Budgeting

Updated 10 November 2026 | A practical Australian household budgeting guide

A budget is a plan for the money available to your household and the jobs that money needs to do. It can help you pay regular bills, prepare for occasional costs and work towards a goal. It is also a way to spot a shortfall early, while there is more time to respond.

You do not need a particular app, income level or financial background to start. A notebook, spreadsheet or a bank’s transaction records can be enough. What matters is using realistic figures and reviewing them when circumstances change.

This ebook follows three steps: calculate spendable income, identify expenses, then compare the two and make a practical plan. The examples are fictional and illustrate the method. They are not estimates of what every household should earn or spend.

ASIC’s guide to making a budget and free budget planner provide a useful starting point. This is general information, not personal financial, tax or credit advice.

Start with money you can actually use

For day-to-day planning, take-home pay is more useful than the salary printed in a job advertisement. Check payslips and the amounts deposited into your account. A remuneration package may include employer super or other benefits, so distinguish the package from cash salary.

For an Australian resident earning a cash salary of $90,000 in 2026–27, income tax is $17,520 before offsets. Adding a full 2% Medicare levy of $1,800 gives $19,320, leaving $70,680 a year, or an average $5,890 a month.

This illustration uses the 2026–27 resident tax rates. It assumes no deductions, tax offsets, student-loan repayments, Medicare levy surcharge or other adjustments. Your payslip and final tax assessment can differ. Use the money you actually receive for your working budget and allow for any expected tax bill.

Employer super is generally retirement saving rather than spendable household income. Where a $90,000 cash salary is entirely qualifying earnings and super is additional, 12% SG is $10,800 before fund tax. If the quoted package includes super, that is a different calculation. The ATO explains current SG and Payday Super requirements.

Include the other sources, with their costs

List wages, relevant government payments, child support and regular investment receipts. For self-employment or side work, gross receipts are not all available to spend. Allow separately for business expenses, tax and any GST or other obligations. Rent also has property expenses and possible tax attached.

Do not assume last year’s dividend, bonus or benefit payment will continue unchanged. Use the current payment notice or a conservative estimate, and make uncertain income visible rather than hiding it in a single confident total. Check how changes in income could affect government entitlements.

Borrowing, selling an asset and transferring money from your savings account can provide cash, but they are not recurring earnings. Record them separately so they do not disguise a continuing spending shortfall.

Use one common period

A monthly planning view can help compare different payment cycles. These conversions give annualised monthly averages:

• Weekly amount: multiply by 52 and divide by 12.
• Fortnightly amount: multiply by 26 and divide by 12.
• Quarterly amount: divide by three.
• Half-yearly amount: divide by six.
• Yearly amount: divide by 12.

For example, $500 a week is about $2,166.67 per average month, not $2,000. Keep unrounded figures in your calculations and round the displayed total at the end. These averages do not predict the exact cash received in a particular calendar month; some years also contain an additional weekly or fortnightly payday.

A running example

Our fictional household has $5,890 a month of take-home salary and another $1,500 of regular net household income. Total spendable income is $7,390 a month, or $88,680 a year. The second amount is an assumption for this example, not an entitlement estimate.

If income varies, also prepare a lower-income scenario and a calendar of likely payment dates. ASIC’s casual-income guidance can help you plan around uncertainty. A good month should not automatically become the baseline for every month that follows.

Find the actual spending

Review transactions from the past few months, then look across a full year for annual and seasonal costs. Include cash purchases and bills paid from another account. ASIC’s spending-tracking guide explains how to group transactions and identify recurring costs.

Separate essential costs from spending you can change, but avoid treating every variable expense as optional. Groceries, medicines and transport vary while remaining necessary. Rent, insurance or a mortgage payment can also change at renewal or when rates change.

Count each amount once

A purchase made on a credit card is spending. Moving money from your bank account to pay that card is normally repayment of the same purchase, not a second grocery or shopping expense. Transfers between your own accounts are not new household expenditure either.

Choose a consistent method. If purchases are included by category, exclude the matching card or BNPL repayment from new-spending totals, while separately allowing for interest, fees and repayments of older debt. Keep a payment calendar as well: repayments still need enough cash on their due dates.

For buy now pay later, list every outstanding instalment across providers. Splitting a price into instalments does not reduce the total cost or remove the obligation to repay.

