Life Expectancy Calculator
Answer a few quick lifestyle questions to see a simplified, informational biological age estimate.
About this calculator
This life expectancy calculator produces a lightweight, informational estimate of biological age by adjusting your chronological age based on commonly cited lifestyle factors — exercise frequency, sleep, diet quality, stress, and smoking status.
It is intentionally simple and meant for reflection and motivation, not diagnosis. Clinical biological-age tests (e.g. based on blood biomarkers or epigenetic markers) are the only scientifically validated way to estimate biological aging.
How it works
Enter your chronological age
This is your actual age in years.
Answer the lifestyle questions
Exercise frequency, sleep, diet quality, stress level, and smoking status.
Get your estimate
See an estimated biological age alongside the adjustment applied and what drove it.
Frequently asked questions
Is this a real biological age test?
No — real biological age testing uses lab measurements like bloodwork or epigenetic (DNA methylation) analysis. This tool offers a simplified, informational estimate based on self-reported lifestyle habits.
Can I improve my score?
The factors used here — more consistent sleep, regular exercise, lower stress, and not smoking — are all genuinely associated with healthier aging in research, so working on them is a reasonable goal even if this specific number is just illustrative.
Should I make health decisions based on this result?
No — treat it as a fun, motivational snapshot. Speak with a healthcare provider for any real health assessment or before making changes to exercise, diet, or medication.
