3 things to know about buy now, pay later vs a personal loan

BNPL and personal loans work very differently. Before you choose, here's what to understand about costs, credit file implications, and which option suits what.

Buy now, pay later services have become a familiar part of how many Australians pay for things, from clothing and electronics to medical bills and car repairs. For smaller purchases in particular, the appeal is obvious: instant access, no interest, and repayments spread over a few weeks.

As the number of people borrowing through these platforms has grown, so too has the question of whether a personal loan might be a better fit. The two products work differently, and the right choice depends on what you’re buying, how much you need, and how you plan to manage repayments.

Before choosing between them, it helps to understand how each one works.

How buy now, pay later works in Australia

Buy now, pay later platforms let you make a purchase and split the cost into instalments, typically four fortnightly payments for the most common short-term products like Afterpay and Zip Pay. You receive the product upfront and pay over the following weeks.

The business model works because merchants pay a fee to the platform for the service. That merchant fee is how providers like Afterpay make money on the no-interest model, rather than charging borrowers directly. For short-term products, the interest-free arrangement is real, but it holds only for the duration of the scheduled repayment period and only if you pay on time.

What’s changed in recent years is that many platforms have expanded into longer-term products with larger credit limits and, in some cases, interest charges. Zip and Latitude, for example, offer products that operate more like revolving credit accounts than the simple four-instalment model. These longer-term BNPL products carry interest rates that can be comparable to or higher than a personal loan, so the zero-interest assumption doesn’t hold across the full product range.

The range of things Australians now use BNPL for has also broadened. Early adoption was concentrated in fashion and small electronics. Now platforms are integrated into dental practices, veterinary clinics, travel booking sites, and car service centres. That shift into larger, less discretionary expenses changes the risk profile for borrowers. Missing a $200 fashion repayment is inconvenient; missing a $1,200 dental procedure repayment can cascade into multiple late fees and a credit file entry.

In 2024, buy now, pay later providers in Australia came under the National Consumer Credit Protection Act. Before that change, BNPL operated outside the regulatory framework that applies to personal loans, credit cards, and mortgages. The legislation closed that gap, requiring providers to conduct credit assessments in certain circumstances and giving consumers formal credit protections. It also means that missed payments and defaults through BNPL platforms can now appear on your credit file.

How a personal loan works

A personal loan is a fixed-term borrowing arrangement through a bank, credit union, or non-bank lender. You borrow a set amount, agree to a repayment schedule, and pay interest on the outstanding balance over the term.

Personal loans in Australia typically run from one to seven years. The interest rate can be fixed (the same rate throughout the term) or variable, which can move during the loan period. Most Australians choose fixed rate personal loans for the predictability of set repayments each month.

Personal loans come in two forms.

A secured personal loan is backed by an asset, most commonly a vehicle. The lender holds security over the asset, which reduces their risk and generally translates to a lower interest rate. If you default, the lender can claim the asset.

An unsecured personal loan has no asset attached. It’s based purely on your creditworthiness and income. Rates are typically higher than secured loans to reflect the lender’s increased exposure, but unsecured loans offer more flexibility because no asset is at risk.

For amounts above a few thousand dollars, personal loans offer a structure that BNPL products generally can’t match: longer terms, fixed repayments, and a single monthly payment rather than multiple separate orders running at once.

1. Buy now, pay later is cost-effective only when you pay on time

Most buy now, pay later platforms charge no interest, which sounds straightforward. The cost structure runs through fees instead.

Late fees are charged when you miss a scheduled repayment. These vary by provider. Some cap the total fee at a portion of the order value; others apply a flat dollar amount per missed payment. If you have several BNPL orders running at the same time and miss a payment on any of them, the fees compound.

Some platforms also charge:

• Account-keeping fees (a monthly or annual charge to hold the account)
• Payment processing fees (charged when you pay using a credit card rather than a debit card or bank account)
• Fees for specific plan types, particularly for longer repayment periods The fee-based cost model means that for a one-off, modest purchase you can comfortably repay within the scheduled window, BNPL is often the lower-cost option. The challenge appears when repayments don’t align with your cash flow, or when you’re managing several orders across different platforms simultaneously.

The other consideration is product creep. Many Australians who started using BNPL for small fashion or tech purchases have drifted toward using it for larger expenses: medical procedures, home goods, car-related costs. At that point, the short repayment window puts real pressure on the monthly budget, and what was a low-cost arrangement becomes a source of cash flow strain.

Some BNPL providers have introduced products with repayment terms of six to eighteen months. These carry interest rates that can be comparable to or higher than a personal loan, so the “no interest” assumption doesn’t hold across the full product range.

2. Personal loans suit larger amounts and longer repayment windows

BNPL platforms typically cap borrowing limits at a few thousand dollars. Afterpay’s limit starts at a few hundred dollars and may increase over time based on your account history, while Zip’s products extend higher but still operate within short repayment windows for the standard product tier.

For larger expenses, these limits and timelines create budget pressure. Repaying $4,000 across four fortnightly instalments means paying $1,000 per fortnight. For most households, that’s a meaningful impost on cash flow for two months.

A personal loan lets you borrow more and spread the cost across a term that suits your income. The same $4,000 at a competitive personal loan rate over two years comes to around $175 to $200 per month, depending on the rate and fees. The total interest cost over the term adds to what you pay, but the monthly impact is far more manageable than the accelerated BNPL repayment schedule.

The comparison shifts depending on the amount and the term:

For expenses you can clear in a few weeks without financial strain (a small appliance, a clothing purchase, a course fee) BNPL keeps the total cost close to zero if you pay on time. For anything that would stretch your budget over the BNPL repayment window, a personal loan’s longer term and lower monthly payment tends to be a better fit.

