What this number means

Life expectancy is a population average. This calculator uses the Social Security Administration's 2023 period life table to estimate how many years remain at each age, then converts that figure into weeks. The Average option combines the male and female table values. Ages between published rows are estimated through interpolation.

Your result doesn’t account for your health, family history, income, location, medical care, habits, or random events. It can’t predict how long you’ll live. Use it to start the conversations or planning you’ve been putting off.

The short answer

Take your age, look up the years the Social Security Administration's 2023 period life table gives someone that age, and count both in weeks. A 40-year-old has lived about 2,087 weeks. The table gives a man that age about 2,014 more and a woman about 2,225. It's a population average, so it can't tell you how long you'll live.
