Heart Disease Risk Calculator

Q: What is a Framingham Risk Score?

The Framingham Risk Score is a 10-year cardiovascular disease risk estimate developed from the Framingham Heart Study — one of the longest-running cardiovascular cohort studies in medical history, started in 1948. It assigns points to key risk factors including age, sex, cholesterol, blood pressure, smoking, and diabetes, then maps the total to a probability of experiencing a heart attack or stroke within the next decade.

Q: What is a "good" 10-year heart disease risk score?

A 10-year CVD risk below 10% is considered low. Risk between 10–20% is moderate, and above 20% is high. Most cardiovascular prevention guidelines target a risk below 7.5–10% as the threshold where the benefits of statin therapy begin to clearly outweigh risks. However, any risk level benefits from healthy lifestyle habits.

Q: What is the difference between total cholesterol and HDL cholesterol?

Total cholesterol is the sum of all cholesterol types in your blood, including LDL ("bad"), HDL ("good"), and VLDL. HDL cholesterol specifically refers to high-density lipoprotein, which transports cholesterol away from arteries back to the liver — higher HDL is protective. Your doctor can measure both with a standard lipid panel blood test.

Q: Why does being on blood pressure medication increase my risk score?

The Framingham scoring methodology assigns higher points to the same blood pressure reading when a person is on antihypertensive medication, because the medication use itself signals a history of elevated blood pressure. It does not mean the medication is harmful — in fact, well-controlled blood pressure on medication significantly reduces event risk compared to uncontrolled hypertension.

Q: Can I lower my 10-year cardiovascular risk?

Yes. Studies consistently show that quitting smoking (largest single modifiable impact), lowering LDL cholesterol, reducing blood pressure, managing blood glucose in diabetes, and increasing physical activity can substantially reduce 10-year CVD risk. Statin therapy in moderate-to-high-risk individuals reduces risk by approximately 25–35% relative.

Q: Should I use this result to stop or change my medications?

No. This calculator is for educational awareness only. Never start, stop, or change prescription medications based on this tool alone. Always consult your doctor or cardiologist before making any changes to a prescribed treatment plan.

Q: How is this different from the ACC/AHA Pooled Cohort Equations?

The ACC/AHA Pooled Cohort Equations (PCE), introduced in 2013 US guidelines, extend the Framingham model by incorporating race/ethnicity data and using atherosclerotic CVD (ASCVD) as the outcome rather than only coronary heart disease. The PCE is the current clinical standard in the US. This calculator uses a Framingham-based simplified model, which is useful for education and awareness but should not replace a PCE calculation done by your healthcare provider.

Cardiovascular disease (CVD) remains the leading cause of death worldwide, yet it is largely preventable. The Framingham Heart Study pioneered a risk scoring approach that allows clinicians and patients to estimate the probability of a heart attack or stroke over the next 10 years based on modifiable and non-modifiable risk factors. This calculator uses a simplified version of that framework, combining age, sex, total and HDL cholesterol, systolic blood pressure, blood pressure medication use, smoking, and diabetes into a single point total that maps to a percentage risk. Understanding your risk score empowers you to have targeted conversations with your doctor and take evidence-based preventive action.

Quick Answer

A 10-year CVD risk below 10% is considered low, 10–20% is moderate, and above 20% is high. The most impactful modifiable factors are smoking cessation, blood pressure control, and cholesterol management.

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

Assign age points based on sex-specific Framingham tables (e.g., a 55-year-old male earns 8 points; a 55-year-old female earns 8 points).
Add total cholesterol points based on your reading in mg/dL — lower cholesterol reduces your point score.
< 160 mg/dL = −3 pts (male) | 200–239 mg/dL = 4 pts | ≥ 280 mg/dL = 11 pts
Add HDL cholesterol points — higher HDL ("good cholesterol") reduces your score.
≥ 60 mg/dL = −1 pt | 45–49 mg/dL = +1 pt | < 35 mg/dL = +5 pts
Add systolic blood pressure points — being on blood pressure medication increases the point weight for the same reading.
Add smoking points (male +4, female +3) and diabetes points (male +3, female +4) if applicable.
Sum all points and map the total to a sex-specific 10-year risk percentage using the Framingham lookup table.
Risk % = PointsToRisk(totalPoints, sex)

Methodology & Sources

Reviewed and updated April 5, 2026 · Prepared by GetHealthyCalculators Editorial Team

This calculator implements a simplified version of the Framingham Risk Score (FRS) originally published by Wilson et al. (1998) and updated in subsequent editions. Sex-specific point tables are used for age, total cholesterol, HDL cholesterol, and systolic blood pressure. The model is intentionally conservative and does not include newer biomarkers such as hsCRP, coronary calcium score, or ApoB. For clinical decision-making, the ACC/AHA Pooled Cohort Equations (2013) are the current guideline-recommended tool in the United States.

Limitations

This is an educational estimate based on a simplified Framingham model — it is not a clinical diagnostic tool.
The calculator does not account for family history, ethnicity-specific risk adjustments, or newer biomarkers such as hsCRP or coronary artery calcium score.
The Framingham score was originally developed in a predominantly White, middle-class American population and may underestimate or overestimate risk in other groups.
Results should be interpreted together with a qualified healthcare provider who can incorporate your full medical history.
Inputs are self-reported — small inaccuracies in cholesterol or blood pressure values can meaningfully shift the risk estimate.