The typical use cases where personal loans make more sense include car repairs, dental and medical procedures, home appliances, travel, and debt consolidation. These purchases share a common characteristic: the cost is large enough that forcing it into an eight-week window creates real pressure on a household budget.

3. Buy now, pay later activity can affect your ability to borrow

The 2024 regulatory changes brought BNPL under the National Consumer Credit Protection Act, the same framework that governs personal loans, credit cards, and home loans. This has several practical implications that many borrowers haven’t yet absorbed.

Credit file exposure. Under the previous regulatory framework, most BNPL providers didn’t report to credit bureaus. Missed payments and defaults didn’t appear on your credit file. That changed with the 2024 NCCP amendments. Providers are now required to conduct credit assessments in certain circumstances, and missed payments can now appear on your credit report. A pattern of late BNPL payments is no longer invisible to lenders.

Lender assessment of existing commitments. Lenders assessing a mortgage or personal loan application look at your existing financial commitments to determine your capacity to service additional debt. Active BNPL repayment schedules count as liabilities in this assessment. If you’re currently juggling four BNPL orders across two platforms, a lender sees those as ongoing financial obligations, even if the individual amounts are small.

The cumulative effect on a home loan application can be meaningful. A lender calculating your borrowing capacity uses your net income minus your committed expenses. BNPL repayments, even at $200 to $400 per month across multiple orders, reduce the disposable income figure the lender works with. That can lower the maximum loan amount you qualify for.

Signals about cash flow. Beyond the arithmetic, lenders also make qualitative assessments. Frequent, ongoing BNPL usage, particularly for everyday purchases, can signal that a borrower relies on short-term credit to manage month-to-month expenses. This is the kind of pattern that prompts additional scrutiny during an application assessment.

If you’re planning to apply for a home loan or significant personal loan in the next six to twelve months, reducing your BNPL activity before applying is worth considering. Clearing existing BNPL commitments and avoiding new ones in the lead-up to an application gives lenders a cleaner picture of your finances.

When each option makes sense

The choice between BNPL and a personal loan comes down to a few practical factors.

Amount. For purchases under $1,000 that you can comfortably repay within the BNPL window from your existing cash flow, BNPL is often the lower-cost option. For anything above that threshold where repayment would strain your budget, a personal loan generally provides better structure.

Repayment timeline. BNPL’s strength is speed and short-term convenience. If you want the product now and can repay quickly, it works well. If the expense warrants spreading over twelve to thirty-six months, a personal loan is designed for exactly that.

Your current borrowing plans. If you’re within six to twelve months of applying for a home loan, car loan, or other significant finance, keeping BNPL activity minimal reduces the visibility of those commitments to lenders. A personal loan consolidating existing BNPL balances can sometimes improve your credit position for a subsequent home loan application. This is worth discussing with a broker.

The total cost calculation. Don’t compare BNPL’s zero interest against a personal loan’s stated rate without accounting for fees. BNPL late fees on a missed $400 payment can cost $15 to $30 per incident, per platform. Across multiple orders and a missed payment here and there, the true cost of BNPL rises. A personal loan’s interest is predictable and fixed in advance; BNPL’s cost depends on your payment behaviour.

Credit file impact. Post-2024, both products can affect your credit file. Missing a BNPL payment is now reportable in the same way a missed loan repayment is. This changes the calculus for borrowers who previously treated BNPL as consequence-free short-term spending.

Using both responsibly

BNPL and personal loans aren’t necessarily in competition. Many people use both at different times for different purposes. A borrower might use BNPL for a $300 purchase they’ll repay within a month, and a personal loan for a $6,000 car repair they need to spread across two years. The key is matching the product to the purpose and being clear-eyed about the costs and commitments involved in each.

Where problems arise is in treating BNPL as a spending tool rather than a credit product, or using it for purchases whose total cost would be better served by a more structured borrowing arrangement. The 2024 regulatory changes reflect a broader recognition that BNPL is credit, with the same potential for financial stress as any other borrowing when used without a clear repayment plan.

A few habits that help:

Track all active BNPL orders in one place. When purchases are spread across Afterpay, Zip, and a third platform, it’s easy to lose track of how many repayments are running at once. Checking the total fortnightly obligation across all platforms gives you a clearer picture of what you’ve committed to.

Match BNPL to purchases you’d make anyway. Using BNPL to bring forward a purchase you needed and would have bought regardless is different from using it to make a purchase feel more affordable than it is. If you wouldn’t buy something at full price today, a fortnightly instalment plan doesn’t change the underlying cost.

Check your credit file before a loan application. Under the 2024 NCCP changes, you can request a copy of your credit report through one of the main credit reporting bureaus: Equifax, Experian, or illion. Checking it six months before a planned loan application gives you time to address anything that needs attention, including any BNPL-related entries.

How a finance broker can help

A finance broker has access to a panel of personal loan lenders and can compare options across interest rates, fees, loan terms, and eligibility requirements on your behalf. Rather than applying to multiple lenders individually (which can generate multiple credit enquiries on your file and drag down your credit score), a broker identifies which lenders suit your situation before you formally apply.

If you’re weighing up whether a personal loan suits your situation better than a BNPL arrangement, a broker can run the numbers for your specific circumstances and show you what’s available across the lending market.

For borrowers with existing BNPL commitments who are planning a home loan application, a broker can also advise on how those commitments might be viewed during assessment, and whether consolidating them into a personal loan before applying would improve your borrowing position.
