Life expectancy calculator: your years ahead
Choose an age, sex and country to see what published WHO life tables say about the years ahead for people in that group — expected remaining years, and the chance of reaching later ages. These are population statistics, not a prediction of how long you personally will live.
Your years ahead
40.7further years, on average
United States of Americaall peopleWHO age band 40–44
This is the expected further years for all people in the 40–44 age band in United States of America, from the published WHO life table. It describes a population, not you.
- Selected age
- 40 years · band 40–44
- Expected attained age
- 80.7 years
- WHO reference year
- 2023
Expected attained age is the band start (40) plus published remaining years, not your selected age plus an invented single-year estimate. It is a group average, not a predicted age at death for you.
Survival from here
The share of people in this population still alive at each later age band, starting from 100% at your current band.

WHO's abridged life tables end at the 85+ band, so survival to 90 or 100 cannot be derived from this source and is not shown.
How does this compare?
At the start of the 40–44 band, earlier deaths are excluded from the group. Expected total age can therefore sit above life expectancy at birth for the same population. Healthy years at birth measure a different endpoint, not healthy years remaining at your age.

How to read this result
A population statistic
The average experience of everyone of this age, sex and country under one year's death rates. Remaining life expectancy is the expected further years for people who have already reached this age band, and each survival probability is a ratio of two published survivor counts.
An individual prediction
Your own health, circumstances and future medical progress are not in the calculation. Nothing here estimates when a particular person will die, and it is not designed to.
Observed deaths
Recorded death rates by age group and sex.
Life table
Rates converted into survivors and person-years.
Published figures
Expected remaining years and survivor counts.

Source, data year and method
WHO Global Health Observatory — life tables by country · 2023 data · abridged life tables, five-year bands to 85+ · retrieved 2026-10-21
WHO abridged life tables. Ages are grouped in five-year bands up to 85+, so a selected age is mapped to its official band. Survival to a milestone age is the ratio of official lx values and is not interpolated.

What this calculator does
What it calculates
Remaining life expectancy for people of your age band, sex and country, and the share of them who would reach later ages such as 70, 80 and 85.
What data it uses
WHO Global Health Observatory — life tables by country, data year 2023. The published values are shown unchanged; survival is a ratio of published survivor counts.
What it is not
A personal lifespan prediction. It describes a population under one year's death rates, and knows nothing about your health, habits or future medicine.
Questions about the calculator
How accurate is this life expectancy calculator?
The figures are exactly those WHO publishes for the selected group and release. They cannot be accurate for one person: they are averages for everyone of that age band, sex and country, under the selected reference year's death rates.
Why does my expected age go up as I get older?
Because surviving to an age removes the chance of having died before it. Remaining years fall with age, but age plus remaining years rises. Why life expectancy changes with age.
Why is my age shown as a five-year band?
WHO publishes abridged life tables in five-year age groups, ending at 85 and over. The calculator uses the official band rather than inventing single-year values.
Why can't I see the chance of reaching 90 or 100?
The published table stops at 85+, with no survivor count at 90 or 100, so those probabilities cannot be calculated from this source without estimating them.
What is the life expectancy at 65?
It differs widely by country and sex. Set the age to 65 above, or read the country comparison Life expectancy at 65.
Does this include my health or lifestyle?
No. No personal information is used, and none is stored. For what the evidence says about individual factors, see What influences longevity.
