Both personal loans and credit cards can help you cover a purchase or manage a financial shortfall — but they work very differently and the cost difference can be significant. Here is a clear comparison to help you decide which is right for your situation.
Short answer: For larger amounts or anything you cannot pay off quickly, a personal loan is almost always cheaper. Credit cards work best for small, short-term purchases you can clear within the interest-free period.
How they work
Personal loan
- Lump sum paid upfront
- Fixed interest rate
- Fixed repayment schedule
- Clear end date
- One application, one approval
Credit card
- Revolving credit limit
- Interest-free period (if paid in full)
- Flexible repayments (minimum only)
- No fixed end date
- Reusable once paid down
The cost difference
This is where the two products differ most significantly. In New Zealand:
- Personal loan rates typically start from 8.99% p.a. and go up to around 29.99% p.a. depending on your credit profile
- Credit card rates in NZ are usually between 20% and 28% p.a. — and that is after the interest-free period ends
If you borrow $10,000 on a credit card at 22% p.a. and only make minimum payments, you could be paying for years and spend thousands in interest. The same amount on a personal loan at 12% p.a. over 3 years has a clear end point and significantly lower total cost.
When a personal loan is better
- You need a larger amount ($2,000 or more)
- You cannot pay it off within a few months
- You want a fixed repayment and a clear end date
- You want to consolidate existing credit card debt
- You are making a planned purchase like a car, renovation, or holiday
When a credit card is better
- You need flexibility rather than a lump sum
- You can pay the full balance within the interest-free period
- You want to earn rewards on everyday spending
- The purchase is small and short-term
- You need an emergency buffer rather than a planned loan
Watch out: Making only the minimum repayment on a credit card means you could be paying it off for many years. Always aim to pay more than the minimum each month.
Can you use a personal loan to pay off a credit card?
Yes — and it is often a smart move. This is known as debt consolidation. If your credit card is sitting at 22% p.a. and you can get a personal loan at 12% p.a., moving the balance across saves you money immediately and gives you a fixed timeline to become debt-free.
The key is to close or reduce the credit card limit after consolidating so you do not end up with both the loan and a new credit card balance.

Is a personal loan cheaper than a credit card in NZ?
Usually yes. Personal loan rates in NZ typically start from 8.99% p.a., while credit cards often charge 20-28% p.a. For larger amounts or longer periods, a personal loan is almost always the cheaper option.
Can I use a personal loan to pay off my credit card?
Yes. This is debt consolidation. A personal loan at a lower rate can pay off your credit card balance, reducing your total interest cost and giving you a fixed repayment schedule with a clear end date.
How much can I borrow with a personal loan in NZ?
Through FYN Limited, personal loans are available from $1,000 up to $200,000 depending on your income, credit history, and the lender used.
Will applying for a personal loan affect my credit score?
Our initial enquiry does not affect your credit score. A formal credit check only happens once you choose to proceed with a specific lender.
