Buy Now Pay Later: What Financial Institutions Won’t Tell You About the Real Costs

Almost 10% of e-commerce transactions in Australia are now paid using buy now pay later services, and more than half of US customers have already tried them. Whilst buy now pay later apps promise interest-free purchases and instant gratification, the real costs often remain hidden beneath attractive marketing messages.

What is buy now pay later, and why are financial institutions particularly quiet about certain aspects? This article examines how buy now pay later services actually work, the fees providers don’t advertise, the impact on credit scores, and the risks consumers face. Understanding these realities helps shoppers make informed decisions about whether buy now pay later Australia options truly suit their financial situation.

What Is Buy Now Pay Later and How Does It Actually Work?

Buy now pay later operates as short-term financing that splits purchases into equal instalments, typically paid over four to six weeks. When customers select this option at checkout, they pay approximately 25% of the purchase price immediately, with the remaining balance divided into scheduled payments. For instance, a £100 purchase converts into four £25 payments spread across six weeks.

The Basic Payment Structure Explained

The transaction comprises three parties: the customer, the merchant, and the purchase-now, pay-later provider. When a customer selects BNPL at checkout, the provider pays the merchant the whole amount ahead (less fees) and collects instalments directly from the customer. Most providers automatically withdraw payments from linked debit or credit cards, with autopay options designed to minimise default risk. Around 80 to 90 per cent of these transactions occur on debit cards, with average purchase sizes between £100 and £110.

Buy Now Pay Later Apps vs Traditional Credit

Credit card applications require comprehensive credit checks and waiting periods, whereas buy now pay later services demand only basic information: Australian bank account details, contact information, and proof of age. Most providers conduct soft credit checks that don’t affect credit scores. Note that 65 per cent of receivables originated by point-of-sale lenders involve consumers with credit scores above 700, contradicting assumptions that these services primarily target those with poor credit.

In contrast to credit cards, which charge interest on unpaid balances, buy now, pay later plans remain interest-free when payments are made on time. Credit cards offer flexible repayment schedules; BNPL requires fixed instalments on predetermined dates.

How Buy Now Pay Later Services Make Their Money

Despite offering interest-free terms to consumers, providers maintain robust revenue through multiple channels. Merchant fees constitute the primary income stream, ranging from 2 to 8 per cent per transaction compared to 1.3 to 3.5 per cent for standard credit cards. Additional revenue sources include late payment fees (Afterpay charges £12 initially, escalating if payments remain overdue), flat transaction fees, and interchange fees when customers use provider-branded cards.

The Hidden Fees Financial Institutions Don’t Advertise

Providers advertise interest-free terms, yet multiple fee structures generate substantial revenue. Missed payment charge income for all buy now pay later suppliers exceeded £65.75 million in the 2018-19 fiscal year, up 38% from the previous year. These charges accumulate rapidly for consumers who struggle with repayment schedules.

Late Payment Penalties That Add Up Quickly

Afterpay charges £15.29 for the first missed instalment, with an additional £10.70 if payment remains outstanding after seven days. For purchases costing more than £61.16, late fines are limited to 25% of the purchase price, or £103.97 in total. Zip charges a late payment fee of £7.63, capped at £76.30 annually. Research from Curtin University found that falling behind on a £61.16 purchase could result in effective annual interest rates reaching 28.25% for Afterpay, 29.32% for Zip, and 177.44% for Humm’s ‘Little Things’. Notably, 21% of buy now, pay later users, according to a survey, had missed a payment during the previous year.

Monthly Account-Keeping Fees

Several providers charge recurring account maintenance costs. ZipPay applies a £6.04 monthly fee, whilst Brighte charges £3.52 weekly. These fees continue regardless of whether consumers have active purchases.

Payment Processing Charges

Some services add fees to each repayment transaction. Payment processing charges of £4.51 apply per instalment with certain providers.

Establishment and Service Fees

Establishment fees vary considerably based on plan length, ranging from £7.64 for three-month terms to £137.53 for 48-60 month arrangements. One provider charges a one-off upfront fee of £382.25.

