From the Committee for a Responsible Federal Budget:
The United States entered the current public health and economic crisis facing high levels of debt and trillion-dollar deficits. Due to the effects of the crisis and legislation enacted to combat it, debt and deficits will now grow much higher, to never-before-seen levels both in dollars and as a share of Gross Domestic Product (GDP). Our latest projections find that under current law, budget deficits will total more than $3.8 trillion (18.7 percent of GDP) this year and $2.1 trillion (9.7 percent of GDP) in 2021. We project debt held by the public will exceed the size of the economy by the end of Fiscal Year 2020 and eclipse the prior record set after World War II by 2023. These projections almost certainly underestimate deficits, since they assume no further legislation is enacted to address the crisis and that policymakers stick to current law when it comes to other tax and spending policies. The projections also assume the economy experiences a strong recovery in 2021 and fully returns to its pre-crisis trajectory by 2025. Assuming a slower and weaker recovery (but no changes in law), we estimate debt would grow to 117 percent of GDP by 2025.
