Open evidence / Fixed profiles / Explicit assumptions

Follow the compensation evidence.

Start with the selected GS-15 and O-3 comparison, then inspect the historical explorer, formulas, and original data. The valuation basis matters: recurring cash, tax-equivalent value, and selected deductions answer different questions.

The same profiles. Three ways to compare.

Rest of U.S. GS-15 step 1 and an O-3 over six years at Hill AFB, with dependents. These are fixed compensation profiles; their duties and service obligations differ.

Annual comparison values in dollars. F indicates a 2027 projection.
Year	Basis	Captain	GS-15
2026	Cash	$125,118	$147,945
2026	Tax-equivalent	$134,221	$147,945
2026	Selected deductions	$128,464	$132,263
2027F	Cash	$130,688	$147,945
2027F	Tax-equivalent	$139,791	$147,945
2027F	Selected deductions	$133,690	$132,263

Read the basis before the result.Tax-equivalent value includes a modeled 22% gross-up on military allowances. The selected-deduction basis also deducts Social Security and a 4.4% civilian FERS contribution. It is not take-home pay or a complete benefits valuation. The 2027 projection holds 2026 BAH and BAS flat.
