Term budget deficit Definition: An excess of budgetary expenditures over revenues. The federal government is well known for its inclination to operate with a budget deficit. But it is not alone. Consumers also find themselves in this position on many occasions. When a budget deficit occurs, the excess spending is financed through borrowing. For the federal government this involves issuing government securities. For households it typically involves some sort of bank loan, credit card purchase, use of savings (borrowing from thyself), or hitting a friend up for a few bucks.
