What is CONUS COLA?
CONUS COLA (Continental United States Cost of Living Allowance) is a supplemental allowance paid to military members stationed in high-cost areas within the 48 contiguous states. While BAH covers housing costs, CONUS COLA addresses the higher costs of goods and services like groceries, transportation, childcare, and utilities. For 2026, approximately 127,000 service members across 18 designated areas receive CONUS COLA payments totaling roughly $99 million annually.
Unlike OCONUS COLA paid overseas, CONUS COLA is a taxable allowance β it appears on your W-2 and is subject to federal and state income taxes. Despite this, it represents meaningful additional compensation: an E-5 with dependents stationed in San Francisco receives $384/month ($4,608/year) in CONUS COLA on top of their base pay and BAH.
How CONUS COLA is Calculated
CONUS COLA uses a formula based on three factors: your pay grade base rate (which varies by rank and years of service), a location index (1-8, reflecting how expensive the area is), and your dependency status. The formula is simple: Monthly COLA = Base Rate Γ Location Index. San Francisco has the highest index at 8, while most eligible areas share the lowest index of 1.
Rates are set once per year and take effect January 1st. Unlike OCONUS COLA which fluctuates with exchange rates, CONUS COLA is stable throughout the calendar year. The Department of Defense reviews eligible areas annually based on cost-of-living surveys, and areas can gain or lose eligibility from year to year β in 2026, 9 areas lost eligibility while 6 new areas were added.
CONUS COLA vs BAH vs OCONUS COLA
These three allowances serve different purposes. BAH (Basic Allowance for Housing) covers rent and housing costs and is tax-free. CONUS COLA covers non-housing expenses in high-cost CONUS areas and is taxable. OCONUS COLA covers non-housing expenses overseas and is tax-free. A service member in San Francisco receives all three: BAH for their housing costs, plus CONUS COLA for the elevated cost of everything else. Understanding how these stack together is key to evaluating your total compensation at different duty stations.
Eligible Locations for 2026

Frequently Asked Questions
Do I need to apply for CONUS COLA?
No. CONUS COLA is automatically calculated based on your duty station ZIP code. If your duty station is in an eligible area, the allowance appears on your LES (Leave and Earnings Statement) without any action on your part.
Is CONUS COLA taxed?
Yes. Unlike BAH and OCONUS COLA, CONUS COLA is subject to federal and state income tax. It is included in your gross taxable income on your W-2. Depending on your tax bracket, you'll keep roughly 75-85% of the CONUS COLA amount after taxes.
What if I live off-base in a nearby area?
CONUS COLA is based on your duty station ZIP code, not where you live. If your installation is in an eligible ZIP code, you receive CONUS COLA even if your off-base residence is in a non-eligible ZIP code.
Can I receive both CONUS COLA and BAH?
Yes. BAH and CONUS COLA are separate entitlements. BAH offsets housing costs while CONUS COLA offsets non-housing costs. Receiving one does not reduce or eliminate the other. Service members in high-cost CONUS areas benefit from both.
How does CONUS COLA compare to OCONUS COLA?
CONUS COLA is taxable and changes once per year. OCONUS COLA is tax-free and can change as often as every two weeks due to exchange rate fluctuations. OCONUS COLA rates are generally higher because overseas costs can be substantially more than stateside. You cannot receive both simultaneously β you get whichever applies to your current duty station.
