How high will federal debt and interest costs rise by 2035?
Core argument: CBO projects debt held by the public will rise from nearly $29 trillion, roughly 98% of GDP, to $52 trillion, or 118% of GDP, by 2035, with deficits totaling $22 trillion (5.8% of GDP) over the decade.
Debt held by the public will rise from nearly $29 trillion today, or roughly 98% of GDP, to $52 trillion by 2035, or 118% of GDP. Deficits will total $22 trillion (5.8% of GDP) over the next decade. Spending will grow from 23.3% of GDP in 2025 to 24% by 2035, while revenue will grow from 17.1% of GDP in 2025 to 18.3% by 2035 under current law, which assumes the expiration of the 2017 tax cuts at the end of this year. Interest costs will match their record as a share of GDP in 2025 – 3.2%– and rise to 4.1% of GDP by FY 2035. The economy will continue growing at a steady clip, with real GDP growth averaging 1.8% over the decade, unemployment and inflation normalizing around 4.4% and 2%, respectively, and 10-year Treasury notes averaging 3.8% by the end of the decade.
