The Contested Budget 1995–2031

Every federal dollar falls into one of four buckets. Only one is decided by a congressional vote each year — and it is being squeezed from both sides. Thirty-one fiscal years of outlays, same-basis, from OMB Historical Table 8.1, inflation-adjusted with CPI-U. Hover any bar for exact figures; hover the mandatory bands for the full program breakdown. FY2026 is the OMB current-services estimate; FY2027–31 are OMB baseline projections (hatched) — they assume current law, and Congress has historically spent above these baselines.

35.9% → 22.3%*
discretionary share of all outlays — the pool Congress votes on (*2031 projection)
17.9% → 8.3%*
Domestic (discretionary): education, housing, health research, transport, conservation — under 10% by 2029 on current law
15.3% → 14.7%*
net interest — nobody votes on it, and it is still climbing through the projection years

The squeeze — every year sums to 100% of federal outlays

Read the gold line. Defense (green) and non-defense domestic (steel) together are the contested pool. In the war years it peaked near 39% of everything the government spent; since the pandemic it hovers near 24–27%. The steel band — the part aimed squarely at Americans at home — fell from 17.9% to 8.3% of all spending. The mandatory buckets (sand, violet, teal, taupe, slate) ride on autopilot, and the red band (net interest) hibernated at ~5% through the low-rate era and woke up at 14.7% — by FY2025 interest took the same share of the budget as all non-defense discretionary programs combined. Beyond the dashed divider, the hatched bars are OMB's own baseline projections through FY2031 — not our opinion, their arithmetic. Inside the shrinking contested pool they split in two: defense recovers toward 14% while the domestic slice collapses to 8.3% — under 10% of everything the government spends, for the first time in the series.

The same three decades in dollars — stacked outlays, per fiscal year

Why 2025 dollars is the honest default: nominal bars flatter growth — a dollar in 1995 bought about twice what it buys today. Adjusted for inflation (CPI-U annual averages), the total pool grew ~2.3× over thirty years, not the 5.0× the raw numbers suggest. The mandatory band's rise is largely absorbed cost — healthcare price inflation in Medicaid, demographics in Social Security — not new generosity. The part of the budget that could flex toward new help is the part that is shrinking. This chart stops at FY2026 on purpose: converting OMB's projections into real dollars would mean trusting a forecast inflation rate — the share chart above carries the projection story without that extra assumption.

Defense and non-defense figures are discretionary outlays — same basis as the total, so the split is exact.
