This free online framingham risk score calculator provides instant results with no signup required. All calculations run directly in your browser — your data is never sent to a server. Enter your values below and see results update in real time as you type. Perfect for everyday calculations, homework, or professional use.
How to Use This Calculator
Enter your input values
Fill in all required input fields for the Framingham Risk Score Calculator. Most fields include unit selectors so you can work in your preferred unit system — metric or imperial, whichever matches your problem.
Review your inputs
Double-check that all values are correct and that you have selected the right units for each field. Incorrect units are the most common source of calculation errors and can produce results that are off by factors of 2, 10, or more.
Read the results
The Framingham Risk Score Calculator instantly computes the output and displays results with units clearly labeled. All calculations happen in your browser — no loading time and no data sent to a server.
Explore parameter sensitivity
Try adjusting individual input values to see how the output changes. This is a quick and effective way to develop intuition about how different parameters influence the result and to identify which inputs have the largest effect.

All calculations are performed locally in your browser — no personal health data is transmitted or stored.
About Framingham Risk Score Calculator
The Framingham Risk Score Calculator provides a simplified estimate of your 10-year risk for developing cardiovascular disease (heart attack or stroke). Based on the landmark Framingham Heart Study — the longest-running cardiovascular epidemiological study, begun in 1948 in Framingham, Massachusetts — this tool assesses traditional risk factors including age, sex, blood pressure, cholesterol levels, smoking, and diabetes. The calculator uses a point-based scoring system that approximates the original logistic regression models. It is intended for educational risk awareness, not clinical decision-making.
The Math Behind It
Formula Reference
Framingham Risk Score (Simplified)
Risk Points = Age + Cholesterol + HDL + BP + Smoking + Diabetes points
Variables: Point-based scoring system; total points map to 10-year risk percentage
Worked Examples
Example 1: Moderate Risk Male
55-year-old male, SBP 140, total chol 220, HDL 45, non-smoker, non-diabetic
Estimated 10-year CVD risk: ~19.5% — moderate-to-high. Statin therapy and lifestyle modifications recommended.
Example 2: Low Risk Female
45-year-old female, SBP 118, total chol 190, HDL 65, non-smoker, non-diabetic
Estimated 10-year CVD risk: ~6% — low risk.
Common Mistakes & Tips
- !Using this simplified educational model for clinical decision-making. The ACC/AHA Pooled Cohort Equations are the current clinical standard.
- !Ignoring that the Framingham study population was predominantly white. The model may over- or under-estimate risk in other ethnicities.
- !Treating the score as a precise prediction. It provides a population-level estimate; individual risk may differ substantially.

Frequently Asked Questions
What is a good Framingham risk score?
A 10-year risk below 10% is considered low. 10-20% is intermediate. Above 20% is high risk, generally warranting statin therapy and aggressive lifestyle modification. Below 7.5% is where current ACC/AHA guidelines consider statin benefit less certain.
Can I lower my Framingham risk score?
Yes. Smoking cessation, blood pressure control, cholesterol management (statins reduce LDL 30-50%), exercise, weight loss, and diabetes control can all significantly reduce your calculated risk. Quitting smoking alone can reduce risk by 50% within 5 years.
Why is this simplified and not the full Framingham model?
The original model uses continuous variables and logarithmic Cox regression coefficients that are complex to implement in a simple calculator. This point-based approximation captures the key relationships while being transparent and educational. For clinical use, ask your doctor to calculate your ASCVD risk using the Pooled Cohort Equations.
