<prompt> Human: When I go to pay off my billing group online, I want to ensure my payment only goes to one billing group and is not spread between the two billing groups.The billing group I want to payoff consists of two loans, consolidation 1-13 and consolidation 1-14 with a total outstanding balance between the two individual loans of 13,446.25.There is also another billing group with two loans, consolidation 1-08 and consolidation 1-09. It totals approximately 29,000. I do not want any portion of my payment applied to the loans in this billing group. For my monthly auto payments, the 1-131-14 group pays a single payment and the 1-081-09 group pays a single payment.When I go to the online payment page for Navient, there is a payment box for each loan group two payment boxes total.If I enter the full loan balance for the 1-1314 group of approximately 13,446.25, will that pay off the 1-1314 group in full or will Navient spread my payment across both loan groups?Also, I know there may be additional interest for 2 days because of online payment, but the loan payoff calculator only calculates the amount for all mine loans and not individual loan groups.Cant wait to get these fools out of my life.EDIT: thanks for all of your responses. To clarify how the loans are structured and what I see when I go to pay them off, you can take a look at the pic of the loan payoff page I posted. Im aware of the interest that will accrue online 2 days or via mail 10 days payment. The Navient pay off calculator only lets me calculate the amount for both loan groups and not individual ones. I understand how the process works, Im just generally more frustrated with the cumbersome online portal which is difficult to navigate and doesnt allow for easy payments other than the scheduled ones. EDIT 2: called Navient this morning. After maybe 5-8 minutes of navigating menus, I talked to a representative and they processed my payment for the one billing group over the phone through my checking account. The rep said the payment will post today most likely and that I should get a payoff letter in 30-45 days. I also got an email from western union confirming the payment amount I guess they process Navients payments over the phone. Assistant: Pick up the phone and call them.Human: Yes, I will tomorrow. I was hoping to avoid big-bank corporate phone purgatory for 30 minutes. Was hoping someone had had success paying in full online in this situation  <response>: I actually just did something similar - wanted to pay off all of a specific loan and not split it between two. Called them, was done in about 10 minutes. They really make it pretty easy mostly because they want your money, so you should be fine calling them.
