Acceptance of Terms By accessing and using the Marine Corps PEBD Calculator or its companion Basic Pay Comparison page (together, the "Tool"), you agree to be bound by these Terms of Service.

Service Description The PEBD Calculator is a reference tool designed to assist users in understanding creditable service calculations under Marine Corps PAA 04-25. It performs date arithmetic and service period analysis to estimate Pay Entry Base Dates (PEBDs). The Basic Pay Comparison page is a companion reference tool that estimates the month-by-month basic pay difference between two PEBD scenarios (the PEBD of record and a recalculated PEBD) using a basic pay table embedded in the page. Pay figures are estimates produced with a synthetic 30-day-month proration method and rates effective only through the date shown on the page; they are not a pay record and are not a Defense Finance and Accounting Service (DFAS) computation. --- ## 3.
