Use this evidence-based calculator to predict your potential lifespan based on key lifestyle, health, and behavioral factors. Identify which areas of your life may be reducing or extending your longevity.
Medical Disclaimer: This tool provides general educational estimates. Consult a registered dietitian or doctor for personalized advice.
Note: This calculator provides estimates based on population studies and statistical averages. Individual results may vary. The algorithm incorporates factors from longitudinal studies including the Framingham Heart Study, Nurses' Health Study, and other longevity research.
Factors weighted based on meta-analyses of their impact on mortality risk. This is not medical advice.
This calculator helps estimate your potential lifespan using peer-reviewed health, behavior, and demographic data. Follow these steps:
This estimate is based on large-scale cohort studies like the Framingham Heart Study, Nurses' Health Study, and WHO mortality data.

This calculator provides a statistical estimate based on population-level research, not an individual prediction. While the factors included have strong scientific support for influencing longevity, personal outcomes may vary due to unmeasured factors like genetics, environmental exposures, access to healthcare, and random events. Consider the results a general guideline rather than a precise forecast.
Yes, research consistently shows that lifestyle modifications can significantly impact longevity. The "big four" behaviors—not smoking, maintaining healthy weight, regular physical activity, and healthy diet—are associated with an 11-14 year increase in life expectancy compared to having none of these healthy habits. Even adopting these behaviors in middle age shows measurable benefits.
Strong social connections impact health through multiple mechanisms: reducing chronic stress and inflammatory responses, encouraging healthier behaviors, providing practical support during illness, and fulfilling fundamental psychological needs. Meta-analyses suggest the mortality risk of social isolation is comparable to smoking 15 cigarettes daily and exceeds the risks of obesity and physical inactivity.
BMI has limitations as it doesn't distinguish between muscle and fat mass or account for differences in body composition between ethnicities, athletes, and elderly populations. However, at the population level, BMI ranges still correlate with mortality risks in a J-shaped curve. For individuals with high muscle mass or certain ethnic backgrounds, BMI recommendations may need adjustment.
Twin studies suggest approximately 20-30% of lifespan variation is attributable to genetics. Having relatives who lived past 95 increases your odds of longevity, but lifestyle remains more influential. Studies of centenarians (people who live to 100+) show that even with "good genes," environmental and behavioral factors play crucial roles in achieving exceptional longevity.
