Each January, the Department of Defense sets new BAH rates for every Military Housing Area in the country. With 2026 rates now live, the next question is obvious: what happens in 2027? This forecast draws on CPI data, shelter inflation trends, housing market indicators, and economist projections to estimate where BAH rates are headed — and what it means for your next PCS budget.

How BAH rates are set

Before forecasting, it helps to understand the mechanism. DoD calculates BAH rates based on median rental costs and average utility expenses in each MHA. The target is 95% coverage of median housing costs, meaning service members absorb roughly 5% out of pocket by design.

Each year, DoD collects rental data through annual housing surveys and third-party sources like Yardi, RealPage, and local MLS databases. Rates are then published in December, effective January 1.

This is important: BAH is not a cost-of-living adjustment. It reflects local rental market conditions, not general inflation. This distinction matters because shelter costs and headline CPI have diverged significantly in recent years.

BAH increases have been substantial over the past three years after nearly a decade of stagnation:

| Year | Average BAH Increase | Notes | |------|----------------------|-------| | 2024→2025 | +5.4% | Some high-cost MHAs saw 10–15% increases | | 2025→2026 | +5.0% | Continued catch-up toward 95% coverage target | | 2015–2019 | ~0% | DoD froze rate growth for five consecutive years |

The 2025 and 2026 increases reflect both genuine rental market growth and a structural catch-up. For years, BAH lagged behind actual housing costs, leaving military families paying well above the 5% out-of-pocket design. The recent increases are partially restoring the intended 95% coverage ratio.

But 2027 will likely look different from the 5% increases of the past two years.

The data driving the forecast

CPI and shelter inflation

The Consumer Price Index tells a clear story of deceleration:

  • 2024 overall CPI-U: +2.9%
  • 2025 CPI (through April): +2.3–2.4% year-over-year
  • 2026 Fed projection: ~2.1–2.3%

Shelter CPI — the component most relevant to BAH — is cooling but still running above headline inflation:

  • 2024 shelter CPI: +4.7% (down from +5.4% in 2023)
  • 2025 shelter CPI (through April): +3.9–4.1% year-over-year
  • 2027 shelter CPI forecast: +2.5–3.0% (Moody's Analytics, CBO projections)

The critical factor here is the lag effect. Shelter CPI data lags real-time market rents by 12–18 months due to how BLS samples and processes rental data. New-lease rents have already cooled significantly in many markets, but CPI shelter data is still catching up. By 2027, this lag effect will have fully worked through the system, and shelter CPI should reflect the softer rental market we are seeing today.

Rental market data

National rent growth has decelerated sharply from the 7–10% peaks of 2022–2023:

  • Zillow Observed Rent Index (ZORI): +2.8–3.2% nationally as of early 2025
  • Sun Belt markets: Rent growth near zero or negative in some overbuilt markets (Austin, Phoenix, Nashville)
  • Coastal/supply-constrained markets: Still running at +4–5% (San Diego, Seattle, Northern Virginia)
  • Multifamily supply surge: Record apartment completions are softening rents in many Sun Belt MHAs

This geographic split matters for BAH because rates are set per MHA. A national average masks wide variation.

Home prices and construction costs

  • Case-Shiller National Home Price Index: +4.1% in 2024, cooling to ~3.8% in early 2025
  • Zillow 2027 home value forecast: +1.5–2.0% appreciation
  • Construction costs: Tariff impacts on lumber, steel, and appliances introduce upside risk

Home prices are less directly relevant to BAH than rents, but they influence the rental market through landlord cost expectations and new supply pipeline economics. If tariffs push construction costs higher, fewer new apartments get built, which tightens rental supply and supports higher rents — and higher BAH.

The 2027 BAH forecast

Based on the data, here are three scenarios for 2027 BAH rates:

Baseline: +3.0–3.5% average increase

This is the most likely outcome. Shelter CPI is trending toward 2.5–3.0% by late 2026 when DoD would be collecting the data that informs 2027 rates. Add the structural 95% coverage catch-up factor and regional variation, and a 3.0–3.5% national average increase is consistent with:

  • CBO 2027 inflation projection of ~2.2%
  • Shelter CPI forecast of +2.5–3.0%
  • Zillow rent growth normalization to ~2–3% nationally
  • Continued but diminishing coverage gap catch-up

Under this scenario, an E-5 with dependents in San Diego (2026 rate: $3,975) would see approximately $4,095–$4,115 in 2027. An E-5 at Fort Cavazos (2026 rate: $1,539) would see roughly $1,585–$1,593.

Upside: +4.5–5.5% average increase

This scenario fires if:

  • Tariff-driven construction cost inflation tightens rental supply
  • Coastal and supply-constrained MHAs see rent growth reaccelerate above 5%
  • DoD continues aggressive catch-up toward the 95% coverage target
  • Federal spending on personnel programs avoids cuts in the 2027 defense budget

The risk here is real: tariffs on construction materials and general trade policy uncertainty could push shelter costs higher than economists currently project, particularly in markets where new apartment construction already faces zoning and permitting headwinds.

Downside: +1.0–2.0% average increase

This scenario fires if:

  • US enters recession in late 2025 or 2026, dragging down rental demand
  • Defense budget cuts pressure BAH funding levels
  • Multifamily oversupply in Sun Belt markets deepens, pulling down national averages
  • DoD methodology changes slow rate growth

A recession is the primary downside risk. Moody's base case does not include a 2026–2027 recession, but their probability models assign roughly 25–30% odds. If a recession hits, rental demand drops as job growth slows, and BAH increases follow.

What this means for your PCS planning

For families comparing bases right now

If you are PCS-ing in 2026, your BAH rates are set. Use the BAH Rates tab on any DutyStation base page to look up current rates by pay grade, dependency status, and year. The 2026 rates are official DoD data.

If you are planning a PCS for mid-to-late 2027, budget conservatively. Assume the baseline +3.0–3.5% increase, but verify against local rental market trends in your destination MHA. The national average can be misleading — San Diego's increase will likely exceed Fort Cavazos's increase.

For families deciding whether to live on or off base

BAH rate trajectories matter for the rent-vs.-base-housing decision. If you expect BAH increases to slow (which our forecast suggests), locking in a rental now at a fixed lease rate may be more advantageous than in recent years when BAH was rising faster than rents. But in supply-constrained markets near major bases, the opposite could be true.

For the long view

The era of 5%+ annual BAH increases is probably ending. The catch-up that drove 2025 and 2026 rates is largely complete — DoD has restored the 95% coverage target in most MHAs. Going forward, BAH increases should track closer to actual rental market growth, which economists project at 2.5–3.5% for 2027.

This is not a pay cut in real terms, but it does mean that BAH will stop being a source of effective income growth for military families. Budget accordingly.

Methodology and sources

This forecast synthesizes data from:

  • Zillow Research: ZHVI and ZORI rental market data
  • DoD: BAH rate announcements and methodology documentation

All projections carry uncertainty. This is an informed estimate, not a DoD announcement. Official 2027 BAH rates will be published in December 2026.
