A credit card differs from a debit card because the money is not taken from your account straight away. The issuer, for example Bank Norwegian or Morrow Bank, covers the purchase, and you receive a single invoice later. You decide whether to pay it in full or spread the amount over time against interest.
Many credit cards come with benefits a debit card rarely offers: travel insurance, purchase protection, rewards or cashback and no foreign transaction fee abroad. TF Bank Mastercard and Bank Norwegian credit card have 0% foreign transaction fee, for example, while Morrow Bank gives up to 4% back on online shopping.
The cost depends entirely on how you use the card. If you pay on time, the card is effectively free on four of the five cards we show, which have no annual fee. If you carry a balance, you pay the effective interest rate, and that is the figure you should compare cards by.
Effective rate 21.66%, NOK 45,000 over 12 months. Cost NOK 4,963, total NOK 49,963.
Effective rate 24.4%, NOK 15,000 over 12 months. Cost NOK 1,849, total NOK 16,849.
