Life Expectancy Calculator
What Is Life Expectancy?
Life expectancy is the average number of years a person is expected to live based on current age, sex, and mortality statistics. It is a key metric used in retirement planning, insurance underwriting, public health policy, and estate planning.
This calculator uses the U.S. Social Security Administration's Period Life Table, which represents the mortality experience of the entire U.S. population in a given year. It shows, for each age, the average remaining years of life expected.
Life expectancy has increased significantly over the past century due to advances in medicine, sanitation, nutrition, and public health. However, individual life expectancy varies based on genetics, lifestyle, health conditions, and access to healthcare.
