Definition of Life Expectancy
Life expectancy is a statistical estimate that predicts the average number of years a person is expected to live based on various demographic factors, established through the rigorous analysis of historical data and actuarial science. 📊 This information is crucial in financial contexts like life insurance pricing, pension planning, and social security benefits. Basically, if you want your actuary to smile, you better hope for a good life expectancy! 😄
Comparison: Life Expectancy vs. Life Span
| Aspect | Life Expectancy | Life Span |
|---|---|---|
| Definition | Average number of years a person is expected to live | Maximum number of years a person has lived |
| Measurement | Statistical estimate based on population data | Individual maximum attained age |
| Use in Finance | Guides life insurance and annuities pricing | Less relevant; mainly a historical measure |
| Variability | Can differ between demographics (age, gender) | Fixed once achieved |
Examples of Life Expectancy Use
-
Life Insurance: If you buy life insurance at 25, your premiums will typically be lower because the insurer believes you’re more likely to cash in your policy at a ripe old age of 120, rather than at 35 (oops!). 🪦
-
Pension Planning: Simply knowing your life expectancy can help you avoid the humiliation of outliving your savings—cashing in your pension each month like it’s a value menu!
