What Is a Zero-Based Budget?

A zero-based budget is a budgeting method in which every unit of income is assigned a specific purpose — spending, saving, or debt repayment — until income minus all allocations equals zero. It does not mean spending everything; savings goals are allocations too.

How It Works

Start with expected monthly net income, list fixed expenses, then variable spending, savings, and extra debt payments, and adjust until the unassigned amount is zero. The plan is rebuilt each month.
