Federal student loans are issued by the US government and offer fixed interest rates, income-driven repayment plans, deferment, forbearance, and potential forgiveness programs. Private student loans are issued by banks, credit unions and online lenders — they typically have higher rates, fewer protections and no income-driven repayment options. Always exhaust federal loan options before turning to private loans.
Federal student loan rates for 2024-25: Direct Subsidised and Unsubsidised (undergraduate) 6.53%; Direct Unsubsidised (graduate/professional) 8.08%; Direct PLUS loans (graduate or parent) 9.08%. These are fixed rates set annually by Congress based on the 10-year Treasury note yield plus a statutory add-on. Private student loan rates vary from around 4% to 17% depending on credit score and whether the rate is fixed or variable.
Income-driven repayment (IDR) plans cap monthly student loan payments at a percentage of your discretionary income — typically 5-10% for undergraduate loans under the SAVE plan. The remaining balance is forgiven after 10-25 years depending on the plan. IDR reduces monthly payments significantly for lower-income borrowers but increases total interest paid over time. The SAVE plan (introduced 2023) offers the lowest payments for most borrowers.
A common guideline is to borrow no more than your expected starting salary for your entire degree. If you expect to earn $50,000 after graduation, aim to borrow no more than $50,000 total. Monthly loan payments should ideally not exceed 10% of gross monthly income. Borrowing significantly more than your starting salary creates a debt-to-income ratio that makes standard repayment very difficult and may necessitate income-driven repayment for many years.
The answer depends on your interest rates. If federal loan rates are 6-7% and you can confidently earn 8-10% investing in a diversified index fund, investing the difference may build more wealth mathematically. However, paying down debt is a guaranteed return equal to the interest rate, with no volatility risk. For most borrowers, a hybrid approach works well: maximise 401k contributions (especially with employer match) while making extra loan payments.
Refinancing replaces your existing student loans with a new private loan, ideally at a lower interest rate. This can significantly reduce total interest paid for borrowers with strong credit and stable income. However, refinancing federal loans into a private loan permanently forfeits federal protections including income-driven repayment, deferment, forbearance and forgiveness eligibility. Never refinance federal loans unless you are confident you will not need these protections.
Federal loan borrowers have several options: deferment (temporarily stops payments, subsidised loans do not accrue interest during deferment), forbearance (temporarily reduces or stops payments, but interest continues to accrue), income-driven repayment (reduces payments based on income), and Public Service Loan Forgiveness (PSLF) for qualifying employment. Contact your loan servicer before missing payments — default has severe credit and wage garnishment consequences.
SAVE (Saving on a Valuable Education) is the newest income-driven repayment plan, introduced in 2023. It caps payments at 5% of discretionary income for undergraduate loans (vs 10% under REPAYE). It also eliminates interest accumulation when payments are made as required — so your balance does not grow even if payments do not cover all interest. Forgiveness occurs after 10 years for loans under $12,000, up to 20-25 years for larger balances.
