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:

  1. Current Age – Your starting point.
  2. Gender – Base life expectancy differs by gender (average 76 years for men, 81 for women).
  3. Lifestyle Factors – Includes smoking status, exercise, diet, stress, and BMI.
  4. 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.

Step 9: Click “Calculate”

The calculator outputs:

  • Gender: Female
  • Smoking: Never smoked
  • Exercise: 3–4 times/week
  • Diet: Good
  • Family History: 76–85
  • Stress: Moderate
  • BMI: Normal

Calculation:

  1. Base life expectancy: 81
  2. Lifestyle adjustment: 0 + 4 + 3 + 3 + 0 + 4 = +14
  3. Estimated Life Expectancy: 81 + 14 = 95
  4. Years Remaining: 95 − 40 = 55
  5. Health Rating: Excellent

Health Rating Guide

  • Excellent → +15 years or more
  • Good → +5 to +14 years
