Free Biological Age Calculator
Estimate your biological age with a 10-minute, science-backed longevity assessment. Instead of asking for lab uploads, this calculator uses practical health and lifestyle inputs to show where your aging risk may be coming from.
What this biological age calculator checks
The assessment covers the five areas most people can measure and improve without a clinic visit.
- Metabolic baseline: BMI, waist circumference, heart rate, and blood pressure
- Lifestyle: diet quality, movement, strength, smoking, and alcohol
- Sleep: duration, regularity, quality, and evening routines
- Mind and social: stress, relationships, purpose, and cognitive engagement
- Prevention: checkups, family history, dental care, and early detection habits
What you get after the test
You receive a biological age estimate, a 0-100 longevity score, a five-dimension radar chart, and prioritized steps for today, this month, and ongoing improvement.
