Life Expectancy (Insurance)
The statistical average number of years a person is expected to live based on demographic factors like age, gender, health status, and lifestyle. Insurance companies use life expectancy tables to calculate premiums and benefits for life insurance policies and annuities.
Example
“The insurance company used actuarial tables showing a 45-year-old male's life expectancy of 78 years to calculate his life insurance premium.”
Memory Tip
Life Expectancy = Life Expected - it's how long statisticians expect your life to last based on data from similar people.
Why It Matters
Life expectancy calculations directly impact insurance costs and retirement planning needs. Understanding your statistical life expectancy helps determine how much life insurance coverage you need and how long your retirement savings must last.
Common Misconception
People often think life expectancy is a prediction of when they'll die, but it's actually a statistical average for large groups. Individual circumstances like health, lifestyle, and genetics can significantly vary from population averages.
In Practice
Sarah, a healthy 35-year-old female non-smoker, has a life expectancy of about 84 years according to insurance tables. Her life insurance company uses this to calculate that she'll likely pay premiums for 49 years, influencing her $500,000 policy's monthly premium of $32. If Sarah were a smoker, her life expectancy would drop to about 79 years, and her premium would increase to approximately $85 monthly due to the higher mortality risk.
Etymology
The term combines 'life' and 'expectancy' from Latin 'expectare' meaning 'to look out for.' Actuarial life tables were first developed in the 17th century by mathematician John Graunt using London mortality data.
