BIOLOGICAL AGE
CALCULATOR
Your biological age reflects how well your body is functioning compared to your chronological age. Based on key biomarkers and lifestyle factors, this calculator estimates whether you're aging faster or slower than your years suggest.
// BASIC INFORMATION
Your current age in years
// KEY BIOMARKERS
Measured first thing in the morning at rest
Systolic
Diastolic
Blood sugar measured after 8+ hours fasting
"Good" cholesterol - higher is generally better
// LIFESTYLE FACTORS
// YOUR BIOLOGICAL AGE
ESTIMATED BIOLOGICAL AGE
35
years
Your biological age matches your chronological age.
FACTOR CONTRIBUTIONS
Key insight: This is an estimate based on simplified calculations. For accurate biological age assessment, consider epigenetic testing.

UNDERSTANDING BIOLOGICAL AGE
WHAT IS BIOLOGICAL AGE?
Biological age refers to how old your body appears based on various biomarkers and physiological measures, as opposed to your chronological age (years since birth). Two people of the same chronological age can have very different biological ages depending on genetics, lifestyle, and environmental factors.
KEY MARKERS OF BIOLOGICAL AGE
- Cardiovascular Health: Resting heart rate, blood pressure, and heart rate variability reflect cardiovascular fitness and vascular health
- Metabolic Health: Fasting glucose, insulin sensitivity, and cholesterol levels indicate metabolic function
- Inflammation: Markers like CRP and inflammatory cytokines increase with biological aging
- Telomere Length: Shorter telomeres are associated with cellular aging
- Epigenetic Clocks: DNA methylation patterns provide the most accurate biological age estimates
FACTORS THAT ACCELERATE AGING
- Smoking: +4-10 years biological age
- Chronic stress: +2-4 years
- Poor sleep: +2-3 years
- Sedentary lifestyle: +3-5 years
- Obesity: +2-5 years
- Heavy alcohol use: +2-4 years
- Poor diet: +2-4 years
- Social isolation: +1-3 years
FACTORS THAT SLOW AGING
- Regular exercise: Both cardio and resistance training reduce biological age by 3-9 years
- Quality sleep: 7-9 hours of restorative sleep supports cellular repair
- Healthy diet: Mediterranean-style diets rich in whole foods, vegetables, and omega-3s
- Stress management: Meditation, social connection, and purpose in life
- Caloric restriction: Moderate caloric restriction without malnutrition
- Cold/heat exposure: Hormetic stressors that activate longevity pathways
ABOUT THIS CALCULATOR
This calculator uses a simplified algorithm based on established biomarkers and lifestyle factors. While it provides a reasonable estimate, the most accurate biological age testing uses epigenetic clocks that analyze DNA methylation patterns. Tests like TruAge, GrimAge, and PhenoAge can measure biological age with greater precision.
THE FORMULA EXPLAINED
Our algorithm starts with your chronological age and adjusts based on how your biomarkers compare to optimal ranges:
Base: Chronological age
Heart Rate: +/- years based on deviation from optimal (55-65 BPM)
Blood Pressure: +/- years based on deviation from optimal (<120/80)
Glucose: +/- years based on deviation from optimal (70-90 mg/dL)
HDL: +/- years based on deviation from optimal (>60 mg/dL)
Lifestyle: Adjustments for exercise, sleep, smoking, and alcohol
