nderstanding life expectancy isn’t about predicting the future—it’s about gaining perspective. Whether you’re planning retirement, setting personal goals, or simply curious about health statistics, knowing your estimated remaining years can be a surprisingly valuable insight.
Our Life Expectancy Calculator is a simple, free online tool that helps you quickly estimate how many years you may have left and your projected age at death based on your current age and your country’s average life expectancy. It’s designed for clarity, speed, and accessibility—no complex forms, no unnecessary questions.
This tool uses two main inputs: your current age and your country’s average life expectancy. With this, it calculates:
