Estimate life expectancy based on age, gender, health conditions, and lifestyle factors. Useful for healthcare planning, screening decisions, and goals of care discussions.
This calculator provides population-based estimates only. Individual outcomes vary widely. Life expectancy estimates should be used as general guidance for healthcare planning, not as definitive predictions. Always consult with healthcare providers for personalized medical advice.
Enter valid age to calculate life expectancy
Life expectancy calculations are based on population-level data and actuarial tables adjusted for known risk factors. These estimates help inform healthcare decisions but cannot predict individual outcomes with certainty.
Women typically live 5-7 years longer than men. Life expectancy decreases with advancing age but the rate of decline varies.
Current smoking reduces life expectancy by 7-10 years. Former smokers who quit >5 years ago have partially reversed risk (-3 years).
Type 2 diabetes reduces life expectancy by 3-7 years depending on control and complications. Earlier onset has greater impact.
Cardiovascular disease reduces life expectancy by 2-5 years depending on severity and treatment.
Impact varies greatly by cancer type and stage. Average reduction is 3-5 years for common cancers with treatment.
BMI >30 reduces life expectancy by 2-5 years. Severe obesity (BMI >40) has greater impact (6-10 years).
Frailty syndrome significantly reduces life expectancy (5-7 years) and increases risk of adverse outcomes.
Life expectancy calculators provide population-level estimates with substantial individual variation. They are reasonably accurate for groups of people but cannot predict when any specific person will die. Estimates are most useful as general guidance for healthcare planning rather than precise predictions.
Life expectancy should be considered for: cancer screening decisions (most guidelines recommend considering 10-year life expectancy), preventive medication decisions (statins, aspirin), intensity of diabetes or blood pressure control in elderly patients, advance care planning discussions, and major surgical decisions in elderly or frail patients.
Yes! Many factors are modifiable. Quitting smoking can add 7-10 years. Maintaining healthy weight, regular exercise, controlling blood pressure and cholesterol, managing chronic diseases, staying socially connected, and avoiding excessive alcohol all improve life expectancy. Even modest improvements in health behaviors have meaningful impacts.
Life expectancy refers to total years of life, while healthspan refers to years lived in good health without significant disease or disability. A key goal is not just living longer, but maintaining quality of life and functional independence. Some interventions may extend life without improving healthspan.
Doctors use life expectancy estimates to: balance benefits and risks of treatments, guide cancer screening recommendations (typically if life expectancy <10 years, many screenings are not recommended), discuss goals of care with seriously ill patients, determine appropriateness of preventive medications, and help patients make informed decisions aligned with their values and preferences.
This requires clinical judgment and sensitivity. Frame life expectancy discussions as estimates with uncertainty, focus on implications for care decisions rather than specific numbers, assess patient readiness and desire for this information, emphasize that estimates guide planning not predictions, and always discuss within the context of patient goals and values.
This simplified calculator does not account for: race/ethnicity, socioeconomic status, education level, social support, access to healthcare, mental health conditions, kidney disease, COPD/lung disease, liver disease, specific cancer types/stages, disease severity or control, family history, exercise habits, diet quality, alcohol use, and many other factors that influence longevity.
Yes, more comprehensive tools exist including: the ePrognosis calculator for elderly patients, the Lee Schonberg index for 10-year mortality, the Walter index for various conditions, cancer-specific prognostic calculators, and the Social Security Administration life tables. These tools incorporate more variables and are disease-specific for improved accuracy.
