That can be easy to fit into this week's spending. The harder part comes later, when another $40 leaves your account on the same day as a payment for something you bought last week. I'd start with those dates. They tell you more about what you can afford than the size of any one payment. ## How does Afterpay work? Buy now pay later, often shortened to BNPL, lets you receive a purchase before you've finished paying for it. The amount left to repay is money you owe, even if there's no interest. Afterpay's Australian **Pay in 4** is one example. Its [payment explanation](https://www.afterpay.com/en-AU/how-it-works) describes four interest-free payments over six weeks: roughly a quarter at checkout, followed by three automatic deductions about two weeks apart. This guide uses that pattern to explain the budget, without recommending a provider. For a $160 purchase, that's $40 now and $40 in each of two, four and six weeks. Splitting it changes when the money leaves; the purchase still costs $160 before any fees. Other products can have different schedules and charges, including products from the same brand, so check the full cost and every payment date before you agree. ## Interest-free can still cost money [Moneysmart's BNPL guidance](https://moneysmart.gov.au/other-ways-to-borrow/buy-now-pay-later-services) warns about late, account, setup and processing fees. Your bank may also charge an overdraft fee, and paying instalments by credit card can mean card interest. Late fees are the ones that catch people out. On Afterpay's Pay in 4, missing a payment on that $160 purchase can cost $10, with more if it stays overdue, up to $40 in late fees in all. The cap limits the fees; it doesn't cancel the amount you still owe. [Afterpay's Pay in 4 fee page](https://www.afterpay.com/en-AU/help/900005359783-Is-there-a-cost-to-using-Afterpay) says orders over $40 can incur $10 for a missed payment and a further $7 if it remains overdue seven days later. Total late fees per order are capped at the lower of 25% of the original order value or $68. For orders of $40 or less, a single late fee of 25% of the order value may apply. ## Approval and what the payments leave you Being approved for a purchase does not tell you how comfortably its payments fit beside rent, food and the other instalments already waiting. The provider checks the credit application; your own pay plan shows what another payment would leave to live on. BNPL is regulated credit, with responsible lending, hardship and complaints obligations. Applications and missed payments can affect a credit report, so a purchase has consequences beyond the amount shown at checkout. Providers need an Australian credit licence or a qualifying transitional arrangement, along with Australian Financial Complaints Authority membership. For eligible low cost credit contracts, providers can elect to use modified responsible lending obligations. They still have to make inquiries about the applicant's finances and assess whether the credit is unsuitable. Applications can trigger credit checks, repeated checks can influence a score and late or missed payments can be reported. What appears depends on the provider and reporting involved; there is no fixed score change for using BNPL.

The consumer credit rules took effect on 10 June 2025; transitional licensing arrangements can continue until ASIC decides an eligible application.

Even if each one takes payments fortnightly, together they can draw money several times between your paydays. Here's a fictional example. All amounts are AUD and all income, living costs and payment dates are illustrative, with no fees, new purchases or other income assumed. You receive $1,400 after tax on 12 November, with the next pay two weeks later. Your plan for that pay is: | What this pay needs to cover | Amount | | --- | ---: | | Rent | $600 | | Food and transport | $280 | | Bills set aside | $150 | | Savings and a buffer | $100 | | Left before BNPL payments | $270 | There are three unfinished purchases. Each follows the four-payment pattern above, and the first payment has already been made on each. **Worked example** ### The three purchases, pay by pay | Purchase and original price | Next payment | Still owed on 12 November | | --- | --- | ---: | | Shoes, $160 | $40 on 13 November | $120 | | Headphones, $240 | $60 on 17 November | $180 | | Clothes, $200 | $50 on 20 November | $150 | | **Total** | **$150 this fortnight** | **$450 overall** | That leaves **$120 available**: $1,400, less $1,130 for rent, food, bills and savings, less $150 of instalments. Treating the $270 left before repayments as spending money would overstate what you can spend by $150. The same $150 comes out of the next two pays, which is what clears the $450, so a new purchase would cut into every one of them. Before adding a purchase, check every pay it would touch, especially if your next roster has fewer shifts. A payment you can make this fortnight may leave you short in the next one. ## Put the whole schedule into your budget Every instalment needs its money waiting before it comes out. Open each BNPL account and write down every unpaid amount and due date, including any fees already owing, then group them under the pay that needs to fund them. If a deduction is due on payday, include it in the earlier pay's plan unless you know the wages will arrive first. On payday, set aside that group's total alongside essentials and other commitments, and keep it in the account the provider will debit. A reminder helps you remember the date; having the money reserved is what lets the payment go through. Our guide to [money left before payday](/blog/money-left-before-payday) explains the same difference between an account balance and money available after commitments. If you're recording spending by category as well, count each purchase once: either the full $160 as shopping when you buy it, with repayments tracked as debt, or each instalment as shopping when you pay it. Whichever you choose, keep the remaining debt visible. You can start with our [budget planner](/tools/budget-planner), adding repayments to the costs your pay must cover, and if you're building the whole plan for the first time, [how to make a budget](/blog/how-to-make-a-budget) walks through the other costs to include. Clova keeps this picture for you. Each pay gets a plan with your upcoming bills and their due dates beside it, so an instalment you've already planned for is still in view before you agree to another one.

It becomes a problem for the budget when paying it means borrowing again or going without essentials. There isn't a particular number of orders that makes the difference; it's whether the payments fit the income you actually have. If you're putting food on BNPL because old instalments have used up the grocery money, the next pay is already being spent twice. Paying BNPL from a credit card can carry the shortfall further forward. If a card balance is building too, our [credit card repayment guide](/blog/pay-off-credit-card) explains how to make room for repayment without relying on new spending. I'd pause new purchases while you work out the amount owed and what you can afford after essentials. Removing the payment option from saved checkouts can make that pause easier to keep. If the repayments still don't fit, changing the dates in your calendar won't solve the shortfall; that's the point to ask for help. ## If you can't make a payment Contact the provider and ask for its hardship service, ideally before the due date. [Moneysmart confirms](https://moneysmart.gov.au/other-ways-to-borrow/buy-now-pay-later-services) that BNPL providers must have hardship and complaints services. Explain what you can afford and ask what options are available. Check any agreed change in writing before relying on a new schedule. For free, confidential help with the whole picture, call the [National Debt Helpline](https://ndh.org.au/) on **1800 007 007**. A financial counsellor can help you work through debts and the next step without selling you a loan. This guide is general information, not personal financial advice. The worked budget is an example, not an assessment of what you can afford. ## A note from us We believe a small instalment belongs beside everything else a pay has to cover before another purchase is agreed to. When payments already feel difficult, getting help matters more than making a tidier list. ## Common questions ### How does Afterpay work? Afterpay's Australian Pay in 4 product splits a purchase into four interest-free payments, normally starting at checkout with the remaining payments about two weeks apart. Check the actual schedule before buying. Other Afterpay products have different costs and terms. ### Does buy now pay later affect your credit score? It can. Moneysmart says BNPL applications trigger credit checks and late or missed payments can be reported. What appears depends on the provider and reporting involved; there is no fixed score change for using BNPL. ### Is buy now pay later regulated in Australia? Yes. BNPL contracts fall within Australian consumer credit regulation, including licensing, responsible lending and hardship protections. Eligible low cost credit contracts can use modified responsible lending rules. ASIC also provided transitional licensing arrangements. ### How do I budget for several BNPL purchases? List every remaining payment by date across all accounts, then group them by the payday that must fund them. Subtract each group's total alongside essentials and other commitments before deciding what is available to spend. Include payments due on payday unless you know your pay will arrive first. ## Sources 1.
