I have a loan which i pay a monthly amount on and a credit card. We have been managing with these payments (just) however the credit cards 0 per cent balance transfer rate is up. We have tried to get another one to change to 0 per cent and computer says no. So if the interest rate is 18.9 per cent how much interest am i looking at paying per month on a balance of £4000? The loan is for 20k, how the hell did i get in this situation?
