Frequently asked questions

What is the difference between federal and private student loans?

Federal loans offer fixed rates, income-driven repayment plans, deferment options, and forgiveness programs. Private loans are credit-based and may offer lower rates to strong borrowers but have fewer protections. Exhaust federal loan eligibility before considering private.

How much is too much in student loans?

A common rule is to borrow no more than your expected first-year salary. If you expect to earn $55,000 after graduation, total loans above $55,000 will likely leave you stretched. The calculator's payment-as-percent-of-income view shows where you fall.

Should I get a co-signer for a private student loan?

A creditworthy co-signer can reduce your interest rate by 1-4 percentage points, saving thousands over the life of the loan. The calculator's co-signer comparison shows your exact savings. Most private lenders allow co-signer release after 12-48 on-time payments.

Is it worth it to refinance federal student loans?

Refinancing federal loans into private loans permanently gives up benefits like income-driven repayment and forgiveness programs. Refinance only if you have stable income, strong credit, and no plans to pursue PSLF or income-driven repayment.

How does income-driven repayment work?

Federal income-driven repayment plans cap your monthly payment at 10-20% of your discretionary income. After 20-25 years of qualifying payments, remaining balances are forgiven (though forgiven amounts may be taxable depending on the plan and current tax law).

What is a good salary-to-loan ratio for graduates?

Most financial advisors recommend that total monthly loan payments stay below 10% of your gross monthly income. If payments exceed 15%, you will likely struggle with rent, retirement savings, and other goals.
