Air Force BAH calculator

Match the assignment rather than a base nickname

A base name can be a useful starting point, but the ordinary locality BAH lookup uses the permanent duty station ZIP, pay grade, and dependent category. The housing area may be named after a city rather than the installation. A unit designation, a training location, or a neighborhood search does not by itself establish the location authorized for the member’s allowance.

The same source entry applies to the same lookup conditions regardless of the branch selected in this tool. Air Force examples are useful because of where Airmen are assigned, not because the calculator uses another formula. Government quarters, service status, unusual orders, and location exceptions still need the appropriate review. The website cannot determine those facts from a base name and three ordinary inputs.

The Air Force Academy area uses CO046

The United States Air Force Academy’s official visitor information identifies the installation north of Colorado Springs and uses ZIP 80840. The retained 2026 source maps that code to CO046. In the selected annual dataset the area label is “COLORADO SPRINGS, CO”. A city based label can therefore be correct even when it does not contain the full installation name that appears on an address.

The official installation source is https://www.usafa.edu/visitors/. The Academy is an installation example for identifying an area; an address alone does not establish anyone’s eligibility for ordinary locality BAH. Keep the member’s actual status and duty information separate from the location example. The calculator’s grade and dependent inputs cannot resolve an academy specific or training entitlement question without the relevant official guidance.

Dyess shows why the effective period matters

MilitaryINSTALLATIONS lists Dyess Air Force Base in Abilene, Texas with ZIP 79607. That code maps to TX270 in the retained 2026 source. The selected annual label is “ABILENE/DYESS AFB, TX”. This example connects an actual installation address to a published MHA; the displayed amounts are read from the selected annual dataset rather than calculated from an assumed local market change.

The installation record is https://installations.militaryonesource.mil/military-installation/dyess-afb. In the 2026 snapshot, TX270 includes the temporary replacement effective May 16, 2026. Its official notice specifies an expiration of December 31, 2026. Do not apply that replacement to an earlier period or carry it into a later year by assumption. A current table and an actual payment for another effective period can legitimately require different inputs and rules.

Tinker is shown under the Oklahoma City area

Official Air Force housing information identifies Tinker Air Force Base with ZIP 73145. The retained 2026 mapping places that code in OK239, and the selected dataset labels the area “OKLAHOMA CITY, OK”. The absence of the word Tinker from the MHA name is not evidence that the ZIP was unmatched. The rate source describes a housing market area rather than listing every installation inside it.

The official housing source is https://www.housing.af.mil/Home/Installations/Tinker-AFB/. Use installation information to confirm the address and local housing contacts, while using the annual source mapping for the rate area. The rate example does not identify available homes or promise that the allowance will cover a particular lease. Compare actual housing expenses separately from the published amount and keep the selected dependent category visible.

Read grade, dependent category, and annual equivalent together

For a consistent comparison between these areas, hold the grade and dependent category constant. With dependents and without dependents are two source categories; there is no separate addition for every extra family member. The retained 2026 table also has one E-1 entry in each category, without a separate housing reduction for service under four months. Basic pay thresholds should not be imported into the BAH calculation.

The displayed annual equivalent is twelve times the selected monthly amount. That is useful for a constant rate comparison, not for reconstructing a year containing a PCS, a temporary adjustment, a partial month, or another personal change. For a move, write down both locations, the applicable periods, and the source year rather than treating either area’s annual equivalent as a promised calendar year payment.

Use the current import without relabeling the historical record

The available source is 2026, downloaded on November 13, 2026, covering 338 MHA entries and 40,745 usable ZIP codes. The 2027 annual release remains pending here. A December 2026 publication is expected from the usual annual pattern, but no specific release day or projected amount supplies the calculator. These examples remain labeled with the actual available year.

For a personal entitlement or payment question, contact the local Air Force finance office. A continuing eligible member’s rate protection can make a payment differ from a newly published entry, and changes in assignment, grade, dependent circumstances, or eligibility can affect the applicable rule. The calculator has no pay history or authority to decide that question. Use its public inputs and source date to prepare the finance inquiry.
