Biological Age Calculator
Estimate a lifestyle-based biological age proxy from BMI, smoking, activity, sleep, diet, stress, blood pressure and resting heart rate.
Lifestyle biological age proxy
Search results for biological age calculator often mix lifestyle quizzes, blood biomarker calculators and epigenetic clock products. This tool is intentionally framed as a lifestyle screening estimate, not an epigenetic clock and not a blood biomarker test.
Directional score from questionnaire factors.
What the questionnaire uses
| Input area | What it can signal | Important limitation |
|---|---|---|
| BMI | Weight-for-height screening | Does not measure body composition or fluid status. |
| Smoking and alcohol | Lifestyle risk signals | Dose, duration and medical history matter. |
| Activity, sleep and diet | Modifiable healthspan habits | Self-report is approximate. |
| Blood pressure and resting heart rate | Cardiovascular context | Repeated measurements and clinical context are required. |
Use the factor list to decide what to discuss or track next. The number itself is less important than whether repeated lifestyle inputs move in a healthier direction.
