health calculator
Estimate body age from lifestyle and health inputs.
Save this assessment to track how improving your exercise, sleep, and weight reduces your biological score.
Estimated body age
32 years
Formula
Body age = age + lifestyle and health-factor adjustmentsThis is a simple wellness estimate based on BMI, resting heart rate, exercise frequency, and sleep.
Step by step
Example
A 35-year-old with moderate BMI, regular exercise, and good sleep may estimate slightly younger than chronological age.

Guide
Body age is a health simulation that compares your chronological age against an estimated biological age based on physical and lifestyle markers. These markers include body mass index (BMI), resting heart rate, physical activity, and sleep hygiene.
The score highlights the impact of lifestyle choices, indicating whether your habits are supportive of long-term biological youth or accelerating age markers.
Small lifestyle shifts can reduce your estimated body age. Maintaining a healthy weight range, engaging in regular cardiovascular and resistance exercise (4+ days per week), sleeping 7-9 hours per night, and lowering your resting heart rate through fitness are the primary drivers.
Biological age
The physiological condition of your organs and cells relative to chronological time.
Resting heart rate
The number of heartbeats per minute while sitting quietly, indicating fitness.
Sleep hygiene
Habits and practices that support consistent, high-quality nightly rest.
No. Body age is a simplified motivational simulation that summarizes standard lifestyle risk factors. It is not an official medical test or indicator of life expectancy.
A lower resting heart rate is generally an indicator of an efficient, well-conditioned cardiovascular system, which is associated with lower health risks.
