Zero-based budgeting in Australia

Your pay can look like enough for the month until you remember the insurance renewal, a weekend away and everything still coming out before payday. Zero-based budgeting gives that money specific jobs before you spend it, so you can see what you've already promised it to. I'll count one month's pay down to $0, then show what happens when a repair breaks the plan. There's a printable sheet at the end.

What is zero-based budgeting?

Zero-based budgeting means giving all the money you're planning with a job until there's $0 left to assign. Rent gets a share, and so does money you're keeping for later. You decide the amounts, with no compulsory percentages.

The zero belongs to the plan. You might have $1,200 in the bank and still have $0 left to assign, because that money is already set aside for insurance, savings or next month. I find that zero reassuring: it tells me the money I'm keeping has been considered too.

I like this method for people who feel better knowing exactly what their money is for. Monthly pay gives it a natural rhythm: decide what this pay needs to cover until the next one. The trade-off is upkeep, because you'll need to check spending against those jobs and change the amounts when life changes. Some people find that calming, while others find it another thing to keep up with.

A zero-based budgeting example: one month's pay

Say $5,000 lands in your account this month, after tax and anything else your employer takes out. It has to last until your next pay.

Start with what has to be paid before the next payday, then set aside money for later bills. Give yourself an amount you can actually live on for everyday choices, and decide what the remaining money should do. If you haven't worked out your costs yet, the guide to making a budget helps you build that list from your own statements.

The figure below assigns $2,350 to housing and bills, $550 to groceries, $350 to transport and health, $400 to annual costs and $550 to everyday spending. It then sets aside $400 for emergency savings (money for urgent surprises), $250 for a holiday and $150 of breathing room for small changes during the month. Subtracting each amount from the $5,000 leaves $0 without a job.

7. HolidayAssigned $250, left to assign $150Step 7 of 8.
8. Breathing roomAssigned $150, left to assign $0Step 8 of 8.

You can deliberately keep money flexible, as long as you know what that flexibility is for.

If the month goes exactly to plan, the figure's “Spent this month” total is $3,800 for housing and bills, groceries, transport and health, and everyday spending. “Kept for later” is the other $1,200 for annual costs, emergency savings, the holiday and breathing room. You'd still have $0 left to assign.

Once you know what each amount is for, keep that plan beside your account balance when deciding what to spend.

The jobs people forget

Costs that don't come every month

Car registration, insurance renewals and Christmas still need money in the months when they aren't due. The example puts $400 a month into annual costs. Split that into your actual bills and check their due dates.

If a bill is due sooner, each pay has to carry more. Subtract what's saved already, then divide the remaining bill by the paydays before it's due. Money held for those bills keeps its job when the month ends.

Keep money for small changes

The example's $150 of breathing room covers small changes within the month. It's separate from the $400 going into emergency savings, which you're building for a bigger interruption. Our emergency fund guide goes into what that reserve is for.

If the breathing room keeps going on the same thing, such as prescriptions, give that thing its own amount next month.

Pay that hasn't arrived

You can sketch next month's budget in advance, but only money you have can fund today's jobs. An expected extra shift stays out of the available amount until you're paid. If your pay changes, keep some of a bigger pay for the quieter weeks.

Using the method with weekly or changing pay

Each time you're paid, ask what this money needs to cover before the following pay. Fund those obligations first, then contribute to later bills and goals. A monthly target can help you plan, but dividing it into two equal pieces won't necessarily cover a bill due before your second pay.

With changing income, plan around a cautious guess of your pay, but only give jobs to money that's actually arrived. A better-paid period can fund a future quiet one; money held for tax or business costs already has a job and isn't household spending money.

Adjust the plan for an unexpected cost

Say your car needs a $450 repair. Your transport and health amount now needs $800 instead of $350. There are already jobs for the whole pay, so adding $450 there means taking $450 from somewhere else.

One option is to use the $150 of breathing room, pause this month's $250 holiday contribution and trim everyday spending by $50. That's a choice the example has room to make, and the holiday slows down because of it. The figure compares “Before the repair” with “After a $450 repair”.

Before the repair

Transport and health$350Breathing room$150Holiday$250Everyday spending$550

After a $450 repairStill $0 left to assign

Transport and health$800Everyday spending$500

+$450 moved inBreathing room and holiday now $0$50 moved out

Change the plan when you make that decision, so the old holiday amount doesn't keep looking available.

If you can't cover the essentials

If the essentials cost more than the money available, keep the shortfall visible, even when there's nothing optional left to cut. The National Debt Helpline offers free, confidential financial counselling on 1800 007 007 if you need help working through bills or debts.

