Formula for federal student loan interest rates
The interest rates on federal education loans are fixed, which means they remain the same over the life of the loan - but each year’s new loans have a new interest rate. The new interest rate is based on the high yield of the last 10-year Treasury Note auction in May. The 10-year Treasury Note auction on May 8, 2019 had a high yield of 2.479%, down from 2.995% the year before.
Congress specified the 10-year Treasury Note in the Higher Education Act of 1965 as the benchmark for federal student loan interest rates because it is the Treasury of closest comparable maturity.
