How BAH Is Calculated—and Why Your Rent Does Not Matter

• Standard BAH uses 3 primary inputs: permanent duty station ZIP, pay grade, and with-dependent or without-dependent status.
• DoD targets roughly 30–75 rental units for each of 6 housing profiles within each Military Housing Area.
• Rate protection generally preserves the higher of your new January 1 rate or the amount paid on December 31.
• OHA requires DD Form 2367, while eligible Move-In Housing Allowance claims use DD Form 2556.
• Temporary BAH increases are not rate-protected when they end, and current statutory authority runs through December 31, 2026.

Your BAH comes from three inputs—not your lease

Basic Allowance for Housing is a flat monthly allowance. It does not reimburse your rent or mortgage.

For standard BAH in the continental United States, DoD normally uses three inputs:

1. Your permanent duty station ZIP code and its Military Housing Area, or MHA.
2. Your pay grade.
3. Your status as with dependents or without dependents.

Your residence ZIP normally does not control the rate. Neither does your lease amount, mortgage payment, home price, number of bedrooms, family size, or number of dependents. You generally must also be eligible for BAH and not be furnished adequate government quarters.

Use the official BAH rate lookup with the ZIP code of your permanent duty station. Do not enter the ZIP code of a cheaper suburb where you chose to live. You can also use the Military Pay and PCS Workspace to compare BAH while planning a move.

An E-5 renting a $1,200 apartment does not submit the lease and receive $1,200. The member receives the published E-5 rate for the applicable MHA and dependency category. If the allowance is higher than the rent, the member may keep the difference. If it is lower, the member pays the shortfall.

Years of service do not change BAH within the same grade. They affect basic pay, which you can check on the 2026 enlisted pay chart, but the standard BAH table uses pay grade rather than longevity.

DoD surveys six housing types in 299 MHAs

DoD builds BAH rates from the rental market near military installations. The calculation combines local median rent with average utility costs for standardized types of housing.

Rental data is collected from March through July, when PCS activity is high and more units are moving through the market. The methodology covers 299 MHAs and 1,794 annual statistical samples: six housing profiles in each MHA.

The rental information comes principally from:

• A nationwide commercial database covering more than 100,000 multifamily units.
• Installation Military Housing Office representatives.
• An independent BAH data-collection contractor.

Researchers verify that listings are available, correctly located, offered at a current rent, and priced for a standard 12-month lease. They also identify included utilities so an expense already embedded in rent is not counted twice.

The target is approximately 30 to 75 usable units for each housing profile in each MHA. The statistical goal is 95% confidence with the estimated median within 10% of the true median. If the local sample is too thin, DoD can use broader housing-cost trends or other estimation methods instead of treating a handful of listings as the entire market.

The DoD review of BAH rental data and rate setting identifies the six surveyed profiles:

• One-bedroom apartment.
• Two-bedroom apartment.
• Two-bedroom townhouse or duplex.
• Three-bedroom townhouse or duplex.
• Three-bedroom single-family dwelling.
• Four-bedroom single-family dwelling.

Specific anchor pay grades are associated with these housing profiles. Rates for grades between the anchor points are interpolated. Smoothing methods limit the effect of unusual samples, maintain sensible progression between grades, and reduce sharp year-to-year movement.

The screening rules remove housing that does not represent the market DoD is trying to measure. Mobile homes, efficiency apartments, furnished units, subsidized housing, age-restricted facilities, and seasonal rentals are excluded. Included properties must be in good repair, meet safety codes, and fall within the ZIP codes where 90% of assigned members in the MHA live.

Areas with crime exceeding twice the national average are excluded. So are neighborhoods whose civilian incomes are not comparable to regular military compensation.

Utilities include electricity, heating fuel, and water or sewer. The calculation uses the latest five years of American Community Survey data, with regional Consumer Price Index data used to adjust older observations to current-year costs.

Counties outside an MHA are assigned to one of 39 County Cost Groups based on comparable housing costs. Those groups cover fewer than 2% of BAH-eligible members.

One dependent and five dependents receive the same category

BAH has exactly two dependency categories: with dependents and without dependents.

A spouse and one child do not produce two additions. A spouse and four children do not produce five additions. Once you qualify for the with-dependent category, another dependent does not increase standard BAH.

Dependency must be formally established. For a secondary dependent such as a parent, adult child, or ward, you generally must prove that you provide more than one-half of that person’s support. Listing someone in personnel records does not automatically establish the housing entitlement.

Dual-military couples face a common trap. If neither spouse has another dependent, each member is generally treated as without dependents. If the couple shares qualifying dependents, generally one member receives the with-dependent rate while the other receives the without-dependent BAH or OHA rate. Two military spouses do not automatically receive two with-dependent allowances because they are married to each other.

Report divorce, the loss of your only dependent, a spouse entering active duty, or a custody or support change. Child-support cases can involve BAH-Diff and separate custody rules, so ordinary with-dependent guidance may not resolve the case. Have finance review the supporting documents. Do not guess from a BAH calculator.

Rate protection blocks most January BAH cuts

New BAH tables normally take effect on January 1. A lower published rate does not automatically cut the payment of every member already stationed in that area.

If you remain continuously eligible at the same location and dependency status, individual rate protection generally gives you the higher of:

• The new January 1 rate.
• The amount you received on December 31.

A local rental-market decline alone does not reduce your protected amount. Published increases flow through. Published decreases normally apply to newly arriving members or members whose protection has reset.

A promotion cannot reduce your protected monthly BAH. If the current table for your new grade shows less than your protected amount, you should not lose money solely because you were promoted. Your commissioned officer basic pay or warrant officer basic pay can change with grade and service, but those basic-pay tables do not override BAH protection.

