Zero-Based Budgeting
Zero-based budgeting was originally developed in the late 1960s, and is an accounting method that has experienced a revival in recent times.
In regular budgeting, expenses from previous periods are used as a starting point and sometimes are raised by a set increment, resulting in many costs and expenses not being reviewed for years.
Conversely, zero-based budgeting does not assume increased costs are expected. Instead, it involves redrafting the budget from scratch every period by analysing and justifying all expenses.
This forces company departments to be more disciplined in their spending, and to identify inefficiencies.
While zero-based budgeting is mainly used by organisations, it can be an effective way of managing a household budget too.
What is zero-based budgeting in simple terms?
At its core, zero-based budgeting is about starting from zero and giving every single dollar a purpose. Instead of saying, I spent $500 on groceries last month, so I’ll allow $520 this month, the idea is to question every line item. Questions to ask: Do I still need this? Does this expense still provide value? Is there a better way to use this money?
In other words, nothing is taken for granted. Each expense has to justify its place in the budget whether that’s a weekly supermarket shop, gym membership, or the streaming services we subscribe to.
The process can feel like wiping the slate clean. It’s also about taking control of money rather than letting old spending habits dictate where cashflow goes.
Giving every dollar a job
One of the most important features of zero-based budgeting is the concept that every single dollar gets an assignment. Instead of money sitting unallocated in an account, you decide in advance what role it will play.
This doesn’t mean you have to spend everything. Savings, investments, and emergency funds are all jobs for your cashflow too. For example:
$1,200 might go to rent or mortgage payments
$600 to groceries and household supplies
$400 to transport and fuel
$300 to savings
$200 to entertainment and leisure
$150 to investments
$150 to an emergency fund
At the end of this process, your income minus your expenses equals zero. That doesn’t mean you have nothing left, it means that every dollar has a home and a purpose. This way, your money is working for you instead of potentially going unnoticed.
How it may benefit households
Adopting a zero-based budget for your personal finances can help to:
Review existing expenses: Old bills and subscriptions often slip through unnoticed. A zero-based budget encourages you to review them regularly
Justify new expenses: Rather than automatically saying yes to new spending, you’ll ask whether it fits into your finances
Understand your spending: Seeing exactly where your money goes each month can be beneficial
Limit impulse buying: If you’ve already allocated your dollars, there’s less room for spontaneous purchases and overspending
Achieve savings goals: By deliberately assigning money to savings, you increase your chances of reaching long-term goals
For families, it can also create transparency. Everyone knows what money is coming in, what it’s being spent on, and why. That can reduce financial stress and help avoid surprises.
Steps to create a household zero-based budget
To create a household zero-based budget:
List your income sources: income, side-jobs, rent, etc. over a set period
List all expenses for the same period; not just the essentials like housing, food, credit cards, but everything
Group expenses into categories such as: Debts; Needs; Savings; Entertainment, Travel etc
Work out the average cost for each category
Distribute your income across the categories. Aim to allocate every dollar so you’re left with zero at the end
Review your budget every quarter, or more regularly if your income varies. If one category comes up short, revisit all categories to justify each expense and adjust as necessary.
Additionally, zero-based budgeting is a handy tool for teaching young people to budget and save as they begin earning their own money. It helps them form a habit of living within their means by causing them to pause and think before spending.
The benefits of taking a more active role
Many people rely on automation when it comes to money. Direct debits, and recurring subscriptions mean that funds go without much thought. Zero-based budgeting interrupts that cycle.
By taking a more active approach to understanding expenses, you can gain:
Awareness: Small costs like takeaway lunch or app subscriptions can add up. Seeing them written down helps highlight their impact
Control: Instead of feeling like your money is controlling you, you’re in charge of where it goes
Confidence: Knowing that your bills, savings, and spending are all accounted for can reduce financial stress
Clarity: A clear plan helps you prioritise what matters most, whether that’s paying off debt, saving for a home, or building a holiday fund
For households that want to make every dollar count, the clarity gained through this budgeting method can be valuable.
The limitations of zero-based budgeting
Like any system, zero-based budgeting isn’t perfect. There are some potential drawbacks to be aware of:
Time-consuming: It can be time-consuming, especially at the beginning. Listing out every income and expense requires effort
Strict structure: Some people find the rigidity too confining. Life doesn’t always fit neatly into categories, and unexpected costs can arise
Short-term focus: Because the method looks at each budget period separately, it’s possible to lose sight of longer-term goals
Not for everyone: Some people thrive with detailed structure, while others feel restricted by it
Trial and flexibility are key
The important thing to remember is that budgeting is personal. A zero-based budget might work well for one household and feel overwhelming for another. That’s why trial and flexibility are essential.
It might take a few months to get into the rhythm of checking, justifying, and allocating. Some households choose to combine methods perhaps using a zero-based approach for certain categories like entertainment and discretionary spending, while keeping broader categories for essentials.
The goal isn’t perfection. It’s about finding a system that gives you awareness and control, while still being manageable in your daily life.
Teaching financial discipline
One overlooked advantage of zero-based budgeting is how well it teaches discipline both for individuals and families. By constantly questioning whether spending is justified, you begin to train yourself to separate needs from wants.
For children and teenagers, this is especially valuable. If they learn early on that money should always have a plan, they may carry healthier financial habits into adulthood. Even something as simple as allocating pocket money into “spend,” “save,” and “give” categories can be a good introduction to the idea.
