Diabetes Risk Calculator
Type 2 diabetes affects more than 38 million Americans and is largely preventable. This tool uses an ADA-inspired risk scoring approach to estimate your personal risk based on key factors: age, body weight (BMI), family history, physical activity, blood pressure, and history of gestational diabetes. Early awareness is the first step toward prevention.
Quick Answer
A score of 5 or higher on this ADA-inspired risk tool indicates high risk for type 2 diabetes and warrants a conversation with your doctor about blood glucose testing.
These results are estimates based on general formulas and are not a substitute for professional medical advice. Consult a healthcare provider before making health decisions.
How the Formula Works
Enter your age bracket. Points are assigned based on increasing risk with age: 0 points for under 40, 1 for 40–49, 2 for 50–59, and 3 for 60 and older.
Age score: 0 (< 40) | 1 (40–49) | 2 (50–59) | 3 (60+)Enter your height and weight. Your BMI is calculated and scored: 0 points for BMI under 25, 1 for 25–29, 2 for 30–39, and 3 for 40 or above.
BMI = weight (kg) ÷ height (m)²Answer yes/no questions for each risk factor. Each "yes" adds 1 point: family history of type 2 diabetes, physical inactivity (< 3 times/week), history of high blood pressure, and history of gestational diabetes.
All points are summed to produce your total risk score. Categories: Low Risk (0–2), Moderate Risk (3–4), High Risk (5+).
Total score = age score + BMI score + risk factor points
Methodology & Sources
Reviewed and updated April 5, 2026 · Prepared by GetHealthyCalculators Editorial Team
This calculator is based on the American Diabetes Association (ADA) risk test framework and CDC prediabetes risk factors. It is designed as an educational screening tool and uses validated population-level risk factors. It does not assess blood glucose levels directly.

How to Interpret Your Results
Your score is classified into three risk tiers. A low score does not guarantee you will not develop diabetes, but it means you currently carry fewer known risk factors. A high score is not a diagnosis — it is a call to action to speak with a healthcare provider about proper blood glucose testing.
- Low Risk
- 0–2 — Few known risk factors present. Continue healthy habits and maintain routine check-ups.
- Moderate Risk
- 3–4 — Several risk factors are present. Consider discussing diabetes screening with your doctor.
- High Risk
- 5–100 — Multiple significant risk factors present. A healthcare provider visit and blood glucose test are strongly recommended.
Limitations
- IMPORTANT: This tool is for educational purposes only and does not constitute medical advice. It does not replace a clinical evaluation or blood glucose test.
- This calculator does not measure blood sugar levels. Only a fasting plasma glucose, oral glucose tolerance test, or HbA1c performed by a healthcare provider can diagnose diabetes or prediabetes.
- Risk factors not captured here — such as ethnicity, polycystic ovary syndrome (PCOS), and certain medications — can also elevate risk.
- This tool applies to adults aged 18 and older. Risk assessment for children and adolescents requires different clinical criteria.
- A low score does not rule out diabetes. If you have symptoms such as excessive thirst, frequent urination, or unexplained fatigue, consult a doctor regardless of your score.
