How to Use This Calculator
This calculator estimates your life expectancy based on demographic data, body measurements, and lifestyle factors. Enter your age, gender, height, weight, and habits to receive a personalized estimate.
The calculation uses country-specific life expectancy data from the World Health Organization, adjusted by lifestyle factors based on epidemiological research.
Factors That Affect Life Expectancy
Body Mass Index (BMI)
Maintaining a healthy BMI (18.5-24.9) is associated with lower risk of chronic diseases. Both underweight and obesity can reduce life expectancy by several years.
Physical Exercise
Regular exercise can add 3-7 years to your life. Even moderate physical activity, like 30 minutes of daily walking, significantly reduces all-cause mortality.
Diet Quality
A balanced diet rich in fruits, vegetables, whole grains, and lean protein can add 2-4 years to your life. Mediterranean and plant-based diets show the greatest benefits.
Smoking
Smoking is the most significant avoidable lifestyle factor. Smokers lose an average of 10 years of life expectancy. Quitting smoking at any age provides substantial health benefits.
Alcohol Consumption
Heavy alcohol consumption can reduce life expectancy by 5+ years. Moderate consumption (1 drink/day for women, 2 for men) has neutral to slightly protective effects for heart disease.
Understanding the Results
Mortality Probability
This chart shows your cumulative probability of death at different ages. It is calculated using actuarial life tables adjusted by your personal lifestyle factors.
Top Causes of Death
The personalized causes of death are based on your country's mortality statistics, adjusted by your risk factors. For example, smokers see higher probability of lung cancer and heart disease.
Lifestyle Impact
The impact breakdown shows how each lifestyle factor affects your life expectancy. Positive numbers indicate years added; negative numbers indicate years lost compared to the population average.

Frequently Asked Questions
How accurate is this calculation?
This calculator provides a statistical estimate based on population data and known lifestyle factors. Individual life expectancy varies due to genetics, healthcare access, environmental conditions, and other factors not captured here.
Why does my life expectancy differ from my country's average?
The national average includes people of all lifestyles and health conditions. Your personal lifestyle factors can add or subtract years from that average. For example, non-smokers with regular exercise typically exceed the national average.
Can I change my life expectancy?
Yes! While you cannot change your age or genetics, lifestyle factors account for a significant portion of life expectancy. Making positive changes at any age can improve both life expectancy and quality of life.
What data is used for this calculation?
We use life expectancy data from the World Health Organization for 15 countries, combined with lifestyle adjustments derived from large-scale epidemiological studies published in peer-reviewed medical journals.
