Biological Age Calculator

Biological age (also called physiological age or body age) reflects how old your body is at a cellular and functional level, as opposed to your chronological age (years since birth). People who exercise regularly, maintain a healthy weight, and avoid smoking typically have a lower biological age than their chronological age.

This calculator uses a scoring approach based on validated risk factors linked to accelerated or decelerated biological aging, including BMI, sleep duration, physical activity, smoking status, alcohol intake, stress, diet quality, and resting heart rate. Each factor adjusts your estimated biological age up or down from your chronological baseline.

Research strongly suggests biological aging can be slowed and partially reversed. Epigenetic clock studies (such as Horvath's methylation clock) show lifestyle factors can shift biological aging. Quitting smoking, exercising, losing excess weight, improving sleep, and managing stress are the most impactful interventions.

No. This is a general wellness estimation tool based on published research on aging risk factors. It is not a medical diagnostic. True biological age measurement uses biomarkers such as telomere length, DNA methylation clocks, or blood panel markers. Consult a healthcare provider for clinical assessment.

Research identifies physical activity, not smoking, healthy weight, adequate sleep (7-9 hours), low-to-moderate alcohol intake, stress management, and a diet rich in fruits, vegetables, and whole grains as the strongest modifiers of biological age. Combining all five healthy lifestyle factors can reduce functional age by a decade or more.
