What Is a Budget?

A budget is a plan for how income will be allocated to spending, saving, and debt repayment over a set period, usually a month. It compares expected income with planned expenses so that money is directed intentionally rather than spent by default.

How a Budget Works

A basic budget starts with net (take-home) income, lists fixed expenses such as rent and loan payments, then variable expenses such as food and transport, and allocates the remainder to savings and goals.

Common Budgeting Methods

Popular approaches include the 50/30/20 rule, zero-based budgeting (every unit of income is assigned a purpose), and the envelope method (fixed amounts per category).
