So I currently have a credit card that I am paying off, it was 0% on balance transfers when I got it and I haven't spent on it, so I'm paying no interest. However, I now want to make a large-ish purchase (£500), and there will be interest. Can anyone tell me will I be charged interest on the total amount on the credit card? Or just interest on the purchase amount?
I really hope this makes sense. It's a one off purchase and I plan to not use the credit card again after.
