About the Life Expectancy Calculator
A period life table summarises the death rates of everyone in a population in one year. Life expectancy at a given age is how many more years, on average, someone of that age would live if those death rates stayed the same.
Expected age rises as you get older: surviving to 60 means you've already passed the risks of earlier years. Smoking, health conditions, income and country all change individual outlook; studies estimate lifelong smoking cuts about 10 years.
The formula
Expected age = current age + remaining life expectancy (from the life table)
Remaining years at selected ages (US, 2023)
| Age | Men | Women |
|---|---|---|
| 0 | 75.8 | 81.1 |
| 20 | 56.7 | 61.7 |
| 30 | 47.5 | 52.1 |
| 40 | 38.6 | 42.6 |
| 50 | 29.9 | 33.5 |
| 60 | 21.8 | 24.7 |
| 65 | 18.1 | 20.7 |
| 70 | 14.7 | 16.8 |
| 80 | 8.5 | 9.8 |
| 90 | 4.1 | 4.8 |
Worked example
Example: Expected age at death (on average) = 79.1
- Inputs: Sex: Male; Age: 44 years.
- Formula: Expected age = current age + remaining life expectancy (from the life table)
- Result: Expected age at death (on average) = 79.1
- Average remaining years: 35.08
- Life expectancy at birth (same table): 75.79
Things to keep in mind
- Uses United States population data; other countries differ.
- An average for a whole population, not a prediction for any one person.
Questions people ask
Why doesn't it account for my lifestyle?
Reliable official data only exist by age and sex; we don't add guessed adjustments.
What's a period life table?
It uses one year's death rates, so it doesn't include future medical progress.
