How CONUS COLA is calculated
DTMO compares non-housing prices in each Military Housing Area (groceries, transportation, services, taxes) with the average stateside location. An area qualifies when that index is above 107, and every point above it is one point of COLA. San Francisco at 8 points in 2026 means its costs run about 15% above average.
Each point is worth a fixed dollar amount per month that depends on your grade, years of service and whether you have dependents. For 2026 it runs from $31 (junior enlisted, no dependents) to $73 (senior officers with dependents). Your monthly COLA is simply that amount times the area's points.
Things that change the number
The table resets every January 1, and areas drop in and out: DTMO paid 26 areas in 2022, 7 in 2023 and 18 in 2026. Moving to a ZIP outside a paid area ends it the day you report, with no phase-out. Unlike BAH and overseas COLA, CONUS COLA is taxable, so the take-home is smaller than the figure above.
Where the numbers come from
DTMO's CONUS COLA ASCII files for 2016 through 2026, including the April 2024 and April 2025 revisions: the ZIP list with each area's points, and the with- and without-dependents rate tables. Policy is in DoD FMR Volume 7A, Chapter 67. Check any result against DTMO's CONUS COLA rate lookup.
