Quick answer

Federal student loans can be repaid on a fixed standard plan or an income-driven plan that ties payments to your income, and some borrowers qualify for forgiveness programs such as Public Service Loan Forgiveness. Federal repayment rules changed under 2025 legislation, so confirm which plans apply to your loans at StudentAid.gov. Private loans follow the terms in your loan agreement.

Key takeaways

  • Know which loans you have: federal loans offer protections private loans usually don’t.
  • Federal repayment options were restructured by legislation enacted in 2025; availability depends on when loans were disbursed.
  • Income-driven repayment can lower payments but may increase total interest paid.
  • Refinancing federal loans into a private loan permanently gives up federal benefits.

Student loans are often the first major debt Americans take on, and repaying them can span a decade or more. The right repayment approach depends on the type of loans you have, your income, your career and your goals. This guide explains how student loans work and the main options for paying them back. Estimate payments with our student loan calculator.

Important: Federal student loan repayment options were reshaped by legislation enacted in 2025, with changes phasing in over several years. Which plans you can use depends on when your loans were disbursed and the plan you are already in. Always confirm your options with your loan servicer and the official Loan Simulator before making changes.

How student loans work

When you borrow for education, the lender pays the school (and sometimes you, for living costs). Key terms:

  • Principal: the amount borrowed.
  • Interest: charged on the balance. On most loans, interest starts accruing when the money is disbursed. On Direct Subsidized federal loans, the government pays the interest while you are in school at least half-time and during certain other periods.
  • Grace period: a period after you leave school before repayment begins — six months for many federal loans.
  • Capitalization: unpaid interest added to your principal, after which you pay interest on it too.
  • Servicer: the company that handles billing and repayment plans for your loans.

Federal repayment options

Standard fixed payments

A standard plan spreads your balance into fixed monthly payments over a set term. It usually results in the lowest total interest among federal plans. Historically the standard term has been 10 years for most borrowers; under the new rules for newer loans, the standard term can vary based on how much you owe.

Income-driven repayment (IDR)

Income-driven plans calculate your payment from your income and family size rather than your balance. They can make payments affordable when your income is low relative to your debt, and any remaining balance may be forgiven after a long repayment period.

The 2025 legislation created a new income-based plan — the Repayment Assistance Plan (RAP) — for newer borrowers and set timelines for phasing out several older income-driven plans. Some existing borrowers can stay in or move between certain plans for a transition period. Because details depend on your loan dates and current plan, use the official plan pages at StudentAid.gov.

Trade-off: lower payments often mean more interest over time, and in some cases forgiven amounts may have tax consequences. Recertify your income on time each year.

Graduated and extended plans

Some borrowers have access to plans where payments start lower and rise over time, or are spread over a longer term. Availability depends on your loans and when they were made.

Forgiveness programs

  • Public Service Loan Forgiveness (PSLF): forgives the remaining balance on Direct Loans after 120 qualifying monthly payments while working full-time for a qualifying employer, such as government or a 501(c)(3) nonprofit. Use the PSLF tools to certify employment.
  • Teacher Loan Forgiveness: for eligible teachers in low-income schools.
  • Forgiveness under income-driven plans after the required repayment period.
  • Discharges for total and permanent disability, school closure and certain other circumstances.

Private student loan repayment

Private loans follow the terms in your loan agreement. Options may include:

  • Fixed monthly payments over the loan term
  • Interest-only or reduced payments while in school
  • Limited hardship forbearance

Call your lender early if you are struggling — options are more limited than for federal loans, but many lenders have some hardship programs.

Refinancing: when it helps and what you give up

Refinancing replaces one or more student loans with a new private loan, ideally at a lower rate.

  • Private loans: refinancing can make sense if you qualify for a lower rate.
  • Federal loans: refinancing into a private loan permanently forfeits federal benefits — income-driven repayment, deferment and forbearance options, and forgiveness programs. Only consider it if you are confident you will not need those protections.

Federal loans can also be combined through a Direct Consolidation Loan, which simplifies payments but uses a weighted average interest rate (rounded up slightly) rather than lowering it.

Strategies to pay less interest

  1. Pay interest while in school or during the grace period to prevent capitalization.
  2. Enroll in autopay — federal servicers and many private lenders offer a small rate reduction.
  3. Pay extra and target the highest-rate loan. Ask your servicer to apply extra payments to principal rather than advancing your due date.
  4. Use windfalls like tax refunds and bonuses for lump-sum payments.
  5. Check employer benefits — some employers help repay student loans.

On a $32,000 balance at 6% over 10 years, the standard payment is about $355 a month and total interest is about $10,600. Adding $100 a month would pay the loan off almost three years sooner and save about $3,100 in interest. Try your own numbers in the student loan calculator.

Avoiding default

Federal loans generally go into default after about 270 days of missed payments. Consequences can include the entire balance becoming due, wage garnishment, seizure of tax refunds and serious credit damage. If you are struggling, contact your servicer before you miss payments — income-driven repayment, deferment or forbearance may be available.

The bottom line

Start by identifying which loans you have and who services them. For federal loans, compare the standard plan with income-driven options using the official Loan Simulator, and consider forgiveness programs if your career qualifies. For all loans, autopay and targeted extra payments reduce what you pay over time. Explore more in our student loans section.

Frequently asked questions

How do I know if my student loans are federal or private?

Log in to StudentAid.gov with your FSA ID to see all of your federal loans and their servicers. Loans that don’t appear there are likely private; check your credit report and loan documents to identify those lenders.

What happens if I can’t afford my student loan payments?

For federal loans, contact your servicer about income-driven repayment, deferment or forbearance. For private loans, ask the lender about hardship options. Missing payments can lead to default, which has serious consequences for federal loans.

Is Public Service Loan Forgiveness still available?

PSLF remains available to eligible borrowers who work full-time for qualifying government or nonprofit employers and make 120 qualifying payments under a qualifying repayment plan. Use the PSLF tools at StudentAid.gov to track your progress.

Should I pay off student loans early?

If you are not pursuing forgiveness, extra payments reduce total interest — especially on higher-rate loans. Balance that goal against building an emergency fund, capturing any employer retirement match and paying down higher-interest debt.

Are student loan interest payments tax-deductible?

You may be able to deduct up to $2,500 of student loan interest per year, subject to income limits. See IRS Publication 970 for current rules.
