Key Takeaways
Student loans are the second-largest consumer debt category in the U.S., behind mortgages. They come in two fundamentally different types with very different rules.
Federal student loans are issued by the U.S. Department of Education. Common types:
Federal loans share several features private loans lack:
Private student loans are from banks, credit unions, or specialty lenders. They behave more like regular consumer loans:
Private loans can offer lower rates than federal for borrowers with excellent credit, but you lose the federal safety net.
Federal loans can be enrolled in various income-driven plans that cap monthly payments at a percentage of discretionary income. The plan names and terms have shifted over the years — as of late 2025, SAVE has been in legal limbo and the available plans include PAYE, IBR, and ICR, with specific eligibility rules for each.
IDR makes loans manageable when income is low. The cost: extending the term means paying more total interest over the life of the loan, unless you qualify for forgiveness.
Public Service Loan Forgiveness (PSLF) — After 120 qualifying monthly payments while working for a qualifying employer (government, nonprofit), the remaining federal loan balance is forgiven, tax-free.
Qualifying employment is narrower than it sounds. Verify your employer qualifies through the PSLF Employment Certification Form.
Teacher Loan Forgiveness — Up to $17,500 forgiven for teachers in low-income schools after 5 years.
IDR Forgiveness — Any remaining balance after 20–25 years of IDR payments is forgiven. The forgiven amount is currently tax-free through 2025 (extended under the American Rescue Plan); tax treatment after that date is uncertain.
Borrower defense to repayment — Forgiveness for borrowers defrauded by their schools.
Forgiveness programs are administratively complex. Keep impeccable records, submit paperwork on time, and certify employment annually.
Refinancing federal loans into a private loan converts them to private in every way — you give up IDR, forgiveness, deferment options, and the federal safety net. Only refinance if:
Refinancing private loans into different private loans is fine if it saves meaningful interest.
Unpaid interest on student loans can "capitalize" — get added to principal — at certain trigger events (end of grace period, end of deferment, change of repayment plan). Once capitalized, it earns interest of its own.
Paying the interest during school or deferment periods, even if not required, can prevent capitalization and reduce lifetime cost substantially.
Student loan rates vary widely:
Higher rates merit more aggressive payoff. Lower rates on federal loans, especially with potential forgiveness, often warrant minimum payments while focusing cash on higher-priority goals.
Student loans have a well-documented psychological burden beyond their pure financial cost. Many borrowers benefit from aggressive payoff even when the math favors investing the same dollars. That's a legitimate consideration — a paid-off loan is a durable change that won't be unwound, unlike investment gains.
Student loans in Horizons are modeled with their specific rate and balance, amortizing normally. You can set aggressive payoff via Budget Rules (allocating surplus to debt reduction) or model specific programs like PSLF by setting the liability's end date manually.
