Most low rate credit cards usually have an annual fee or require good to excellent credit. The interest rates shown are the best possible rates available and may be subject to the cardholder's credit rating. Some interest rates fluctuate as they are based on Canada's prime interest rate. Low interest cards are ideal for those who carry a balance. There are many low interest credit cards that also come with rewards programs, but these cards generally have a higher annual fee. Minimum payments must be met on time each month otherwise your interest rate will increase significantly with most cards.
