Basic Pay Calculator

Basic pay under 37 U.S.C. § 203 is the only fully taxable element of regular military compensation. Every other recurring entitlement — BAH, BAS, FSA, hazardous-duty pay in a combat zone, DLA at PCS — is either non-taxable, exempt under the Combat Zone Tax Exclusion (CZTE) of 26 U.S.C. § 112, or covered by IRS Publication 3. The Calendar Year 2026 basic-pay table was published by DFAS following the FY2026 National Defense Authorization Act and incorporates the across-the-board pay raise under the statutory formula in 37 U.S.C. § 1009 — the FY2026 NDAA (P.L. 119-60) did not authorize an alternative, so the automatic ECI-based 3.8% raise took effect 1 January 2026. The table is reproduced in DoD FMR Volume 7A, Chapter 1.

Longevity raises run on time-in-service, not anniversary date. The pay table is structured by pay grade × years-of-service (YOS) buckets — <2, 2, 3, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40. The promotion to the next YOS bucket happens on the first day of the month following the date the member crosses the boundary, not on the actual anniversary date. A member with a pay base date of 15 January 2022 hits 4 YOS on 15 January 2026 and moves to the next pay grade × 4 YOS column on 1 February 2026. The 16-day gap between the boundary and the pay bump is normal and is not a finance error.

Pay base date vs DIEMS vs DOR. Three different dates appear on the LES and produce different pay outcomes. Pay base date (PBD) drives the longevity column in the basic-pay table. Date Initially Entered Military Service (DIEMS) drives retirement system eligibility — pre-8-Sep-1980 = Final Pay system, 8-Sep-1980 through 31-Dec-2017 = High-3, 1-Jan-2018 forward = Blended Retirement System (BRS). Date of Rank (DOR) drives promotion-zone eligibility but does not affect basic pay directly. Members with broken service often have PBD, DIEMS, and DOR that disagree by several years; finance offices can reconstruct the correct PBD from DD-214s and AD-record statements.

Officer (Prior Enlisted) — the O-1E through O-3E columns. Officers with at least 4 years of active enlisted or warrant officer service before commissioning receive pay at the O-1E, O-2E, or O-3E column rather than the standard O-1, O-2, or O-3 column. The prior-enlisted columns reflect a recognition of the prior years of service and produce a meaningfully higher basic pay through the first 3 commissioned years. The eligibility test under 37 U.S.C. § 202(a)(3) is at least 1,460 days (4 years) of cumulative active enlisted or warrant time. Officers transitioning past O-3E into O-4 fall into the standard O-4 column.

Retired-pay base point. Basic pay drives the High-3 average that anchors retired pay for members entering service between 8 September 1980 and 31 December 2017. The High-3 average is the mean of the highest 36 months of basic pay, regardless of whether those months are contiguous — a member who held a higher pay grade for 24 months and a lower grade for 12 months at higher YOS columns picks whichever 36 months produce the highest mean. The High-3 calculation is in DoD FMR Volume 7B, Chapter 3.

Authorities: 37 U.S.C. § 203 (Basic pay); 37 U.S.C. § 202 (Officer pay; prior enlisted); 26 U.S.C. § 112 (Combat Zone Tax Exclusion); DoD Financial Management Regulation Volume 7A, Chapter 1 and Volume 7B, Chapter 3; FY2026 National Defense Authorization Act, Section 601; DFAS Pay Tables effective 1 January 2026. The pay table reproduced in the calculator above matches the DFAS-published table for CY2026; verify any individual entitlement against your LES and finance office before relying on it for major financial decisions.
