The Framingham Risk Score estimates the 10-year risk of developing cardiovascular disease (heart attack or stroke) based on data from the Framingham Heart Study, one of the longest-running epidemiological studies. It incorporates age, sex, total cholesterol, HDL cholesterol, systolic blood pressure, blood pressure treatment status, smoking, and diabetes.
Formula: Framingham 2008 General CVD Risk Score (sex-specific Cox regression model)
Input your age, sex, cholesterol levels, blood pressure, and risk factors. You'll need a recent lipid panel (total cholesterol, HDL) and blood pressure reading.
The algorithm uses sex-specific Cox regression models from the Framingham Heart Study to estimate your 10-year probability of a cardiovascular event.
Review whether your risk is low (<10%), intermediate (10-20%), or high (>20%), and discuss with your doctor whether lifestyle changes or medications are warranted.
Primary care physicians
Calculate cardiovascular risk during routine check-ups to identify patients who may benefit from preventive interventions or closer monitoring.
Physicians considering lipid therapy
Use the risk score to guide conversations about statin initiation. Guidelines recommend discussing statins when 10-year risk exceeds 7.5-10%.
Individuals wanting to understand risk
See your personal risk as a concrete number to motivate lifestyle changes. A 15% risk means 15 out of 100 people like you will have an event in 10 years.
Wellness coaches, dietitians
Establish a baseline risk before starting exercise programs or dietary interventions (use [TDEE Calculator](/tools/tdee-calculator) and [BMI Calculator](/tools/bmi-calculator) for weight management), then track improvement over time with repeat calculations.
Surgeons, anesthesiologists
Quantify cardiovascular risk before elective procedures to guide perioperative management and informed consent discussions.
Preventive cardiologists
Show patients how individual risk factor changes affect their score — demonstrating the impact of quitting smoking or lowering BP on projected risk.
Quitting smoking can reduce your cardiovascular risk by 50% within 1-2 years. If you smoke, this is the single most impactful modifiable risk factor — more powerful than any medication.
While non-fasting lipid panels are acceptable for screening, fasting values (8-12 hours) provide more accurate total cholesterol and triglyceride measurements for risk calculation.
High HDL (≥60 mg/dL) is protective — it's called 'good cholesterol' for a reason. Low HDL (<40 mg/dL in men, <50 in women) is an independent risk factor even with normal total cholesterol.
Hypertension on treatment is considered higher risk than the same BP level untreated. This reflects the underlying vascular damage that prompted treatment, not a penalty for taking medication.
If you've quit smoking, lost significant weight (track with [BMI Calculator](/tools/bmi-calculator) or [TDEE Calculator](/tools/tdee-calculator)), or achieved better BP or cholesterol control, recalculate your score. Improvement can happen within months and may affect treatment decisions.
For patients in the 10-20% risk range, a coronary artery calcium (CAC) score can reclassify risk. CAC of 0 downgrades risk; CAC >100 upgrades risk and supports more aggressive treatment.
Framingham doesn't include family history. If you have a first-degree relative with premature CVD (men <55, women <65), your actual risk is higher than calculated. Discuss with your doctor.
The Framingham population was primarily white. South Asians have higher CVD rates than the score predicts. Some clinicians apply a 1.5x multiplier for South Asian patients.
Having diabetes roughly doubles cardiovascular risk. Many guidelines consider diabetes a CVD risk equivalent, meaning diabetic patients are treated as if they already have heart disease.
Age drives most of the score. A 65-year-old with perfect risk factors will still have higher calculated risk than a 40-year-old smoker. This reflects the cumulative nature of cardiovascular risk.
The Framingham Risk Score is derived from the Framingham Heart Study (D'Agostino et al., Circulation 2008). Validated in multiple populations with C-statistics of 0.75-0.80 for discrimination. Endorsed by AHA/ACC and international guidelines for primary prevention risk stratification. May over- or under-estimate risk in non-white populations.
Your result is a percentage representing your estimated probability of experiencing a cardiovascular event (heart attack, stroke, or cardiovascular death) within the next 10 years. A risk below 10% is considered low, 10–20% is intermediate, and above 20% is high.
For intermediate-risk patients, the result is especially important because it often drives the conversation about whether to start preventive therapies such as statins. Current guidelines generally recommend discussing statin therapy when the 10-year risk is 7.5–10% or higher, though shared decision-making with the patient is essential.
The Framingham Risk Score is intended for primary prevention — meaning adults aged 30–79 who have not yet had a cardiovascular event (no prior heart attack, stroke, or established atherosclerotic disease). It is commonly used during routine check-ups, annual physicals, or when a patient has newly identified risk factors like elevated cholesterol or hypertension.
It is a good starting point for risk-stratification conversations and can motivate patients to make lifestyle changes by putting their risk into concrete, understandable terms.
The Framingham Risk Score was derived primarily from a white American population in Framingham, Massachusetts. It may overestimate risk in some populations (e.g., Japanese, Spanish) and underestimate risk in others (e.g., South Asian, Indigenous Australian). The ACC/AHA Pooled Cohort Equations (ASCVD Risk Calculator) may be more appropriate for racially diverse populations.
The score does not incorporate family history of premature CVD, C-reactive protein, coronary artery calcium scores, or other emerging risk markers. It also does not account for the duration or intensity of risk factor exposure — a lifelong smoker and a recent starter receive the same points.
Patients with existing cardiovascular disease should not use this calculator, as they are already in a high-risk category requiring secondary prevention strategies.