Protection attaches to your eligibility at the location and status. It does not attach to a lease, landlord, or house. Moving to another apartment within the same MHA does not by itself establish a fresh BAH rate.

Events that can end or reset protection include:

• A PCS or the end of your eligibility in the current MHA or County Cost Group.
• A reduction in pay grade.
• A change in dependency status.
• A loss or interruption of BAH authority.
• For a Reserve Component member, a break in active service of one or more calendar days.

Your protected rate does not travel to a new duty station. After a PCS, finance generally establishes BAH using the new permanent duty station and your current grade and dependency category.

Temporary BAH increases authorized for a disaster or personnel surge follow a different rule. They do not receive normal rate protection when the temporary increase ends. The current statutory authority for temporary increases runs through December 31, 2026, but a particular location must still receive an authorized increase.

OHA reimburses documented overseas housing costs

BAH primarily applies to permanent duty in the 50 states. Overseas Housing Allowance applies at qualifying overseas locations when government housing is not provided. Treating the two systems as interchangeable can create an overpayment.

OHA includes a rental allowance, a utility and recurring-maintenance allowance, and Move-In Housing Allowance where authorized. For a member with dependents, the rental allowance is the lesser of actual reported rent or the applicable ceiling. For a member without dependents, it is the lesser of actual reported rent or 90% of the applicable maximum.

OHA must be recomputed when rent changes. A claim for eligible Move-In Housing Allowance expenses uses DD Form 2556, with receipts or other support required for reimbursable categories. MIHA normally covers one dwelling during a permanent-duty tour unless a government-funded local move leads to another OHA-covered dwelling.

The DoD housing-allowance rules in Volume 7A, Chapter 26 govern BAH protection, OHA reimbursement, and the required forms.

An unaccompanied overseas tour requires a finance review. Depending on dependent location, government quarters, command sponsorship, and other facts, you may have an entitlement involving BAH for dependents and Family Separation Housing–OHA for private overseas housing. Do not describe it on paperwork as ordinary concurrent BAH and OHA without confirmation from servicing finance.

You can legally keep the difference under BAH

You may choose housing that costs less than your BAH and keep or use the difference. DoD does not reduce ordinary BAH because you found a less expensive apartment.

Legal ways to lower your housing cost include:

• Renting below your monthly BAH.
• Sharing a house or apartment where the lease, local law, and command rules allow it.
• Choosing a smaller or less expensive unit.
• Applying BAH toward a mortgage payment below the allowance.

BAH is generally not treated as taxable pay. You can use the difference for emergency savings, debt reduction, utilities, or other household costs.

You also carry the downside. If rent, insurance, commuting costs, or repairs exceed your allowance, DoD does not reimburse the ordinary shortfall.

Buying a home does not change how standard BAH is calculated. The system still follows the local rental market. Your purchase price, mortgage principal, interest rate, property taxes, homeowners association fees, and repair bills do not set your rate.

Privatized or government housing can work differently because your housing arrangement may direct all or part of your BAH to the housing provider. A BAH entry on your leave and earnings statement does not necessarily mean you have unrestricted off-base BAH to keep.

Overseas reimbursement has a harder boundary. You cannot inflate an OHA lease, hide a roommate’s contribution, create a side agreement with a landlord, or report rent you do not actually pay to capture the ceiling. False information about duty location, dependents, custody, support, rent, a lease, or ownership can create debt and disciplinary exposure.

Verify six items before signing a lease

A BAH estimate does not establish your entitlement. Your orders and personnel records do.

1. Confirm the permanent duty station ZIP on your orders.
2. Look up the correct calendar year, pay grade, and dependency category.
3. Check whether government or privatized housing changes how the allowance is handled.
4. Ask finance whether you have a protected prior rate after an annual table decrease.
5. Report a dependency, custody, grade, or duty-location change promptly.
6. For an overseas lease, obtain approval and complete DD Form 2367 before assuming OHA will cover the amount.

Build your housing budget from the rate finance says you are entitled to. Then account for rent, utilities, insurance, commuting, deposits, and repairs. Sign only after the numbers work without assuming BAH will match the bill.

Questions people actually ask

Is BAH based on where I live or where I am stationed?

BAH is normally based on the ZIP code of your permanent duty station and its Military Housing Area, not the ZIP code where you choose to live. Living farther away in a cheaper or more expensive area usually does not change the rate. Exceptions can apply in specialized assignments or dependent-location cases, so use your orders and ask finance if your situation is unusual.

Does the military see my lease when calculating BAH?

Your actual lease does not set ordinary CONUS BAH. The published rate comes from your duty location, pay grade, and with-dependent or without-dependent status. Finance may request documents to verify eligibility or resolve a case, but your monthly rent does not become your individual BAH amount. OHA is different because overseas rental costs require documentation.

Do I receive more BAH for each child?

No. Standard BAH has only two locality categories: with dependents and without dependents. Once you qualify for the with-dependent rate, a second or later child does not add another payment. Dual-military couples generally cannot both claim the same shared dependent for the with-dependent rate. Secondary dependents also require a formal dependency determination.

Can my BAH decrease when I get promoted?

A promotion cannot reduce an otherwise protected BAH payment. If you remain eligible at the same location and status, you should not receive less solely because the current table for your new grade is below your protected amount. A PCS, reduction in grade, dependency-status change, or interruption of entitlement can reset protection, so review the change with finance.

Can I legally keep BAH left after paying rent?

Yes. Ordinary BAH is a flat allowance, so you may rent below the rate and keep the legitimate difference. You may also share lawful housing or apply BAH toward a mortgage. OHA does not work this way: its rental component is limited to documented cost and the applicable ceiling. False leases, hidden contributions, or inflated rent are not legitimate savings strategies.
