Heart Score Calculator
Free Health & Medical
Calculators
Explore transparent calculators for cardiovascular risk, fitness, body composition and everyday health. The featured tool on this page estimates 10-year ASCVD risk with the legacy 2013 ACC/AHA Pooled Cohort Equations for eligible adults.
The featured calculator below uses the 2013 PCE, not PREVENT™. Current ACC/AHA guidance uses PREVENT for primary-prevention risk assessment. For a current clinical estimate, use the official ACC estimator or speak with a qualified healthcare professional.

Quick answer: Heart Score Calculator is a free calculator hub. Its featured 2013 PCE tool uses age, sex, cholesterol, systolic blood pressure, treatment status, smoking and diabetes to estimate 10-year ASCVD risk for adults age 40–79 without established cardiovascular disease.
Featured: 10-Year ASCVD Risk
Published PCE LogicPrimary prevention only. This calculator is not intended for people with established ASCVD, including a previous heart attack or stroke. Ask a qualified clinician which assessment applies to you.
Risk equations can overestimate or underestimate risk for an individual. This result is an educational estimate, not a diagnosis or treatment recommendation.
For some people with an uncertain treatment decision, a clinician may consider a coronary artery calcium (CAC) scan as part of the broader assessment. A scan is not appropriate for everyone.
These factors are not captured by the formula but can push your actual risk higher. Tell your doctor if any apply.

“Heart score” can refer to different clinical tools
This page features a preventive ASCVD risk estimate. The emergency-department HEART Score uses History, ECG, Age, Risk factors and Troponin for patients with chest pain. European HeartScore/SCORE2 and heart-failure models are also separate tools. Do not use one score in place of another.
Formula name, source, intended population and input limits are shown with each calculator.

How to Interpret Your Heart Risk Score?
Your result represents the statistical probability of experiencing a cardiovascular event — a heart attack or stroke — within the next 10 years. Cardiologists classify this into four categories to guide treatment decisions.
| Risk Level | Score Range | What to Do |
|---|---|---|
| 🟢 Low | < 5% | Maintain healthy habits. Annual check-up. |
| 🟡 Borderline | 5% – 7.4% | Review risk enhancers and options with a clinician. |
| 🟠 Intermediate | 7.5% – 19.9% | A clinician-patient risk discussion is appropriate. |
| 🔴 High | ≥ 20% | Arrange a clinical review of overall cardiovascular risk. |
A calculated percentage is not a diagnosis. Treatment decisions require a clinician-patient discussion that considers medical history, risk enhancers, potential benefits and harms, and personal preferences.
The Science Behind the ASCVD Risk Estimator
The Atherosclerotic Cardiovascular Disease (ASCVD) risk score is built on the Pooled Cohort Equations described by Goff and colleagues in the ACC/AHA cardiovascular-risk assessment report. The equations were derived from multiple population cohorts.
The formula combines multiple variables — age, sex, race, lipid profile, blood pressure, smoking status, and diabetes — using a Cox proportional hazards model. This produces a probability that accounts for complex interactions between risk factors rather than treating each one in isolation.

Understanding Systolic Blood Pressure
Systolic blood pressure — the top number in a reading — reflects arterial pressure while the heart contracts. Blood-pressure categories and treatment targets depend on the guideline and the individual; see the American Heart Association blood-pressure resources and discuss your readings with a clinician.
The Role of HDL vs. LDL Cholesterol
HDL (high-density lipoprotein) is often called "good cholesterol" because it transports lipids away from the arteries toward the liver for excretion. LDL (low-density lipoprotein), by contrast, deposits cholesterol in arterial walls, contributing to atherosclerotic plaque buildup. The ASCVD formula uses total cholesterol and HDL together because their ratio offers a more precise risk signal than either number alone.
Research published via Mayo Clinic's cardiovascular resources consistently links low HDL levels (below 40 mg/dL in men, below 50 mg/dL in women) with significantly elevated arterial disease risk.
Key Factors That Influence Your Heart Health
Current smoking is a direct input in the PCE and is associated with higher cardiovascular risk. The model treats smoking status as yes or no.
Diagnosed diabetes is a direct input in the PCE and can materially change the estimate. The tool does not use glucose or HbA1c values.
Being on antihypertensive medication is itself a risk signal — it means BP was high enough to require intervention. The ASCVD model accounts for this directly.
The 2013 PCE uses age, sex and race-specific coefficients. This is a limitation of the legacy model; the newer PREVENT equations do not use race.
