Ok, so my bill last month was $688. I was short of cash, so I paid $650, and carried the balance to this month. This month purchases total $190. This month bills comes with a finance charge, and the average daily balance (ADB) is $353 as showed in the bill. My questions are:
1. ADB is > than my purchases, so they must have taken $688 into calculating ADB, but wasn't $688 in grace period?
2. As far as I understand, only $38 should accrue interest this month, am I correct?
3. If not, then if one carries balance, new purchases accure interest immediately?
Another question, I have a secured-turned-unsecured BoA CC with AF of $39, I'm too cheap to pay AF, and I no longer have the need for that card, but I can't close it because it's the oldest and highest CL account. They wouldn't change it to another type of CC. They wouldn't increase my limit (student's limit is 2.5k, I have 4.5k), so I figure even if I applied for another card, they wouldn't approve it. Should I close this account? Or should I wait, let's say 3 years, to apply for another card and combine them? What will happen to my report if you combine two cards? Like it would say "combined" or the old account is closed, or what?
Any answers are appreciated.
