What it calculates
The “Kidney Failure Risk” calculator computes 5-year kidney failure risk in % from 5 parameters: age (years), male sex (1 = yes), egfr (mL/min/1.73 m²), urine albumin-to-creatinine ratio (acr) (mg/g), north america (1 = yes).
Used by professionals and patients to assess health metrics, dosages, and risks.
Example calculation
With parameters Age = 60 years, Male sex (1 = yes) = 1, eGFR = 30 mL/min/1.73 m², Urine albumin-to-creatinine ratio (ACR) = 300 mg/g, North America (1 = yes) = 0 the result is 20.86 % (For adults with CKD stage 3–5 (eGFR < 60)).
How to use
- Enter age, male sex (1 = yes), egfr, urine albumin-to-creatinine ratio (acr) and north america (1 = yes) — each field above is adjustable with a slider.

FAQ
How is BMI calculated?
BMI = weight (kg) / height (m)². Example: 70 kg / (1.75 m)² = 22.9. The WHO normal range is 18.5–24.9; below that is underweight, 25–29.9 is overweight, and 30+ is obese.
Is BMI accurate for everyone?
No. BMI does not distinguish muscle from fat, so athletes may show a high BMI with low body fat. It is also less reliable for teenagers, pregnant people, older adults, and very tall or short individuals.
What are the BMI categories?
Underweight: below 18.5. Normal: 18.5–24.9. Overweight: 25–29.9. Obese class I: 30–34.9; class II: 35–39.9; class III: 40+.
What is a better measure than BMI?
Body fat percentage, waist-to-height ratio (aim for under 0.5), and waist circumference give a clearer picture of health than BMI alone.