Bank Overdraft Fees from Failed Payments

When automatic payments fail due to insufficient funds, bank overdraft charges compound the cost of BNPL. Commonwealth Bank charges £22.93 per day plus 14.90% interest. Research shows that new buy now, pay later users experience 4.0% more overdraft charges than non-users.

How Buy Now Pay Later Australia Services Impact Your Credit Score

Since 10 June 2025, buy now, pay later services in Australia have operated under the National Consumer Credit Protection Act, fundamentally changing how these products interact with credit profiles. This regulatory shift introduced consumer protections whilst simultaneously expanding credit reporting obligations for providers.

Mandatory Credit Checks for New Accounts and Limit Increases

All buy now pay later providers must now conduct credit checks when customers apply for new accounts. These enquiries appear on credit reports and may influence credit scores. Providers also perform credit checks when assessing limit increases. Each application triggers a recorded enquiry, and numerous credit checks on a report can become a red flag for lenders.

The Shift to Positive Reporting

Consistent, on-time payments on buy-now-pay-later plans may positively affect credit scores. However, not all providers currently report additional information such as on-time repayments. This creates an imbalanced situation where responsible use provides limited upside to credit files, only downside if payments are missed.

Missed Payments Reported to Credit Bureaus

Payments made more than 14 days past the due date are considered missing. Providers can list defaults on credit reports if payment remains overdue for at least 60 days, equals or exceeds $229.35, and proper notices have been issued. Default listings remain on credit reports for two years, even after payment. Research shows that 34% of Australians who used buy now, pay later services have been late with payments

Impact on Future Loan Applications

Lenders review buy now pay later repayment history when assessing mortgage and loan applications. Outstanding debts, repayment behaviour, and overall financial management all factor into creditworthiness decisions. Even small monthly repayments can reduce home loan borrowing capacity by several thousand dollars.

Multiple BNPL Accounts Creating Red Flags

Frequent use of buy now, pay later, particularly across multiple platforms, may signal financial stress or overreliance on short-term credit. Multiple active accounts suggest potential overcommitment to lenders, making loan assessors question debt management capabilities.

What Providers Leave Out About the Real Risks

Regulatory changes introduced modified responsible lending frameworks that reduce assessment requirements based on risk factors. For loans under £2,288.48 with the same provider, a negative credit check is sufficient, covering only identity and defaults. Loans exceeding this threshold require partial credit checks, including other debts. In essence, these modified assessments permit providers to overlook comprehensive financial circumstances that traditional lenders must examine.

The Reality of ‘Modified’ Responsible Lending Assessments

Providers can elect to comply with modified obligations rather than full responsible lending assessments. This creates situations where consumers receive credit without thorough verification of existing BNPL products, other credit commitments, or significant defaults. The absence of stringent affordability checks allows providers to ignore whether consumers possess sufficient income to meet repayment obligations.

Overspending Without Safety Nets

One in five users cut back on essentials such as meals to make buy now pay later repayments on time. Consumers prioritise BNPL payments over household bills, credit cards, and mortgage payments. Some 15% took out additional loans to meet buy-now-pay-later commitments. Financial counsellors report that clients use BNPL for groceries by purchasing gift cards, suggesting it is used for day-to-day survival rather than discretionary purchases.

Managing Multiple Buy Now Pay Later Services

A 2022 survey found that 84% of financial counselling clients with BNPL debts tried to manage their existing debt by opening additional accounts. Some clients juggle 12 payments per fortnight across multiple providers. Around 40% of shoppers use more than one BNPL provider simultaneously.

The True Cost Compared to Lay-by Options

BNPL constitutes debt, whereas lay-by does not. This distinction matters for loan applications and credit assessments. Lay-by requires no credit checks or bank accounts, making it accessible without debt obligations. Marketing BNPL as similar to lay-by misleads consumers about the financial commitment involved.

Conclusion – Buy Now Pay Later

Buy now pay later services present themselves as convenient, interest-free alternatives to traditional credit, yet the reality proves far more complex. Late payment penalties, account-keeping charges, and credit score implications create substantial financial burdens that providers rarely highlight upfront. Without a doubt, consumers deserve complete transparency about these costs before committing to instalments. Armed with this knowledge, shoppers can evaluate whether these services genuinely benefit their financial wellbeing or simply create additional debt obligations disguised as convenient payment options.
