Personal Loan vs Credit Card: Which Is Better for Your Situation?

The most significant difference between personal loans and credit cards is the interest rate. Personal loan rates in Australia typically range from 6% to 15% for secured loans and 8% to 20% for unsecured loans, depending on the borrower's credit profile and the lender.

Quick reality check. Credit card interest rates for purchases range from 13% to 22%, with the average around 18% to 20%. On a $10,000 balance, the difference between 10% (personal loan) and 20% (credit card) is approximately $1,000 per year in interest. Over a three-year repayment period, the personal loan at 10% costs approximately $1,600 in total interest, while the credit card at 20% costs approximately $3,400 — more than double.

This makes personal loans significantly cheaper for larger, longer-term borrowing. However, some credit cards offer interest-free promotional periods that can be cheaper than any personal loan if you pay within the promotional window.

Personal loans have fixed monthly repayments over a set term (typically one to seven years), which means your debt is guaranteed to be paid off by the end of the term. This structured repayment forces discipline and provides certainty about when you will be debt-free.

Credit cards have flexible repayments — you can pay any amount above the minimum, which provides flexibility but also enables the trap of minimum payments that barely reduce the balance. The minimum payment on a credit card is typically 2% to 3% of the outstanding balance, which means the payment amount decreases as the balance decreases, extending the repayment period indefinitely. A $10,000 credit card balance at 20% with minimum payments takes over 25 years to pay off.

The same $10,000 on a five-year personal loan at 10% is paid off in exactly five years with fixed monthly payments of approximately $212.

Worth knowing: A personal loan is typically better when you're borrowing a specific amount for a defined purpose (car buy, home renovation, debt consolidation), when you want certainty about repayment dates and amounts, when you need to borrow more than $5,000, when the repayment period will be longer than 12 months, and when you want the discipline of fixed repayments to ensure the debt is eliminated. Personal loans also work well for consolidating multiple credit card debts into a single lower-rate payment.

When comparing personal loans, look beyond the headline rate — check the comparison rate (which includes fees), any application or ongoing fees, whether you can make extra payments without penalty, and the total cost over the full loan term. Some lenders offer fee-free personal loans with competitive rates, particularly online-only lenders.

A credit card is typically better when you need revolving credit for variable expenses rather than a single buy, when you can pay the balance in full each month (avoiding interest entirely), when you want to take advantage of a 0% balance transfer offer to pay off existing debt, when the buy qualifies for an interest-free period (typically 55 days on purchases if you pay in full), and when you want rewards points, travel insurance, or buy protection that come with premium cards. Credit cards are also more practical for everyday transactions, online purchases, and international travel.

The key principle: credit cards are an excellent financial tool when used for convenience and paid in full each month. They become expensive debt when balances are carried over. If you consistently carry a balance, switching to a low-rate card (13% to 15%) or a personal loan will save you money.

Use our Personal Loan Calculator to model repayments and total interest on a personal loan at different rates and terms. Compare this with our Credit Card Payoff Calculator to see how long it would take to pay the same amount on a credit card and the total interest cost.

Bottom line? For those considering consolidating multiple debts, our Debt Consolidation Calculator models the savings from combining credit cards and other debts into a single loan. When making your decision, consider not just the interest rate but also your personal financial discipline, the purpose of the borrowing, and how quickly you can realistically repay the debt. The cheapest option is always the one you pay off fastest.
