COLA Index

130

100 = average CONUS. An index of 130 means COLA-type goods and services cost about 30% more than in average CONUS.

The index is not your payment. Overseas COLA is paid as a percentage of spendable income (Regular Military Compensation minus housing, taxes, savings, life insurance, gifts and contributions), not of base pay. Spendable income varies by pay grade, years of service and number of dependents, so two members at the same station with the same index are paid different amounts. For the dollar figure, use the official DTMO Overseas COLA Rate Lookup.

Source: DTMO Overseas COLA index table, effective 1 Sep 2026 — 656 localities across 196 countries and territories. DTMO reissues the table on the 1st and 16th of each month, and indexes also move with exchange rates, so confirm today's figure with DTMO before relying on it.

How It Works

The Defense Travel Management Office publishes an Overseas COLA index for every OCONUS locality, and that index is what this page looks up. The scale is anchored at 100, which stands for the average cost of COLA-type goods and services in the continental United States. A locality carrying an index of 128 is one where the same groceries, fuel, car insurance and childcare run about 28 percent above that CONUS average. DTMO builds each index from local market-basket pricing and the annual Living Pattern Survey, weighted against Bureau of Labor Statistics data on how military families actually spend their money.

The index is not the payment, and that is where most COLA estimates online go wrong. Overseas COLA is paid as a percentage of spendable income, which DTMO defines as Regular Military Compensation minus housing, taxes, savings, life insurance, gifts and contributions. Spendable income moves with pay grade, years of service and number of dependents, so two members at the same base with the same index are paid different amounts. Nothing on this page multiplies your base pay by a percentage, because the allowance does not work that way. For the dollar figure, DTMO's own Overseas COLA Rate Lookup takes your grade, years of service and dependent count and returns what is actually payable.

Indexes move. DTMO reissues the whole table on the 1st and 16th of every month, exchange-rate swings can change an index as often as every pay period, and decreases are capped at 10 points and phased in at 2 points a month under the FY24 NDAA. Some duty stations carry no index at all: Okinawa, Misawa, Iwakuni, Kure, Camp Fuji, Eta Jima and Shariki all show None on the current table, which means overseas COLA is not payable there for anyone. Overseas COLA is non-taxable and sits apart from BAH and OHA, which cover housing under separate rules, while CONUS COLA is a different allowance for high-cost locations inside the continental US and is taxable.

Example: reading the index for Kaiserslautern, Germany (16 August 2026 table)

  1. 1 Input: Country or territory = Germany, Duty station = Kaiserslautern Military Community, locality code DE700. That single entry covers Ramstein, Landstuhl, Bann, Einsidlerhof, Miesau, Pirmasens and the other communities grouped with it.
  2. 2 Lookup: the 16 August 2026 DTMO table gives DE700 a COLA index of 128, in effect since 1 August 2026.
  3. 3 Read it: 128 against a base of 100 means COLA-type goods and services around Kaiserslautern cost roughly 28 percent more than the CONUS average. Germany's 64 listed localities run from 118, at Bamberg and Vilseck/Grafenwoehr, up to 154 at Munich and Pfullendorf, so Kaiserslautern sits in the lower middle of the country.
  4. 4 Compare: Okinawa (JP027) shows None instead of a number, as do Misawa, Iwakuni, Kure, Camp Fuji, Eta Jima and Shariki. No index means no overseas COLA at that duty station, whatever your grade or dependent status.
  5. 5 Result: the index on its own is not a dollar amount and not a percentage of base pay. Take your grade, years of service and dependent count to the DTMO Overseas COLA Rate Lookup for the payable figure, since the allowance is a percentage of spendable income.

Frequently Asked Questions

Who receives military COLA?
Overseas COLA goes to members assigned outside the continental US, which covers foreign duty stations plus Alaska, Hawaii, Guam, Puerto Rico and the other non-foreign OCONUS areas, wherever DTMO has published a COLA index above 100 for that locality. Where the table shows None instead of an index, as it does for Okinawa, Misawa and Iwakuni, no overseas COLA is payable at all. CONUS COLA is a separate allowance for high-cost areas inside the continental US, and neither one is housing money: BAH and OHA cover that.
Is military COLA taxable?
Overseas COLA is not taxable. CONUS COLA is taxable income included in your federal and state tax obligations. This is an important distinction because the tax-free status of overseas COLA makes it more valuable dollar for dollar.
How often is military COLA adjusted?
DTMO reissues the overseas COLA index table on the 1st and 16th of every month, so a locality's index can be revised as often as twice a month. Indexes are reviewed annually against the Living Pattern Survey and market-basket price data, and they also move with exchange rates, which can take effect as often as every pay period. Decreases are capped at 10 points and phased in at 2 points per month under the FY24 NDAA. CONUS COLA rates are set annually.
