Framingham Risk Score Calculator (10-Year CVD)
Estimate your 10-year risk of cardiovascular disease with the Framingham general CVD risk score (D’Agostino 2008). It combines age, cholesterol, blood pressure, smoking and diabetes into a single percentage covering heart attack, stroke, heart failure and peripheral artery disease. It is intended for adults aged 30–74 without known cardiovascular disease. Cholesterol is entered in mg/dL.
About the Framingham general CVD score
This uses the sex-specific 2008 general cardiovascular risk functions: 10-year risk = 1 − S₀^exp(Σβx − mean), with S₀ = 0.88936 (men) or 0.95012 (women) and log-transformed terms for age, total and HDL cholesterol, systolic blood pressure (treated or untreated), smoking and diabetes.

Frequently asked questions
What is the Framingham risk score?
The Framingham risk score is a 10-year prediction of cardiovascular disease derived from the Framingham Heart Study. This calculator uses the 2008 “general CVD” model by D’Agostino and colleagues, which predicts coronary heart disease, stroke, heart failure and peripheral artery disease combined from age, total and HDL cholesterol, systolic blood pressure (and whether it is treated), smoking and diabetes. The result is your estimated probability of a first cardiovascular event over the next decade.
What counts as low, intermediate or high risk?
A 10-year risk under 10% is generally considered low, 10–20% is intermediate, and 20% or above is high. These thresholds guide conversations about lifestyle changes and preventive treatment, but the cut-offs and the treatment decisions themselves are set by clinical guidelines and your doctor. This calculator applies those same three bands and flags a result when the age falls outside the validated 30–74 range. Because age carries a great deal of weight in the model, older adults reach the higher bands with fewer modifiable risk factors — which is why the percentage is read next to what can actually be changed.
Who is the score valid for?
The model was developed for adults roughly 30–74 years old who do not already have cardiovascular disease or diabetes-related vascular disease. It is less reliable outside that age range, and modern guidelines in many countries now use the Pooled Cohort Equations or region-specific tools such as QRISK or SCORE2. Use this as an educational estimate.
My cholesterol is in mmol/L — how do I enter it?
Multiply mmol/L by 38.67 to get mg/dL for both total and HDL cholesterol. For example, a total cholesterol of 5.0 mmol/L is about 193 mg/dL, and an HDL of 1.3 mmol/L is about 50 mg/dL. Enter the mg/dL figures.
Does a high score mean I will have a heart attack?
A high Framingham score does not mean a heart attack is coming. The score is a population-based probability, not a certainty or a diagnosis. Two people with the same score can have very different outcomes, and the estimate does not capture family history, ethnicity, kidney disease or other factors your clinician weighs. Treat it as a prompt to discuss prevention, not a verdict.
This is a reference tool, not a diagnosis or medical advice. Results depend on the laboratory, assay and clinical context, and reference intervals vary between labs and by age and sex — always read your result against the range printed on your own report and discuss it with a qualified healthcare professional.
