Every BAH question about rank is really a question about one structure: 27 pay grades in three families, each carrying exactly two rates — with dependents and without. This guide lays the whole ladder out on one real housing area (San Diego, 2026), explains why the rungs are spaced the way they are, works the E-5 row that students and junior enlisted ask about most, and then handles the two situations that bend the ladder: dual-military couples, and dependents who draw on the same rate through the GI Bill.

The three families on the ladder

The ladder’s shape comes from DTMO’s housing profiles. Each pay grade is anchored to the housing a civilian of comparable income in that market typically rents: a one-bedroom apartment for the junior enlisted rungs, two-bedroom apartments and townhouses through the middle, and three- and four-bedroom houses at the senior end. Three families climb it together — enlisted (E-1 to E-9), warrant officers (W-1 to W-5) and commissioned officers (O-1 to O-10). Officers who were prior-enlisted get their own rungs — O-1E, O-2E, O-3E — paid slightly above the straight O-1 to O-3 rates. Two structural quirks follow from the anchoring: the bottom rungs are flat (in San Diego, E-1 through E-4 share one rate, because they share one housing profile), and the top rungs merge (O-7 to O-10 share one rate — the table stops differentiating above a certain standard of house).

One complete ladder: San Diego, 2026

Source: DTMO “All BAH Rates” 2026, Military Housing Area CA038 (San Diego, CA), monthly rates effective January 1, 2026. Every housing area publishes the same ladder with its own figures.

Read the dependency step column carefully, because it breaks the obvious assumption. The step is not a fixed family allowance — it is the difference between two anchor profiles, so it widens and narrows as the ladder climbs: $903 at E-1, $1,017 at E-6, then down to $270 at O-3, where the without-dependents profile already sits close to the family one. Nothing about your actual family size enters any of it. One dependent or five, the with-dependents rate is the same number.

The E-5 row, because everyone asks

E-5 is the most-searched rung on the ladder — it is the first grade at which many members move off base, and it is the grade the VA uses for student housing. The e5 bah figures for 2026 make the locality point better than any explanation: an E-5 with dependents draws $3,975 a month in San Diego, $5,127 in San Francisco, $3,132 in the Washington DC metro area, $2,358 in Colorado Springs and $1,806 at Fort Bragg. The e5 with dependents bah rate is never a national number; it is a ZIP code wearing a rank. (The E-5 without-dependents rate in the same areas runs from $1,527 at Fort Bragg to $3,147 in San Diego.) If you take one habit from this guide, make it this: never quote a BAH figure without its housing area and year attached.

Dual military: two allowances, one dependency claim

When two service members are married to each other, the instinct that the household gets “one BAH” is wrong — each member draws their own allowance at their own grade and duty station. The FMR’s restriction is narrower and more specific: for their shared children, only one of them may be paid at the with-dependents rate. The couple chooses which one claims the children; if they cannot agree, the with-dependents rate goes to the senior member; and the election can be transferred later, effective from the new election date. So dual military bah with dependents in practice looks like this, on San Diego’s 2026 table: two E-6s with children draw $4,404 (with dependents) + $3,387 (without) = $7,791 a month between them. Without children, the same couple draws two without-dependents rates: $6,774. Children from a previous relationship follow the same logic — one member claims the with-dependents rate on the children collectively, the other is paid without.

Dependents on the other side of the table: Chapter 33

Dependents meet this ladder from a second direction. Under VA Chapter 33 benefits for dependents — transferred Post-9/11 GI Bill entitlement — a spouse or child attending school can draw the Monthly Housing Allowance, which is this ladder’s E-5 with-dependents rate for the campus area, prorated by tier and course load exactly as a veteran student’s is. The one exclusion is precise: a spouse using transferred benefits while the service member is still on active duty receives no MHA, because that household is already being paid BAH itself. A child using transferred benefits is not under that exclusion. It is the same design principle as the dual-military rule, one program over: the government pays the family housing rate once per household circumstance, and the various rules exist to stop it being paid twice for the same roof.

The anchor profile behind each rung

DTMO publishes the housing standard each rung is priced against — the profile the survey goes shopping for in every area:

Anchor standards per DTMO’s BAH rate-setting documentation. Intermediate grades (warrants, mid officers) sit on profiles between these steps.

This is why the rungs are unevenly spaced: a step that changes the type of home — apartment to townhouse at E-6, townhouse to house at E-9 — moves the rate far more than a step within one type. It is also why the with/without gap behaves oddly at the top: once both profiles are houses in the same neighbourhoods, having dependents changes the target home very little.

The promotion step, priced

Promotion re-prices you onto a new rung at your existing area, effective the date of rank. On San Diego’s table the E-5 to E-6 step is worth $429 a month with dependents ($3,975 → $4,404) and $240 without — on top of the base-pay rise. Rate protection has a say here too: promotion is one of the events that ends protection, because your entitlement is recomputed at the new grade. The same event in reverse — a reduction in grade — also ends protection and re-prices you downward onto the lower rung’s current rate. Members weighing a move, a promotion board and a lease renewal in the same quarter should run all three dates through the table: the ladder pays the rung you hold, in the area you are assigned to, on the day in question, and each of the three can change the answer independently.

The prior-enlisted rungs, and reading the step for your household

The O-1E, O-2E and O-3E rungs exist because a prior-enlisted officer’s civilian income counterpart is not a 22-year-old graduate: the table prices their housing standard a step above the direct-commission rung of the same grade — in San Diego, O-3E draws $4,770 with dependents against O-3’s $4,518. The steps stop at O-3E because beyond that point the service requirement behind the “E” designation can no longer distinguish the profiles. For a household deciding where it can afford to live, the practical reading of the ladder is the step column, not the rung: your budget changes by the dependency step when a first dependent arrives ($828 at E-5 in San Diego) and by the grade step when a promotion lands — and by nothing at all when a second child does. Families who plan on the step column are never surprised by a BAH figure; families who plan on averages usually are, once, in their first expensive area.

Checking your own rung

The ladder in your area has the same shape and different numbers. To read your own row — your grade, both dependency rates, and the step between them — run your duty ZIP through the BAH calculator: it reads the same official DTMO 2026 table this guide’s ladder was taken from, and it shows your grade against its neighbours so you can see the rung above and below yours as well.
