Estimate Life Expectancy
Life Expectancy: Understanding Your Potential Lifespan
Life expectancy represents the average number of years a person can expect to live based on current mortality rates. Our calculator provides an estimate based on your demographics and lifestyle factors, helping you plan for retirement, insurance, and long-term goals.
Global Life Expectancy Statistics
Life expectancy varies dramatically around the world:
- Global Average: Approximately 73 years (2023)
- Highest: Japan and Switzerland at 84+ years
- Lowest: Central African Republic at around 53 years
- Historical Growth: Doubled from 35 years in 1900 to 73 today
- Gender Gap: Women live 4-5 years longer globally
Remarkable Progress
Life expectancy has increased more in the last 150 years than in the previous 100,000 years combined. This is due to advances in medicine, sanitation, nutrition, and reduced infant mortality.