Getting a month ahead

Over time you can aim to live on last month's pay. Then this month's bills are covered on the 1st, even if payday comes later. Some budgeting apps call this getting a month ahead, and it works on paper too.

Give that money a job called “next month”. In the example, suppose the $150 breathing-room allowance survives the month and groceries finish $50 under. Moving both amounts adds $200 to next month, with $0 left to assign. Those dollars are reserved, so they aren't also available for the holiday or emergency fund.

Build towards enough to fund a full month of your plan. For this example that would be $5,000, including its savings contributions and later bills. There's no deadline: a repair might use the money you hoped to carry forward. Once you've saved a full month, spend each month from that money and put the pay that arrives towards the next one.

Doing it together on payday

With two monthly pays, the useful moment is when you sit down together and decide what both incomes need to do. One of you might enjoy this part while the other dreads another conversation about spending. I'd keep the first attempt to 20 minutes, with the usual jobs already written down so you're discussing changes rather than rebuilding the list.

Here, one pay brings $3,000 and the other $2,000, so there's $5,000 to plan together. Shared costs take $3,650 and savings goals $650, leaving $700. After $150 of breathing room, $550 is left for personal spending: $275 each in this example.

Equal personal amounts are a choice, not a rule. Splitting bills as a couple shows other ways to divide it.

Both pays in

Pay A $3,000+Pay B $2,000=To plan together $5,000

Shared jobs first

Shared costs$3,650Savings goals$650Left to assign$700

Then the last $700$0 left to assign

Breathing room$150Personal spending A$275Personal spending B$275

Start by checking what's due before either of you is paid again, and whether anything has changed since the last plan. Agree where the last dollars go, then stop when the remainder reaches $0. Both of you should leave knowing what the shared money is for, without needing to approve every personal purchase.

Between paydays, raise a change when it affects an agreed job, rather than reopening the whole plan over a coffee. If this becomes a weekly argument, try broader limits or a simpler shared plan. You don't have to enjoy the same level of detail to agree on what matters.

Zero-based budgeting vs 50/30/20 and envelopes

The 50/30/20 rule gives you broad shares for needs, wants and savings (half your pay for needs, 30% for wants and 20% for savings), while zero-based budgeting asks you to assign actual dollar amounts. If you already save consistently and mainly want broad limits, that may be enough detail.

Envelope budgeting keeps a running amount for each spending category, which helps when the decision is whether another purchase fits. You can use envelopes within a zero-based plan, as long as money outside the spending envelopes has jobs too. I'd try the full zero-based plan if those jobs make spending easier and you're willing to keep the balances current.

A printable zero-based budget template

Try it yourself: use the blank worksheet below with the money available for the period you're planning. Write each job and its amount, subtract it from what's left, and keep going until the remainder is zero. If there's money left, choose its job. A negative result means the plan needs changing before it's funded.

Before the next payday, check that what's in your account matches what's still set aside for each job, counting card payments that haven't come out yet. Whatever is still set aside carries into next month. Then plan the new pay.

A note from me

When a month goes wrong, I'd rather change the plan that afternoon than keep a perfect-looking version that no longer matches my account. Moving $450 around takes five minutes. Pretending the holiday money is still there is how a plan quietly stops working.

Calculations prepared on 28 October 2026, in AUD.

• The plan assigns $2,350 + $550 + $350 + $400 + $550 + $400 + $250 + $150 = $5,000. The successive remainders are $2,650, $2,100, $1,750, $1,350, $800, $400, $150 and $0.
• Current spending in the exact-plan illustration is $2,350 + $550 + $350 + $550 = $3,800. Cash retained is $400 + $400 + $250 + $150 = $1,200. $5,000 received minus $3,800 paid equals $1,200, with $0 unassigned. This simplified example starts with no existing balances.
• The repair adds $450 to transport and health, taking it from $350 to $800. Breathing room falls $150 to $0, the holiday contribution $250 to $0 and everyday spending $550 to $500. The reductions total $450, so assignments still equal $5,000.
• The joint payday example combines $3,000 and $2,000. Shared costs are $2,350 + $550 + $350 + $400 = $3,650; savings goals are $400 + $250 = $650. After $150 breathing room and $275 for each person, the remainders are $1,350, $700, $550, $275 and $0. This assumes both pays have arrived. It describes a joint conversation, not a Clova collaboration feature.
• The month-ahead step moves $150 unused breathing room and $50 unspent groceries to a new job: $150 + $50 = $200. Groceries then retains $500 for actual spending, breathing room is $0, and next month is $200. Total assignments remain $5,000. A full month of this plan is $5,000, including savings and later bills. No accumulation deadline or guaranteed surplus is assumed.
• The CTA shows a sample Annual costs card: $1,200 set aside of $1,500 at $400 a month, with $300 to go.
