Life Expectancy Calculator

U.S. only tools

A life expectancy is one number doing two jobs. It is the average further years a person of your age is expected to live, and it is the wrong number to plan a retirement pot around — because half of the people your age live past it, and a quarter live about a decade past it. This page prints all three: the average, the median, and the age one in four reaches.

https://danfio.com/tools/life-expectancy-calculator/ - printed from this page

The average years remaining is measured from an exact age, so this is the person planning rather than the year they were born.

SSA publishes its table split this way and no other. Nothing on this page is a statement about a person.

The answer is the share of people of your age who reach it, read off the survivors column.

The years left fall more slowly than the age rises, because everyone who reaches 65 is no longer part of the group that died before it. That is why life expectancy at birth understates what an adult should plan for.

What this is: a period life table for the Social Security area population, built from one year of mortality experience (2023) and published with the 2026 Trustees Report. It is the arithmetic SSA uses for its own programs. What it is not: a prediction about you. It cannot see your health, whether you smoke, what you do for a living, your income or your family, and individuals differ from any average far more than the average differs from year to year. Half of the people alive at 45 reach 81 or beyond, and a quarter reach 88 or beyond, which is the spread the single number hides. It is a mortality statistic, not medical advice, and it says nothing about what any individual should do.
How planners use a table like this: not the average, but a tail. A retirement pot that only lasts as long as the average person lives has a coin-flip chance of running out in the retiree's lifetime, which is why the one-in-four age is the horizon usually tested - and why the same mortality table is what makes delaying a Social Security claim a good deal for someone in average health, since the credits for waiting are computed from life expectancy rather than from the age at which the payments start. Between the two, the honest reading of this page is: plan to a tail, and revisit it every few years.

The numbers come from the Social Security Administration’s period life table, the same table SSA uses to price its own programs. It is split by sex and by nothing else, because that is how SSA publishes it — so the page is careful about what it is: a population’s mortality, not a forecast about you.

About this life expectancy calculator

However long any one life runs, the average printed here is a population figure rather than a forecast for one person. The life expectancy calculator reads the Social Security Administration’s period life table — the 2023 table published with the 2026 Trustees Report — and prints the average further years, the age half of the group reaches, and the chance of any later age, all from the table’s own survivors column.

Every figure on the page is read off that survivors column and printed in full, so a mistyped life expectancy is caught before it reaches a visitor. The site sells no data and takes no advertising that depends on your age; nothing you type is stored or uploaded.

A life expectancy is a population statistic, not a quote about any individual. Nothing here is a medical, actuarial or financial opinion, and decisions about insurance or retirement money should be made on figures an actuary or a licensed professional would stand behind. Not investment or insurance advice; quotes come from a licensed provider.

How this life expectancy calculator works

What a period life table is

A period life table takes one year of mortality experience and asks a hypothetical question: if everyone alive today faced those same death rates at every age, how long would they live? The table on this page uses the SSA area population’s 2023 experience, as published with the 2026 Trustees Report, and it lists two columns per sex — the number of survivors out of 100,000 born alive at each exact age, and the average number of further years expected at that age.

Two consequences follow from the definition. It is a snapshot rather than a forecast: it does not assume medicine improves, and it does not assume it gets worse. And it is measured at an exact age rather than from birth, which is why life expectancy at birth — 75.79 years for men and 81.06 for women in this table — is lower than the age a 45-year-old can expect to reach.

Why the median is higher than the average

Deaths are not spread evenly: most people die in old age, but some die young, and those early deaths pull the average down while leaving the median where the middle of the group is. In this table a 45-year-old man has an average of 34.21 years left — an expected age of about 79 — while half of 45-year-old men reach 81 and a quarter reach 88. The gap between 79 and 88 is the part of the answer that matters for money, because a pot has to survive the tail, not the middle.

The table also shows the same effect inside itself: the older you get, the longer you are expected to live, because the people who would have died young are no longer in the group. A man of 65 has 18.12 years left, an expected age of about 83; a man of 85 has 6.04, an expected age of about 91.

