All About Basic Allowance for Housing (BAH)

What Is BAH and How Is It Determined?

BAH is a non-taxable monthly stipend provided to active-duty military members who do not reside in government-owned housing. The amount you receive is based on:

  • Your pay grade
  • Dependency status (with or without dependents)
  • The cost of housing in your duty station’s ZIP code

Because housing costs vary widely from one duty location to another, BAH rates are tailored to reflect local market conditions. You can use the BAH calculator on this page to estimate your current allowance and explore how it could support your journey to homeownership.

How BAH Rates Are Calculated

The Department of Defense (DoD) reviews rental data annually to set BAH rates. These rates are based on:

  • Median rental costs in the local civilian market
  • Average utilities and renter’s insurance
  • Your rank and dependency status

Higher-cost areas have higher BAH rates, and service members in senior ranks or with dependents generally receive a larger allowance.

BAH is adjusted each year to reflect local real estate trends. If you get promoted or your dependency status changes, your BAH may also adjust to reflect those life changes.

BAH Updates: How Often and Why?

BAH rates are updated every January 1st, based on shifts in the housing market. If rental prices rise in your area, your new BAH will reflect that increase in the following year. On the other hand, if your personal situation changes—like a promotion or a change in your dependent status—your updated BAH will typically take effect the next month.

What If Your BAH Drops?

Your BAH amount may decrease if your rank changes or your dependency status is updated—for example, if your dependent child moves out of the household.

However, there’s good news: your BAH cannot be reduced due to local market shifts while you're stationed in the same location. Thanks to Rate Protection, also known as the Grandfather Clause, you’ll continue receiving the higher BAH rate as long as:

  • You remain at your current duty station.
  • Your rank doesn’t change.
  • Your dependency status stays the same.
  • This provides a valuable layer of financial predictability during your tour.

Can You Use BAH as Income for a VA Loan?

Yes—lenders do consider BAH as qualifying income when applying for a VA home loan. In many cases, BAH can cover your entire monthly mortgage payment, especially in moderately priced housing markets.

If you’re buying in a more expensive area, you may need to supplement your BAH with additional income. A VA loan specialist can help you understand what home price range fits your situation and how best to use your BAH in the financing process.

Military Couples and Dual BAH

For dual-military couples, BAH can get a bit more nuanced. Here’s how it works:

  • Both service members receive their own BAH, even after marriage.
  • If the couple has dependents, only one of you can receive the with-dependent BAH rate.
  • Typically, the higher-ranking spouse claims the with-dependent rate, while the other receives single BAH.
  • If you're stationed apart, the service member living with the dependents receives the with-dependent BAH.

Planning together can help you make the most of your combined housing benefits.
