A $30,000 student loan at 5% annual interest repaid over 10 years costs $318 per month, with a total repayment of $38,182. The $8,182 in interest — about 27 cents per dollar borrowed — reflects a below-market rate typical of borrowers who graduated with average undergraduate debt and refinanced to a competitive private rate. The 2024–25 federal undergraduate rate is 6.53%, so a 5% rate usually signals a private refinance or a loan originated during the low-rate years of 2020–21.
Your loan amortizes on a standard schedule: early payments are weighted toward interest, while later payments shift toward principal. In year one, roughly $1,230 of the $3,816 you pay goes to interest. By year seven, more than $2,700 of that year's payments reduces your principal balance. This front-loading explains why making extra payments early has an outsized effect on total interest paid.
Paying even $50 extra per month cuts approximately 14 months off the repayment timeline and saves roughly $1,100 in interest. If your employer offers a 401(k) match, capturing that match first is advisable — it is an immediate 100% return that outpaces the 5% loan cost. Once the match is captured, any surplus is well spent on loan prepayment.

Is 5% a good interest rate for a student loan?
5% is below the current federal undergraduate rate of 6.53% (2024–25) and is typical of private refinance offers for borrowers with strong credit. If your current rate is above 5%, refinancing could save money — though you would lose access to income-driven repayment and federal forgiveness programs.
