What is a budget primarily used for?

A budget is primarily used to outline expected income and expenses. It serves as a financial plan that helps individuals and organizations allocate resources effectively over a specified period, typically a month or a year. The main elements of a budget include anticipated income from various sources and expected expenditures, which can involve essential costs such as housing, food, transportation, and discretionary spending.

By providing a comprehensive view of expected financial activity, a budget allows individuals to evaluate their financial situation, prioritize spending, and set savings goals. It acts as a roadmap for managing finances, facilitating informed decision-making about where to allocate funds to ensure that all obligations can be met while also setting aside money for savings or investments.

Focusing solely on predicting future expenses, measuring savings over time, or tracking past expenses does not encompass the broader role of a budget, which integrates both income and expenses to shape future financial behavior and planning. Thus, the correct choice captures the essence of budgeting as a tool for managing all aspects of financial life.
