Life Expectancy (Insurance)
The statistical average number of years a person is expected to live, used by insurance companies to calculate premiums and benefits. This actuarial calculation considers factors like age, gender, health status, and lifestyle habits to assess mortality risk.
Example
“The insurance company used actuarial tables showing a 45-year-old non-smoking female has a life expectancy of 81 years when calculating her life insurance premium.”
Memory Tip
Life Expectancy = Life's Expected Length - insurers use this to EXPECT how long you'll live and price accordingly.
Why It Matters
Life expectancy directly impacts the cost and availability of life insurance, annuities, and long-term care coverage. Understanding your personal life expectancy helps in retirement planning and determining appropriate insurance coverage amounts.
Common Misconception
People often think life expectancy is a prediction of exactly when they'll die, but it's actually an average across large populations. Individual results vary dramatically - roughly half of people will live longer than their life expectancy, and half will live shorter.
In Practice
Sarah, a healthy 35-year-old non-smoker, has a life expectancy of about 83 years according to actuarial tables. Her life insurance company uses this 48-year expected lifespan to calculate that a $500,000 term policy should cost approximately $35 monthly. If she smoked, her life expectancy might drop to 76 years, increasing her premium to around $85 monthly due to higher mortality risk.
Etymology
Combines 'life' with 'expectancy' from Latin 'expectare' meaning 'to look out for' or 'await.' Modern life expectancy tables were developed by 17th-century mathematician Edmond Halley for early life insurance calculations.
