Estimate your life expectancy based on lifestyle and health factors.
The Life Expectancy Calculator provides an educational estimate of your expected lifespan based on your current age, gender, and key lifestyle factors. While no calculator can predict the future, this tool illustrates how health choices impact longevity.
Life expectancy is influenced by many factors including genetics, lifestyle, healthcare access, and environmental conditions. Research consistently shows that certain modifiable behaviors—smoking, exercise, diet, and stress management—can significantly impact how long and how well we live.

Starts with actuarial tables (US average 76.4 years), then adjusts for lifestyle factors: smoking (-10 years), exercise (+3-5 years), healthy BMI (+2-3 years), diet, and social connections.
Smoking has the biggest negative impact (-10-15 years). Exercise, healthy weight, not drinking excessively, and strong social ties each add 2-5 years. Genetics account for ~25%.
Quit smoking, exercise 150+ minutes/week, maintain healthy BMI (18.5-25), eat more plants, limit alcohol, manage stress, get regular checkups, and nurture relationships.
