Retirement healthcare
Estimates draw on Fidelity and KFF figures, and those are re-checked every month, so the numbers behind your plan stay current rather than drifting a year out of date.
Method
Every number on this site comes from somewhere, and that source is written down. Where the evidence is genuinely unsettled, this page says so rather than rounding it into false confidence.

Next evolution
The aim is that you can sit down once a year, work through this in an hour, and leave with a short written plan you would actually be willing to show someone.

What care costs depends enormously on where you live and what kind of help you need. The defaults behind those estimates are re-checked monthly against CareScout survey data.
New research on what actually adds healthy years is read every quarter. A person decides whether it changes anything, so a single study never moves your score on its own.
