These cards offer zero interest on your spending, for a set period of time. They can be a real help if you need to pay for expensive items, such as a wedding dress, a new kitchen or perhaps a holiday. Typically, you can expect to be offered interest free spending for a year or two – but when that period ends you’ll be charged interest on whatever you buy, so it’s important to try to pay off any debt before the interest-free period comes to an end - or you could pay a high rate of interest. Also, don’t forget you will have to pay off the minimum amount each month, as is the usual procedure for outstanding balances.
Additionally, it's very important to take note of the Annual Percentage Rate (APR) before committing to any credit card in the first place, as this is what you'll be charged once your interest free period expires. For example, if the APR on a card is 17 per cent and you spend £1,000 (and don’t pay any of this off), the interest charged for a 12 month period will be £170 on top of your debt - so you’ll pay back £1,170. There could also be other types of fees to take into account, such as late payment charges, if you don’t follow the terms and conditions.
