How to read it
A life table average is useful. It is not a personal forecast.
The calculator uses remaining-life values from the Social Security Administration actuarial life table. Those values describe a population average for a person who has already reached a given age.
Your real life can be shorter or longer than the table average. Health, family history, habits, medical access, chance, and future conditions are not included. Use the estimate for perspective and planning, not certainty.
