My account is on the Income Contingent Repayment Plan, why do my monthly bills show $0.00 amount due?

Based on your reported income level and your loan balance, you are not required to make a monthly payment at this time. However interest still continues to accrue on the loan balance. You may pay any payment amount you wish while your monthly payment is at zero due. As your income increases, your monthly payment amount will increase as well under the ICR Plan.
