Roughly 8 million student loan borrowers will see their interest charges restart next month, according to a source familiar.

The Department of Education announced on July 9 that student loans for borrowers in the SAVE plan would start accruing interest on August 1. Their loans, however, will remain in a general forbearance. To avoid interest charges, the Department of Education is encouraging borrowers to switch to another payment plan.

The Trump administration will resume charging interest next month on student loans under the Biden-era SAVE plan, which have been on hold while the plan’s tied up in court—potentially costing nearly 8 million borrowers an extra $3,500 per year in interest.
