Borrowers can expect to pay more for federal student loans, beginning on July 1.

The federal government sets interest rates on student loans annually, based on a formula adopted in 2013.

The rate on new undergraduate Stafford loans, one of the most popular student loans, will rise to 4.45 percent, up from 3.76 percent this year.

Rates for graduate student Stafford loans will increase to 6 percent, up from 5.31 percent.

And rates on PLUS loans, available to parents, as well as graduate students, will rise to 7 percent, up from 6.31 percent.

The Education Department has not officially announced the new rates, but they can be calculated based on the government’s formula, said Mark Kantrowitz, a financial aid expert. He lays out the math on Cappex.com, a college funding website where he serves as publisher and vice president of strategy.
