Biological Age Calculator | Calculate Your True Age
Calculate your biological age versus chronological age. See how your lifestyle impacts how fast your body is aging.
This is a lifestyle score, not a measured biological age
The result adds or subtracts illustrative amounts for sleep, exercise, diet, stress and smoking and expresses the total in years. Each direction matches the research — smoking, inactivity, short sleep and poor diet are all associated with higher mortality — but the specific year values are simplified, not taken from a validated model.
Validated biological-age measures, such as PhenoAge or DNA-methylation (epigenetic) clocks, require blood biomarkers or a lab test. Use this page as a prompt for which habits to look at, not as a clinical measurement.
Results are statistical estimates based on population-level research, not individualized medical advice. Consult a qualified healthcare professional before making health decisions.
