Starting July 1, federal student loan borrowers who enroll in autopay will pay a lower interest rate on their loans over the next two years, the Education Department announced Thursday.

Currently, borrowers on autopay get a 0.25-percentage-point reduction, but now ED will knock a full percentage point off their interest rates.

The benefit will be given to those already signed up for autopay or who opt in to it before Sept. 30 of this year, Education Under Secretary Nicholas Kent told reporters on a call. It will expire June 30, 2028.
