The Framingham Risk Score is one of the most widely used methods to estimate a person’s 10-year cardiovascular disease (CVD) risk. Use the calculator below to get a quick estimate based on age, cholesterol, blood pressure, smoking status, and diabetes.
Framingham 10-Year CVD Risk Calculator
Intended for adults. Most validated for ages 30 to 79 years. Units are mg/dL for cholesterol and mmHg for blood pressure.
What is the Framingham score?
The Framingham score estimates your chance of developing cardiovascular disease over the next 10 years. It comes from long-term population research and uses practical clinical values that are commonly available in routine care.
In this version, the risk model includes:
- Age
- Sex
- Total cholesterol
- HDL cholesterol
- Systolic blood pressure
- Whether blood pressure is being treated
- Smoking status
- Diabetes status
How to interpret your result
Your result is a 10-year percentage risk of a cardiovascular event. A common rule-of-thumb interpretation is:
- Less than 10%: lower risk
- 10% to 19.9%: intermediate risk
- 20% or higher: higher risk
Risk categories are helpful for conversation, not labels. Your clinician may combine this score with family history, kidney disease, inflammatory conditions, medication tolerance, and other factors before recommending treatment.
Why this calculator matters
Most people don’t feel symptoms until cardiovascular disease has already advanced. A structured risk estimate can help identify problems early and guide prevention strategies such as nutrition changes, exercise, blood pressure optimization, smoking cessation, and lipid management.
What can improve your score over time?
- Stop smoking completely
- Lower systolic blood pressure through lifestyle and medication when needed
- Improve cholesterol profile (lower non-HDL, raise HDL where possible)
- Control blood sugar if you have diabetes
- Maintain healthy sleep, weight, and activity patterns
A practical prevention checklist
1) Blood pressure
Track your home blood pressure regularly, especially if readings are borderline in the clinic. Small sustained improvements can significantly reduce long-term risk.
2) Lipids
Review your full lipid panel, not only total cholesterol. Discuss ApoB, non-HDL cholesterol, and triglycerides with your clinician when appropriate.
3) Smoking and nicotine
Smoking is one of the strongest modifiable drivers in risk models. Quitting has a meaningful, measurable effect on future risk.
4) Diabetes and metabolic health
If you have diabetes or prediabetes, early glucose management can change cardiovascular outcomes over time.
Limitations of the Framingham score
No calculator is perfect. Framingham is population-based, so individual results can vary. It may overestimate or underestimate risk in some ethnic groups or in people with unusual risk profiles. It also does not directly include factors such as:
- Family history of premature cardiovascular disease
- Chronic kidney disease severity
- Inflammatory disorders
- Coronary artery calcium score
- Diet quality, fitness level, and stress burden
Use this score as a starting point for informed decisions, not as a final diagnosis.
FAQ
Is this the same as a heart attack calculator?
Not exactly. This version estimates broader cardiovascular risk, which may include multiple event types, not only heart attack.
Can I use SI units (mmol/L) for cholesterol?
This calculator expects mg/dL. If your report is in mmol/L, convert before entering values.
Should I change medication based only on this score?
No. Medication decisions should be made with a licensed clinician who can assess your full medical picture.
