Life Expectancy Estimate
How this calculator works:
It starts with the average life expectancy for your sex and adjusts based on well-documented lifestyle factors from medical research.
Base life expectancy (developed countries, 2024):
- Male: 76 years
- Female: 81 years
Factors that affect lifespan:
| Factor | Impact |
|---|---|
| Regular exercise | +3 to +7 years |
| Healthy BMI | +2 to +4 years |
| Non-smoker | +10 years vs smoker |
| Moderate alcohol | +1 to +2 years |
| Strong social connections | +3 to +5 years |
| Healthy diet | +2 to +4 years |
| Regular sleep (7-8 hrs) | +2 to +3 years |
| Low stress | +2 to +3 years |
Important: This is a statistical estimate based on population-level data. Individual results vary enormously. This is NOT a medical prediction — it is a motivational tool to show how lifestyle choices matter.
