Buy now pay later
Short-term instalment credit at the checkout, interest-free but carrying late fees and affecting borrowing capacity.
BNPL splits a purchase into instalments, typically four payments over six weeks, with no interest charged if you pay on time. The retailer pays a fee to the provider rather than you.
Revenue comes largely from missed payments. Late fees are flat dollar amounts, which on small purchases represent an enormous effective interest rate.
Lenders assessing a mortgage application look at BNPL usage. Regular reliance on instalment credit for everyday spending signals cashflow stress and can reduce borrowing capacity.
The sector now falls under credit legislation in Australia, bringing responsible lending obligations and clearer disclosure. That reduces some risks but does not change the underlying issue, which is that instalments make it easy to commit future income without noticing.
Why late fees hurt
A $10 late fee on a $40 instalment is a 25% charge for being a few days late — an effective annual rate far beyond anything a credit card charges.
The bit people get wrong
Multiple concurrent BNPL arrangements are easy to lose track of because each is small. Together they can consume a large share of a pay cycle and appear on statements a mortgage assessor will read.
Common questions
Does BNPL affect my credit score?
Increasingly yes. Some providers report to credit bureaus, and missed payments can be recorded. Lenders also review your statements regardless of formal reporting.
Is it cheaper than a credit card?
Only if you always pay on time. A credit card cleared monthly costs nothing, while BNPL late fees on small amounts are proportionally severe.
Will it stop me getting a home loan?
Not automatically, but frequent use signals that income does not comfortably cover spending. Many brokers suggest closing accounts months before applying.
