BoA Cash Rewards Interest Calculation

[creditconcept]

I have a question.

On the BoA cash rewards card, Is interest calculated on the unpaid balance, or the entire statement balance?

For example:

If my balance is $961.31, And I pay $600

Is interest calculated on the $961 or on $361 (The remainder by the next statement)?

Thanks.....!

Generally speaking, interest is accrued every day for all charges on your card.

If you pay your statement in full before the due date, then you pay no interest.  If don't pay it off in full before the due date, the accrued interest on the balance starting from the charge date will get added to your bill.

The boa calculator is messed up. It said if i was going to pay a 900 balance with 13.9 interest over 4 months,
Id be paying 400 in interest. More 60 dollars.
