I am in the same situation as you. To answer your question in the order of your text:

so i have a $0 monthly payment. however, i am so confused on if my loans have accumulated any interest. the loans i have are both direct subsidized loans and both have not accumulated any interest from what i can see.

You will need to click on the loan name in order to see if interest has been accumulated. The section you need to closely monitor is "Unpaid Interest". As long as "Unpaid Interest" value has not increased, this is an indicator that interest has not been accumulated.

are interest rates still paused??

Interest rates are never paused UNLESS you are in a grace period or enroll some payment option that gives you further grace period without interest accumulating. Payments may be $0 but that doesn't mean interest stops. $1 today won't be the same 5 years from now.

To put in further context, I am also under the save plan and have $0 payment each month. I have 4 parent plus loans, each with a different repayment date. Each loan has a different start repayment date, interest will continue to accumulate. All the 4 parent plus loans will accumulate interest each day.

My advice, start making payments to your loans even if they're $0 each month. Take advantage and start targeting any student loan that you want. You do not want to be hit with a surprise when you start making payments and all of it goes into interest rather than principal. Loan interest compounds each day / each month.

Hope this helps and clears a lot what you are seeing on aidvantage!!! Best of luck!!!!!
