2027 Military Retirement COLA: Will it Match Projections?

Key Points:

• Recent projections place the 2027 COLA between 3.6% and 3.8%.
• Inflation readings in July, August and September determine the official COLA, and economic conditions during those months can affect the final outcome.
• The military retiree, Social Security, and VA disability COLA is based on changes in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), a different inflation measure than typically seen in headlines.
• The 2027 COLA takes effect on Dec. 1, 2026.

Projections for the 2027 cost-of-living adjustment (COLA) are starting to appear in news reports. The annual COLA is a topic of interest for military retirees, as well as Social Security and VA disability compensation recipients, because it typically increases their monthly benefits.

What is the projected 2027 military retiree COLA?

Recent projections generally place the 2027 COLA in the range of 3.6% to 3.8%. Forecasts are determined using inflation data available so far in 2026 and expectations for the coming months. But they won’t necessarily match the final COLA, which will be based on inflation data gleaned from third quarter consumer prices. So, retirees should view current forecasts as estimates rather than guarantees. 

How is the military retirement COLA calculated?

The inflation-based COLA helps military retirees maintain the purchasing power of their pension over time. When prices rise, the COLA helps offset the increase.

Inflation is tracked with the Consumer Price Index (CPI), which measures changes in prices that consumers pay for goods and services. The version of CPI that’s most often in headlines is the Consumer Price Index for All Urban Consumers, or CPI-U. But a different version, the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) is used to calculate the COLA. It reflects spending patterns of a narrower group – wage-earning households. In CPI-W, certain spending categories, such as transportation and food, receive greater weight.¹ This helps explain why inflation reported in the news may differ from the inflation measure used to determine your COLA.

The COLA calculation itself is straightforward. The average CPI-W reading for July, August and September is compared with the average for the same three-month period a year earlier. The percentage increase becomes the next year's COLA. If the percentage decreases, the COLA will be zero.²  

What might cause the 2027 COLA to differ from projections?

Since the COLA is tied specifically to third-quarter inflation, the amount can change if inflation deviates from current forecasts. If inflation runs higher than projected, the final COLA could be higher than current estimates. If inflation moderates, the COLA could be lower. Multiple economic factors can play a role. Examples might include movement in fuel prices, consumer spending, and wages.

What’s important to keep in mind, though, is that a larger COLA is not necessarily a financial gain. It may seem like good news, but it generally reflects higher prices for goods and services. So, a bigger COLA may simply mean you’re also paying more for gas, groceries, or other expenses.

How does the projected 2027 COLA compare to previous years?

If recent estimates hold, an upper-3% COLA in 2027 will be about 1 percentage point higher than the 2026 COLA of 2.8%. Both are substantially less, though, than the higher-inflation, post-pandemic years, such as 2023’s 8.7% COLA. When October arrives and all third-quarter inflation data is collected, we’ll know where the next COLA falls relative to prior years.

Are military retirement COLAs and active-duty pay raises equivalent?

Both the retiree COLA and the annual active-duty pay raise typically result in an increase in pay, but they are not the same. The COLA is tied to CPI and the pay raise is benchmarked to the Employment Cost Index (ECI), which tracks private-sector wage growth. Because the two are based on different indices, the resulting percentages usually differ from year to year.

Active-duty service members are expected to receive a pay raise in 2027. The amount is not determined yet and is currently going through the legislative process. For details on next year’s potential pay raise, see our article on the 2027 military pay raise. 

Preparing for your 2027 COLA

An announcement about the official 2027 military retiree COLA is expected in October after all third-quarter inflation data has been reported. The adjustment will take effect Dec. 1, 2026, and retirees should see the increase reflected in payments beginning Dec. 31, 2026.

Whether the official COLA lands near recent projections or falls outside the forecasted range, its impending arrival can serve as a reminder that your military retirement pay is just one part of your broader financial picture.
