Mortality Calculator

Understanding your life expectancy isn’t just about curiosity—it’s about planning. Whether you’re considering retirement, adjusting your lifestyle, or simply want to assess your health risks, our Life Expectancy Calculator is a simple and insightful tool to help you make informed decisions.

By analyzing key health indicators—age, gender, smoking status, activity level, and BMI—this tool gives you an estimate of how many years you may have left and your projected age at death. Backed by simplified public health data and common actuarial assumptions, this tool helps visualize how lifestyle choices impact longevity.

🔧 How to Use the Life Expectancy Calculator (Step-by-Step)

Using the calculator is fast and straightforward. Here’s how:

  1. Enter Your Current Age (Years):
    Input your age in whole years. Only numbers are allowed, and the minimum is 0.
  2. Select Your Gender:
    Choose either Male or Female. Statistically, women tend to live longer.
  3. Choose Smoking Status:
    Select Yes if you’re a smoker or No if you’re not. Smoking significantly reduces life expectancy.
  4. Pick Physical Activity Level:
    Choose your approximate activity level:
    • Low (sedentary)
    • Moderate (light exercise or active daily life)
    • High (frequent vigorous exercise)
  5. Enter Your BMI (Body Mass Index):
    Input your BMI, a measure of body fat based on height and weight. A healthy BMI typically ranges between 18.5–25.
  6. Click “Calculate”:
    The tool processes your information instantly and displays:
    • Remaining Years (how many years you may have left)
    • Estimated Age at Death
  7. Click “Reset” to clear the form and try again with different values.

This user’s lifestyle choices—non-smoker, moderate activity, healthy BMI—are contributing positively to their longevity.

💡 Why This Tool Matters

Life expectancy calculators offer a quick glance at your overall health and potential lifespan based on well-known risk factors. While it’s not a substitute for professional medical advice, it’s a valuable awareness tool for:

  • Financial Planning: Helps estimate retirement savings needs and Social Security timing.
  • Lifestyle Motivation: Encourages healthier habits by showing the impact of smoking, inactivity, or BMI on life expectancy.
  • Health Assessments: Supports conversations with doctors, dietitians, and fitness coaches.

🧠 Behind the Calculations

Our tool uses simplified actuarial rules to determine a base life expectancy—76 years for males and 81 for females—then adjusts based on:

  • Smoking: Subtracts 10 years.
  • Physical Activity:
    • Low: -3 years
    • Moderate: no change
    • High: +2 years
  • BMI:
    • Under 18.5 or over 30: -2 years
    • 22–25: +1 year

These modifications are based on statistical health data. The calculator then subtracts your current age to estimate how many years remain.

🏥 Common Use Cases

  • Insurance agents assessing client risk factors
  • Doctors and clinics educating patients about lifestyle risk
  • HR departments promoting wellness programs
  • Personal use for tracking lifestyle changes
  • Retirement planners factoring in longevity
