BAH Calculator

Introduction

Basic Allowance for Housing (BAH) is money the military pays you each month to help cover your housing costs when you live off base. The amount you get depends on three things: where you are stationed, your pay grade, and whether you have dependents.¹ BAH rates are reviewed every year using current rental market rates, the average cost of utilities, and home type and number of rooms.¹

Our BAH Calculator looks up your monthly and annual housing allowance for a duty station, rank, and year from 2022 to 2026 in the rate tables published by the Defense Travel Management Office.³ Just pick your location, enter your pay grade, and choose your dependency status. The tool will show your full BAH rate, your annual total, and the partial BAH amount paid to those living in government quarters. You can also compare how rates have changed over the past five years with a built-in chart and table.

This calculator gives you the housing allowance numbers you need, whether for a PCS to a new base or a household budget.

How to Use Our BAH Calculator

Enter your duty station, pay grade, dependency status, and rate year below. The calculator will show your monthly and annual Basic Allowance for Housing (BAH) amount.

Duty Station Location: Type your duty station's 5-digit ZIP code, or the name or code of its Military Housing Area (MHA). Pick your match from the list that appears.

Pay Grade: Type your military pay grade, such as E-5, O-3, or W-2. Select the correct rank from the list.

Dependency Status: Choose "With Dependents" if you have a spouse or children. Choose "Without Dependents" if you do not.

BAH Rate Year: Pick the year you want to check. BAH rates change each year, so choose the year that applies to you. For 2022 you can also pick the increased rates that took effect for some areas on October 1, 2022.

Calculate: Press the "Calculate" button to see your BAH results. You can also open "See Past BAH Rates" to compare your rate across multiple years.

What Is BAH (Basic Allowance for Housing)?

BAH stands for Basic Allowance for Housing. It is money the U.S. military pays service members each month to help cover the cost of housing when they live off base. Instead of living in military housing, you get a set amount of money to pay for rent or a mortgage in the area where you are stationed. To see how your BAH compares to typical housing expenses, our Rent Affordability Calculator can help you figure out what you can comfortably spend on rent each month.

How Is BAH Calculated?

The Department of Defense (DoD) sets BAH rates every year.¹ Three things decide how much BAH you get:

Duty station location – Each base is assigned a Military Housing Area (MHA). Places where rent is high, like San Francisco or New York City, have higher BAH rates. Places where rent is low get smaller rates. Our Cost of Living Calculator can help you compare expenses across different duty station areas.
Pay grade – Higher-ranking service members receive more BAH. An O-5 gets more than an E-3, for example.
Dependency status – If you have a spouse or children, you get a higher rate than someone without dependents.

What Is Partial BAH?

Partial BAH is a smaller, flat payment given to service members without dependents who live in government-provided housing, like barracks. This amount does not change based on location. It only changes based on pay grade.⁴

When Do BAH Rates Change?

New BAH rates take effect on January 1 each year, and the DoD usually releases them in mid-December.¹ The rates are set from current rental market rates, the average cost of utilities, and home type and number of rooms.¹ If housing costs go up in your area, your BAH rate will usually go up too. BAH rates also include individual rate protection: if rates fall, you keep the rate you received at the time of your move, and your rate changes only when you are assigned a new duty station, have a reduction in pay grade, or change your dependent status.¹

Who Qualifies for BAH?

All active-duty service members who do not live in government housing can receive BAH. Reserve and National Guard members called to active duty for 31 or more days, or for any length in support of a contingency operation, receive BAH; on other orders of 30 or fewer days they receive a reduced rate, BAH-RC.⁵ BAH is not taxed, which means you keep every dollar of it.¹ Since BAH is tax-free, it effectively increases your total compensation.

Formulas used

Monthly BAH (published rate for the MHA, pay grade and dependency status) ³

\text{Monthly BAH} = R_{\text{year}}\left(\text{MHA},\ \text{grade},\ \text{dependency}\right)

Rate by dependency status

R = \begin{cases} R_{\text{with}} & \text{with dependents} \\ R_{\text{without}} & \text{without dependents} \end{cases}

Annual BAH

\text{Annual BAH} = \text{Monthly BAH} \times 12

Year-over-Year Change

\Delta\% = \frac{\text{BAH}_{\text{year}} - \text{BAH}_{\text{year}-1}}{\text{BAH}_{\text{year}-1}} \times 100

Frequently asked questions

Is BAH taxable income?

No. BAH is excluded from your federal gross income, so you do not pay federal income tax on it.² You keep the full amount each month.

What happens to my BAH if I get promoted?

Your BAH goes up when you move to a higher pay grade. The new rate starts on the same date your promotion takes effect.

Can my BAH rate go down if local rents drop?

No, as long as you stay at the same duty station. Under the DoD's individual rate protection, you keep the rate you received at the time of your move, and your rate changes only when you are assigned a new duty station, have a reduction in pay grade, or change your dependent status.¹

Do I lose BAH if I move into on-base housing?

Yes. If you move into government-provided housing, your full BAH stops. Service members without dependents living in barracks may receive a smaller partial BAH instead.

Do I have to spend all my BAH on housing?

No. BAH is yours to use however you want. If you find housing that costs less than your BAH, you keep the extra money. If your housing costs more, you pay the difference out of pocket.

Does BAH cover utilities?

Yes. BAH rates are calculated using current rental market rates, the average cost of utilities, and home type and number of rooms.¹

What is a Military Housing Area (MHA)?

An MHA is a geographic area the DoD uses to group duty stations with similar housing costs. Each MHA has its own BAH rate. Your BAH is based on the MHA assigned to your duty station, not your home address.

Can I get BAH if I am in the Reserves or National Guard?

Yes. A Reserve or National Guard member called to active duty for 31 or more days, or for any length in support of a contingency operation, receives BAH. On other orders of 30 or fewer days, BAH-RC is paid from the first day of active duty.⁵

Do both military spouses get BAH in a dual-military couple?

Yes, but with limits. When neither has a dependent, each is treated as a member without a dependent. If they have children and live off base, only one of them may receive the with-dependent rate, and they choose which one.⁵

What is the difference between BAH and OHA?

BAH is for service members stationed in the United States. OHA stands for Overseas Housing Allowance and is for those stationed outside the U.S.² OHA works differently and has its own rates and rules.

How do I know which MHA my base falls under?

Use the location search in this calculator. Type your duty station's 5-digit ZIP code and the tool looks up the Military Housing Area that ZIP code belongs to.³ You can also search by MHA name or code.

Does getting married change my BAH?

Yes. When you get married, your dependency status changes to "with dependents," which gives you a higher BAH rate. The increase starts once your records are updated.

What happens to my BAH during a PCS move?

During a PCS, you receive BAH based on your old duty station until you report to your new one. Housing allowance for the new duty station starts on the day you report there.⁵

Can I use BAH toward a mortgage instead of rent?

Yes. Many service members use their BAH to pay a mortgage. The military does not require you to rent. You can buy a home and apply your BAH toward your monthly mortgage payment.

Why is my BAH different from what a friend at the same base gets?

BAH depends on pay grade and dependency status, not just location. A higher-ranking service member or someone with dependents will get a larger amount than a lower-ranking member without dependents at the same base.
