Reviewed by Calculator Editorial Team
This life expectancy calculator estimates your remaining years based on health factors. While not a medical diagnosis, it provides general guidance by comparing your health profile to national averages. The calculator considers factors like smoking status, exercise habits, diet, and chronic conditions.
How This Calculator Works
The life expectancy calculator uses a combination of health factors to estimate your remaining years. The formula accounts for:
- Current age
- Gender
- Smoking status
- Exercise frequency
- Diet quality
- Presence of chronic conditions
- Family history of early deaths
Formula: Estimated life expectancy = Base expectancy + (Age factor × Current age) + (Health score × 10)
Where Health score is calculated from your responses to health questions.
The base expectancy is derived from national averages, and the health score adjusts this estimate based on your answers.
Key Health Factors
Several health factors significantly impact life expectancy. The calculator considers these in its estimation:
| Factor | Impact |
|---|---|
| Smoking status | Reduces life expectancy by 5-10 years |
| Exercise frequency | Increases life expectancy by 2-5 years |
| Diet quality | Increases life expectancy by 1-3 years |
| Chronic conditions | Reduces life expectancy by 5-15 years |
These factors are weighted differently in the calculation based on their relative impact on longevity.
