Credit-card debt is expensive. Bank base rates are the lowest they have ever been (less than 1 per cent in Europe, UK and the US), yet the average interest rate charged on most credit cards today in the UK is around 18.9 per cent annual percentage rate (APR). This means that if you carry £5,000 (about Dh26,400) of debt on the card for one year, you will pay £945. In the UAE, APRs can be as high as 30 per cent, so Dh25,000 of debt will cost Dh7,500 a year. These are eye-watering figures. That interest is money that’s simply lost.
