About Biological Age Test
We believe everyone deserves to understand how their lifestyle shapes their long-term health. Our free biological age calculator gives you instant insight — no sign-up, no data collection, just science-based answers.
Why We Built This
Our Mission
Healthspan data should not be locked behind expensive lab tests or paywalls. We built this tool to make biological age estimation accessible to anyone with an internet connection. By answering a few simple questions about your daily habits, you can get a personalized estimate of how your lifestyle is affecting your biological age — completely free and private.
Understand Your Body
What Is Biological Age?
Biological age is a measurement of your body's true physiological state and cellular health. Unlike chronological age, which only counts your birthdays, biological age reflects how well your cells and organs are functioning relative to scientific aging standards.
Chronological Age
Simply the number of years you have been alive. It is a linear, unavoidable measure of time passing.
Biological Age
Refers to your true physiological age. As established in longevity science, biomarkers of aging measure your body's functional capacity and cellular health, predicting healthspan much better than a calendar can.
Chronological vs. Biological Age
While your chronological age ticks forward at a fixed rate, your biological age is fluid — influenced by your daily habits, environment, and lifestyle choices. Two people of the same chronological age can have very different biological ages depending on their health profiles.
The Science Behind It
While advanced biogerontology relies on molecular tools like theepigenetic clock(DNA methylation) ortranscriptomic clocksto map your unique "ageotype," daily lifestyle choices are the primary drivers shifting these biological markers.
Our Method
How Our Calculator Works
Our algorithm evaluates your responses across multiple health dimensions and compares them against population-level data to estimate your biological age. Here is what we assess:
Personal Factors
Age, gender, family history, sleep habits, and education level.
Heart & Lifestyle
Blood pressure, cholesterol, smoking status, stress levels, and physical activity.
Medical Factors
Existing conditions, medication use, and preventive care habits.
Nutrition
Diet quality, fruit and vegetable intake, fat consumption, processed food intake, and alcohol use.
Psychological Factors
Happiness, anxiety, depression, social connections, and life satisfaction.
