Tools Life Expectancy Calculator
How many weeks and weekends do I have left?
Estimate your life expectancy from official U.S. life tables and see your life in weeks: the weeks, weekends and summers you have left.
Your result
One square per week, one row per year, from birth to the average age for your age and sex.
What to focus on next
Beyond the countdown
How many weeks you have matters less than how much of each one is yours.

How this calculator works
The numbers come from the Social Security Administration’s period life table for 2023, the table its actuaries use in the 2026 Trustees Report. For every age from 0 to 119 it gives the chance that a man or woman of that age dies within the year. Following 100,000 people through those odds gives how many reach each birthday, and the average number of years still ahead at your age.
Average age reached = your age + life expectancy at your age
Weeks left count 52.18 weeks a year (365.25 days ÷ 7), and every week has one weekend, so the two figures match. Summers left counts the whole years ahead. The grid uses 52 squares a row so each row is one year, an idea popularized by Tim Urban’s “Your Life in Weeks” chart.
A period table assumes today’s death rates stay fixed for the rest of your life. Death rates have usually fallen over time, so many people will live somewhat longer than this. These are population averages, not a personal prediction: health, habits, income and family history all shift real odds. For why seeing your time this way matters, read the Time Wealth guide.
Words you’ll see
- Life expectancy
- The average number of years people of a given age and sex have left, if today’s death rates hold.
- Period life table
- A table built from one year’s death rates at every age. It shows what would happen to a group who faced those rates for life.
- Median age at death
- The age half of people your age and sex live past. It is a little higher than the average, because a few early deaths pull the average down.
- Time wealth
- How much of your time is truly yours to spend on what matters to you.
Common questions
How is life expectancy calculated?
Actuaries start from how many people of each age and sex died in one year, then follow an imaginary group of 100,000 people through those death rates, one birthday at a time. Life expectancy at your age is the average number of years the people still alive at that age go on to live. This calculator uses the Social Security Administration’s period life table for 2023.
What is the average life expectancy in the U.S.?
At 2023 death rates, a baby boy in the U.S. can expect to live about 75.8 years and a baby girl about 81.1 years. The CDC’s National Center for Health Statistics puts life expectancy at birth for everyone combined at 78.4 years for 2023.
How many weeks are in an average lifetime?
About 4,000. At 2023 U.S. death rates, life expectancy at birth works out to about 3,955 weeks for males and 4,230 weeks for females, counting 52.18 weeks in an average year.
Why does my life expectancy go up as I get older?
Every year you live, you have already come through the risks that cut some lives short, so your expected age at death rises. A 65-year-old man can expect about 18.1 more years, to around 83, well past the 75.8 years expected at birth. A 65-year-old woman can expect about 20.7 more, to around 86.
Is this a prediction of when I will die?
No. These figures are averages for everyone in the U.S. of your age and sex, and they assume today’s death rates never change. Your own health, habits, income and family history can move your odds a long way in either direction, so treat the grid as a way to see your time, not a forecast.
