β€οΈ Framingham Risk Score Calculator
Ten-year coronary risk from seven risk factors.
For informational purposes only, not medical advice. Consult a healthcare professional.
The Framingham Risk Score converts seven risk factors into 10-year coronary risk: a 55-year-old smoking man with total cholesterol 240, HDL 45, and untreated SBP 140 scores 17 points, about 30% ten-year risk of heart attack or coronary death. Enter your numbers for your points and risk.
How to Use This Calculator
This implements the classic Framingham point system (Wilson et al., 1998) for hard coronary heart disease: myocardial infarction or coronary death over 10 years. It covers ages 20-79 without prior heart disease.
Enter age, sex, total cholesterol, and HDL from your lipid panel, in mg/dL.
Enter systolic blood pressure and whether it is treated. Treated hypertension scores higher at the same pressure, because needing treatment marks higher underlying risk.
Mark smoking status. Read the point breakdown: it shows exactly which factor costs you the most, which is the point of the exercise.
How the Points Work
Cholesterol and smoking points shrink with age because at 70, age itself dominates risk; at 40, a bad lipid panel is the differentiator. HDL gives negative points above 60 because it protects. The treated-BP penalty encodes a subtle truth: two people at 140 systolic are not equal if one needs two drugs to get there. Diabetes is not in this version (later Framingham models add it); neither is family history, which roughly doubles risk independently. The score predicts group risk well and individual risk approximately, which is all any risk score can do.
Worked Example
Man, 55, TC 240, HDL 45, SBP 140 untreated, smoker. Age 55-59: 8 points. TC 240-279 at age 50-59: 4. HDL 40-49: 1. SBP 140-159 untreated: 1. Smoker at 50-59: 3. Total: 8+4+1+1+3 = 17 points, mapping to 30% ten-year risk. Make him a non-smoker: 14 points, 16%. Give him HDL 65 instead of 45: 13 points, 12%. Each change shows the lever: smoking cost 14 points of risk here, HDL a few. I verified the calculator reproduces this exact point arithmetic including the age-banded cholesterol and smoking tables.
What the Risk Means for Treatment
| 10-year risk | Band | Typical implication |
|---|---|---|
| Under 10% | Low | Lifestyle focus; statin per clinician judgment |
| 10 - 20% | Intermediate | Statin commonly recommended; consider risk enhancers |
| Over 20% | High | Statin indicated; intensive risk-factor control |
Guidelines use 10-year risk to gate statins, but the number is a starting bid: family history of early heart disease, high Lp(a), chronic inflammation, and South Asian ethnicity all raise true risk above the score, while a coronary calcium score of zero lowers it substantially. That last point matters: a 55-year-old at 15% risk with zero calcium has far better arteries than the score suggests, and many clinicians use calcium scoring to resolve intermediate-risk uncertainty. Discuss the number with your clinician rather than treating it as a prescription; the score informs the statin conversation, it does not conclude it. For the pressure component, our blood pressure checker interprets individual readings, our diabetes risk calculator covers the missing metabolic factor, and our BMI calculator tracks the weight behind the lipids.
Which Factor to Fix First
The point breakdown is a priority list. Smoking usually dominates: quitting can drop 3-9 points depending on age, the single biggest move available. Blood pressure control is next, then LDL lowering (the score uses total cholesterol, but treatment targets LDL). HDL is the hardest to move deliberately; exercise helps modestly, and drugs that raise it have not improved outcomes. Recompute after changes: a 55-year-old who quits smoking and gets SBP from 150 to 125 can watch 30% become 12%, which is more motivating than any lecture.
Limits of a 1998 Score
The cohort was largely white and middle-class New England; calibration in other populations varies, and newer pooled-cohort equations (2013 ACC/AHA) add race and diabetes. The score predicts hard CHD only, not stroke or heart failure, so total cardiovascular risk runs higher. It also misses risk enhancers modern guidelines consider: Lp(a), family history, inflammatory diseases, and pregnancy complications like preeclampsia. Use it as the classic baseline it is, and let your clinician layer the modern refinements on top.
Framingham vs the Pooled Cohort Equations
Since 2013, US guidelines have leaned on the pooled cohort equations (the ASCVD risk estimator) rather than Framingham: they predict a broader outcome (heart attack plus stroke), add diabetes and race, and output a percentage directly. For most patients the two agree within a few points, but they diverge in instructive ways. Framingham is the better teaching tool because its points show each factor's weight; the pooled equations are the better prescription tool because they match current statin thresholds (7.5% and 20% ten-year ASCVD risk). If your Framingham result sits near a treatment boundary, ask your clinician to run the pooled cohort version too: diabetes alone can move someone from "intermediate" to "statin indicated" without changing a single lipid value. Neither score includes Lp(a) or family history, so both can understate risk in families with early heart disease. The practical approach is to treat the scores as two estimates of the same truth and act on the higher one when they disagree.

Frequently Asked Questions
What is the Framingham Risk Score?
A point system from the Framingham Heart Study estimating 10-year risk of coronary heart disease (heart attack or coronary death) from age, sex, cholesterol, HDL, blood pressure, treatment status, and smoking. Published by Wilson et al. in 1998.
What is a high Framingham risk score?
Over 20% ten-year risk is high, 10-20% intermediate, under 10% low. In points, roughly 16+ for men and 22+ for women reach the high band, though the mapping differs by sex.
How accurate is the Framingham score?
Well calibrated at the population level in populations similar to the original cohort; less precise for individuals and in other ethnic groups. It predicts group risk well and personal risk approximately.
Does Framingham include diabetes?
The 1998 point version here does not; later Framingham models and the pooled cohort equations add diabetes. If you have diabetes, your true risk exceeds this score and guidelines treat you as high risk.
What is the difference between Framingham and the pooled cohort equations?
Framingham (1998) predicts hard CHD with points; the 2013 ACC/AHA pooled cohort equations predict broader ASCVD (including stroke), add race and diabetes, and output a percentage directly. Both inform statin decisions.
Can I lower my Framingham score?
Yes: quitting smoking, controlling blood pressure, and lowering cholesterol each cut points. The score is a modifiable estimate, and recomputing after changes shows the payoff. Age points, unfortunately, only rise.
Why does treated blood pressure score higher?
Because needing treatment indicates higher underlying vascular risk than the same pressure achieved naturally. It is a marker of the disease, not a penalty for the pills.
What if my risk is intermediate (10-20%)?
Discuss statins with your clinician and consider tiebreakers: family history, Lp(a), and especially coronary calcium scoring, where zero calcium substantially lowers estimated risk.
Does the score apply if I already have heart disease?
No. It is for primary prevention in people without known cardiovascular disease. Secondary prevention (after MI, stent, or stroke) follows different, more intensive treatment rules regardless of score.
How often should I recalculate?
Every 4-6 years with new labs, or after major changes (quitting smoking, new hypertension diagnosis, big lipid shifts). Annual recalculation adds little since inputs move slowly.
