About this tool

Honest, statistics-based life expectancy estimates for the UK.

This is an independent tool with no product to sell and no agenda. It aims to give realistic, defensible estimates rather than aspirational ones, and to be transparent about its method and limits. It does not store anything you enter; the calculation runs entirely in your browser.

Honesty about the figures

The underlying coefficients are grounded in the direction of published research but are not a substitute for clinical assessment. Where the evidence is uncertain, the tool errs toward caution and says so.
