Quick answer: Basic Allowance for Subsistence (BAS) is normally adjusted once per year, with the new rate taking effect on January 1. The percentage change is tied to the USDA food-cost index—not the military basic-pay raise, promotion cycles, duty station, or the general Employment Cost Index.
For 2026, the official monthly rates are $476.95 for enlisted members, $328.48 for officers, and $953.90 for BAS II when specifically authorized. The authoritative current and historical figures are published in the DFAS BAS rate table.
When Does BAS Change?
The regular BAS adjustment takes effect January 1 and remains the standard published rate for that calendar year. It does not automatically change when a member is promoted or moves to another branch or duty station.
Individual LES amounts can still change during the year because of entitlement dates, duty-status changes, meal deductions, partial months, or retroactive corrections. Those account-level changes are different from the annual nationwide BAS rate adjustment.
What Determines the Annual BAS Increase?
The Department of Defense Military Compensation portal explains that BAS is linked to the USDA food-cost index. Each year’s rate is adjusted using the percentage increase in food prices identified by the USDA.
This is separate from the formula used for military basic pay. Basic-pay raises are generally connected to private-sector wage growth, while BAS is intended to track food costs. Therefore:
- a 3.8% basic-pay raise does not mean BAS will rise 3.8%;
- general CPI is not itself the published BAS formula;
- rank and years of service do not determine the standard BAS adjustment; and
- the enlisted and officer rates can be compared year to year using the official DFAS table.
Official BAS Rate History: 2021–2026
| Effective date | Officer BAS | Enlisted BAS | BAS II |
|---|---|---|---|
| January 1, 2026 | $328.48 | $476.95 | $953.90 |
| January 1, 2025 | $320.78 | $465.77 | $931.54 |
| January 1, 2024 | $316.98 | $460.25 | $920.50 |
| January 1, 2023 | $311.68 | $452.56 | $905.12 |
| January 1, 2022 | $280.29 | $406.98 | $813.96 |
| January 1, 2021 | $266.18 | $386.50 | $773.00 |
These are nationwide standard rates. There were not separate junior-enlisted, senior-enlisted, branch, dependent-status, or duty-location BAS schedules during these years.
How Much Did BAS Increase in 2026?
| Category | 2025 | 2026 | Monthly increase | Approximate increase |
|---|---|---|---|---|
| Enlisted | $465.77 | $476.95 | $11.18 | 2.4% |
| Officer | $320.78 | $328.48 | $7.70 | 2.4% |
| BAS II | $931.54 | $953.90 | $22.36 | 2.4% |
The enlisted annual value rose from $5,589.24 in 2025 to $5,723.40 in 2026, an increase of $134.16 for a full year of entitlement. The officer annual value rose by $92.40.
Why Some BAS Increases Are Much Larger Than Others
Food-price changes vary considerably from year to year. The enlisted rate increased from $406.98 in 2022 to $452.56 in 2023—$45.58 per month—while the change from 2024 to 2025 was only $5.52 per month. That difference reflects the food-cost adjustment mechanism, not promotions or a new rank-tier system.
BAS also reacts after food-price changes have already occurred. A new January rate reflects the applicable index calculation; it is not a real-time grocery reimbursement and is not tailored to prices at a particular duty station.
Does BAS Change When You Get Promoted?
No. Standard BAS has one enlisted rate and one officer rate. Promotion from E-4 to E-5, for example, does not create a higher standard BAS rate. A member moving from an enlisted category to an officer category would use the applicable officer entitlement, but ordinary enlisted promotions do not change the published rate.
Does BAS Change by Branch or Location?
No. The Army, Navy, Air Force, Marine Corps, Space Force and Coast Guard use the same standard officer and enlisted BAS figures. BAS also does not include location-based adjustments. This differs from BAH, which varies by pay grade, dependency status and duty-station ZIP code.
Does BAS Change When You Have Dependents?
No. BAS is intended to offset food costs for the service member. It is not meant to cover a spouse or children, so there is no with-dependent BAS rate. See our BAH versus BAS comparison for the distinction.
Why Did My LES BAS Amount Change Midyear?
A midyear change usually means something happened to the individual account, not that DFAS published a new nationwide rate. Common items to review include:
- partial-month entitlement;
- meal or discounted-meal deductions;
- deployment, temporary-duty or accession status;
- a retroactive correction;
- an overpayment collection; or
- a transition between enlisted and officer entitlement categories.
Compare the entitlement, deduction and remarks sections of the current LES with the prior month. For an unexplained change, take both statements and the relevant orders to the servicing finance office. Online articles cannot determine an individual entitlement from the net deposit alone.
What Is BAS II and Does It Adjust Annually?
BAS II is twice the standard enlisted BAS rate, so it changes when the standard enlisted rate changes. It is not a senior-rank allowance. DFAS states that BAS II may be authorized for an enlisted member assigned to single, unaccompanied government quarters at a permanent station when adequate food storage or preparation facilities and a government mess are unavailable and the government cannot otherwise provide meals.
The military department concerned must specifically authorize BAS II. Living in barracks by itself does not establish eligibility.
Can You Predict Next Year’s BAS Rate?
Food-cost data can suggest the direction of the next change, but unofficial projections should not be presented as a confirmed entitlement. Rounding, the measurement period and the official DoD calculation can cause a forecast to differ from the published figure.
For budgeting, use the current DFAS rate until the next official table is released. Once DFAS publishes the new number, calculate the change with:
Percentage increase = (new monthly rate − old monthly rate) ÷ old monthly rate × 100
For example, the 2026 enlisted calculation is ($476.95 − $465.77) ÷ $465.77 × 100, which is approximately 2.4%.
BAS Adjustment FAQs
How often is BAS adjusted?
Normally once per calendar year, effective January 1.
Is BAS based on the military pay raise?
No. BAS follows the USDA food-cost index described by DoD, while basic pay uses a different compensation framework.
Is BAS adjusted for inflation?
It is adjusted using food-cost changes identified through the USDA index, which is more specific than simply applying the headline inflation rate.
Where are official BAS rates published?
DFAS publishes the current and historical officer, enlisted and BAS II figures. The DoD Military Compensation portal explains the purpose and adjustment method.
What are the current 2026 BAS rates?
See our official 2026 BAS rate guide: $476.95 enlisted, $328.48 officer and $953.90 BAS II when authorized.
