Estimate projected lifespan and years remaining using age, sex, lifestyle, and health habits. This free life expectancy calculator gives a simple planning estimate along with milestone ages and a breakdown of factors that can shift the estimate up or down.
Base estimate:
The calculator begins with a simple baseline expectancy that differs by sex.
Lifestyle adjustments:
Smoking, activity, sleep, stress, alcohol, diet, and family longevity adjust the estimate up or down.
Current age:

Planning view:
The result also shows milestone ages and a summary of the factor adjustments used.
A life expectancy calculator can turn general health and habit choices into a simple long-range estimate. Many people use it as a reminder that everyday choices can affect long-term health patterns.
It can also be a useful planning tool when thinking about future milestones and goals.
Your result shows a projected lifespan estimate, years remaining, and the lifestyle factors that influenced the total. This gives you a broad long-term estimate rather than a guaranteed outcome.
Many people find it helpful to focus on the habits that can move the estimate in a better direction over time.
It is only a broad estimate. Real life expectancy depends on many factors this type of calculator cannot fully capture.
Factors like smoking, chronic health conditions, activity, stress, sleep, diet, and family history can all matter.
In many cases, healthier habits can shift the estimate in a more favorable direction over time.