What the table cannot know

It cannot see your health, whether you smoke, your weight, what you do for a living, your income, your family history or your access to care. Smokers and people with serious illnesses have materially shorter lives than the average in this table, and people with favorable health and means often live longer. Life insurers and annuity providers use tables that adjust for some of this, and they price accordingly — that is their business rather than this page’s.

So the honest use of a page like this is relative rather than personal: it tells you the shape of longevity risk, that it is skewed to the right, and that planning to the average is planning to a coin flip. It is a mortality statistic, not medical advice, and it does not know anything about you that you did not type in.

How every answer is read, and how to read it back

The table behind this page carries survivors out of 100,000 at each exact age, and every answer on the page is read from that column rather than guessed. The expectation is the average of the further years predicted for the whole group at the starting age. The median is the age at which half of the starting group are still alive, which is nearly always a year or two past the expectation. The one-in-four age is where a quarter remain, and the chance of any target age you name is simply how many of the 100,000 are still alive there, divided by 100,000.

That is why the page can answer an exact question — what is the chance a 45-year-old man sees 85 — and why the answer stays honest: it is a survivor ratio from a published table, not an opinion. Because the figure is a snapshot of one year of mortality, the same read works for any age and target age you type in, and the shape repeats itself: the further the target sits from the starting age, the longer the tail, and the larger the starting age, the larger every remaining chance becomes.

Worked examples

Each example below was run through the calculator on this page when the site was built, so the numbers match what you see when you enter the same inputs.

A man of 45

Your age now: 45 years · Sex: Male · Age to check the chance of reaching: 85 years

Expected age at death, from the table

79.2 years

That is 34.2 more years for a 45-year-old man, from the SSA 2023 period life table as used in the 2026 Trustees Report.

Years left on average: 34.2 · Half of people reach: 81 · One in four reach: 88 · Chance of reaching 85: 38.2%

34.21 years on average, an expected age of about 79 — but half of men this age reach 81 and a quarter reach 88, and the chance of reaching 85 is about 38 percent.

A woman of 65

Your age now: 65 years · Sex: Female · Age to check the chance of reaching: 90 years

Expected age at death, from the table

85.7 years

That is 20.7 more years for a 65-year-old woman, from the SSA 2023 period life table as used in the 2026 Trustees Report.

Years left on average: 20.7 · Half of people reach: 86 · One in four reach: 92 · Chance of reaching 90: 34.9%

20.66 years on average, an expected age of about 86, and a better than one-in-three chance of reaching 90 — the group that has already reached 65 is not the group the birth-time figures describe.

The long tail: a man of 45 asking about 95

Your age now: 45 years · Sex: Male · Age to check the chance of reaching: 95 years

Expected age at death, from the table

79.2 years

That is 34.2 more years for a 45-year-old man, from the SSA 2023 period life table as used in the 2026 Trustees Report.

Years left on average: 34.2 · Half of people reach: 81 · One in four reach: 88 · Chance of reaching 95: 6.8%

About a 7 percent chance — roughly one in fifteen. Small, and not small enough to ignore when the question is whether the money lasts.

A man of 85, asking about 95

Your age now: 85 years · Sex: Male · Age to check the chance of reaching: 95 years

Expected age at death, from the table

91 years

That is 6 more years for a 85-year-old man, from the SSA 2023 period life table as used in the 2026 Trustees Report.

Years left on average: 6 · Half of people reach: 90 · One in four reach: 93 · Chance of reaching 95: 17.8%

At 85 the average further years are 6.04, an expected age of about 91. The people who have already reached 85 are the long-lived group, so the median, the one-in-four and the chance of 95 all sit higher than the same questions would have sat at birth.

Frequently asked questions

How long will I live?

Nobody can answer that, and this page does not try to. What it can say is what the SSA period life table says about a person of your age and sex: the average further years, the age half of that group reaches, and the age a quarter reaches. Treat those as the range you are planning inside rather than as a date. The table’s own answer to the question people actually mean — will I be alive at 90 — is a probability, and that is on the page too.

