Code of Federal Regulations Title 5. Administrative Personnel § 5.591.226 How does OPM apply the CPIs?

Current as of January 02, 2025 | Updated by Findlaw Staff

(a) OPM uses a three-step process to adjust price indexes by relative annual or biennial changes in the CPIs. For steps 1 and 2, OPM computes the annual change by dividing the CPI from 1 year after the survey by the CPI from the time of the survey. OPM computes the biennial change by dividing the CPI from 2 years after the survey by the CPI from the time of the survey.

(1) Step 1. OPM computes the annual or biennial CPI change for the COLA area.

(2) Step 2. OPM computes the annual or biennial CPI change for the DC area.

(3) Step 3. OPM multiplies the COLA area price index from the last survey by the COLA area CPI change computed in step 1 divided by the DC area CPI change computed in step 2. The adjusted price index is rounded to the second decimal place.

(b) Example:

Computation:

117.33 x (174.7/172.2)/(161.9/159.7) = 117.4159, which would round to 117.42.
