What Is the Life Expectancy Calculator?

This online calculator offers a personalized estimate of your life expectancy based on scientifically recognized lifestyle and demographic factors. Unlike basic age predictors, our tool takes into account eight essential variables:

  • Age
  • Gender
  • Smoking habits
  • Alcohol consumption
  • Exercise frequency
  • Diet quality
  • Sleep duration
  • Stress levels

These data points are processed through a customized algorithm, adjusting the base life expectancy accordingly to reflect realistic outcomes.

🧠 Behind the Scenes: How the Calculator Works

This tool begins with a base life expectancy of 80 years, which is then adjusted as follows:

  • Gender:
    • Female: +4 years
    • Other/Prefer not to say: +1 year
  • Lifestyle Adjustments:
    • Smoking: Up to -7 years
    • Alcohol: Up to -3 years
    • Exercise: Up to +3 years
    • Diet: Up to +2 years
    • Sleep: Up to +2 years
    • Stress: Up to +2 years

The final output is limited to a maximum of 120 years and at least one year beyond your current age.

💡 Practical Example

Let’s say a user inputs the following:

  • Age: 40
  • Gender: Female (+4)
  • Smoker: No (0)
  • Drinks: Moderately (0)
  • Exercise: 3+ times/week (+3)
  • Diet: Good (+2)
  • Sleep: 6–8 hours (+2)
  • Stress: Low (+2)

Calculation:

  • Base = 80
  • Gender = +4 → 84
  • Lifestyle = +9 → 93
  • Final Life Expectancy = 93 years

So, the tool estimates that this 40-year-old woman will likely live to be 93 years old, given her current habits.
