How to Use the Life Expectancy Calculator (Step-by-Step)
Using the Life Expectancy Calculator is simple. Just follow these quick steps:

2. Enter Your Current Age
Input your current age. The calculator accepts values from 0 to 120.

Example: See How It Works in Real Time
Let’s say you’re a 40-year-old woman living in Japan. You do not smoke, exercise 4+ times per week, maintain a healthy diet, and drink alcohol moderately.
Here’s how the tool estimates her life expectancy:
- Base expectancy in Japan for females: 87 years
- Non-smoker: no deduction
- Active exercise: +2 years
- Healthy diet: +2 years
- Moderate alcohol: -1 year
Total Life Expectancy = 87 + 2 + 2 – 1 = 90 years
Years Remaining = 90 – 40 = 50 years
