Check your type 2 diabetes risk factors in a minute. This free diabetes risk calculator scores common factors like age, family history, blood pressure and BMI – a prompt to talk to your doctor, not a diagnosis.
Based on common risk factors used in public screening tools. A higher score means it’s worth talking to a doctor – many people with raised risk feel completely well. Type 1 diabetes and other forms aren’t captured here.
How the Diabetes Risk Calculator Works
The Diabetes Risk Calculator scores common risk factors for type 2 diabetes — age, sex, family history, blood pressure history, activity level and BMI — into a single number. It’s a risk-awareness screener modeled on common public screening approaches, not a diagnostic test: only a blood test ordered by a doctor can confirm diabetes or prediabetes.
Formula: BMI = Weight (kg) ÷ (Height (m))^2, where Height (m) = Height (cm) ÷ 100. BMI points: BMI < 25 → 0, BMI < 30 → 1, BMI < 40 → 2, BMI ≥ 40 → 3. Total score = Age points + Sex points + Family-history points + Blood-pressure points + Activity points + BMI points. A total score of 5 or higher shows "Higher risk indicated"; below 5 shows "Lower risk indicated."
- Age — under 40 = 0 points, 40–49 = 1, 50–59 = 2, 60+ = 3
- Sex at birth — male = 1 point, female = 0
- Family history (parent/sibling with diabetes) — yes = 1 point, no = 0
- Blood pressure history (ever told you have high blood pressure) — yes = 1 point, no = 0
- Physical activity — active = 0 points, not active = 1 point
- Height (cm) and Weight (kg) — used to compute BMI, which adds 0–3 points to the score
Example Scenarios
| Risk Factors (Age, Sex, Family Hx, BP Hx, Activity) | Height / Weight | BMI | Total Score | Result |
|---|---|---|---|---|
| 40–49, Male, No, No, Active | 170 cm / 80 kg | 27.7 | 3 | Lower risk indicated |
| 60+, Female, Yes, Yes, Inactive | 160 cm / 90 kg | 35.2 | 8 | Higher risk indicated |
| Under 40, Male, No, No, Active | 180 cm / 75 kg | 23.1 | 1 | Lower risk indicated |
| 50–59, Female, Yes, No, Inactive | 165 cm / 70 kg | 25.7 | 5 | Higher risk indicated |
| 40–49, Female, No, Yes, Active | 155 cm / 95 kg | 39.5 | 4 | Lower risk indicated |
| 60+, Male, Yes, Yes, Inactive | 175 cm / 110 kg | 35.9 | 9 | Higher risk indicated |
What to Do After Using the Diabetes Risk Calculator
A diabetes risk calculator estimates likelihood from risk factors; it does not measure your blood sugar. A low score is reassuring but not a guarantee, and a high score is a reason to get tested, not a diagnosis.
- Diagnosis relies on blood tests, usually HbA1c, fasting plasma glucose or an oral glucose tolerance test, arranged by your doctor, not by a diabetes risk calculator.
- Mention any history of gestational diabetes or polycystic ovary syndrome to your doctor, even if the diabetes risk calculator does not ask about it.
Age and family history are fixed, but other factors can change. Regular physical activity, losing some weight if you carry excess, and eating more fiber and fewer sugary drinks all lower type 2 risk over time. Rerun the diabetes risk calculator after a few months of changes to see how your score moves.
See a doctor soon if you have extreme thirst, frequent urination, unexplained weight loss or blurred vision, whatever the diabetes risk calculator says. The type 2 diabetes article on Wikipedia explains the condition and its risk factors in more depth.
Diabetes Risk Calculator FAQ
Can this calculator diagnose diabetes or prediabetes?
No. It cannot tell you whether you have diabetes or prediabetes — only a blood test can. This tool estimates general risk factors as a prompt to talk with a healthcare professional, not as a diagnosis.What counts as a “higher risk” score?
A total score of 5 or higher is flagged as “Higher risk indicated” in this tool. That doesn’t mean you have diabetes — it means enough common risk factors are present that a simple blood-sugar test is worth discussing with your doctor.Does this tool work for Type 1 diabetes?
No. It’s built around risk factors for type 2 diabetes specifically — age, weight, activity, family history and blood pressure. Type 1 diabetes and other forms aren’t captured by this scoring model.Why does BMI count toward the score?
Higher BMI is one of several factors associated with type 2 diabetes risk in common screening tools, so it contributes up to 3 points here, calculated from the height and weight you enter.I have several risk factors but feel fine — should I still get tested?
Many people with raised risk factors feel completely well, since early blood-sugar changes often have no noticeable symptoms. A higher score is exactly the kind of situation where a doctor’s blood test is worth asking about.What should I do if my score comes back high?
Treat it as a starting point for a conversation, not a verdict. Bring your results to a doctor, who can order an appropriate blood test and interpret it alongside your full health history.Related Calculators
Since BMI is part of this score, the BMI calculator and waist to hip ratio calculator can add useful context to your result. Pair this with the blood sugar level checker if you already have a recent glucose reading to review.
