Life Expectancy Calculator
Our Life Expectancy Calculator provides a personalized estimate of how long you may live based on statistical averages and lifestyle factors.
By entering your:
- Date of birth
- Gender
- Country/region
- Lifestyle habits
- Smoking status
- Exercise frequency
- Family history
- BMI category
You’ll receive an estimate of:
- Current age
- Estimated life expectancy
- Years remaining
- Approximate days remaining
- Estimated lifespan date
- Percentage of life lived
- Retirement outlook at age 65
This tool is designed for awareness, planning, and educational purposes — not medical prediction.
How the Life Expectancy Calculator Works
The calculator uses:
1. Base Country Life Expectancy
Each country has an average lifespan estimate (for example):
- United States: 79 years
- Canada: 84 years
- Japan: 84 years
- Global Average: 77 years
These averages serve as the starting baseline.
2. Gender Adjustment
Statistically, females live longer than males in most countries.
The calculator adds a modest adjustment for female life expectancy.
3. Lifestyle Adjustments
Additional years are added or subtracted based on:
- Healthy lifestyle habits
- Smoking status
- Exercise frequency
- Family longevity
- BMI category
Each factor slightly adjusts the base average.
