There is a 1% discount sitting on your student loans. It closes September 30.

The old deal was 0.25% off your interest rate for letting your servicer pull the payment automatically. The new deal is 1% off, and the mechanics are boring in a good way. If you are already enrolled, your servicer applies an additional 0.75% on top of the 0.25% you already had. Nothing for you to do. If you are not enrolled, you sign up on your servicer's website with a routing and account number, free, and the reduction starts flowing.

The fine print worth memorizing: this covers Federal Direct Loans first disbursed after July 1, 2012, for student and parent borrowers alike, and it runs through June 30, 2028. After that it reverts to 0.25% unless the department extends it. So this is a two-year rate cut with a hard enrollment deadline, not a permanent change.

Put it against the actual rates. Loans first disbursed between July 1, 2026 and June 30, 2027 carry 6.52% for undergraduates, 8.07% for graduate unsubsidized, and 9.07% for PLUS. Auto pay turns those into 5.52%, 7.07%, and 8.07%. Federal rates are fixed for the life of the loan, which is normally the end of the conversation. This is the rare case where the number moves in your favor.

Now the dollars, because they scale hard. On the average federal balance of about $40,000, a full point is $400 of interest in the first year, and Student Loan Planner puts the two-year total near $600 as the balance falls. At $100,000 it runs closer to $1,500. At the bottom the math gets thin: the Urban Institute figures a borrower with $5,000 saves roughly $2 a month over a ten-year term. Small balance, small prize. Big balance, a real one. Either way the cost of claiming it is ten minutes.

First, the wrong loan types. FFEL loans, Perkins loans, and consolidation loans that originated before July 2012 are all outside the program. If your debt predates the Direct Loan era you may not have anything to enroll. Second, borrowers in default. You have to bring the loans back into good standing before September 30 to qualify, and that is a longer process than a form, so start this week if it applies to you.

Third, and this one catches people who are otherwise doing everything right: if you are in the new Repayment Assistance Plan and your monthly interest already exceeds your monthly payment, the discount buys you nothing in practice. RAP waives the interest you do not cover. Cutting interest that was going to be waived anyway changes nothing about what you owe. Enroll regardless, because your income and your payment will change and the enrollment window will not reopen, but do not expect the balance to move.

Auto pay is a payment method, not a repayment plan. It debits the amount you already owe on the plan you already picked. What it removes is your ability to forget, which is the entire point, and also the entire risk. The Consumer Financial Protection Bureau's warning is the obvious one: if the account runs dry on the debit date, you are paying overdraft or insufficient funds fees, and those wipe out a $25 monthly saving in a single hit.

Two habits fix it. Set the debit for a few days after your paycheck lands, not before. And keep a small buffer in the account it pulls from, enough to cover one payment you forgot about. If your income is genuinely unpredictable and an automatic debit scares you, that is a fair reason to skip this. For most people it is not.
