Credit card owners who only repay the minimum requirement on their bills every month run the risk of incurring large amounts of debt, it has been suggested.
Consumers have been advised to keep track of their credit card usage by the Consumer Credit Counselling Service (CCCS).
A spokesperson for CCCS pointed out that the interest levied by providers can have a significant impact on credit card bills.
She said: "If they charge you a little [interest] it will become much worse and it can take years to pay off."
Her comments follow in the wake of recent findings released by Which? Money, showing that consumers could rack up their expenses by as much as 200 per cent when making credit card payments due to hidden charges.
A wide variety of purchases, such as cinema, airplane as well as train tickets, can be affected by these charges, often increasing the amount paid by the customer.
