Which of the following is NOT considered a source of revenue when calculating budget deficits?

When calculating budget deficits, one important thing to remember is that revenue comes from sources like taxes and fees that the government collects. However, any money that is borrowed is not considered revenue. This is because borrowed money has to be paid back in the future, so it doesn't truly add to the government's income for budgeting purposes. For example, if a government takes a loan to cover its expenses, that loan isn't counted as revenue; instead, it's a way to manage cash flow temporarily. Understanding this distinction helps clarify how budget deficits are calculated and why it's important to rely on actual income rather than borrowed funds.
