Zero-Based Budgeting Explained: Steps and Example

Zero-based budgeting is a way to plan where every dollar of your monthly income will go before you spend it. You assign money to expenses, savings, and debt payments until your income minus your planned allocations equals zero.

Zero does not mean you have to spend every dollar or leave your bank account empty. It means that even the money you plan to save has a specific job in your budget.

Start by listing the income you expect to receive during the month, then write down your expenses, including fixed bills such as rent and flexible costs such as groceries. Include less frequent expenses, such as car maintenance or annual subscriptions, by setting aside a manageable amount each month when possible.

Next, assign an amount to each category, including savings and any debt payments, and add the amounts together. If your allocations are more than your income, reduce some categories; if money remains, give it a purpose until the difference is zero.

Check the product’s listed specifications when evaluating how to build your budget.

Track what you spend and compare it with the amounts you planned, so you can see when a category is getting low. If one expense costs more than expected, move money from another category rather than ignoring the difference.

We suggest reviewing your budget at the end of the month and making a new plan for the next one, since income and expenses can change. If your income varies, you can start with a conservative estimate and decide how to allocate any extra money when it arrives.

Zero-based budgeting can be useful if you want a clear plan for your money or are balancing bills with savings and debt payments. Compared with a less detailed budget, it asks you to make a decision about every dollar, which can take more attention but gives you a clearer view of your priorities.
