Enter Your Military Housing Details
Enter the monthly 2026 rate for your duty station, pay grade and dependency status. ZIP code and pay grade are included in your result but are not used to retrieve rates automatically.
Your Estimated 2027 Housing Allowance
| Duty Station ZIP | — |
|---|---|
| Pay Grade | — |
| Dependency Status | — |
| 2026 Monthly BAH | — |
| Estimated Rate Change | — |
| Estimated Monthly Increase | — |
| Estimated 2027 Monthly BAH | — |
| Months Selected | — |
This is a mathematical estimate based on the rate and percentage you entered. Actual BAH may differ because DoD sets rates by Military Housing Area, pay grade and dependency status.
How Is 2027 BAH Estimated?
The calculator applies your selected percentage change to your 2026 monthly BAH rate.
Estimated 2027 BAH = 2026 BAH × (1 + Rate Change ÷ 100)
Example: If your 2026 monthly BAH is $2,000 and you enter a projected increase of 3%, the estimated 2027 monthly amount is $2,060.
The annual estimate is calculated by multiplying the estimated monthly amount by 12. The selected-period total uses the number of months you choose.
What Determines Your BAH Rate?
- Duty station: BAH rates depend on the Military Housing Area associated with your duty station.
- Pay grade: Different military pay grades have different housing allowance rates.
- Dependency status: Rates are published for members with dependents and without dependents.
- Annual rate updates: The Department of Defense reviews and publishes BAH rates each year.

BAH Calculator 2027|Estimate Your USA Military Housing Allowance
Planning your military housing budget for 2027? The BAH Calculator 2027 helps U.S. service members estimate their Basic Allowance for Housing using their current monthly BAH rate and an expected rate adjustment.
Basic Allowance for Housing (BAH) is designed to help eligible military members pay for housing when government quarters are not provided. The amount depends mainly on the member's duty station, pay grade and dependency status.
Use the calculator on this page to estimate your monthly and annual housing allowance for 2027. You can enter your 2026 BAH amount, adjust the projected percentage change and calculate an estimate for the number of months you select.
2027 rate update: Official 2027 BAH rates have not been published as of October 31, 2026. The calculator therefore uses your manually entered 2026 rate and an adjustable percentage. Its result is a planning estimate, not an official Department of Defense rate.
What Is BAH?
BAH stands for Basic Allowance for Housing. It is a U.S. military allowance intended to help service members meet housing costs in the local civilian rental market when government housing is not provided.
The Department of Defense determines BAH rates using local housing costs. The allowance is designed around rental housing and average utilities, rather than the actual rent paid by every individual service member.
BAH is not guaranteed to cover all housing expenses. Your actual costs may be higher or lower depending on the home you choose and your personal circumstances. Official DoD BAH information explains how the allowance works.
BAH Calculator 2027: How to Estimate Your Allowance
The calculator uses a simple projection based on your 2026 monthly BAH rate.
Enter the following information:
- Duty Station ZIP Code: Enter the five-digit ZIP code associated with your permanent duty station.
- Pay Grade: Select your military pay grade, such as E-5, E-6, O-3 or another applicable grade.
- Dependency Status: Choose with dependents or without dependents.
- 2026 Monthly BAH Rate: Enter the official monthly amount applicable to your circumstances.
- Estimated Rate Change: Enter a percentage increase or decrease to test a possible 2027 scenario.
- Months Receiving BAH: Select the number of months for your estimated payment period.
Click the Calculate 2027 BAH button to see the estimated monthly amount, annual amount and selected-period total.
Important: The ZIP code, pay grade and dependency status are recorded in the result, but this calculator does not automatically retrieve an official rate from the Department of Defense database. You must enter your actual 2026 monthly rate yourself.
How Is the 2027 BAH Estimate Calculated?
The calculator applies the percentage you enter to your 2026 monthly allowance.
Formula:
Estimated 2027 Monthly BAH = 2026 Monthly BAH × (1 + Percentage Change ÷ 100)
For example, suppose a service member enters a 2026 monthly BAH rate of $2,000 and chooses a hypothetical 3% increase.
| Calculation | Amount |
|---|---|
| 2026 Monthly BAH | $2,000 |
| Assumed Rate Change | 3% |
| Estimated Monthly Increase | $60 |
| Estimated 2027 Monthly BAH | $2,060 |
| Estimated 12-Month Total | $24,720 |
This example demonstrates the calculator's formula. The 3% figure is an assumption, not an announced 2027 BAH increase.
When Will 2027 BAH Rates Be Released?
The Department of Defense normally publishes updated BAH rates annually, with new rates taking effect on January 1.
The 2026 BAH rates were announced on December 11, 2025, and became effective January 1, 2026. The official announcement reported an average increase of 4.2% for 2026. The Defense Travel Management Office provides the official rate information and lookup resources.
As of October 31, 2026, the official 2027 rates have not been published. A specific 2027 increase should not be treated as confirmed until the Department of Defense releases the new figures.
Once the 2027 rates become available, service members should use the official lookup rather than relying on a percentage-based projection.
What Factors Determine Your BAH Rate?
BAH is not one fixed amount for every member of the military. Several factors determine the applicable rate.
1. Duty Station and Military Housing Area
The location of your permanent duty station is an important factor. The Department of Defense uses local rental and utility data to establish rates for Military Housing Areas (MHAs).
The ZIP code helps identify the applicable housing area. A service member stationed in one location may receive a different rate from someone stationed in another area.
2. Military Pay Grade
BAH rates vary by pay grade. An E-4, E-6 and O-3 may receive different housing allowances even when assigned to the same housing area.
3. Dependency Status
BAH rates distinguish between members with dependents and members without dependents.
The standard rate categories do not increase according to the number of dependents. They are based on whether the member has dependents under the applicable rules. DTMO's BAH guidance provides further details.
4. Local Housing Costs
Rental prices and average utilities in each Military Housing Area influence the rates. The Department of Defense reviews housing market information when establishing annual allowances.
What Is BAH Rate Protection?
Individual BAH rate protection helps prevent a service member's housing allowance from decreasing when local rates fall, provided the member's eligibility status remains unchanged.
According to the Defense Travel Management Office, rate protection generally means the member receives the rate published on January 1 or the amount received on December 31 of the previous year, whichever is higher.
Certain changes can affect rate protection, including:
- A Permanent Change of Station (PCS).
- A reduction in pay grade.
- A change in dependency status.
Members should check with their servicing finance office when their circumstances change. Read the official BAH rate protection guidance.
Where Can You Check Official BAH Rates?
The Defense Travel Management Office provides an official BAH rate lookup. You can use it to check rates by ZIP code, year, pay grade and dependency status.
Official resources:
- Defense Travel Management Office – Basic Allowance for Housing
- Military Compensation – BAH Information
- Official DoD BAH Rate Lookup
Use the official rate lookup to confirm your actual entitlement. The calculator on this page is intended for estimates and budgeting, not official payment determinations.
