Frequently Asked Questions

How is a student loan monthly payment calculated?

Student loan payments use the standard amortization formula: M = P·[r(1+r)^n] / [(1+r)^n - 1], where P is the loan principal, r is the monthly interest rate (annual rate / 12), and n is the total number of monthly payments.

What are the current federal student loan interest rates?

For the 2024-2025 academic year: undergraduate loans are 6.53%, graduate unsubsidized loans are 8.08%, and PLUS loans are 9.08%. These rates are fixed for the life of the loan and set annually by Congress.

What is the standard repayment term?

The standard federal repayment plan is 10 years (120 months), which minimizes total interest paid. Extended plans can go up to 25 years. Income-driven plans base payments on your income and offer forgiveness after 20-25 years.

Should I choose Standard or Income-Based repayment?

Standard repayment minimizes total interest with fixed payments over 10 years. Income-Based Repayment (IBR) caps payments at a percentage of discretionary income, ideal if your income is low relative to your debt. Consider your career trajectory and total debt load when deciding.
