Life Expectancy Calculator
Estimate life expectancy based on age, lifestyle, and health factors.
About this Calculator
Life expectancy estimates are based on statistical averages from insurance and public health data, adjusted by known risk and protective factors. This calculator starts with your baseline life expectancy by age and sex, then adds or subtracts years based on factors like smoking status, BMI, exercise habits, diet quality, stress level, and family history. The result is an estimate — not a prediction — that highlights which lifestyle changes have the most impact.
