What is OCONUS COLA?

Overseas COLA compensates service members stationed at OCONUS locations where the cost of living exceeds the average CONUS. Unlike CONUS COLA, OCONUS COLA is non-taxable.

Rates are calculated based on your location, rank, years of service, dependency status, and current exchange rates. Because exchange rates fluctuate, your COLA can change every pay period.

How OCONUS COLA is calculated

1

Step 1 — Spendable income

DTMO determines your "spendable income" based on rank, YOS, and dependents. This is the portion of pay expected to go toward daily living (food, goods, services — not housing or savings).

2

Step 2 — Cost comparison

DTMO surveys overseas living costs, comparing prices at your location against average CONUS prices. This produces a COLA index.

3

Step 3 — Exchange rate adjustment

The COLA index is adjusted based on current USD/local currency exchange rates. This is why your COLA changes each pay period.

4

Step 4 — Your COLA amount

Spendable income × adjusted COLA index = your monthly COLA.

Common questions

When does OCONUS COLA start? Begins when you report to your OCONUS duty station. May take 1–2 pay periods to appear on your LES after your gaining finance office processes your arrival.

Can my COLA go down? Yes. If the USD strengthens against local currency, your COLA decreases — even if local prices haven't changed. Can happen pay period to pay period.

Do I receive COLA during leave? Yes, as long as you're stationed OCONUS. COLA continues during leave, TDY, and R&R as long as your PDS remains OCONUS.

What about dependents? Your COLA rate accounts for dependents. If dependents are command-sponsored at your OCONUS location, COLA is "with deps." If they remain in CONUS, you get the "without deps" rate.

About this entitlement

What you need to know — straight from the regulation

What Overseas (OCONUS) COLA is

Overseas Cost-of-Living Allowance (OCONUS COLA) is a non-taxable supplemental payment made to service members assigned to permanent duty stations outside the contiguous United States (including Alaska, Hawaii, U.S. territories, and foreign countries) where the local cost of goods and services exceeds what the member would pay in CONUS.

OCONUS COLA is authorized under 37 U.S.C. § 405 and administered under the DoD Financial Management Regulation (FMR), Volume 7A, Chapter 68. Rates are published and updated frequently by the Defense Travel Management Office (DTMO) based on foreign-currency exchange rates and local retail price indexes, so the allowance changes through the year — sometimes each pay period.

How it is computed

OCONUS COLA is computed as a location-specific index applied to the member's "spendable income" — a portion of pay defined in DoD FMR Vol. 7A that varies with grade, years of service, and dependency status. The index reflects costs for goods and services at the OCONUS location versus the CONUS baseline; the exchange-rate component is updated continuously.

DoD FMR Vol. 7A, Chapter 68

Tax treatment

OCONUS COLA is non-taxable. It is not included as wages on the W-2 and no federal, FICA, or state income tax is withheld from the allowance. This is the opposite of CONUS COLA, which is taxable.
