How a promotion changes your paycheck
When you sew on a new rank, your basic pay jumps to whatever the new paygrade pays for your years of service. The 2026 pay tables are tiered first by paygrade and then by YOS columns at <2, 2, 3, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, and 40 years — so a promotion that lands near a YOS threshold can stack the longevity step on top of the paygrade raise.
Among enlisted promotions, E-8 → E-9 is one of the largest jumps — about $1,000/month at 10 YOS on the 2026 table; E-6 → E-7 (the senior NCO transition) and E-3 → E-4 are also substantial (roughly $550 and $460/month at typical YOS). On the officer side, O-3 → O-4 is the standard mid-career promotion — frequently a $1,000+ monthly raise depending on YOS column ($1,100.10/month at 12 YOS on the 2026 table). Warrant promotions run roughly $440 to $712/month at 12 YOS for W-1 → W-2 through W-3 → W-4 on the 2026 table.
What the calculator does NOT include
This page shows the basic-pay change only. A real-world "promotion paycheck" also depends on:
- BAH — BAH is published per paygrade (37 U.S.C. § 403). In the 2026 tables, E-1 through E-4 share one rate in every MHA, so promotions within that band leave BAH unchanged; from E-4 → E-5 upward, and at every warrant and officer step through O-7, promotion moves you to a higher published rate at your duty station. Use the BAH Comparison tool to model the new rate.
- BAS — flat monthly amount that does not change at promotion (enlisted: $476.95, officer: $328.48 in 2026).
- Special and incentive pays — many are tied to position (HDIP, SDAP, FLPB, sea pay, aviation incentive). A promotion that also moves you to a new billet may add or remove these pays.
- Federal income tax — basic pay is fully taxable, so a $400/month raise at the 22% bracket is roughly $281 in your pocket after federal income tax ($88) plus FICA at 7.65% ($31). Use the Federal Tax Withholding tool to model take-home.
- Retirement multiplier — under both the legacy High-3 system and the BRS 2.0% multiplier, a promotion captured in the high-3 window (your highest 36 months of basic pay — for most members, the final three years) raises your pension for life. Promote 18 months before retirement, and only half of your high-3 earnings reflect the new rate; promote three or more years out, and the entire high-3 window reflects the higher pay.
- TSP matching (BRS members) — if your contribution is set as a percent of basic pay, the dollar amount you save automatically rises with the promotion. Same for the agency match (up to 4%, plus the 1% automatic contribution).
Compounding over a career
Even a modest $300/month raise adds up to about $36,000 over 10 years and roughly $108,000 over a 30-year career — before counting the knock-on effects on your BAH tier, retirement pension, TSP match, and post-service Social Security (basic pay is FICA wages, so a higher rate builds a higher earnings record). The earlier in a career you promote, the larger the lifetime impact.
For reference: the 2026 across-the-board military pay raise is 3.8% per the FY2026 NDAA (P.L. 119-60), applied uniformly to all grades — the larger junior-enlisted targeted raise was 2025, not 2026. Promotions stack on top of that 2026 baseline; the promotion raise is independent of the annual raise.
Time-in-grade and time-in-service rules
Promotion eligibility depends on minimum time-in-service (TIS) and time-in-grade (TIG) requirements set by service-specific instruction. These vary across the services and across grades — Air Force/Space Force AFI 36-2502, Army AR 600-8-19, Navy BUPERSINST 1430.16H (the Advancement Manual), Marine Corps MCO P1400.32D (enlisted; officers MCO 1400.31D), and Coast Guard COMDTINST M1000.2C each set their own minimums. Officer promotions are governed by DOPMA (Defense Officer Personnel Management Act, 10 U.S.C. §§ 611-643) for the active component and ROPMA (Reserve Officer Personnel Management Act, 10 U.S.C. §§ 14001-14507) for the reserve component, with promotion zones (primary, below-zone, above-zone).
This calculator does not encode service-specific eligibility. For the actual TIS/TIG tables per service, use the Enlisted Promotion Timeline and Officer Promotion Timeline tools on this site.
