Sagar and Dr Ritchie received non-financial support from Kidney Health Australia and no external funding contributed to the development of the app. The authors have no conflicts of interest to declare.

The CKD - Go! app can now be downloaded free from the iTunes Store and Google Play.

This app is based on the best information available at the time of publication. It is designed to provide information and assist decision-making. It is not intended to indicate an exclusive course of action, or serve as a standard of medical care. Variations, taking individual circumstances into account, may be appropriate.

Each healthcare professional making use of this app is responsible for evaluating the appropriateness of applying it in the setting of any particular clinical situation. The authors assume no responsibility for personal or other injury, loss or damage that may result from the information in the app.

QKidney® risk calculator

Many health professionals conduct assessments with the public to help assess their risk of developing kidney disease. The QKidney® risk calculator can be a helpful tool to assist with these assessments. 

QKidney® risk calculator can be accessed free at qkidney.org or as an iPhone or iPad app

You can use this calculator to assess the risk of developing moderate-severe kidney disease over the next five years by answering some simple questions. 

The QKidney® algorithms are based on routinely collected data from many thousands of general practices across the United Kingdom who have contributed data to the QResearch database for medical research. 

The calculator requires height, weight and systolic blood pressure measures as well as responses to a few questions that relate to risk factors for chronic kidney disease. It is a great educational tool as people will learn what factors increase their risk of developing chronic kidney disease. 

Documents to assist the use of the calculator
Kidney Health Australia has developed some documents to assist health professionals to conduct QKidney® assessments, including:
