Repayment plans
Standard plan (10 years): fixed monthly payments, lowest total interest, but highest monthly cost.

Frequently asked questions
In many countries student loan interest is deductible up to a cap, subject to income limits. The rules differ by jurisdiction, so this calculator shows the gross figures. Ask a tax advisor about your specific situation.
Refinancing a federal student loan through a private lender usually forfeits income-driven repayment and forgiveness options, in exchange for a lower interest rate. If you have stable income and won't need those protections, refinancing can save thousands. Otherwise, keep your federal loans federal.
