Life Expectancy Calculator

Estimate your life expectancy based on lifestyle

이 도구에 대해

Get a statistical estimate of your life expectancy by entering your age, sex, country, and a handful of lifestyle factors—smoking status, exercise frequency, BMI range, and diet quality. The calculator adjusts the WHO/UN baseline life-expectancy figures for your country based on well-studied risk modifiers and shows you years remaining, the percentage of life already lived, and a breakdown of how each habit affects your estimate. This is a statistical model, not medical advice.
