METHODOLOGY
This tool uses the term "war spending" to refer to the national defense budget function as classified by the Office of Management and Budget, which covers the Department of Defense and related military activities. Federal income tax is computed using official IRS 2025 and 2026 brackets after applying the standard deduction. The share allocated to war spending is calculated as: (national defense outlays) ÷ (individual income tax revenue), reflecting what fraction of income tax receipts would cover defense spending. FY2025: $919.2B defense ÷ $3,347B individual income tax = 27.5%. FY2026 estimate: ~$1.06T projected defense ÷ ~$3,550B income tax est. = ~29.9%, based on OBBB-authorized spending increases and CBO revenue projections. Days worked = (war spending dollars) ÷ (daily pre-tax salary, assuming 261 working days/year). This is a proportional allocation — in reality, defense is funded from all revenue sources including payroll taxes, corporate taxes, and deficit borrowing.
