How does the calculator work?
The calculator uses your date of birth, biological sex, country of residence, body metrics, and lifestyle factors to estimate life expectancy. The algorithm draws on published epidemiological data and applies validated adjustments for each factor.
Is this medically accurate?
This tool provides a statistical estimate based on population-level data, not a medical diagnosis. Individual outcomes vary greatly. It is designed for educational purposes only — please consult a healthcare professional for personalised advice.
What factors affect lifespan the most?
Smoking cessation and regular physical activity have the largest positive impact. Sleep quality, stress management, alcohol moderation, and maintaining a healthy body weight also significantly contribute to longevity.
Is my data stored or shared?
No. All calculations happen entirely in your browser. None of your personal information is sent to any server, stored in a database, or shared with third parties.
