How BAH Is Calculated in 2026 (And Why Rates Changed)

Basic Allowance for Housing is the second-biggest part of most service members' pay, and it can differ by thousands of dollars a month between two bases. The rates aren't arbitrary. Here is how DoD builds them, and why yours may have changed for 2026.

What BAH is meant to cover

BAH exists so that service members who live off base can afford housing comparable to what civilians with similar incomes rent in the same area. It is designed around two costs: rent and utilities (electricity, heating fuel, water and sewer). Renter's insurance used to be part of the formula but was removed in 2015.

Because rents vary so much, DoD prices housing separately in 299 Military Housing Areas across the continental United States, Alaska and Hawaii, plus 39 county cost groups for locations outside those areas. Your area is decided by the ZIP code of your permanent duty station — not where you actually live. Service members stationed overseas receive Overseas Housing Allowance instead.

Step 1: collecting rental data

Each year the Defense Travel Management Office collects rental costs for every housing area. Collection happens in the spring and summer, when moves peak and rental markets are most active. The data comes from verified vacancy listings: multiple listing services, commercial rental databases, listing websites, property management companies, and input from installation housing offices. The goal is the median current market rent for specific types of homes, not the average of what service members happen to pay.

Step 2: matching homes to pay grades

DoD doesn't price every grade separately. It uses a set of housing standards, sometimes called anchor points, that tie grades to home types. Roughly, junior enlisted members are matched to apartments, mid-grade NCOs with families to townhouses, and senior NCOs and officers to single-family homes with more bedrooms. Grades between the anchors are filled in by interpolation. That is why rates climb steadily as you move up in rank, and why the jump between some adjacent grades is small.

Two quirks of that design show up in the tables. First, grades E-1 through E-4 share one rate in every housing area. Second, O-8, O-9 and O-10 receive the same rate as O-7.

Step 3: with or without dependents

Each grade gets two rates. The with-dependents rate assumes a larger home than the without-dependents rate. In San Diego, for example, an E-5 receives $3,975 a month with dependents and $3,147 without — a difference of $828. The number of dependents doesn't matter: a member with one child and a member with six receive the same amount.

Step 4: the 5% cost-share

BAH isn't designed to cover 100% of housing costs. Since 2015 Congress has built in a member cost-share that grew by one percentage point a year until it was capped at 5% in 2019. In practice, rates are set so the average member pays about 5% of typical housing costs out of pocket — for 2026, roughly $93 to $212 a month depending on rank. The cost-share is calculated from national averages, so it's the same dollar amount for a given grade everywhere.

Why rates changed for 2026

The 2026 rates took effect January 1, 2026. On average, BAH rose 4.2%, a slower increase than the 5.4% seen in both 2024 and 2025. DoD projects about $29.9 billion in BAH payments to roughly one million service members this year.

The average hides a lot of variation. Rates follow local rental markets, so an area where rents climbed quickly may see a large jump, while an area with flat or falling rents can see a small increase or even a decrease. A change in the rental data for a particular home type can also move some grades more than others in the same area.

Rate protection: why a decrease may not affect you

If your area's rate drops, you probably keep the old one. Under individual rate protection, a member who is already at a duty station keeps the higher of last year's rate or the new rate. Protection continues until you make a permanent change of station, are reduced in grade, or change dependency status. Promotions don't end it — you simply move to the new grade's rate if that is higher. New arrivals get the currently published rate.

Dual-military couples

When two service members are married to each other and have no other dependents, each receives BAH at the without-dependents rate for their own grade and duty station. If they have children, one member — usually the higher-ranking one — receives the with-dependents rate and the other receives the without-dependents rate. Rules differ when the couple lives in government housing or is stationed apart, so check with your finance office when your situation changes.

Common misunderstandings

• "BAH is based on where I live." It is based on your duty station's ZIP code. Living farther out doesn't change it.
• "I have to spend all of it on rent." BAH is an allowance, not a reimbursement. If you find cheaper housing, you keep the difference; if you pick pricier housing, you pay the difference.
• "BAH is taxable." It isn't. BAH is a non-taxable allowance and doesn't appear as wages on your W-2.
• "More kids means more BAH." There are only two rates per grade: with or without dependents.

An example from the tables

An E-4 without dependents stationed at Camp Lejeune, North Carolina receives $1,323 a month in 2026. The same E-4 in San Diego receives $2,763. Both share one basic pay — the entire difference is local housing costs. You can compare every area side by side in our 2026 BAH rates chart.
