Pay Off a $30,000 Student Loan at 12% APR

12% APR is severe for student debt, typical of private loans or grad PLUS borrowing rather than standard federal undergraduate rates. On a $30,000 balance at 12%, that rate makes extra principal payments unusually valuable.

Unlike a credit card, $30,000 in student loans at 12% APR doesn't compound daily against itself, interest on this $30,000 balance simply accrues, daily on federal loans, monthly-equivalent at 12%/12 for the purposes here, on the remaining principal. That comes out to about $300 in the first month on $30,000, a figure that falls every month the balance falls under the fixed payment.

The table above shows the fixed monthly payment for each standard term on this $30,000 student loan at 12% APR: shorter terms carry a higher payment but cost less overall, longer terms lower the monthly payment but stretch the interest cost out.

The one variable you control on a $30,000 student loan at 12% APR once the rate and term are locked in is how much extra you send toward principal. Bumping the payment to $530/mo shortens the payoff by about 37 months and keeps roughly $7,231 out of the interest total on this 12% student loan.

Neither federal nor private student loans carry a prepayment penalty by law, so extra principal on this $30,000 balance at 12% APR never triggers a fee. The one thing worth confirming with the servicer on a $30,000 loan at 12% is that any extra payment actually reduces principal rather than just advancing the next due date.

Whether $30,000 in student debt at 12% APR is federal or private changes how the rate got set in the first place. Federal loan rates are fixed per school year by law, the same rate for every borrower who takes out that loan type that year, while private lenders price a $30,000 balance at 12% off the individual borrower's credit at the time of approval.

This $30,000 scenario at 12% APR assumes a fixed monthly payment for the full term, the way the standard 10-year federal plan or a fixed-rate private loan works. Income-driven repayment plans work differently for a balance like this $30,000 one, the payment is set by income and adjusts every year, so the months-to-payoff and interest figures shown for $30,000 at 12% don't apply if that's the plan you're on. studentaid.gov has the current income-driven options for federal borrowers carrying a $30,000 balance at 12%.

If the goal on this $30,000 loan at 12% APR is to actually shorten the payoff timeline, the extra amount has to be flagged for principal, not just sent as a bigger payment.
