What is a Low Interest Credit Card?

  • A low interest credit card is exactly what is says.
  • It won't offer any perks like rewards, cashback or Airpoints dollars, but the interest rate will be considerably lower.
  • Most low interest credit cards come with some form of balance transfer, so you get the best of interest-free periods on existing debt and low interest on ongoing debt. 
  • Like any credit card you can avoid interest altogether by clearing your balance in full every month.
 
Picking the Best Low Interest Credit Card
  • The trick is to pick a card with a low interest rate, a zero (or very low) fee, interest free terms on balance transfers and some sort of interest-free period for new purchases. When chosen correctly, the right card will maximize your savings available.
  • Credit card interest is a killer, so the lower that is, the better the card. But watch the fees - our best buys below consider fees and interest rates to ensure you get the best deal.
  • We recommend you consider lowering the credit limit so you can still use but restrict it somewhat so it stays focused on more essential purchases. Even 13% p.a. interest rates are a high form of finance. 

4 Rules of Low Interest Credit Cards

Before you apply for a low interest credit card, we have outlined 4 rules for doing it right and protecting your finances in the long term.

Prioritise repaying your balance on time (unless you have more expensive debts somewhere else)

A low interest credit card offers the perfect conditions NOT to repay, but unless you're paying off more expensive debt somewhere else it makes complete sense to clear your credit card on a monthly basis. 
​

If you're struggling, make sure to meet the monthly minimum repayments

Your low interest credit card will have a minimum payment of between 2% and 5% of the closing balance. For example, if you owe $1,000 you'll need to pay between $20 and $50 depending on your card's term. If you don’t, you’ll be charged penalties. You should plan to pay more than the minimum unless you have more expensive debt to pay. Read our guide to minimum payments here. 
​

Get your credit score in good condition before you apply

The key when applying for low interest credit cards is to have strong credit; evidence of defaults or late payments will raise red flags for banks who may refuse to accept your application. Read our guide to credit scores and credit reports where you can request your details and fix any errors.
​

Combine a low interest offer with a balance transfer

All of our best buy offers below come with a balance transfer, and they're a great option if you need some breathing space. But, balance transfers work best when you make regular repayments. Divide any transferred balance by 12 (if it's a 12 month offer) and be sure to keep some money aside to make regular installments to pay it off. Otherwise interest is charged from day 1 of the interest-free period ending.

Low Interest Credit Cards Best Practice

  • If you have an existing credit card that you're struggling to pay off, applying for a low interest credit card is a recommended way to keep ongoing interest costs down.
  • Combine it with a balance transfer offer and you can save even more in the short term.
  • Set a credit limit you're comfortable with, and be sure to make MORE than the minimum payments every month to save on interest costs. A direct debit to settle the entire balance owed is the best way to avoid interest charges.
