Which financial document helps individuals track spending and saving?

A budget is a financial document specifically designed to help individuals plan and track their spending and saving. It provides a structured approach to managing finances by outlining expected income and categorizing expenses, allowing individuals to set spending limits in different areas. By regularly monitoring a budget, individuals can adjust their spending habits, make informed financial decisions, and work toward their savings goals.

In comparison, an income statement typically summarizes revenue and expenses over a specific period, but does not provide the same level of detail for tracking ongoing spending and saving habits. A net worth statement focuses on an individual's overall financial position by listing assets and liabilities, giving a snapshot of wealth at a given time rather than tracking transactions. An investment portfolio refers to a collection of investments, which shows performance but does not help with day-to-day budgeting or saving strategies. Therefore, the budget stands out as the most effective tool for monitoring and managing finances on a regular basis.
