How to Use the Comprehensive Life Expectancy Calculator

A life expectancy calculator is a tool that uses information about your genetics, health, lifestyle, and medical history to provide an estimate of how long you might live, based on statistical models and known health correlations. The Comprehensive Life Expectancy Calculator included in the code above is an interactive web-based tool designed to give you an engaging, data-driven prediction about your future longevity.

What the Calculator Does

The calculator doesn’t just output a single number—it evaluates a variety of factors ranging from family history to lifestyle choices. By combining genetics, health metrics, and daily habits, it helps users better understand how each element might influence their overall life expectancy.

Unlike a simple age predictor, this tool offers feedback about which factors increased or decreased your expected years. For example, exercising regularly may add years, while smoking could reduce them.
