Basic Pay Calculator

Basic pay under 37 U.S.C. § 203 is the only taxable element of regular military compensation. The recurring allowances — BAH, BAS, FSA, DLA at PCS — are excluded from gross income as qualified military benefits under 26 U.S.C. § 134, and pay earned in a designated combat zone can be excluded under the Combat Zone Tax Exclusion (CZTE) of 26 U.S.C. § 112 (IRS Publication 3 covers the details). 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 rate tables are reproduced in DoD FMR Volume 7A, Chapter 1 (Tables 1-7 through 1-10), which defers to the DFAS-published tables for current rates.

Longevity raises run on the pay base date, not the date of rank. 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 move to the next YOS bucket is effective on the anniversary of the pay base date itself, not on the first day of the following month. A member with a pay base date of 15 January 2022 hits 4 YOS on 15 January 2026 and is paid at the pay grade × over-4 column effective 15 January 2026. A month that contains a longevity increase is paid partly at the old rate and partly at the new one, computed on a 30-day basis — the daily rate is 1/30 of the monthly rate (DoD FMR Volume 7A, Chapter 1, ¶3.2). The one exception is a pay base date of 29 February: the longevity increase then begins on 1 March in non-leap years and on 29 February in leap years (DoD FMR Volume 7A, Chapter 1, ¶2.4.2). If the bump never shows up on the LES for the month you crossed the boundary, that is worth a finance-office visit.

Pay base date vs DIEMS vs DOR. Three different dates appear on the LES and produce different pay outcomes. Pay base date (PBD) — the FMR's "basic pay date," which the Army calls the pay entry basic date, the Navy and Marine Corps the pay entry base date, and the Air Force simply the pay date (DoD FMR Volume 7A, Chapter 1, ¶2.1.1.1) — 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, unless the member has a DIEMS on or after 1 August 1986 and elected REDUX with the Career Status Bonus, or opted into BRS during the 1 January – 31 December 2018 election window (open to active-duty members with less than 12 years of service on 31 December 2017 and Reserve Component members with fewer than 4,320 retirement points on that date); DIEMS 1-Jan-2018 forward = Blended Retirement System (BRS) automatically. Date of Rank (DOR) drives promotion-zone eligibility but does not affect basic pay directly. Members with broken service can have PBD, DIEMS, and DOR that disagree by several years; the servicing personnel office is responsible for the statement of service that establishes the correct PBD from DD-214s and prior-service records (DoD FMR Volume 7A, Chapter 1, ¶2.1.1.2).

Officer (Prior Enlisted) — the O-1E through O-3E columns. Officers credited with over 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 recognize the prior years of service and produce a meaningfully higher basic pay for as long as the officer serves in grades O-1 through O-3. The eligibility test under 37 U.S.C. § 203(d) (DoD FMR Volume 7A, Chapter 1, ¶2.3.1) is over 4 years — at least 4 years and 1 day — of cumulative active enlisted and/or warrant officer service, or, on the points path, more than 1,460 retirement points credited for enlisted and/or warrant officer service under 10 U.S.C. § 12732(a)(2). 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.
