Promotion Back Pay Calculator

Work out what you're owed when pay lags behind your promotion effective date (2026 pay tables)

Your promotion

Use the bracket on your LES at the time of the promotion.

This is on your promotion order — not the date you pinned on or the date pay caught up.

Enter the grade you were promoted from and to, your years of service, and the effective date from your promotion order. Press Calculate Back Pay to see the monthly raise, the unpaid window, and what finance owes you.

Estimates only, based on 2026 DFAS basic pay and the DoD FMR Volume 7A convention of 30 days per month at 1/30 of monthly pay per day. Basic pay only — allowances and special pays are not included. Your finance office makes the final determination.
