About This Tool

The Blood Pressure Risk Calculator helps you understand your blood pressure reading by classifying it according to the 2017 AHA/ACC guidelines. It considers your systolic and diastolic values, resting pulse, age group, and additional cardiovascular risk factors to provide a comprehensive risk assessment.

High blood pressure (hypertension) is a major risk factor for heart disease, stroke, kidney disease, and other serious conditions. Regular monitoring and early detection are key to effective management. Pair this tool with our Resting Heart Rate Fitness Score to get a more complete cardiovascular health picture, or check your Body Fat Percentage and Waist-to-Hip Ratio — both of which are closely linked to blood pressure health.

Frequently Asked Questions (FAQ)

What do systolic and diastolic blood pressure numbers mean?
Systolic pressure (the top number) measures the force when your heart beats. Diastolic pressure (the bottom number) measures the force when your heart rests between beats. For example, a reading of 120/80 mmHg means a systolic of 120 and a diastolic of 80.
How accurate is this blood pressure risk calculator?
This calculator uses the American Heart Association (AHA) and American College of Cardiology (ACC) 2017 guidelines for blood pressure classification. It provides a general risk assessment and is not a substitute for professional medical evaluation. Always consult your doctor for personalized advice.
How often should I measure my blood pressure?
The AHA recommends checking blood pressure at least once a year if normal, or more frequently if elevated. For those with hypertension, home monitoring 2–3 times daily is often recommended. Use our Resting Heart Rate Fitness Score tool alongside BP monitoring for a fuller cardiovascular picture.
What is a hypertensive crisis?
A hypertensive crisis is a blood pressure reading above 180/120 mmHg. It requires immediate medical attention, especially if accompanied by symptoms like severe headache, chest pain, vision changes, difficulty breathing, or numbness. Call emergency services immediately if symptomatic.
Can lifestyle changes really lower blood pressure?
Yes. The DASH diet, regular exercise, weight management, sodium reduction, and stress management can each lower systolic BP by 4–11 mmHg. Combined, these changes can be as effective as medication for some people. Use our Sugar Intake Calculator and Water Intake Calculator to support healthier habits.
