Life Expectancy Test
Your age, then a dozen questions. About 2 minutes, free, no email.
Average life expectancy
First, your age
40
Set your age and it carries over. Free, built on CDC life tables and our methodology. Nothing you set here leaves your browser.
The tiles show the average for women and for men at the age on the slider. The test starts there and moves it with each answer, so the number you finish on is yours.
What the test asks
Every screen is one question, and the first one is your age. Then the dozen below. Four of them take sliders, your sex takes one of three answers, and the rest take one of five.
- SexWhat was your sex at birth?
- BMIWhat’s your height and weight?
- SleepHow many hours do you sleep on a typical night?
- ExerciseHow many days a week are you physically active?
- AlcoholHow many alcoholic drinks do you have weekly?
- DietHow well do you eat?
- StressHow stressed do you feel most days?
- RelationshipsHow connected do you feel to others?
- SmokingHow often do you smoke or vape?
- PurposeDo you have a clear sense of purpose?
- Health ChecksDo you manage your health numbers?
- Family HistoryWhat age did your oldest grandparent reach?
No question asks for a diagnosis, a blood test or a blood pressure reading. The one about your health numbers asks whether you know and manage them, never the readings themselves.
What you get at the end
Every life expectancy test is asking one question. How long will I live? The answer here is an estimated lifespan, with the average for your age and sex beside it, and everything under it is free.
- Your estimated lifespan, and how it compares against the average for your age and sex, with the road ahead drawn on the same card.
- Your full report, free. Your biological age, every habit ranked with the years it is worth to you, the longevity archetype you fit, and a 90-day plan you can print.
- Something to send. Share your numbers or your life in months, or compare with someone you love and see how much time you have left together.
How the test is scored
The test is not a points quiz. Each answer moves an estimate that starts from the CDC's 2024 United States life table for your age and sex, with an allowance for mortality continuing to improve. Eleven factors move it, your weight, nine habits and your family history, each anchored to a named study, and the gains from good habits are discounted where they overlap, so they never simply add up. The same answers give the same number on the same engine version, and every change to the engine is dated in the model changelog. Every source is on the methodology page.
It has not yet been tested against recorded deaths in a large group followed for years, which is the only way to score a tool like this. What you can check is how it is built.
The averages the test starts from
The test starts from these numbers. They are the engine's averages for the United States. They run above the CDC's published figures because of the allowance for improving mortality, by between two and three years at 20, about two at 40 and under a year from 65 on, and your answers move yours from there.

| Average | Years left | Average | Years left | |
| 20 | 84.9 | 64.9 | 80.0 | 60.0 |
| 30 | 84.8 | 54.8 | 80.3 | 50.3 |
| 40 | 84.8 | 44.8 | 80.8 | 40.8 |
| 50 | 85.2 | 35.2 | 81.7 | 31.7 |
| 60 | 86.0 | 26.0 | 83.1 | 23.1 |
| 65 | 86.7 | 21.7 | 84.2 | 19.2 |
| 70 | 87.7 | 17.7 | 85.6 | 15.6 |
| 80 | 90.3 | 10.3 | 89.0 | 9.0 |
| 90 | 95.1 | 5.1 | 94.4 | 4.4 |
The average lifespan and the years left at each age, for the United States, from the Longlevity engine on the CDC’s 2024 life tables with the allowance for mortality continuing to improve. The test starts from the average for your age and sex and moves it with your answers.
A test, a quiz or a calculator?
The life expectancy calculator gives you a number on its page from your age, sex and a few optional answers, and you never leave the page. This page is the test itself. It asks the dozen questions one at a time and gives you the number at the end. Same engine, same averages, a different way in. If you want a number now, use the calculator. If you want to answer the questions, start here.
Frequently asked questions
Is this life expectancy test free?
Yes, all of it. The dozen questions, the estimated lifespan at the end and the full report under it cost nothing and ask for no email, no account and no card. The only time you are offered an email field is at the end, where you can send yourself a link to come back to or save your results, and both are optional.
How long does the life expectancy test take?
About 2 minutes. Your age, then a dozen questions, one per screen. You see your estimate the moment you finish.
What questions does the test ask?
Your age, your sex at birth, your height and weight, then ten questions about how you live, from sleep to how long your family has lived. The twelve are listed above, in the order the test asks them and in its own words.
Do I need an email or an account to take the test?
No. Nothing on this page or in the test asks for an email. At the end you can email yourself a link to your results if you want one, and you can save them to a free account to re-measure later, but both are optional.
How accurate is a life expectancy test?
No test can tell you the year you will die, and one that claims to is overselling. A tool like this can only be scored against recorded deaths in a large group followed for years. Some research tools have been tested that way. Ours has not yet been. What you can check is how it is built, and ours is built on the CDC's current life table, a named study behind every habit, a published method and a dated record of changes, all on the methodology page. Treat the number as a direction to move in, not a verdict.
Is this a life expectancy quiz?
It asks questions and ends on a number, so you can call it one. The difference from most online quizzes is the scoring. There are no points. Each answer moves an estimate built from the CDC's life tables and published mortality studies, and the method is public.
Is this a life expectancy survey?
No. A survey gathers answers from many people. This is a test of your own habits, scored for you, and the result is yours at the end. Your answers stay in your browser unless you choose to save them or email them to yourself, and we never sell or share them.
Can I take the test for a parent or a partner?
The test is about your own habits, so take it for yourself. For a parent, the time left with parents calculator gives the average years ahead at their age and how many visits that is at your pace. For a partner, finish the test and use the compare card at the end.
What is a good result?
The test gives an estimated lifespan, not a score, so there is no pass mark. The useful read is against the average for your age and sex, which the results show, and then which habits are helping and which are costing you years, which the report ranks. A result below the average is not a verdict. The report shows what would move it.
Does the test use my medical history?
No. Nothing in the twelve asks about a diagnosis, a prescription, bloodwork or a blood pressure reading. The one question near that ground asks whether you know and manage your health numbers, never the readings themselves. A condition a doctor is treating is outside what the test can see, so take the number to that conversation rather than in place of it.
Can I retake the test?
Yes, as often as you like, free. Habits change and so does the number. Save your results to a free account and in a year we invite you back to re-measure, so your history shows how the estimate moved.
Is the test based on the CDC's life tables?
Yes. The starting point is the CDC's United States life table for 2024, read for your age and sex, with an allowance for mortality continuing to improve, which puts the averages above the CDC's published figures, by about two years at 40 and under a year from 65 on. Your answers move the number from there. The detail is on the methodology page.
How is this different from the life expectancy calculator?
Same engine, same averages. The calculator gives a number on its own page from your age, sex and a few optional answers. The test asks all twelve questions one at a time and gives the number at the end, with the full report under it.
