About the Life Expectancy / Longevity Calculator

This Life Expectancy / Longevity Calculator provides an educational estimate of your life expectancy by starting from a simple, sex-specific baseline (Global vs High-income averages) and then applying small, transparent lifestyle modifiers (smoking, physical activity, BMI category, blood pressure, diabetes, alcohol, sleep, diet quality, social connection, and basic safety habits).

The goal is clarity: you can see how everyday choices may nudge long-term risk up or down. Estimates do not use country-exact life tables, genetics, or medical history and cannot predict individual outcomes. Use them to identify practical next steps — quit smoking, move more, keep BP and glucose controlled, improve sleep and diet, strengthen social ties, and wear seatbelts/helmets.

  • Baseline: pick Global or High-income averages (female ≈ 75/83; male ≈ 71/79 at birth).
  • Adjustments: conservative, directional year-shifts (e.g., smoking −6 y, activity +2 y, uncontrolled BP −2 y).
  • Output: estimated expected age and years remaining today, plus focused tips.

Educational use only — not medical advice or a diagnosis. No personal data is stored; calculations run locally in your browser.

FAQ

  • How does this calculator estimate life expectancy?
    It starts from a sex-specific baseline (Global or High-income averages) and applies small, transparent lifestyle adjustments (e.g., smoking, activity, BMI category, blood pressure, diabetes, alcohol, sleep, diet, social ties, safety).
  • What’s the difference between “expected age” and “years remaining”?
    Expected age is the estimated age at death; years remaining is the difference between that estimate and your current age.
  • Why not use my exact country’s life tables?
    To keep the tool simple and privacy-friendly. For precise, country-specific figures, consult official statistics or actuarial tables.
  • How big is the impact of smoking?
    Smoking is one of the strongest negative factors. Quitting typically provides the largest improvement in long-term risk.
  • Does exercise really add years?
    Regular activity (≈150 min/week moderate or 75 min/week vigorous) is associated with better outcomes and fewer chronic-disease risks.
  • Why use BMI categories instead of exact BMI?
    Categories keep inputs simple while reflecting broad risk patterns. For nuance, use Body Fat, Waist-to-Height, or WHR tools.
  • How do blood pressure and diabetes affect the result?
    Uncontrolled hypertension and diabetes are linked to higher risk. Keeping them well-managed can improve estimates.
  • What about alcohol and sleep?
    Excess alcohol and chronically short/long sleep are associated with higher risk. Moderate intake and 7–9 hours/night are preferable.
  • Do social connections and safety habits matter?
    Yes. Sustained social ties and basic safety (seatbelts/helmets) are linked to lower mortality risk.
  • Is this medical advice?
    No. It’s an educational estimate and cannot predict individual outcomes. Talk to a clinician for personalized assessment.
  • Is my data stored?
    No. Inputs run locally in your browser; nothing is sent to a server.
  • Can I improve my estimate?
    Yes — quit smoking, be active, keep a healthy weight, control BP/glucose, sleep 7–9 h, improve diet quality, limit alcohol, and use basic safety.
