This adjusts a rough baseline using broad averages. It is not a medical calculation and cannot account for your individual health.

This free life expectancy predictor gives a rough estimate of how long you might live based on a few lifestyle inputs: your age, sex, smoking status, exercise, diet and alcohol use. It starts from a general baseline and nudges it up or down using broad population averages. Everything runs in your browser and nothing is stored.
