The finance charges are both for last month and any new transactions up to the statement date since you lost the interest-free benefit by not paying statement balance in full.

You will be charged interest on the entire balance plus any new transactions and late payment fee until full payment of statement balance. Since this is daily rest, the amount isn't much if you pay the full statement balance now.

@stormaker, yes. No need to bother about outstanding balance to avoid finance charges, just pay statement balance is enough.

@Yello_page, deadline is shown in your screenshot. Statement balance is card balance on statement date while outstanding balance is currently owed amount.