Tools are optional; check permissions

You can review statements manually or use a bank or budgeting tool. Check that categories are accurate: an automatic label may confuse a transfer, refund or business purchase with household spending.

Before linking financial accounts to an app, check who operates it, how data is shared, what permissions you grant, the cost and how to withdraw consent. The Consumer Data Right provides a regulated route for sharing data with accredited recipients or authorised representatives. Do not assume every app uses that route or that an app’s popularity proves it is suitable. You can make a budget without connecting accounts.

The example household’s monthly costs

The following totals are fictional planning amounts. Each item is counted once. Annual bills have been converted to monthly amounts to set aside.

• Housing and utilities — $3,060: mortgage $2,500; rates $150; electricity and gas $200; water $50; internet and phones $160.
• Daily living — $1,750: groceries $900; takeaway and eating out $400; work lunches and coffee $250; clothing and personal care $200.
• Transport — $950: car loan $450; fuel and maintenance $250; registration and car insurance $150; public transport $100.
• Health and personal insurance — $440: health insurance $250; personally paid life or income protection cover $100; medical and dental $50; pharmacy $40.
• Lifestyle and family — $870: subscriptions $70; hobbies $200; children’s activities $300; holidays $250; gifts and donations $50.
• Older debt and administration — $290: $150 towards a previous credit-card balance, $100 towards earlier BNPL purchases, and $40 for accounting costs.

Total: $7,360 a month, or $88,320 a year. The older card and BNPL purchases are not also included in the current spending categories. Insurance paid from super is not a second household cash payment; check where a premium is actually deducted.

Prepare for irregular costs

Set aside money for registration, insurance, repairs, school costs and planned holidays. Check renewal notices, contracts and quoted prices before assuming a percentage increase. A blanket inflation allowance will not fit every item.

If $4,800 of expected annual costs are already included in your budget, reserving $400 a month for them does not create another $400 expense on top. It moves the budgeted money to where it can wait for the bills. If a bill is due sooner, you may need a larger initial reserve.

Compare the totals

In the example, monthly income of $7,390 less monthly costs of $7,360 leaves $30. Annual income of $88,680 less annual costs of $88,320 leaves $360. This is a small planned surplus before any costs or goals not yet included.

A budget is not a guarantee. A small surplus can disappear after a price rise or missed shift. Check that the figures include everything, test a less favourable month and compare the plan with actual transactions.

Match the plan to payment dates

An annual surplus does not ensure there is cash on the day a bill is due. Mark paydays, rent or mortgage dates, loan instalments and large bills on a calendar. Allocate enough from each payday and keep the bill reserve separate from money available for discretionary spending.

Review the plan after a change in work, housing, family circumstances or interest rates. Regular brief check-ins can reveal a problem before it becomes a string of late payments.

Using a surplus

Give extra money a purpose that fits your circumstances. You might build a cash buffer, pay down expensive debt or save for a known expense. ASIC suggests three months of expenses as a useful emergency-fund target, but the appropriate amount depends on income stability, responsibilities and access to support. Starting with a smaller achievable amount still helps.

Extra debt repayments can reduce future interest, subject to the loan terms and any fees. This is an avoided borrowing cost, not a guaranteed investment return available for every debt. Keep enough accessible money for essential bills and check whether extra repayments can be accessed again if needed.

For longer-term goals, consider timeframe, investment risk and access to money. Extra super contributions are generally preserved until a release condition is met and are subject to eligibility and caps. A personal budget surplus alone does not determine the right investment.

Responding to a deficit

Start with essentials and urgent obligations. Identify which costs can be reduced or delayed without compromising safety, health or necessary insurance. When comparing a refinance or cheaper plan, include fees, loan term, cover and restrictions rather than comparing only the advertised payment.

If repayments are becoming difficult, contact the lender or provider promptly and ask about hardship assistance. Do not rely on another loan to cover a recurring gap without understanding the total cost and risks. ASIC’s hardship guidance explains the available steps.

A deficit is not always solved by cutting discretionary spending. Income, rent, health and caring needs can leave little room. Free, independent and confidential financial counselling can help assess options and negotiate with creditors. The National Debt Helpline is available on 1800 007 007.

Your next step

Choose one manageable action: collect statements, list upcoming bills or check whether your total includes transfers twice. Complete a first version, then improve it as you learn. If you are balancing several goals or considering a major financial change, an adviser can help connect the budget with your broader circumstances.
