Hi all,
Have just started my first claim against a credit card for my mate. She has no PC and as it was me that encouraged her to claim back charges, I offered to do most of the work for her.
She had a limit of £200, and has had the card for 2 years, with £800 of charges added to the balance.
I have a question if anyone can help

about the interest paid on this debt as obviously most of the interest is from the £800 of charges.
I'm filling out the "advanced spreadsheet" trying to work out how much interest she has paid. On the statements there are 2 diff types of interest "cash interest" and "purchase interest". Do I add them together and use that total as the interest charged ?
Sorry for the dumb questions. But the rate for both is the same so i can't figure out why they are listed seperatley on the statements.
thanks in advance
