What is the Payment amount per month? The payment amount per month is the fixed dollar amount that you plan to pay each month until your credit card balance is paid in full. Based on the desired dollar amount that you choose, this calculator will tell you how many months you will have to pay before your balance is paid in full - assuming you do not make any additional purchases before the credit card balance is paid in full. >> Back to the Custom Credit Card Debt Payoff Calculator >> Back to the Main Index
