I had failed to make a timely credit card payment to Barclaycard XXXX XXXX. This was just a matter of forgetting to pay my bill. 
Received an email notification reminding me of my need to pay and that it was delinquent. My Account balance to pay was {$180.00}, due XXXX/XXXX/2016. My new statement with additional purchases of {$2700.00} arrived with a due date of XXXX/XXXX/2016. My new statement indicated a late fee of {$27.00} which is standard. It also had an interest XXXX of {$34.00} which is for the unpaid balance of {$180.00} and should not be applied to the new purchases until that payment is delinquent. So an interest charge of {$34.00} for {$180.00} equals 18.29 % for 1 month! or 220 % annualized. Check their math!
