1. What is Life Expectancy By Age?

Life expectancy by age refers to the average number of years a person of a given age is expected to live, based on current mortality rates. It changes as you age because you've already survived certain risks.

2. How Does the Calculator Work?

The calculator uses actuarial life tables:

Where:

• \( LE \) — Life expectancy (years)
• Table values are derived from national mortality statistics
• Values differ by country, gender, and current age

Explanation: The calculation uses period life tables which show what would happen to a hypothetical cohort if it experienced the current mortality rates at each age throughout its lifetime.

3. Importance of Life Expectancy Calculation

Details: Knowing life expectancy helps with retirement planning, health decisions, and understanding population health trends. It's used by insurers, pension funds, and healthcare providers.

4. Using the Calculator

Tips: Enter your current age in years, select your gender and country. The calculator will show average remaining life expectancy based on the most recent available data.

5. Frequently Asked Questions (FAQ)

Q1: How accurate are these estimates?
A: They're based on current mortality rates which may change. Your personal expectancy may differ based on health, lifestyle, and other factors.

Q2: Why does life expectancy increase as you age?
A: Because you've already survived higher-risk younger years, your remaining life expectancy can actually increase as you age.

Q3: How often is this data updated?
A: National statistics agencies typically update life tables annually or biennially.

Q4: What's the difference between period and cohort life expectancy?
A: Period life expectancy assumes current mortality rates continue, while cohort accounts for projected future improvements in mortality.

Q5: Does this account for personal health factors?
A: No, these are population averages. Personalized assessments would require health and lifestyle data.
