What is 'zero-based' budgeting?

Zero-based budgeting (ZBB) is a way of managing your money where every pound of income is assigned to a specific expense, leaving nothing unaccounted for. By giving each pound a purpose, you make sure your money is actively working toward your financial goals.

Originally used by businesses to manage their finances more efficiently, zero-based budgeting has become popular for personal finance too. The method forces you to regularly review and reassess your spending habits, promoting better financial discipline.

In this expert guide, we’ll walk you through how zero-based budgeting works and how it can give you greater confidence and clarity when managing your finances

Let’s say you earn £2,500 a month. Zero-based budgeting would have you assign every penny to different categories, ensuring nothing is left over and every pound has a stated purpose.

Once you’ve paid for the essentials, you can allocate your remaining money to anything you want. Realistically, you might adjust your zero-based budget monthly depending on financial changes. For example, if you complete your repayments on a loan, you could then allocate that money to your savings or another category.

• Promotes discipline: A zero-based budget forces you to track every pound, preventing unnecessary or impulse spending.
• Financial clarity: You know exactly where every pound goes, which helps manage cash flow and prepare for future expenses.
• Improves habits: Allocating funds to categories like debt repayments and savings as a part of your budget makes them a priority rather than an afterthought.

• Time-consuming to set up: The initial process of listing and categorising all income and expenses can take effort, especially for someone who isn’t used to managing their budget so closely.
• Requires ongoing tracking: You’ll need to regularly monitor and update your budget as your financial situation changes.
• Challenging with a variable income: If you have irregular earnings, like in freelance or commission-based jobs, sticking to zero-based budgeting can be challenging without adjustments each month.

Setting up a zero-based budget is simple but requires discipline and planning. Here’s how to begin.

1. List out your income: List all sources of monthly income, including your main salary and any additional streams, to know exactly what you’re working with.
2. Track your typical expenses: Include essential expenses, like rent, utilities, groceries and minimum debt repayments, as well as savings and discretionary spending.
3. Allocate into categories: Assign your income to a specific expense category, ensuring no money is left behind.
4. Keep an emergency fund: This way, you won’t throw your finances off course if you accidentally overspend in one category.
5. Review regularly: Adjust your budget throughout the month based on any unexpected changes, ensuring you stay on track.
