What the numbers show
- This comparison is a profile test, not an assertion that GS-12 equals O-3.
- The civilian number uses Rest of U.S. locality and subtracts a new-hire FERS contribution.
- The military number uses O-3 over six, Hill AFB with dependents, and the 22% federal tax-equivalent assumption.
