Budget Deficit

A budget deficit occurs when government spending exceeds its tax revenue in a given year.

Governments finance deficits by borrowing, which adds to the national debt. Deficits can stimulate a weak economy but may raise interest rates and crowd out private investment. They typically grow during recessions.

Formula / Example

Budget deficit = Government spending − Tax revenue (when positive).
