Personal Loan vs Credit Card: Which Is Cheaper for Borrowing?

📊 The real rate gap🔗

🎯 The essential: The gap between typical rates isn't marginal, it's often the difference between the high teens or twenties and the single digits.

The gap isn't marginal, it's frequently the difference between a rate in the high teens or twenties and one in the single digits, for borrowers with a solid credit history.

✅ When a personal loan is genuinely the cheaper option🔗

Anything borrowed for longer than a billing cycle or two, a car, a large one-off expense, or consolidating existing high-interest debt, tends to come out cheaper on a personal loan's lower rate and fixed repayment schedule. A fixed term also builds in a genuine end date, rather than a credit card balance that can be carried indefinitely at minimum payments.

💳 When a credit card still makes sense🔗

For spending that will genuinely be paid off within the card's interest-free period, commonly up to 55 days on new purchases, a credit card can be free borrowing in practice, plus any rewards or purchase protections that come with the card. The moment a balance carries past that interest-free window, the comparison flips sharply back toward whichever option has the lower ongoing rate.

🔁 The structural difference: revolving vs fixed🔗

A credit card is revolving credit, the limit refills as you pay it down, which suits ongoing, unpredictable spending but makes it easy for a balance to persist indefinitely. A personal loan is a fixed amount over a fixed term, less flexible for spontaneous spending, but with a repayment schedule that guarantees the debt is gone by a specific date rather than depending on paying more than the minimum.

📵 Why unsolicited credit limit increases stopped🔗

If it feels like banks used to offer credit limit increases far more often than they do now, that's a real, deliberate regulatory change, not a shift in bank generosity. Since January 2019, ASIC has required credit providers to assess whether a customer could realistically repay a card's full credit limit within three years before approving a new card or a limit increase, and the government separately banned banks from sending unsolicited invitations to increase a limit at all. Both changes followed an ASIC review that found more than one in six credit card holders were struggling with their debt, often on cards with limits well beyond what a genuine repayment assessment would have supported.

The practical effect is that credit cards are somewhat harder to get approved for, or to have the limit raised on, than they were a decade ago, which is part of why a personal loan, with its more thorough application, doesn't actually feel like the "easier" option it might once have been by comparison. Either application also leans heavily on your credit score. It's a reasonable trade worth knowing about: slightly more friction upfront, in exchange for a system less likely to hand someone a limit they can't realistically pay down.

🧮 A worked example🔗

A $10,000 balance at a credit card's average 21% rate, paid off over three years, accrues substantially more interest than the same $10,000 borrowed as a personal loan at 10% over the same term, purely from the gap in rate, before even accounting for a credit card's tendency to attract only minimum payments rather than a disciplined fixed schedule.
