My Life Expectancy Calculator
Knowing your potential life expectancy can help you make informed lifestyle choices. Our Life Expectancy Calculator estimates your lifespan, remaining years, lifestyle impact, and health rating in a simple, interactive way.
How the Calculator Works
The calculator combines multiple factors to provide a realistic estimate:
- Current Age – Your starting point.
- Gender – Base life expectancy differs by gender (average 76 years for men, 81 for women).
- Lifestyle Factors – Includes smoking status, exercise, diet, stress, and BMI.
- Family History – Longevity of parents influences your potential lifespan.
Each factor adds or subtracts years from a base life expectancy to show the adjusted estimate.
