Zero-based budgeting method: Save smarter every month

Before I discovered the Zero-based budgeting Method (ZBB), I was struggling with irregular expenses, constantly caught off guard by unexpected costs, and barely managing to save anything. Money felt chaotic, and I had no clear control over where it was going.

Because of that, I’m here to share the experience and lessons I learned from using ZBB. After just three months of applying this method, I was able to save 25% more, stop overspending, and finally feel in control of my finances.

In this guide, I’ll walk you through exactly how ZBB works, why it’s more effective than traditional budgeting methods, and how you can apply it to your personal finances, even if you’re just looking for a zero-based budgeting example or trying to improve your zero-based budgeting personal finance strategy.

1. What is the Zero-based budgeting method?

Zero-based budgeting (ZBB) is a method where every dollar of income is assigned a specific job. This could mean saving, spending, or investing. The goal is to allocate every dollar so that your budget balances out to zero. This doesn’t mean you have no money; it means every dollar has a purpose.

How it stands out from other budgeting techniques

Unlike traditional budgeting, which rolls over previous budgets or starts with rough estimates, ZBB starts from scratch each month. It forces intentionality:

• You must justify every expense, not just adjust past ones.
• No category gets funded automatically.
• It works especially well for irregular income or fluctuating expenses.

2. What you need to create a Zero-based budgeting

To get started with the zero-based budgeting method, you’ll need:

• A record of last month’s income and expenses (bank statements help).
• Budgeting tools like spreadsheets, apps (e.g., YNAB – You Need a Budget, EveryDollar), or pen and paper.
• Clear financial goals, such as debt payoff, savings, or investment targets.

3. Step-by-step guide to creating a Zero-based budget

Creating a zero-based budget is easier when broken into clear steps. Here’s a practical approach to get it done well.

Step 1: Track your earnings and costs

Before assigning any roles to your income, you need to clearly understand your cash flow. This step is about gathering, recording, and organizing your money data from the past month.

• Gather all your income sources from the past month (e.g., salary, freelance, side jobs).
• Collect all your expenses using bank statements, receipts, or budgeting apps.
• Record each transaction manually in a spreadsheet or app.
• Group expenses into categories like rent, groceries, transportation, utilities, entertainment, and subscriptions.

Zero-based budgeting example: The total income for the month is $4,000. Your expenses include $1,200 for rent, $600 for groceries, $300 for utilities, $500 for transportation, $200 for dining out, and $200 for miscellaneous items.

Step 2: Categorize spending

Before building your budget, it’s essential to understand your spending patterns. This step helps you see where your money goes and where you might cut back.

• Split your expenses into:
  • Fixed expenses: rent, insurance, loans
  • Variable expenses: groceries, dining out, gas, entertainment
• Highlight any categories with non-essential or excessive spending.
• Consider using colors or tags in your tracker for better visibility.

Step 3: Give every dollar a purpose

Now that you know your income and expenses, it’s time to allocate your money intentionally. The goal of the zero-based budgeting method is to ensure every dollar is accounted for and used with purpose.

This is where zero-based budgeting personal finance principles shine—forcing clarity and purpose into every line item.

• Take your total income for the month.
• Start assigning money to essential categories first: rent, utilities, transportation, and groceries.
• Next, allocate to savings and debt repayment.
• Assign leftover funds to discretionary categories like entertainment or a buffer.
• Keep adjusting until your total income equals total expenses—zero remains unassigned.

Example: With $4,000 income, you might allocate:

• $1,200 for Rent
• $300 for Utilities
• $500 for Transportation
• $600 for Groceries
• $800 for Debt repayment
• $300 for Savings
• $300 for Entertainment and emergency buffer

George Kamel, co-host of The Ramsey Show, shares: “Zero-based budgeting simply means your income minus your expenses should equal zero. Every pound has a job, a goal. You don’t want your pounds unemployed.” 

Step 4: Adjust and review

Your budget is a living tool. Regular check-ins help you stay on track and adapt to unexpected changes or new priorities.

• Set a weekly reminder to review your actual spending.
• Compare planned vs. actual for each category.
• If you overspend in one category, cut from another to maintain the zero-based approach.
• Update your plan for the next month based on what you’ve learned.
