Find out how much interest you are paying on your existing credit cards. Surveys show that while plenty of us know how much interest we pay in pounds and pence we’re not so good when it comes to percentages.
The card companies probably rely on this because the less we know the harder it is to compare deals. New rules do mean the rates should be printed more clearly on monthly statements so take a look. Anything over around 1.3 per cent a month or 17 per cent a year can easily be beaten.
