Student Loan Repayment: The Options That Actually Exist

By the StackMargins team · Updated October 2026 · Debt

Federal loans offer a menu—income-driven plans, forgiveness timelines, deferment. Private loans typically come with almost nothing. Know which you hold first.

The federal menu

Income-driven repayment caps federal payments at a share of discretionary income and forgives the remainder after 20–25 years of qualifying payments. For low-income years, IDR beats forbearance—which just lets interest compound while you look away.

Public Service Loan Forgiveness forgives the balance after 120 qualifying payments while working for government or 501(c)(3) employers. The program’s administrative horrors are real; the approvals are also real. Certify employment annually.

Private loans and refinancing

Private loans offer none of that. Refinance only when a materially lower rate meets solid income. Refinancing federal into private is a one-way door that surrenders IDR and forgiveness forever.

Extra payments on any loan go to principal, not future payments—always verify the servicer applied them correctly. Servicer errors are common; only you are checking.

The takeaway: Identify loan types first. Federal—IDR and PSLF protections. Private—refinance math. Never refinance federal protections away for a half-point.

Common questions

Should I refinance federal loans?

Only if you’ll never need IDR or forgiveness and the rate drop is real (>1%). The door closes behind you.

What if I can't afford any payment?

Federal: Apply for IDR immediately—payments can be $0. Never take silent forbearance while income-driven options exist.
