Life Expectancy Calculator
A rough estimate of how long you'll live, based on CDC life tables and a few lifestyle factors. It can't see the future, but it can see your habits.
- Estimated life expectancy
- Years remaining
- Which habits matter most
Life expectancy in the United States
According to the CDC, U.S. life expectancy at birth was 78.4 years in 2023: 75.8 for men and 81.1 for women. People who've already reached middle age have a higher expected age, because they've survived the earlier risks.
What changes life expectancy most?
- Smoking, which research links to about 10 years of lost life
- Regular exercise
- Heavy drinking
- Obesity
The estimate adjusts the CDC average for each factor. Genetics, income, location and healthcare all matter too.
Why it's sometimes called a death calculator
Because it estimates when you'll die, though "life expectancy calculator" sounds nicer. To see how much life you've already used, try the Age Calculator.
