text: let say i have a credit card for limit of a 1000.00 and i make a puchase under. how would they base my payment and if i went over my $1000.00 credit card limit, how would they base my payment. check your agreement, or any billing statement.  it spells that out exactly.  the minimum payment is typically 2.5% to 5% of the ending balance, usually with a minumum of $10.00 or so.  there has been pressure from lawmakers to raise the minimum payments lately to help get people out of debt more quickly.  anything over the credit limit is also due immediately, as are any late fees or over-limit fees.  so, if your credit card has a 4% minimum payment and you were right at the $1,000 limit, your payment would be $40.00.  if you went over your limit by $100.00 and they charged you a $30.00 over-limit fee, your minumum payment would be:  $44.00 (4% of $1,100.00) plus $30.00 (over-limit fee) plus $100.00 (amount you are over the limit)  $174.00 (total minimum payment due)