Why is the median age higher than the average?

Because deaths are skewed towards old age: early deaths pull the average down without moving the middle of the group. In this table a 45-year-old man averages 34.21 more years, an expected age of about 79, while half of the men that age reach 81 and a quarter reach 88. For anything that has to last as long as you do — a retirement pot, a life annuity — the tail is the number to plan against, not the average.

Why does the table separate men and women?

Because SSA publishes it that way, and the difference is real: life expectancy at birth in this table is 75.79 years for men and 81.06 for women, about five years apart, and women have the longer expectancy at every age. The gap narrows as people get older but does not close. The page uses SSA’s own two columns rather than inventing an adjustment, so a visitor reads the table’s answer rather than a blended guess.

Does this account for my health, my smoking or my family history?

No, and no period life table can. Smoking, weight, long-term conditions, occupation and income all move mortality in ways this table does not see, and life insurers and annuity providers use tables that adjust for some of them — which is exactly why an annuity quote for a smoker differs from one for a non-smoker. What the page does is show where the population sits, so you can judge which way you are likely to be off it.

What does "period life table" mean?

It means the table is built from mortality during a short period — one year, in SSA’s case — and used to compute what a hypothetical population would experience if those rates applied at every age for the rest of their lives. It is a snapshot of today’s mortality rather than a forecast of medical progress, and SSA republishes it each year with the Trustees Report, which is why the table on this page carries its year and the report it was published with.

How should I use this for retirement planning?

Plan to a tail, and revisit it. Testing whether a pot lasts to the age one in four people of your age reach is a common standard, precisely because planning to the average would give the plan a coin-flip chance of failure. The same reasoning runs through the other calculators on this site: the retirement calculator asks how long the money has to last, and the Social Security calculator shows what waiting to claim does to a benefit that is paid for life.

Is this medical advice?

No. It is arithmetic on a published mortality table, and a mortality table describes populations rather than patients. Nothing here diagnoses anything, predicts anything about an individual, or should replace a conversation with a doctor about your own health. If you are making a medical decision this is the wrong tool; if you are working out how long a pot of money has to last, it is the right one.

What happens to the age and health answers I give on this page?

They stay on your device. Your age, your sex and the age you asked about are turned into a life-expectancy figure by arithmetic in the browser, and no copy is posted to a server or kept anywhere - there is no account and no upload endpoint to receive it. If a calculator page on this site ever made a network call, an automated release check would block it, which is what makes the privacy line enforceable rather than decorative.

Assumptions and sources

  • SSA Actuarial Life Table — the 2023 period life table for the Social Security area population, as used in the 2026 Trustees Report. For each exact age from 0 to 119 it gives the probability of dying within the year, the number of survivors out of 100,000 born alive, and the life expectancy. Both printed columns are carried here: the survivors column for every survival statement on the page, and the life expectancy column for the expectancy itself.
  • SSA Actuarial Life Table, definition — the period life expectancy at a given age is the average remaining number of years expected before death for a person at that exact age, born on 1 January, using the mortality rates of the period over the course of their remaining life.
  • SSA Actuarial Life Table, figures quoted on this page — life expectancy at birth is 75.79 years for males and 81.06 for females; at exact age 45 it is 34.21 and 38.01; at exact age 65, 18.12 and 20.66; at exact age 85, 6.04 and 7.02. The median, the one-in-four and the one-in-ten ages are read from the survivors column rather than interpolated from the life expectancy column.
  • SSA Actuarial Life Table, population — SSA describes the Social Security area population as residents of the 50 states and the District of Columbia (adjusted for net census undercount), civilian residents of Puerto Rico and the island areas, federal civilian employees, members of the armed forces abroad and their dependents, and other U.S. citizens abroad.
  • The table is republished annually with the Trustees Report, and every printed life expectancy is recomputed from the survivors column, so a mistyped figure is caught before it reaches a visitor.
  • Not modelled here: individual health, smoking, weight, occupation, income, family history and access to care; medical advances or declines; any adjustment for them; and any prediction about a specific person.
