What is a biological age calculator?

A biological age calculator estimates whether your body appears to be aging faster or slower than your calendar age. This tool uses your 31-question longevity assessment, five health dimensions, and total score to estimate biological age for educational purposes.

Is this free longevity test actually free?

Yes. The longevity test is free, takes about 10 minutes, and does not require an account. You receive a 0-100 score, a biological age estimate, a five-dimension radar chart, and a prioritized action plan.

What does a healthspan calculator measure?

A healthspan calculator focuses on the years you are likely to live with good energy, mobility, cognition, and independence. This assessment emphasizes healthspan rather than only total lifespan.

How is biological age calculated?

Your biological age is estimated by comparing your total longevity score against your actual age. A higher score suggests your body is aging slower than your calendar age, while a lower score may indicate faster biological aging.

What science is this based on?

Every question and recommendation is grounded in peer-reviewed research from journals like NEJM, The Lancet, Science, JAMA, and BMJ, covering 20+ million participants.

Is this a medical diagnosis?

No. This is an educational self-assessment tool. It is not a substitute for professional medical advice, diagnosis, or treatment. Always consult your doctor for medical decisions.

Yes. We collect zero personal assessment data. All calculations happen locally in your browser. Nothing from your answers is sent to any server.
