Formula
Adjusted LE = Base LE ± Smoking ± Exercise ± BMI modifiersBase LE = Population average: 76 (male) / 81 (female) in the US
Smoking = -10 years for current smokers
Exercise = +0.5 to +4 years based on weekly frequency
BMI = -1 to -3 years for overweight/obese
Worked Example
35-year-old non-smoking male, BMI 24, exercises 3x/week
Did you know? Between 1900 and 2020, average global life expectancy more than doubled from ~31 years to ~73 years, primarily due to improvements in sanitation, antibiotics, and childhood vaccination (source: Our World in Data).
