In-depth guides and resources to help you make the most of the Student Loan Calculator and master the underlying financial concepts.
Open Student Loan CalculatorStudent loan debt in the United States exceeds $1.7 trillion across 45+ million borrowers, with the average federal loan balance near $37,500 for bachelor's degree recipients. These guides compare repayment strategies — standard 10-year, income-driven repayment (IDR) plans including SAVE, IBR, PAYE, and ICR — and explain the Public Service Loan Forgiveness (PSLF) program for qualifying employment. Understanding the trade-offs between these options can save tens of thousands of dollars over the life of your loans.
The guides detail how 2026 federal student loan interest rates apply (undergraduate Direct Loans: fixed rates set each July from the 10-year Treasury note auction), how capitalized interest compounds when loans are in deferment or forbearance, and how the student loan interest deduction (up to $2,500/year, subject to income phase-outs) reduces your 2026 tax liability. For borrowers weighing refinancing to private loans, the guides explain what you permanently give up: federal protections, IDR access, PSLF eligibility, and deferment options.
