Gi Bill Cost of Living Allowance Calculator

The GI Bill Cost of Living Allowance (COLA) is a monthly benefit provided to veterans and service members to help offset the cost of living in different locations. This calculator helps you estimate your COLA based on your housing situation and location.

How the GI Bill Cost of Living Allowance Works

The GI Bill COLA is designed to help veterans adjust to the cost of living in different areas of the country. The allowance is calculated based on your housing situation and the location where you're living.

There are two main types of COLA:

Basic Allowance for Housing (BAH): This is the standard monthly housing allowance based on your rank and the location.
Differential Housing Allowance: This is an additional amount paid if you're living in housing that costs more than the standard BAH rate for your location.

Formula Used

The COLA is calculated using the following formula:

COLA = BAH + Differential Housing Allowance

Where:

BAH = Basic Allowance for Housing (varies by rank and location)
Differential Housing Allowance = (Cost of your housing - BAH) × 0.40 (40% of the difference)

How to Use This Calculator

To calculate your GI Bill COLA:

Select your military rank from the dropdown menu.
Enter the cost of your housing in dollars.
Select your location from the dropdown menu.
Click the "Calculate" button to see your estimated COLA.

The calculator will display your estimated Basic Allowance for Housing (BAH) and your total Cost of Living Allowance.

Key Factors Affecting Your Allowance

Several factors influence your GI Bill COLA:

Military Rank: Higher ranks receive higher BAH rates.
Location: BAH rates vary significantly by location.
Housing Cost: If your housing costs more than the BAH rate for your location, you'll receive a differential housing allowance.
Dependents: Some benefits may be adjusted based on the number of dependents.

Note

This calculator provides an estimate. For official calculations, consult the Department of Defense's BAH tables or contact your military benefits office.

Example Calculations

Let's look at two examples to illustrate how the COLA is calculated.

Example 1: Living in a Standard Housing Situation

Scenario: A Private First Class living in a standard housing situation in New York.

Rank: Private First Class
Location: New York
Housing Cost: $1,200 (matches BAH rate for this rank and location)

Calculation:

BAH = $1,200 (standard rate for this rank and location)
Differential Housing Allowance = $0 (housing cost equals BAH)
Total COLA = $1,200 + $0 = $1,200

Example 2: Living in More Expensive Housing

Scenario: A Sergeant living in more expensive housing in California.

Rank: Sergeant
Location: California
Housing Cost: $1,800

Calculation:

BAH = $1,500 (standard rate for this rank and location)
Differential Housing Allowance = ($1,800 - $1,500) × 0.40 = $140
Total COLA = $1,500 + $140 = $1,640

Comparison of COLA Examples
Factor	Example 1	Example 2
Rank	Private First Class	Sergeant
Location	New York	California
Housing Cost	$1,200	$1,800
BAH	$1,200	$1,500
Differential Allowance	$0	$140
Total COLA	$1,200	$1,640

Frequently Asked Questions

How often is the GI Bill COLA updated?

The COLA is typically updated annually based on changes in the cost of living and military pay scales. The Department of Defense reviews and adjusts BAH rates as needed.

Can I receive the GI Bill COLA if I'm not living in the U.S.?

Yes, you can receive the COLA while living abroad, but the calculation may differ based on international BAH rates and housing costs in your location.

What happens if my housing costs less than the BAH rate?

If your housing costs less than the BAH rate for your location, you won't receive a differential housing allowance. Your total COLA will be equal to the BAH rate for your rank and location.

How do I find the BAH rate for my location?

You can find official BAH rates on the Department of Defense's website or by contacting your military benefits office. The rates are updated periodically to reflect changes in the cost of living.
