Amex Interest Charges

[jpparker07]

Ok let's see if all your brains can help me figure this one out. 

On my October statement I had a balance of around 1300 on my AMEX BCE that was due on 11/13/13. I accidently missed the day and my auto pay was not set on pay in full just in case an emergency arose. I noticed the balance was still there after the 13th and paid the bill in full on 11/15/13. Knowing I paid in full after the date I expected interest charges to be charged to me on my November statement. My statement came through and the charges were there. I then made sure to pay my new November balance in full by the due date (12/13/13). I thought phew don't want to pay interest charges again. Well I got my December statement today and Amex charged me interest charges on that October balance again for the 14th of November but it was for the same amount I paid in interest in November. For ONE day. I got a refund but the client service person swore this is how the interest worked. So I got charged 10 dollars for the 14th of November which was the same I got charged for the entire month of October.

I work at a bank so I broke down how APR's work and how it couldn't be that much for 1 day of interest but she swore by it. Am I missing something? I will pay in full for sure from now on, but I was very confused. Any ideas?

Have you taken into account that there's no grace period on new charges, if you're carrying a balance?

I was thinking the same thing.  It just wasn't mentioned whether the OP had other charges besides that balance which would have triggered the f/c on the last cycle.

Amex is very peculiar with how they charge interest. It's best to just pay them in full. The balance has to be at $0 for two statements after balance carrying before you get the grace period back, and you must pay in full by due date not statement cutting date. I've learned to just pay in full and not use it so that it always reports at $0 on my credit reports. I do this with BCE and Delta Gold.

By not use it, I mean not use it the week before statement cuts. I def'ly use it a lot and pif lol!
