2026 BAH Calculator — Housing Allowance Estimator by Rank and Location

Basic Allowance for Housing (BAH) is the tax-free monthly payment that covers the cost of off-base housing for service members. It is one of the largest components of military compensation — for many enlisted families, BAH actually exceeds basic pay. Use the calculator below to estimate your 2026 BAH by rank, dependent status, and location tier.

How BAH Works in 2026

BAH is paid monthly to service members who do not live in government quarters. The amount varies based on three factors: pay grade, dependent status, and the Military Housing Area (MHA) you are stationed in. Rates are recalculated each year and went up an average of 4.2% for 2026.

The Department of Defense surveys median rental costs in roughly 300 MHAs nationwide. Each MHA has its own rate table covering all pay grades — meaning an E-5 with dependents in San Diego receives substantially more BAH than the same E-5 stationed at Fort Sill, Oklahoma, even though their basic pay is identical.

BAH Is Tax-Free

This is the part most service members underrate. BAH is not taxed at the federal or state level. For someone in the 22% bracket, $2,000 of BAH is the equivalent of roughly $2,564 of taxable salary. Over a 20-year career in a high-cost area, the tax-free nature of BAH is worth tens of thousands of dollars compared to civilian compensation.

With vs. Without Dependents

Service members with at least one dependent (spouse or child) receive a higher BAH rate at the same pay grade. The gap typically runs 12–25% depending on rank — narrower at junior enlisted grades, wider at senior officer grades. If you are dual-military, only one spouse can claim the with-dependent rate.

Rate Protection

If BAH rates drop in your area year over year, service members already living there are “rate-protected” — your BAH does not decrease while you remain at that duty station. New arrivals get the lower current rate. This is one reason long-tenured residents at a base sometimes draw noticeably more BAH than peers who arrived later.

Calculator Limitations

The estimator above uses national-average 2026 rates with a location-tier multiplier. It is meant for planning and rough comparisons — not for filing or official paperwork. For exact rates tied to your duty ZIP code, always use the official DTMO BAH Calculator.
