Frequently Asked Questions
What is the monthly payment on $30,000 in student loans at 6.53%?
$341 per month on a standard 10-year repayment plan. Total interest paid: $10,932. Total amount repaid: $40,932.
How much interest do I pay on $30,000 student loans over 10 years?
$10,932 in total interest — 36% of the original balance. Making extra payments reduces this significantly since student loans have no prepayment penalty.
Should I pay off student loans early or invest the difference?
At 6.53% interest, compare your loan rate against expected investment returns (~7–10% for index funds). If your rate is below 5–6%, investing extra cash often wins mathematically. Above 7%, paying down debt is typically the better guaranteed return. Refinancing to a lower rate first can change this calculus.
Can I lower my student loan payment if $30,000 feels unmanageable?
Yes — income-driven repayment (IBR, PAYE, SAVE) caps federal loan payments at 5–10% of discretionary income, regardless of balance. Extending the term also lowers payments but increases total interest. Refinancing with a private lender may lower the rate but removes federal protections.
