I've never owned one, never had a bank loan, always only ever used debit cards. My parents brought me up to pay within my means so I have zero understanding of credit cards. Anyway, dp and I keep our finances seperate. I own the house outright, he pays the bills. I've found letters from several lenders about credit cards he has. Can someone tell me if he has, say, £10k on a card, what interest/repayments he's likely to be paying? I'm worried he's in a bad situation.
