Sources & Change Log

By Mark Ellison, Editor · Updated October 23, 2026

This page lists every source document behind the site's calculators and charts, and every change made to the data. Nothing on the site uses a number that does not trace back to one of these documents.

Source documents

Each row is one primary document: an Army directive or score table, a Marine Corps order or message, an Air Force manual or AFPC chart, a Navy message, a DFAS pay table, or a congressional document on the 2027 pay raise. The "Checked" column is the last date the data file was compared with the document.

Source: the publishers' own sites, linked in each row; checked October 23, 2026.

When a service publishes a newer version, the old document stays listed until every page that uses it has been updated.

Change log

Every change to a data table or to the facts on a page is recorded here with the date, the page, the document behind it, and a short description. A page's "Updated" date changes only when an entry for that page is added to this log.

Reporting an error

If a number on the site does not match a source document, email the address on the contact page with the document number and the page or table where the difference appears. Confirmed errors are corrected in the data file, the affected pages are rebuilt, and the correction is logged here.
